The silent transmission of Covid-19 has made the situation worse. The virus is wreaking havoc globally. According to a new assessment carried in the popular medical journal The Lancet, the SARS-CoV-2 virus is predominantly transmitted through the air. The SARS-CoV-2 virus causes Covid-19 disease. It said that strong evidence and data are available that show that the virus is transmitted through the air. Several past studies suggested that Covid-19 infection may spread through the air. However, it could not be confirmed as studies were inconclusive. The latest claim is based on an analysis made by six experts from the US, Canada, and Britain. They said that measures failing to treat the infection are only leaving people unprotected and allowing the virus to spread.
Back in July 2020, more than 200 scientists from 32 nations had written to the World Health Organization that there is evidence available suggesting Covid-19 is airborne. They submitted that smaller particles too pose a serious threat and can infect people. It noted that WHO and other world agencies should urgently take note of scientific evidence and focus on mitigation. It called for tough measures to reduce airborne transmission. The assessment added that transmission of virus multiplies indoors than outdoors. It said that transmission from people not showing symptoms like sneezing and coughing accounts for 40 percent of all transmission. This makes the infection a serious threat for healthy people and affects mass.
Researchers find no evidence that SARS-CoV-2 spreads easily through large droplets. They said that large droplets fall through the air quickly and make the surface contaminated. They cited long-range transmission between people in adjacent rooms in hotels. They said that the virus even affects people who were never in touch. Researchers said that robust measures should be implemented without any delay to check the airborne transmission. They said that hand hygiene and surface cleaning are important but the emphasis should be on airborne measures because inhalation of the virus will only give a rise to infection. They added that covering the face with a mask can prevent droplets from traveling through air, but not all masks are effective.
