Chennai: The CSIR-Centre for Cellular and Molecular Biology (CCMB) has launched a study in hospital environment to assess how long and far the coronavirus can stay in air from an infected person.
According to CCMB Director Rakesh Mishra, the objective of the study is to know whether the virus actually travels in the air and if it does, how far it goes and primarily intended to help the healthcare personnel.
The study comes two months after more than 200 scientists wrote to the World Health Organisation (WHO), claiming there was evidence that the coronavirus was airborne. Mishra said based on the outcome of the study, CCMB would later take samples from closed halls or public places like a bank or a mall to assess the probability of the spread there.
Meanwhile, the States of Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh and Uttar Pradesh have seen a dip in the R value or the reproductive number during the last week, according to a recent study.
This value has gone below 1 in these high-burden states in the week starting September 19, according to the Institute of Mathematical Sciences, Chennai, and this has helped flatten India’s Covid-19 curve.
Reproductive number is the number of people getting infected by an already infected person on average.
