The coronavirus that causes Covid-19 can linger in the air for at least 30 minutes and travel up to 4.5 metres – further than the “safe distance” advised by health authorities around the world, according to a study by a team of Chinese government epidemiologists.
The researchers also found that it can last for days on surfaces where respiratory droplets land, raising the risk of transmission if an unsuspecting person touches it and then rubs their face and hands.
The length of time it lasts on the surface depends on factors such as temperature and the type of surface, for example at around 37C (98F), it can survive for two to three days on glass, fabric, metal, plastic or paper.
“It can be confirmed that in a closed environment with air-conditioning, the transmission distance of the new coronavirus will exceed the commonly recognised safe distance,” the researchers wrote in a paper published in peer-review journal Practical Preventive Medicine last Friday.
