COVID Transmission through Aerosols

COVID Transmission through Aerosols

  • Aerosols can be carried in the air for up to 10 m and improving the ventilation of indoor spaces will reduce transmission, a government advisory on stopping the spread of COVID-19.
  • The advisory, issued by the Office of the Principal Scientific Adviser to the Government of India, said there was a need to remember the simple measures that could reduce the transmission of SARS-CoV-2.
  • “Ventilation can decrease the risk of transmission from one infected person to the other. 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 load in the air, reducing the risk of transmission. Ventilation is a community defence that protects all of us at home or at work,” it stated.
  • It recommended adding outdoor air in offices, homes and public spaces. Droplets and aerosols were the key transmission modes of the virus. While droplets fell up to 2 m from an infected person, aerosols could travel up to 10 m.
  • Ventilation in hutments could be improved by adding “jaali or other simple air outlets”, apart from installing exhaust fans, the advisory said.
