Does COVID really transmit through air?
There is consistent, strong evidence to prove that the SARS -CoV-2 virus ,behind the COVID 19 pandemic is predominantly transmitted through air, according to the new assessment published by Lancet recently.
Although some studies in the past have suggested that Covid may spread through air,overall scientific significance would be inconclusive.
In July last year ,a report has been published to the WHO ,saying that there is a evidence that corona virus is airborne.
It is very urgent that the world health organization and other public health agencies should focus is on reducing air borne transmission.
The researchers highlighted superspreader events, such as last year’s Skagit Choir outbreak in the US in which 53 people became infected from a single infected case.
The airborne transmission spread more in indoors rather than outdoor places.
Indoor ventilation can reduce the transmission upto some extent.
The team cited that more than 40% of transmission spread through the people who are not coughing or sneezing.
The silent transmission is the key way that Covid 19 spread to the whole world.
Sometimes,even PPE kit failed to protect the person from infection.
By contrast, the team found little to no evidence that the virus spreads easily via large droplets, which fall quickly through the air and contaminate surfaces.
The new work has serious implications for public health measures designed to mitigate the pandemic.
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.
So airborne control measures include ventilation, air filtration, reducing crowding and the amount of time people spend indoors, wearing masks whenever indoors (even if not within 6 feet or 2 meters of others), attention to mask quality and fit, and higher-grade PPE for healthcare and other staff when working in contact with potentially infectious people.
