Covid-19 only stays in the air for a short time, says WHO chief scientist Dr Soumya Swaminathan


Covid-19 will only stay in the air for a short time, says WHO chief scientist Dr Soumya Swaminathan. At the same time, a group of more than 230 scientists from 32 countries around the world has claimed that Covid-19 can also spread through the air. After which the concern about it in people’s minds increases. taking World Health Organisation (WHO) to update its guidelines.

To dispel any doubts about this new discovery about COVID-19, Dr. WHO chief scientist Soumya Swaminathan, in an exclusive interview with India Today TV editor Rajdeep Sardesai, explains a few things related to it. When asked about WHO’s position on whether COVID-19 is airborne, Dr Swaminathan said the virus can survive and be transmitted in the air, but in a very confined environment.

Dr. Soumya Swaminathan, chief scientist of WHO, explained the reason behind this

He said that when we speak, shout, sing, or even breathe, many droplets come out of our mouths, and these droplets have different sizes. Large drops fall to the ground within 1-2 meters. This is why there is so much emphasis on maintaining social distancing to avoid transferring these droplets directly from person to person.

“But there are also small droplets smaller than 5 microns. They are called aerosols and because they are smaller, they can stay in the air for a while because they take a bit longer to fall to the ground.” Dr. Swaminathan said, “Drops can be moved by gusts of wind etc. These particles float in the air for some time and when a person breathes they can become infected with this dangerous virus.

While he said this form of airborne transmission is very different, he believes two types of airborne transmission can occur. He explained about these tiny droplets and said that because they are very small, they can stay in the air for 10-15 minutes after coming out of someone’s mouth. , you can get infected, because small droplets with the virus are still floating in the air. sky.

He said that if it had aired, the number of people infected would have been higher by now. Further said Dr. Swaminathan that if we keep a proper distance from a person it will be a little easier to stop it.

WHO said it has evidence of airborne spread of Covid-19

On Tuesday, the WHO acknowledged that there are indications of the spread of Covid-19 in the air. Maria Van Kerkhove, WHO’s technical lead on the COVID-19 pandemic, said: “We are talking about the possibility of airborne transmission and aerosol transmission as one of the modes of transmission of COVID-19.

The WHO has previously stated that the virus is respiratory and spreads mainly through small droplets from the nose and mouth of an infected person that do not quickly fall to the ground.

This virus spreads through the air, but can be transmitted especially in situations with many people, little space and dirt, from where it can spread quickly.

Strengthening the immune system to fight COVID-19 helps fight this virus. Dr. Swaminathan said it is very difficult and most of the world’s population is still fighting with COVID-19 and trying to beat it as well. But it can also happen that we take a very long time.
