There has been strong evidence that the virus responsible for corona infection, SARS-COV-2, is spreading through the air. This has been claimed in research published in the medical journal Lancet. Therefore, public health measures are not successful in stopping the virus, because people are vulnerable due to the virus in the air and the infection is getting a chance to spread. Six experts from the UK, US, and Canada have conducted this investigation and gathered evidence. They also include chemist Jose-Luis Jimenez of the Cooperative Institute for Research in Environment Sciences (CIRES).
Jimenez said, "The evidence for airborne infection is very strong and there is little evidence to support a large droplet transmission." The World Health Organization and other agencies working for public health should adopt these scientific pieces of evidence to take steps to prevent airborne infections. ”The team of experts, led by Trish Greenhall of Oxford University, published research. Reviewed and identified evidence confirming airborne infections.
First on their list is the Super Spreader event like Skagit Choir, in which 53 people were infected with one person. The study confirmed that these phenomena cannot be adequately explained by arguments such as close contact or touching the same surfaces or objects. More importantly, the transmission of SARS-CoV-2 is higher indoor than outdoor, and indoor ventilation significantly reduces infection.
The team also underscored that at least 40% of people who do not cough or sneeze have a share in spreading the infection to people without symptoms. This silent transmission is largely responsible for the spread of corona worldwide, which forces airborne transmission. Researchers have also shown that the virus has spread from one person to another even among those present in hotel rooms.
In contrast, the team found little evidence that the virus spreads easily through droplets, which fall through the air and remain on the surface. Lekhkar Greenhalagh said, "Earlier some papers had presented weak facts, but there is now strong evidence about airborne transmission." There should be no delay in taking steps around the world to stop such transmission. ''
New research says that measures such as handwash, surface cleansing to prevent the spread of infection through droplets are not useless, but more attention will have to be given to the spread of the virus through the air. If an infectious virus is airborne, then when an infected person exhales, speaks, shouts, sings, or sneezes, the virus also gets into the air and enters the body of other people through the breath.
What are the remedies?
Research has said that measures to prevent airborne infections include ventilation, air filtration. Stay less in the crowd, should reduce the time spent indoor. Use masks even when living with people indoors, even if there is a distance of six feet. Pay attention to the quality and fitting of the mask. Wear PPE kits of high quality if you live with an infected person.
