There are two ways For the transmission of the SK virusThe first is to touch the surfaces on which the virus is found, and the second is to inhale the drops caused by coughing or sneezing, but some experts said that there is a third way to transmit the Corona virus, which is the minute drops that a person issues while talking, according to what the channel reported NHK Japanese.

Kazeoho Tateda, president of the Japan Foundation for Infectious Diseases Control, said that the way the SKV is transmitted while talking to the infected person, even if there is a distance between you and him.

He added: We believe that the infection comes from fine particles that do not exceed a micrometer in size, and this method of transmission of the virus can be called “micro-droplet infection” or micro droplet infection. “

But how does infection occur in this way?

The researchers searched for microscopic drops using technological techniques that use highly sensitive cameras. This technology enables scientists to monitor droplets that are 1 micrometres in size and are equal to 1 / 10,000 Millimeter.

The experiment initially began with sneezing, as drops of droplets come out falling quickly, but when scientists looked at them with a high-sensitivity camera, they found glitter-like particles that flew into the air, the size of these drops up to 10 micrometers.

We thought sneezing was the only way to transmit these tiny drops, but when scientists conducted the same experiment on conversations between two people, they found that people emit many tiny drops when speaking loudly.

Kaziho said that the minute droplets that are released during speaking carry many viruses and we export these droplets when we speak loudly or breathe heavily while exhaling.

He added that the people around us inhale these drops, and from here viruses spread, including the Corona virus, and we are beginning to pay attention to this danger now.

For his part, Masashi Yamakawa, an assistant professor at the Kyoto Institute of Technology, said that the risk of infection with small drops becomes greater than the distances between us and others, adding that they had conducted experiments on 10 people in one closed room the size of a classroom, and when one person sneezed once and published about 100 A thousand drops were big blue green droplets that fell to the ground in a minute, but small micrometer droplets in red remained stuck in the air for 20 minutes after sneezing.

Masashi explained, if the air does not move or winds come, the drops remain in the air and will not move and can stay for a while.

One way to prevent these drops from transmitting the infection to others is to open windows to ventilate the place. When the window opens, tiny drops are washed away. They are small, light-sized drops that can fly into the air, and you can open windows twice every hour, this permanently reduces the risk of infection.
