Novel coronavirus can spread through air. There is an emerging evidence of the same, as acknowledged by the World Health Organization and Council of Scientific and Industrial Research.
In a blogpost on CSIR's website, Mande referred to findings of various studies and wrote, "All these emerging evidences and arguments suggest that indeed airborne transmission of SARS-CoV-2 is a distinct possibility."
The CSIR chief advised people to avoid large crowded gatherings, keep enclosed places like workplaces well-ventilated and wear masks even in enclosed spaces.
Earlier this month, the WHO had acknowledged the emerging evidence of airborne spread after an open letter by over 200 scientists outlined evidence that showed floating virus particles can infect people who breathe them in.
For months, the WHO had insisted that Covid-19 is transmitted via droplets emitted when people cough or sneeze. Droplets that do not linger in the air, but fall onto surfaces - that's why handwashing has been identified as a key prevention measure.
