Scientists have identified the main source of the spread of coronavirus
A group of American scientists have come to the conclusion that coronavirus multiplies most easily in the mouth. According to them, the oral cavity is one of the most favorable places for the emergence of a COVID-19 outbreak.
As noted in an article published on the portal medRxiv, the risk of infection through the mouth may be underestimated - the chances of infection through saliva or due to the virus entering directly into the lungs increase.
Scientists point out the need to wear masks. According to the researchers, these remedies are most effective at preventing the spread of coronavirus through the mouth. It is when coughing or talking that the risk of transmission of the virus from one person to another increases.
