Coronavirus Is NOT Transmitted By The Air

A very important message from the WHO: Coronavirus is not transmitted by air. How is it transmitted?

Coronavirus is not transmitted and does not spread through the air. The World Health Organization (WHO) published this conclusion on its official website on Sunday 29 March. In doing so, the WHO has denied one of the most common myths that one can be infected even by breathing in the same air as an infected person.

The WHO emphasizes that this statement should become an official response to the widely circulated claims in the media, and in particular in social networks, that if the patient is in the same room for an extended period, the virus can be transmitted from the sick person to the healthy person. In other words, if a healthy person were to appear in the area where the virus carrier was breathing, he or she could, even after a few hours, appear to be infected simply by inhaling “contaminated” air.

The WHO statement explains that the infection occurs by the direct transmission of tiny droplets in the respiratory tract (nose or mouth, breathing, sneezing or coughing) of a sick person. In addition, an infection occurs when a healthy person is close to the patient – about a meter away.

The organization has found that the virus-containing droplets are too heavy to hang in the air. They settle on surfaces, but they are not in the air. So if you walk where you were a few minutes or hours ago, it is impossible to get airborne.

The World Health Organization has reiterated that virus protection is provided by a social distance of at least 1 meter from the carrier of the virus, and that surfaces that may contain respiratory secretions or saliva of the sick person must be thoroughly washed or disinfected. means.

Recent studies published in the medical literature indicate that the coronavirus is able to persist on certain surfaces for hours to days. For example, copper surfaces – up to 4 hours, cardboard – up to 24 hours, plastic or stainless steel – up to 3 days. Similar results were obtained in the 2003 SARS study of coronavirus, an epidemic of atypical pneumonia.

And what about clothes? Laboratory studies in Hong Kong have shown that coronavirus does not survive on clothing at all (these tests are still under revision), and on paper it can take up to 24 hours.

How can a person become infected with COVID-2019?

Certain coronaviruses are transmitted from person to person, usually in close contact with the patient, such as at home or at work, in a medical facility. COVID-2019 can also be transmitted from person to person. The virus spreads through droplets of respiratory secretions that people secrete into the environment by sneezing, coughing or exhaling.

The incubation period (ie the period from infection to onset of symptoms) is 2 to 12 days. Although humans are usually contagious when symptoms occur, some carriers of the infection may transmit the virus before the onset of symptoms.
