Coronavirus particles can be found in the air in places frequented by infected people. This is what shows an investigation published on Monday (4/27) in the scientific journal Nature. Scientists at Wuhan University, the epicenter of the disease in China, analyzed air samples collected at two hospitals that treat patients with Covid-19.

The team found elevated levels of coronavirus in places like a small bathroom used by patients and staff locker rooms. In the staff rooms, after having been thoroughly cleaned, and in the well-ventilated rooms, nothing was found. According to scientists, this suggests that the virus can travel through the air. Research does not respond if these found particles are infectious, but scientists believe they have the potential for transmission.

To avoid this type of spread, the researchers’ recommendation is a good disinfection routine and good ventilation of the environments.

Other studies

Other research has already shown similar results. Until now, the only proven way to transmit the coronavirus is essentially through the airway and physical contact.

But a study published in March by the American medical journal NEJM showed that the coronavirus could survive up to three hours in the form of particles in the air. Another survey, released this week and conducted by the Center for Disease Control and Prevention in Guangzhou, China, indicates that some patients are said to have been contaminated by particles spread by air conditioning in a restaurant.

The World Health Organization, however, says there is insufficient evidence to suggest that Covid-19 is airborne.
