Researchers in China:
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 a surface where respiratory droplets land, raising the risk of transmission if unsuspecting people touch it and then rub their face.
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.
This research is fascinating and ominous. On January 22, an infected passenger boarded a fully booked long-distance coach and settled down on the second row from the back. He stayed on the bus for four hours and the windows remained closed. Reviewing security camera footage, the researchers found the passenger did not interact with anyone else. The person next to him was not infected, but he did infect two people behind him, one person three rows ahead of him, four people who were six to seven rows ahead of him, and one person who got on the bus after the initial passenger disembarked.
