India's COVID19 case tally crossed 20-lakh mark with highest single-day spike of 62,538 cases. The COVID19 tally rises to 20,27,075 including 6,07,384  active cases, 13,78,106 cured/discharged/migrated and 41,585 deaths. The total number of COVID19 samples tested up to August 6 is 2,27,24,134 including 5,74,783 samples tested on Thursday.

In a first-of-its-kind study, air samples from intensive care units, hospital corridors, waiting rooms and places where healthcare workers are most at risk will be collected and investigated to understand whether airborne transmission is contributing to the Covid-19 pandemic.

The study comes close on the heels of a letter that was sent by 239 scientists from 32 countries to the World Health Organisation (WHO) about the mounting evidence the airborne route plays in the transmission of Covid-19.
