A new study examining air samples from hospital wards with Covid-19 patients found that the virus can ‘fly’ as far as 4 meters – twice the recommended safety distance first, aka the safe distance of physical distancing.

They also revealed that the small number of viruses they found at this distance was not necessarily contagious.

The initial study of the investigations by Chinese researchers was published Friday (10/4) in the journal Emerging Infectious Diseases of the CDC.

The results of this preliminary study add to the length of the growing debate about how the disease is transmitted.

The researchers, led by a team at the Military Medical Academy in Beijing, tested surface and air samples from the intensive care unit and the general COVID-19 ward at Huoshenshan Hospital in Wuhan. They accommodate a total of 24 patients between 19 February and 2 March.

As a result, the corona virus is most commonly found on hospital ward floors.

“Maybe it’s because of gravity and air flow that causes most of the virus droplets to fall to the floor,” the researcher was quoted as saying by AFP.

High levels are also found on frequently touched surfaces such as computer mice, bins, bed sides and door knobs.

“Furthermore, half of the samples from ICU medical staff shoe soles were tested positive,” the team wrote. “Therefore, the soles of medical staff shoes may function as carriers.”

Threat in the air

The aerosol distribution of the corona virus is one of the topics debated by scientists. WHO itself currently still sees a small risk of contracting through aerosols. But this team also saw an aerosol transmission.

They found that virus-laden aerosols were mostly concentrated near and downstream of the patient by up to four meters.

They also offer suggestions that contradict orthodox guidelines: “Our findings indicate that home isolation from people suspected of COVID-19 might not be a good control strategy” given the level of environmental contamination.
