While inside, it may be a good idea to take a few more steps back.
On Tuesday, experts said they believed the six-foot distance proposed by the World Health Organization (WHO) may not be enough to limit the Kovid-19 infection.
In this Perspective article published in the journal Science, Three experts wrote that aerosol particles can frequently infect indoor air and easily breathe deeply into the lungs.
“Additional evidence in favor of SARS-CO-2 is that the WHO’s recommendation of several feet may not be sufficient under many indoor conditions where it can remain airborne for hours, accumulate over time and follow wind flows over a distance of more than 6 feet,” they said. They said.
Chia Wang of Taiwan’s National Sun Yat-sen University, as well as the Kimberley Practice of the University of California, San Diego, and Dr. Robert Schulley say a large part of the spread of COVID-19 appears to be caused by airborne infections of aerosols. They were produced by imperfect individuals while adding breathing and speaking.
On Tuesday, experts said that in order for society to resume normalcy, measures must be taken to reduce aerosol infections, including minimal testing as well as public wearing of masks. They believe that both practices can help identify and isolate an infected person.
They added, “It is especially important to wear masks in places where high concentrations of viruses accumulate, such as in healthcare settings, aircraft, restaurants and other crowded places with reduced ventilation.
The outlook article states that countries such as Taiwan, Hong Kong, Singapore and South Korea have implemented universal masking and were most effective in reducing the spread of COVID-19.
The six-foot social distance guideline by the WHO is based on a study of breathing drops in the 1930s. However, the technology for detecting tiny aerosol particles did not exist, experts said.
Smaller aerosols will evaporate faster than settling, they added. That is why they can be exposed to wind currents, which can cause them to travel long distances and stay in the air for hours.
“Most of the evidence points to aerosol infections in respiratory virus infections,” Pathar told WebMD. “This particular virus, the evidence is growing.”
This month, a Study Scientists in Hong Kong have discovered that the use of surgical masks can reduce the rate of non-contact by breathing particles or airborne particles by up to 75 percent.
