SARS-CoV-2 Alters Lung Cell Metabolism – IIT Kharagpur Research Model Shows, Model Could Help Therapeutics

  • Model development by IIT Kharagpur researchers predicting alteration in metabolic reaction rates of lung cells post SARS-CoV-2 infection

  • The research would lead to a better understanding of metabolic reprogramming and aid the development of better therapeutics to deal with the viral pandemics

COVID-19 pandemic has been posing unprecedented threats to the whole world. Among its many perils is the cellular metabolic system of those who tested positive. Coronaviruses are known to hijack the metabolism of lung cells. This threat makes it absolutely imperative to understand the mechanism of metabolic reprogramming of host human cells by SARS-CoV-2.

Researchers at IIT Kharagpur have, for the first time, have reported a method to find an alteration in metabolic reaction rates inside lung cells when they are affected by virus/pathogens. As the method finds and reports critical aspects of physiology, which are affected by SARS-CoV-2 infection, it will enable the discovery of therapeutic targets.

“We have used the gene expression of normal human bronchial epithelial cells (NHBE) infected with SARS-CoV-2 along with the macromolecular make-up of the virus to create this integrated genome-scale metabolic model. The growth rate predicted by the model showed a very high agreement with experimentally and clinically reported effects of SARS-CoV-2,” said Dr. Amit Ghosh, Assistant Professor, School of Energy Science & Engineering, IIT Kharagpur.

Scientists have been trying to extract information from the human genome sequences for the past two decades to gather a better understanding of genetic disorders thus allowing us to penetrate deeper into the fabric of life and enable better therapeutics.

Talking about this new development researcher Piyush Nanda (B.Tech.-M.Tech Dual Degree, Biotechnology, 2020, currently a graduate student at Harvard University) explained, “In this model development, we have explored how metabolism works and how it is altered in diseases. Our work involved measuring how the tens of thousands or more complex chemical reactions change when biological cells are intruded on by an uninvited guest like SARS-CoV-2, which would help improve our understanding of diseases.” 

Using the power of genomics the researchers posed the operation of reactions as a set of mathematical equations and solved it to obtain which reactions are altered in the cells when SARS-CoV-2 infects a person.

“A better understanding of metabolic reprogramming would aid in the design of better therapeutics to deal with the COVID-19 pandemic,” remarked Piyush.

Further, the researchers have identified pathways like fatty acid synthesis and lipid metabolism that can be targeted by novel drugs. This model is based on genome-scale differential flux analysis (GS-DFA) in context-specific metabolic models.

“Analysis of the rates of all intercellular metabolic reactions in disease biology is opening up new avenues for therapeutic interventions. Numerous diseases lead to metabolic pathway alterations and it is becoming increasingly important to be able to quantify the difference under normal and diseased conditions. Using our method we have observed the alterations between diseased and normal metabolic states in the case of SARS-CoV-2 infection which have been proven using human patients data. The model will allow researchers to understand the wide spectrum of viruses that manipulate human metabolism and will help to design better therapeutics in COVID-19 treatment leveraging the power of systems biology,” added Dr. Ghosh.

In the case of SARS-CoV-2 infection, the researchers predict that lipid metabolism particularly fatty acid oxidation, cholesterol biosynthesis and beta-oxidation cycle along with arachidonic acid metabolism to be most affected which was confirmed with clinical metabolomics studies.

The research was published in the international journal PLOS Computational Biology

You’re Home: IIT Kharagpur tells international students

Hindustan Times    The Week     India Today     Millennium Post      Outlook     Economic Times      NDTV    Jagran

An early morning tweet on Earth Day woke up a few students at IIT Kharagpur. A fellow Kgpian student, pursuing internship at Georgia, Atlanta, USA, had tweeted seeking help from the Indian authorities in the lockdown situation. Her friends from IIT Kharagpur got in action and shared her message on IIT Kharagpur’s social media handle. Finally the stranded student was connected with IITKGP Foundation, the alumni body of the Institute in USA, who are now trying to help her reach out to the alumni in the region.

Few days prior to this incident, another such call was made for some IIT students stranded in Germany and Sweden. The IITs are reaching out to the alumni in the respective region to connect with these students under distress. International students across the globe are sharing their concerns regarding their fellowships/grants, visa status, residency protocols as the world has come to a standstill with COVID-19 Lockdown. But what is happening at the home front? The Kgp Chronicle presents an account of the international students outreach at IIT Kharagpur.

IIT Kharagpur at present is hosting students and researchers from 12 countries – Afghanistan, Bhutan, Colombia, Ethiopia, France, Myanmar, Nepal, Nigeria, Russia, South Korea, Sri Lanka and Zimbabwe. The Institute is assuring its international students making them feel home away from home while facilitating their academics, stay, residency and other protocols.

The Office of International Relations (OIR) has created an online forum to reach out to the students on a daily basis. The Office shares relevant Institute notices on this forum. The foreign scholars are encouraged to share their concerns and these are addressed as much as possible under these difficult times.

OIR also extended assistance towards extension of visa and processing of scholarship to avoid any disruption of stay and other facilities availed by these students. Some students who have gone home after the mid semester examination are being assisted by the Office and their respective embassies to network with the Ministry of External Affairs, Govt. of India to arrange for their return when the semester resumes. 

“Several international students are receiving financial aid under international programs run by us and outreach bodies of the Govt. of India. We have ensured that they receive their scholarships on time. We are constantly in touch with the students and are committed towards their wellbeing. With every passing day we assure them there is nothing to worry, like every other student, IIT Kharagpur campus is their home away from home,” Prof. Anandaroop Bhattacharya, Associate Dean, International Relations.

Dr. Than Htike Win from Myanmar who is pursuing research work at the Dept. of Metallurgical & Materials Engineering shared his experience during the lockdown period. As his fellowship period gets over at the end of June 2020, he is trying to progress during this phase, in particular the analysis of his research completed till now and planning to finalize the remaining research work and write the reports. 

Solomon Demiss, visiting research scholar from Ethiopia at the Institute’s Dept. of Metallurgical & Materials Engineering has been pursuing his research work through interactions with his guide and fellow team members, reading and writing reports. Solomon was delighted with the gesture of his fellow students to assist him with  procuring necessary supplies from the market while he is managing his  condition of physical challenge and social distancing.

The students are using this isolation period to extensively improve their knowledge base through optimal use of eLearning platforms. Tamim Boubou, who is pursuing MTech in Control System Engineering at the Dept. of Electrical Engineering, was planning to go home to Syria during the summer recess. But now he is utilising the summer-time by attending online video lectures and taking part in summer projects. 

“I actually enjoyed the online video classes, they are more comfortable and in my view are quite interactive, you can record the session and go back to a certain point whenever needed, in short, it is a good experience,” he said. The summer project he has currently undertaken is related to his Masters Thesis Project which is scheduled in the next semester. 

Tamim is excited about the online group created by the Office of International Relations for international students where they are being updated frequently with all new announcements. 

“Almost everyday we are being checked upon, if there is anything missing that we need, same for all mess and hostel facilities, everyone is so cooperative,” he remarked.

Similar thought is echoed by Charles Munyaradzi from Zimbabwe who is pursuing postdoctoral fellowship in biomedical research. Though he has going through acclimatization with the Indian summers and sceptical about his scholarship as his banking formalities got delayed due to lockdown, he appreciates the regular flow of communication  which gives him an assurance in the current circumstances while being in a foreign land.

Several students also plans to seek assistance from the office for renewal of their passport and residence permit, after the lockdown is relaxed and the embassies resume regular operations. 

The students are interacting with their classmates online for joint study, research ideas, games. Some of them are putting their extra time to use by testing their cooking talents. The Office has also provided them with home and kitchen appliances which are useful now during the social distancing period.

Contemplating on the impact of the pandemic situation on the internationalization efforts of IIT Kharagpur, Dean International Relations Baidurya Bhattacharya opined,

“At IIT Kharagpur, we understand internationalization to mean presenting our best to the service of humanity, and in turn, to bring what is best in the world into our campus. Just as this exchange includes the movement of people, it equally well involves the give and take of ideas, free thought and knowledge. As we come out of this pandemic, we will see some short term changes. A lot of national resources will be devoted by every country in rebuilding their economies.  Movement of people will probably reduce somewhat, and that will include faculty and students. But the free flow of knowledge and goodwill between the home and the world will continue.”

The Dean is planning to strengthen and expand the joint academic programs of the Institute with its international partners, conducting more joint research, proposing for more multi-agency grant applications. 

An optimistic Prof. Bhattacharya said, “We will have more online interactions, and we will learn more from each other in how to make the world a safer, kinder and more equitable place – because in the end, we are all in it together.”

Outlook      India Today

IIT Kharagpur has come forward to support the needy people in and around its campus for a period of 6 months. It has set up a temporary fund for those who have been severely affected economically due to COVID-19. The short duration fund is exclusively meant for  about 10500 poor workers on-campus and people coming from villages near the campus who are dependent on IIT Kharagpur for livelihood and are now out of job / no work due to lockdown. The beneficiaries include daily wagers working in different eateries, halls as ward boys, dhobi, small culvert tea shops, rickshaw pullers, maid servants, workers in construction projects etc. Watch Video

Taking stock of the situation and that of the people at the lower strata of the society around the world, eminent alumnus of IIT Kharagpur from the batch of 1967, Vinod Gupta, decided to come forward to help such people associated with his alma mater. Vinod is a US-based entrepreneur and philanthropist who apart from seed funding the management and law schools of IIT Kharagpur has supported many students, staff and faculty and community members on various occasions. 

Director Prof. Virendra K Tewari said, “I thank Vinod Gupta from the core of my heart to have taken the lead and created this fund to help people who are facing dire times. I have known Vinod for 22 years and always observed him to be forthcoming when it comes to helping the needy recalling his humble roots.” 

The IITKGP Foundation in USA under the leadership of President Ranbir Gupta is running this campaign. The Foundation has already raised an amount of USD 2,42,000 (Rs. 1,85,13,242 @ Rs. 76.50) including a pledge of $1,00,000 from Vinod Gupta. Among the other alumni donors are Ranbir Gupta, Arjun Malhotra, R N Mukhija, Rakesh Gupta along with more than 100 donors from 1959 to 2017 batches.

The Institute celebrated this noble initiative on the evening of April 20, by distributing personal protective equipment, ration and toiletries to a small group of beneficiaries to start with, while maintaining social distancing and hygiene protocols. Donate Now

“I salute our alumni, who have always guided us, supported us and above all, remained connected to us. The Alumni Covid-19 Social Welfare Programme funded by our alumni started on the 20th April. We handed over ration and essential toiletries to some of very needy people connected to our campus. Proud to be a part of this mission,” said Prof. Subrata Chattopadhyay, Dean Alumni Affairs.

The alumni community in the USA aims to raise about Rs. 8 crore to help the unsung heroes of IIT Kharagpur campus, confirmed Vinod Gupta. Donate Now.

He further stated, “In 1962, in my first year at IIT, it was a surreal experience for a 16-year-old kid from a village in U.P. When I got sick, the guy who took care of me was the Ward Boy in Patel Hall and his name was Papaya. I still remember him. I remember former US President Bill Clinton, who shared such a nostalgic experience of inviting a porter who took care of him during his university days, to the Presidential swearing-in ceremony. It just shows how important they have been in our lives.” 

Director Prof. Virendra K Tewari has urged every Kgpian to support this noble cause.

He further added, “This is time to reminisce your days at the halls of residence and the mess dada’s smile, your adda at the night canteens and the faces who served you that cup of tea and paratha.”

IIT Kharagpur has set up research funding for R&D work related to COVID-19. The Institute submitted a list of projects to the IIT Council last week of which 8 projects have been selected.

Dr Ramesh Pokhriyal Nishank, Hon’ble Minister, Ministry of Human Resource Development, Govt. of India appreciated and acknowledged the initiative by the Institute on his social media handle congratulating the Director Prof. Virendra Kumar Tewari and his team of researchers.

Talking about the initiative Director Tewari said “It is our responsibility to improve the quality of life of the last person in the society. While we built some quick technologies to cater to the immediate needs of the essential service providers at the campus, we were simultaneously preparing project proposals and evaluating them keeping in mind the immediate need of the country, cost and product delivery period.”

The researchers would be working on several technologies including design and development of rapid diagnostic kit, real-time PCR machine, body suit for COVID-19 patients, personal protective equipment for healthcare workers and portable shredder integrated with sterilizer, Hazmat Suit with forced purified and cooled air circulation for medical professionals, bootstrapping ambu-bag as automated ventilator, telemedicine for fighting viral pandemic, large scale production of recombinant proteins for vaccine and testing.

An amount of Rs. 50 Lakh has been allotted for phase I of 8 projects towards development of prototypes. For most of these projects, the prototypes are expected to be ready within a duration of 3 – 4 weeks, while a couple of them would take about 6 months to deliver the results. The phase I is expected to start immediately after the lockdown is relaxed and the research staff are able to attend the laboratories. Meanwhile software related work would progress as usual.

“IIT Kharagpur has a proven track record towards development of indigenous health and hygiene technologies which are affordable, high-quality at par with globally accepted standards, and commercially viable. Our researchers are committed to deliver the prototypes within a constrained timeline considering the healthcare needs in the current situation,” added Prof. Tewari.

Novel coronavirus – Insights by Prof. Arindam Mondal

COVID-19 infections in India are nearing 15000 cases while claiming more than 100000 lives globally. Coronaviruses are a virus family causing various diseases, ranging from common cold to those like SARS and MERS which can have a high fatality rate. The novel coronavirus responsible for the COVID-19 pandemic is a new strain and has been named Severe Acute Respiratory Syndrome Coronavirus-2 abbreviated as 19-nCoV or SARS-CoV-2.

Dr. Arindam Mondal, Assistant Professor at IIT Kharagpur’s School of Bioscience speaks with The Kgp Chronicle regarding frequently asked questions about novel coronavirus. Dr. Mondal leads the Molecular Virology Laboratory in the School of Bioscience where they study human RNA virus replication and host pathogen interaction on molecular detail to develop novel strategies for therapeutic or prophylactic measures. Currently, his lab focuses upon influenza viruses as a model that causes mild to severe respiratory illness.

1) What is novel coronavirus?

Corona viruses are relatively large viruses ranging from 80-200nm in diameter and having RNA as their genetic material. The outer surface of these viruses contain three surface proteins, namely spike protein (S), membrane protein (M) and Envelope protein (E), while the inner core is constituted of the long genomic RNA enwrapped with multiple copies of viral Nucleoprotein (N). Under the electron microscope, virus particles with spike proteins projecting outwards  form a crown-like appearance, leading to its name Corona (corona in Latin is crown). Recently, during December 2019 several cases of pneumonia like illness with unknown cause was reported from the Wuhan province of China. Later it was found that the disease is caused by a virus belonging to the coronavirus family (Coronaviridae). As this specific type of coronavirus has never been found to infect humans, named as novel coronavirus. 

2) How common are coronaviruses in causing epidemic in the human history?

Human infecting coronaviruses have been known since the 1960s. Coronaviruses like HCoV-229E and HCoV-OC43, HCoV-NL63 and HCoV-HKU1 cause common cold, mild respiratory infections and flu-like illness. First epidemic outbreak of coronavirus was reported  during 2002-2003 caused by Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV). The epidemic originated from the Guangdong Province of China and speeded across 26 countries causing approximately 8000 infections. Subsequently another Coronavirus was reported causing severe respiratory infections in Saudi Arabia and other countries of the Middle east during 2012, named as Middle eastern respiratory syndrome coronavirus or MERS-CoV. For COVID-19, initial cases of “pneumonia of unknown cause” were reported to WHO on December 31st , 2019, from Wuhan in the central Hubei province of China. On January 30th , 2020, the WHO declared the outbreak to be a “Public Health Emergency of International Concern” and recognized it as a pandemic on March 11th , 2020.

3) How is 19-nCoV different from SARS, Ebola, bird and swine flu etc.?

All of these viruses have drawn public attention due to pandemic or epidemics caused in the recent past, such as the 1918 Spanish flu, the 2009 Swine Flu, the 2014 West African Ebola Virus Disease Epidemic and the 2003 SARS epidemic. While bird and swine flu were caused by different subtypes of influenza viruses, Ebola virus causes hemorrhagic fever. The novel coronavirus, recently identified to have been originated from Wuhan province of China, is closely related to the SARS-CoV (Severe Acute Respiratory Syndrome Coronavirus) that caused the 2002-2003 epidemic, and has thus been alternatively designated as SARS-CoV2. Like the SARS-CoV that originated from bats and got transmitted to humans via an intermediate mammalian host (civets), the SARS-CoV2 seems to have jumped host species from bats to humans, although the existence or identity of the intermediate host is yet to be elucidated. Recent reports have identified pangolins as the possible intermediate host.

The SARS-CoV-2 strain is similar to the 2009 Swine Flu virus (Influenza A- H1N1) or the seasonal flu virus only in a few aspects, such as transmission via close contact, bodily secretions, respiratory droplets during coughing, sneezing or talking, and fomites and the general symptoms similar to common cold like fever, headache, joint and muscle pain, sore throat, runny nose, a typical dry cough. Early evidence shows that although it is more contagious than the seasonal flu or the Ebola Virus or SARS-CoV that caused epidemics, it is less deadly. While SARS-CoV-2 has a variable case fatality rate of 2% depending on age, geographic location, extent and criteria for testing, the Ebola virus and the SARS-CoV has case fatality rates of 40% and 10% respectively. Several infected individuals developing only mild symptoms or even being asymptomatic at times. Also, the major target age groups for the 2009 swine flu were children between 5 and 20 years of age, for the COVID-19 it is mostly older individuals above 60 years of age and immunocompromised people or people with other complications such as cardiovascular diseases, hypertension or diabetes, much like the SARS-CoV.

4) What is the activity cycle of the novel coronavirus?

Coronavirus life cycle initiates with the interaction of surface spike proteins with the receptors on host cells. The spike protein of novel SARS-Coronavirus-2  recognizes host ACE2 (Angiotensin Converting Enzyme 2). The spike protein of this virus has significant similarity with two coronavirus strains that infects bats. Hence, it is assumed that the current strain of the novel coronavirus got adapted to infect humans through adaptation in its spike protein. Usually, these kind of novel viral strains, as they are unknown to the humans immune system, may cause severe infection, as happening currently.

Interaction of viral spike protein with the host cell receptors leads to entry of the novel coronavirus into the host cell, followed by uncoating of the outer envelope to release of viral genomic RNA. The viral RNA then utilizes host machinery to synthesize viral proteins. Some of these newly synthesized viral proteins (RNA polymerase/ replicase) then carry out genome replication to produce more copies of progeny viral genomes. Another set of viral proteins then assembles with these progeny viral genomes to generate a large number of progeny virion particles. 

5) For how long can this virus remain active on an inorganic surface?

According to recent reports, the new COVID-19 coronavirus can remain stable in aerosols and on various surfaces for several hours, indicating plausibility of aerosol and fomite-borne transmissions. The SARS-CoV2 can remain viable in aerosols for up to 3 hours, up to 4 hours on copper, up to 24 hours on cardboard and for the longest duration of up to 72 hours on plastic and stainless steel, although its infectivity reduces with time. This further highlights the importance of frequent hand sanitization and not touching the face or mouth after touching surfaces.

https://www.nejm.org/doi/pdf/10.1056/NEJMc2004973?articleTools=true

6) Social media is buzzing with the news that the virus would weaken with rise in temperature? Is there any scientific truth in this statement?

In 2002-03 during the SARS epidemic, it was observed that rising temperature and relative humidity did affect the spread of the virus by rapidly declining its viability. In case of COVID-19 pandemic, it has been observed that the virus spread is more rampant in regions of lower temperature (5-11°C) and moderate humidity (50-70%). Experts also noted that the duration of sunlight, which determines the duration of UV exposure to the virus, could be a determining factor as it is UV-sensitive. Some studies under review also suggest, laboratory grown strains of 19-nCoV could be sensitive to extreme heat, but that will not suffice to explain its expected behavior in a pandemic setting, influenced by unpredictable human factors. However the jury is still out on whether the temperature rise and monsoon will be able to significantly subdue the outbreak.

7) Recently India has been getting orders for hydroxychloroquine by countries severely affected by the virusIs it the ultimate antiviral remedy for novel coronavirus?

Several antivirals have been identified that could combat the virus by interfering with different stages of the viral life cycle, for example, uncoating inhibitors chloroquine and hydroxychloroquine, replication inhibitor Remdesvir, RNA polymerase inhibitor Favipiravir and so on. Although, specific mechanisms of these antiviral drugs are still under investigation.

Dr Arindam Mondal’s group in collaboration with Prof. Suman Chakraborty’s laboratory at the Mechanical Engineering Department, IIT KGP, is currently trying to develop of a paper-strip kit for rapid low-cost diagnostics of COVID-19 infection. This is a portable rapid diagnostic kit, which in combination with a smartphone app, can be deployed at community level in order to carry out extensive detections for the SARS-CoV-2, the causative agent of COVID19.

VGSOM Assigns COVID Case Study

IIT Kharagpur’s Vinod Gupta School of Management assigns Pandemic Case Study for Organizational Leadership education

It has been almost 2 weeks since the teaching and learning at IIT Kharagpur has gone virtual. The Center for Educational Technology at the Institute has been using the online interface Webex for conducting classes across all levels of study. Shorter sessions are also being conducted through Zoom. 

Several research groups are also conducting studies on people’s perception and behaviour towards COVID-19 through progression of time. In one such initiative, the Vinod Gupta School of Management, business school in India of IIT Kharagpur ranked among the top ten in India, has launched a project based on COVID-19 pandemic. The project titled “Invisible Leadership and the CoronaVirus Pandemic” is being assigned 126 students in the second year MBA class at the School as part of the Organisational Leadership course.

Speaking about the project Prof. Susmita Mukhopadhyay said, “Pandemic or any other wide spread disease such as COVID-19 demand exemplary leadership and decision-making capabilities to manage finances, human resources, supply chain and overall business operations. Managers if prepared for desperate times may even plan and improvise the desperate measures. The project aims to teach the students to see the power of invisible leadership in the fight against a pandemic.”

“Leadership is more about taking tough decisions now while keeping the greater good in mind than appeasing your countrymen with misleading information. Covid-19 has turned every one of us into soldiers fighting for the very survival of our species and the real leader here is invisible. So when we miss the leader micromanaging things, we look inward for leadership,” said Pinak Samui, student at VGSOM.

The students will be studying the facts from diverse shades of leadership and understand the ethical issues connected to such situations as COVID-19 pandemic. They will also explore whether the Pandemic itself has acted as an invisible leader in enhancing work-life balance of people, cohabitation of species and environmental sustainability.

“We have given the topic to the students to have a free flow of thought and explore the topic from various perspectives, frame the case based on archival news and keep track of day to day developments and strategies undertaken by governments and other related stakeholders. We plan to develop business case studies based on the project output,” remarked Prof Biplab Datta.

Student Feedback:

“This assignment has helped us to keep track of the COVID-19 situation and all related happenings as they are happening around the world. It also helped us to dive deep into the invisible leadership principle and apply the same, in order to add a new perspective to the current situation, just like looking through a different lens,” said a student Pritam Sharma.

 

Sharing about his learning, another student Aniket Sanyal said, “Leaders, who can take quick actions, who are flexible in adapting their bold decisions to suit the needs of a situation, will have more success in a crisis environment.”

Kgp Hacks Corona

IIT Kharagpur’s Undergraduate Students Council has launched KGP Hacks Corona, an initiative for the IIT KGP community to build software and data solutions aimed at tackling various challenges related to the COVID-19 pandemic.

The objective as stated by Council representative Santosh T.Y.S.S is not only to engage the students during the isolation period but also create an online space where developers can ideate, experiment and build software solutions.

Study@COVID-Time with NDLI

IIT Kharagpur develops JEE Preparation Module on NDLI during COVID-19 Lockdown

Times of India          Navbharat Times         Times Now         Education Times          India Today         NDTV       Jagran Josh          DataQuest      NDTV Khabar  

In a recent announcement JEE Main and NEET UG have been postponed till last week of May 2020 with Shri Ramesh Pokhriyal Nishank, Minister, Human Resources Development, Govt. of India urging students to prepare further for these examinations during this period. While the decision for the postponement was expected, students now need adequate online resources and e-learning materials to continue with their preparation. 

IIT Kharagpur has been quick to address the issue by developing a preparatory module for JEE available to students for free on the National Digital Library of India platform.  Students can visit the NDLI website https://www.ndl.gov.in/ or https://ndl.iitkgp.ac.in/ or log on to the NDLI mobile application. A special module named ‘Corona Outbreak: Study from Home’ has been added to the website which contains a wide range of digital content including those preparing for competitive examinations like JEE Advanced. The repository contains NDLI Tutorial for JEE Advanced for 12 years and Practice Questions and Solutions for JEE Preparation. Content for JEE Mains for 5 years is expected to be made available soon.  

“The solutions have been prepared from the perspective of undergraduate students who have cleared JEE as well as subject matter experts and doctoral students in related areas. Hence the solutions are diverse and students can opt for their preferred methods. Further we have provided reference materials for related problems, so students can explore further the topics,” explained Prof. Partha Pratim Das, Joint-Principal Investigator, NDLI.

Students can browse the School option under the Corona Outbreak module or search by relevant keywords. The developers recommend registering on the portal for better user experience though the resources are available without any restrictions.

“Please visit and continue your studies. Please let us know how we can continue to support your preparations. NDLI is accessible through the web as well as mobile App. Be safe but let us be digitally active in academics and connected,” says Prof. P P Chakrabarti, Principal Investigator of NDLI, on his social media handle. He further urges to reach out to students who can be immensely benefited from this platform during this lockdown period. “Digital Libraries have become the next generation paradigm for people to empower themselves with knowledge and contribute to the knowledge gathering of this world,” he added.

NDLI was developed by IIT Kharagpur under the aegis of Ministry of Human Resource Development, Government of India in the year 2016 as a National Mission project. MHRD has been promoting various e-learning platforms since the academic activities have been restricted in educational institutions earlier this month due to CoronaVirus outbreak. NDLI has been at the forefront of such e-learning platforms with over 4.8 crore content in more than 300 languages that can be viewed in 60+ formats apart from e-books (audiobooks, simulations, e-thesis, question papers etc.). The platform has over 55 Lakh users.

“The project, which has been collating content to democratize education for India, has shaped up to be the most promising initiative on the future of libraries from India and symbolizes a strong voice to tell the story from India’s standpoint,” added Prof. Das. 

Exploring COVID Lockdown

IIT Kharagpur Study Explores the Urgent Need for COVID Lockdown

Times of India             Hindustan Times            Economic Times             NDTV            Outlook           Edex Live               India Today           Business Standard       Times Now         Hindustan Times (PTI)          Amar Ujaala                                                      


IIT Kharagpur researchers have taken an initiative to carry out a study on travel and social distancing perspectives of Indian citizens during the recent outbreak of COVID-19. The study throws light on understanding people’s preparedness in case of a lockdown, their travel behaviour and their perceptions during COVID-19 outbreak and assessing impact of travel restrictions and social distancing on different aspects of life as per people’s perceptions. 

The study was conducted by Dr. Saurabh Dandapat, Dr. Kinjal Bhattacharyya, Annam Sai Kiran, Kaustubh Saysardar, researchers at IIT Kharagpur’s Ranbir and Chitra Gupta School of Infrastructure Design and Management, Dept. of Civil Engineering, and mentored by Professor Bhargab Maitra. It covered 400-plus cities in 28 states and 4 UTs of India upto March 22, 2020. The work will eventually help formulate potential strategic interventions and policy measures for combating any future events of similar nature. It also aims to formulate and assess the likely effectiveness of different strategic interventions pertaining to travel and social distancing for minimizing the spread of COVID-19. 

Explaining the need for the lockdown, Prof. Bhargab Maitra remarked, “It was alarming to note that nearly 20% respondents expressed their desire to leave the current city of work in case of announcement of city lockdown. Such acts would increase the risk of spread of COVID-19 in other places and therefore, justify the action taken by the Government of India in terms of one day ‘Janata Curfew’ and successive lockdown of several cities and towns by various State Governments.”

However, a positive indication in the report is the steady rise in the number of respondents opting for work from home from less than 40% to over 75% within a week’s time.

“Another positive note is that the study showed a significant share of respondents (i.e., over 30%) was aware about possible city quarantine and were getting prepared for it. The ‘Janata Curfew’ was a positive step for further awareness and preparedness about quarantine, and provided a doorway for implementation of lockdown in several states,” said researcher Dr. Saurabh Dandapat.

Researchers also observed that the awareness among the people about the risk of travel in public transport has increased over the time, possibly due to strong campaigns carried out by the Governments and wide coverage of COVID-19 cases by the media.

“Data reflect that while on 17th of March 2020 only about 60% respondents were considering cancellation/postponing long distance travel for various purposes such as healthcare, work, family/social, and vacation, the share increased to 75% on 22nd March 2020. Although this indicates a positive attitude, however, a significant share of respondents was still planning to travel which might increase the risk of spreading the virus,” said researcher Dr. Kinjal Bhattacharyya.

The researchers Annam Sai Kiran and Kaustubh Saysardar recommended creating more awareness among a section of citizens communicating the need for the lockdown. The study postulates the need for more stringent measures to restrict the movements even within the cities under lockdown to counteract the lack of awareness among a section of the society. It is now also necessary to boost the awareness campaign and the media can play a big role by increasing their self-initiatives with respect to awareness campaigns alongside publicizing the Government driven campaigns. 

Based on the recent lockdowns and other efforts being taken by the Central and different State Governments, the questionnaire has now been updated to understand the perceptions and reactions of the citizens under current scenario and provide further inputs which might be of help to the Government to make further informed decisions.

Additional information

The respondents’ were asked to provide details about their regular travel, travel characteristics during COVID-19 outbreak, their perception regarding safety against spread of COVID-19 during travel by different modes, impact of COVID-19 outbreak and travel restrictions on different aspects of their life, their travel plans in the case of lockdown of cities and during the initial period once the travel restrictions are lifted, and demographic and socio-economic characteristics. 

The research team analyzed more than 3,400 responses obtained from 400-plus cities in 28 states and 4 UTs of India. The database covers respondents from different segments of the society in terms of income groups, profession, and age groups. The data are being analyzed over the time and the questionnaire is being updated according to the changing scenarios in order to capture the real time responses. The analysis indicates several interesting observations.
