New Delhi | As a multi-research team from the UK, the US and Canada warned in a Lancet study last week that SARS-CoV-2 virus, which causes Covid-19, is predominantly transmitted through the air, Indian experts on Tuesday said that such understanding already exists and while further research is required to support this claim, people need to be wary of both air and surface transmissions.
The researchers in the Lancet study found little to no evidence that the virus spreads easily via large droplets, which fall quickly through the air and contaminate surfaces.
The study said that if an infectious virus is primarily airborne, someone can potentially be infected when they inhale aerosols produced when an infected person “exhales, speaks, shouts, sings, or sneezes”.
However, according to Indian experts, both the surface (especially indoors) and air modes of transmission have to be factored in while making strategies on how to deal with the deadly virus.
“Recently published Lancet correspondence only gives few directions towards the aerosol mode of spread of Covid. However, there is a lack of experimental evidence in the support of this. Hence, further research is required to support this claim,” Dr Harshal R Salve, Associate Professor at Centre for Community Medicine, AIIMS, New Delhi, told IANS.
