Covid-19: IIT Delhi creates ‘risk index’ to implement state-by-state lockdown in India

IIT Delhi has come up with a ‘risk index’ to help the different states of India implement the fourth extension of the Covid-19 lockdown.

The state-by-state lockdown is not an easy task and IIT Delhi has created an identification and mitigation framework to do the same and contain the spread of Covid-19 in India.

It also suggested that Rajasthan, Uttarakhand and Madhya Pradesh are at the highest risk from the coronavirus.

The ‘risk index’ was developed by IIT Delhi’s Department of Management Studies through a research based on proxy measures for severity, likelihood and delectability of Covid-19 for each of the states in India.

How does IIT Delhi’s risk index categorise the different Indian states?

IIT Delhi’s risk index has divided the country into five clusters which will be further sub-divided into the orange, red and green zones. The clusters are High Risk, Medium High-Risk, Medium Risk, Medium-Low Risk and Low Risk.

Among the states identified as in the medium high-risk area by the IIT study are Gujarat, Bihar Maharashtra, Karnataka, Tamil Nadu and Andhra Pradesh.

Delhi, Jammu and Kashmir, Haryana, Punjab, Jharkhand, West Bengal and Chhattisgarh have been identified in the medium-risk cluster.

Why is IIT Delhi’s risk index important?

Professor Arpan Kumar Kar, who led the research, said at a time when the country is stuck in a trade-off between saving lives and saving the economy, the IIT team has proposed a risk identification and mitigation framework for the development and implication of an orderly state-by-state lockdown instead of a complete nationwide lockdown.

“At a specific time, there may not be a better alternative than a complete lockdown to flatten the curve and give the time to the state administration to prepare for the pandemic,” he said.

“While many of the states are still at a very critical stage, it is necessary to examine not only on the basis of total current cases of Covid-19 in states, but at other parameters as well, before planning for further lockdown restrictions,” he expalined.

“Such other parameters would typically gauge a states preparedness to address the aftermath of the pandemic as and when it spreads as well as the probability to get impacted in the long run,” Kar said.

What data did IIT Delhi collect to categorise the different states?

According to Subhadeep Mandal, research scholar at the department, the vulnerability of the state cannot be defined only by looking at the infection and the death rate.

“We cannot describe the vulnerability of a state by just looking at the infected and death rate, hence had to develop a data-driven risk management framework for a broader picture of the situation,” Mandal told PTI.

The researchers considered data from multiple sources such as the count of domestic and foreign incoming travellers, area of the state, average household size, tested-positive rate, tests done per million population, population density, beds per thousand population and the number of testing centres.

“The data for these respective fields were collected state-wise and then broadly classified into three main pillars–severity, likelihood and detectability for the disease. From this, we calculated a risk priority number for every state and union territory where at least one person has been detected positive for Covid-19,” said Arpan Kumar Kar.

“Based on the risk priority numbers of the states, the researchers performed an analysis with an unsupervised machine learning algorithm and divided the country into five clusters of different risk levels,” Kar said.

Covid-19 lockdown extended for the fourth time

The lockdown was first announced by Prime Minister Narendra Modi on March 24 for 21 days with effect from March 25. It was then extended till May 3 and again till May 17.

The lockdown has now been extended till May 31. However, certain relaxations have been provided to start economic activities.

Certain decisions have been left with states and many state governments are yet to announce their respective guidelines.

The death toll due to Covid-19 rose to 3,029 and the number of cases to 96,169 in the country on Monday, registering an increase of 157deaths and a record jump of 5,242 cases in the last 24 hours, according to the Union Health Ministry.
