Aerosols from Covid-19 infected person can travel in air upto 10 metres: Govt
The government on Thursday issued a set of guidelines to stop the spread of the coronavirus disease (Covid-19) as the country reels under the second wave of the pandemic. The "easy to follow guidelines" highlight the role of masks, social distancing, sanitation and ventilation in the country's fight against Covid-19, according to a release issued by the office of the principal scientific adviser to the government.
Throwing light on how well-ventilated spaces can reduce the risk of transmission from one infected person to the other, the guidelines say, "Just as smells can be diluted from the air through opening windows and doors and using exhaust systems, ventilating spaces with improved directional air flow decreases the accumulated viral land in the air, reducing the risk of transmission."
It is important to remember that those with no symptoms could also spread the virus, the guidelines said. Saliva and nasal discharge in the form of droplets and aerosols are the primary mode of transmission of the virus from an infected person, it added. To prevent this from happening, everyone should continue to wear double masks as these droplets are transmitted while exhaling, talking, speaking, singing, laughing, coughing, sneezing etc.
"Droplets fall within 2 meters from an infected person and aerosols can be carried in the air up to 10 meters," the government said.
The virus infects human hosts, where it can multiply, and in the absence of the host, it cannot survive, the government said. "Stopping the transmission of the virus from a person to another person will decrease the infection rate of the disease to a level where it can eventually die. This can be achieved only with the support and cooperation of individuals, communities, local bodies and authorities. Use of masks, ventilation, distancing, and sanitation, the battle against the virus can be won," it added.
