Ventilation and Covid-19

Ventilation and Covid-19

Letting fresh air into indoor spaces can help remove stale air that contains virus particles, and help prevent the spread of COVID-19.

When someone with an active COVID-19 infection breathes, speaks, coughs or sneezes, they release particles containing the virus. While larger droplets fall quickly onto surfaces or the ground, aerosols containing the virus can remain suspended in the air. If someone breathes in virus particles that are suspended in the air, they can become infected with COVID-19. This is known as airborne transmission.

In poorly ventilated rooms the amount of virus in the air can build up, increasing the risk of spreading COVID-19. More so if there are lots of infected people in the room. The virus can also remain in the air after an infected person has left.

This winter opt for keep air circulating.
For any gatherings, choose an outdoor setting or open windows/ doors (weather and safety permitting). Even short bursts of window opening, for 10 to 15 minutes, can make a big difference.
