LONDON: A new public information campaign launched by the Government to highlight how letting fresh air into indoor spaces can reduce the risk of infection from coronavirus by over 70%*.

The campaign, which forms part of wider ‘Hands. Face. Space’ guidance, sees the release of a new short film created with scientists and an engineer at Leeds University.

The film illustrates how coronavirus lingers in the air in spaces with no fresh air, increasing the risk of people breathing in infected particles, and how the risk can be reduced significantly by regularly ventilating enclosed areas.

As we spend more time indoors, experts are recommending that the public open windows for short, sharp bursts of 10 -15 minutes regularly throughout the day, or leave windows open a small amount continuously, 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.

Professor Catherine Noakes, from Leeds University who advised on the film, said: “When a room does not have any fresh air, and where people are generating large amounts of aerosol through activities such as singing and loud speech, that is when transmission of coronavirus is most likely. Fresh air must come from outdoors – recirculating air just means the aerosols containing the virus move around the same room rather than being extracted outdoors.

GP, Dr Amir Khan said: “As we approach winter, and inevitably spend more time indoors, fresh air is extremely beneficial. For COVID-19, it is important to ventilate indoor spaces if someone in your home has the virus as this can help prevent transmission to other household members. “You should also let fresh air into your home when you have any visitors and just after they leave in case they are infected. Remember, opening windows alongside washing your hands, covering your face and making space is also essential in reducing your risk of COVID-19.”
