A study published this week by the journal Nature Research revealed that Enclosed areas of two hospitals in Wuhan, China, kept genetic material from the coronavirus floating in the air.
Several public restrooms and rooms where medical personnel changed protective equipment had one thing in common: they lacked ventilation.
The lightest particles of saliva droplets, identified as “aerosol sprays” they were suspended in these rooms until they were registered by biosecurity analyzes.
The report includes microscopic traces of the virus in those rooms during the months of February and March of this year, when the coronavirus was raging in the Chinese city.
Researchers from the State Virology Laboratory and Wuhan University They installed so-called aerosol traps to locate their concentration levels in different areas.
“The levels of SARS-CoV-2 genetic material (RNA) in the air in most public areas were undetectable, except in two crowded areas, possibly due to infected carriers in the crowd,” the study cites.
“We found that some areas of medical personnel initially had high concentrations of viral RNA with aerosol-size distributions that showed peaks in sub-micron and / or super-micron regions, but these levels were reduced to undetectable levels after the implementation of rigorous disinfection procedures. ”
The study indicated that the patients ‘rooms did not register high concentrations of aerosols, but the patients’ bathrooms were especially affected by virus particles that remained suspended in the environment.
“Our results indicate that room ventilation, open space, disinfection of protective clothing, and proper use and disinfection of bathing areas can effectively limit the concentration of SARS-CoV-2 RNA in aerosols.” .
Worldwide, until this Friday, the WHO confirmed more than 3,170,000 cases of coronavirus, including more than 224,000 deaths.
Scholars of so-called aerosols seek to specify what viral conductivity they are capable of transporting, but they argue in advance that the presence of these particles in the environment should be considered a risk.
