“Since there is a rise in air pollution, there is data to state through certain modeling studies from China and Italy (Europe) which show that in areas where there is even a little bit of increase in PM 2.5 levels, it leads to a surge of at least 8-9% in coronavirus cases”, Gulerai said in an exclusive interview to India Today.

Besides a study titled “COVID-19 spread in India and its dependence on temperature and relative humidity had claimed that every degree rise in temperature corresponds to a 0.99% decrease in the number of cases and an increase in doubling time by approximately 1.13 days, implying a slowing down of spread,
The study, led by V. Vinoj, Assistant Professor of the School of Earth, Ocean and Climatic Sciences at IIT-Bhubaneswar, examined the relationship between Covid-19 spread and environmental factors such as temperature, relative humidity, specific humidity, and solar radiation.
The results showed that temperature and relative humidity have a significant impact on the disease growth rate and doubling time, according to the abstract of the study posted on ResearchGate, a professional network for scientists and researchers.
Meanwhile, India’s tally of COVID-19 cases went past the 68-lakh-mark with a total of 68,35,655 cases.
