Video: Importance of ventilation to reduce spread of COVID-19

A new short film released by the government shows how coronavirus lingers in enclosed spaces, and how to keep your home ventilated.

  • Research shows that being in a room with fresh air can reduce the risk of infection from particles by over 70%
  • The film is part of the ‘Hands. Face. Space’ campaign which urges public to adopt simple health behaviours to help reduce the risk of the virus spreading

Research shows that being in a room with fresh air can reduce your risk of infection from particles by over 70%, as fresh air dilutes the particles. As we spend more time indoors, experts are recommending that people either:

  • open windows for short, sharp bursts of 10 to 15 minutes regularly throughout the day
  • leave windows open a small amount continuously

This is to remove any infected particles lingering in the room. Additionally, it is advised that any household systems that use outdoor air, including kitchen or bathroom extractor fans, are used correctly and regularly as an additional method to remove infected particles.

Airing indoor spaces is particularly important when:

  • people have visitors (when permitted) or tradespeople in their home, for example for construction or emergencies
  • someone from a support bubble is meeting with another household indoors
  • a care worker is seeing a patient indoors
  • someone in the household has the virus, as this can help prevent transmission to other household members.
