From Gatherings to Coffees, How Coronavirus Spreads in Our Three Daily Situations

El Pais published an interesting summary of the likelihood of infection in three daily scenarios based on the implementation of security measures and the length of exposure to infection.

Example 1 Six people gather in a house and one of them is infected. About 31 percent of the coronavirus infections reported in Spain are caused by this kind of collection.

Even if they keep a safe distance, five out of six will be infected after four hours of dating. Clearly, people in this scenario aren't wearing masks and talking loud, and there's no ventilation in the room.

If they wear facial masks, four people risk infection. However, masks will not prevent infection if they extend exposure to the virus.

The risk of infection is minimized when the group uses masks, halves meeting time and airs space, transmits Balkanweb.

Coronavirus spreads through the air, especially in closed environments. Although the virus is not so contagious that, for example, measles, scientists are now talking about the important role of aerosol transmission that a infected person takes out and then stays in the air.

How does the aerosol transfer work and how do we stop it?

Experts currently have knowledge of the three ways coronavirus is transmitted. These are small dots that arise when they speak or cough (they may end up in the eye, mouth, or nose of people who stay nearby), contaminated surfaces and aerosol.

As far as transmission through polluted surfaces, American Centers for Disease Control and Prevention (CDC) say it is the least possible way of infection, and the European Center for Disease Control and Prevention (ECDC) says no case of disease has been observed.

Space - free airships remain floating in the air and become denser over time.

At the beginning of the pandemic, it was believed that the large points we expel when coughing or sneezing are the main ones responsible for the transmission of the coronavirus. However, we now know that shouting and singing in closed spaces, poorly ventilated also increases the risk of infection. Because loud speech releases 50 times more infectious particles than when we don't talk at all.

Aerosol concentration, if the room is not ventilated, gets higher, which increases the risk of infection. Scientists have discovered that aerosols can infect people who spend more than a few minutes within a five - foot radius of an infected person. Of course, infection is also affected by the length and nature of self - interaction.

Health authorities at the beginning of the epidemic did not focus on the transmission of coronavirus by aerosols, but the situation has changed.

Coffee or restaurant

Coronavirus infection is common in the events in cafes or restaurants. Moreover, each presentation of the virus in a nightclub infects an average of 27 people.

Such a situation occurred at a club in the Spanish town of Cordoba, in the south of the country, where, after a night abroad, up to 73 people resulted in positive coronavirus.

Scientists also recently analyzed the coronavirus show at a local in Vietnam, where 12 people were infected.
