Covid-19 pandemic: Ventilate, open windows to cut risk, advises UK government

Hindustan Times  

The Boris Johnson government on Wednesday released a new film based on research that shows ventilation and letting in fresh air into indoor spaces can reduce risk of infection from the coronavirus by over 70%. The film produced with scientists at Leeds University 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. Experts recommend opening windows for short, sharp bursts of 10 to 15 minutes regularly throughout the day and to leave windows slightly open continuously to remove infected particles lingering in the room. They also 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.
