The coronavirus may be able to linger in the air for at least half an hour, last for days on some surfaces, and travel almost 15 feet, a new study has found.
The research by Chinese government epidemiologists challenges the advice of health authorities who have suggested staying a “safe distance” of between 3 and 6 feet apart in public spaces to avoid catching COVID-19, according to the South China Morning Post.
“It can be confirmed that in a closed environment with air-conditioning, the transmission distance of the new coronavirus will exceed the commonly recognized safe distance,” the researchers wrote in a paper published in peer-reviewed Chinese journal Practical Preventive Medicine last Friday, per the newspaper.
The researchers from the Hunan province say they found the virus could last for days on a surface, depending on the environment. For example, at 98 degrees, they found it can last two to three days on glass, fabric, metal, plastic or paper.
It can also survive more than five days in human feces or bodily fluids, they said.
The scientists based their findings on a Jan. 22 case of a person with the virus who took a long-distance 48-seater bus ride — and ended up infecting 13 people total, according to the SCMP.
Surveillance footage showed that the patient didn’t interact with others throughout the four-hour ride — but a couple of the people who became infected were sitting as far as six rows away, or about 15 feet, the researchers said.
