Aerosols and droplets are key transmission mode of the virus, and while droplets fall within 2 meters of infected person, aerosols can be carried up to 10 meters, an advisory said

NEW DELHI

Cautioning people to maintain social distance to prevent the transmission of the Covid-19 virus, the office of the Principal Scientific Adviser to the Government of India on Thursday said that aerosols, one of the key transmission mode of the SARS-CoV-2, can travel in the air up to 10 meters.

“Aerosols and droplets are key transmission mode of the Covid-19 virus, and while droplets fall within 2 meters from an infected person, aerosols can be carried in the air up to 10 meters,” an advisory said.

The “Stop the Transmission, Crush the Pandemic – Masks, distance, sanitation and ventilation to prevent the spread of SARS-CoV-2 virus” advisory highlights the important role well-ventilated spaces play in diluting the viral load of infected air in poorly ventilated houses, offices and other closes spaces and said ventilation can decrease the risk of transmission from one infected person to the other.

Calling ventilation “a community defence” against the spread of the novel coronavirus, it says “Just as smells can be diluted from the air through opening windows and doors and using exhaust systems, ventilating spaces with improved directional airflow decreases the accumulated viral land in the air, reducing the risk of transmission.”

The Office of Principal Scientific Advisor in a release has advised introducing outdoor air in offices, homes and larger public spaces and said measures to improve ventilation in these spaces must be taken up on urgent priority in urban and rural areas alike.

“..recommendations for hutments, homes, offices and large centralised buildings are given. Simple strategic placement of fans, open windows and doors, even slightly open windows can introduce outdoor air and improve the air quality inside. The introduction of cross ventilation and exhaust fans will be beneficial in curtailing the spread of the disease,” it stated.
