About how someone, while he can live in the same place with a positive person in the virus, is not infected, answered Dr. Petros Karagiannis.
There are many cases where people who while living in the same house and may not take the necessary protection when someone is found positive, still remain negative for the virus.
According to Mr. Karagiannis, this depends on the viral load left by a person.
If he coughs or sneezes, that is, he has developed symptoms, he transmits the virus much more easily than if a person is asymptomatic.
In addition, as the days go by and the infection progresses at the same time, the viral load drops and further removes the possibility of transmitting the virus.
One factor that seems to play a role in the transmission of the virus based on studies is the blood type.
People with blood type C are, on average, 12% less likely to be infected with coronavirus than other blood types.
Also, those with a negative blood type (O-, A-, B- or AB-) have a 21% lower risk of catching the coronavirus than those with a positive blood group, according to a new Canadian scientific study.
Also, people with blood type C are 13% and 19% less likely to develop severe symptoms of Covid-19 or die from the disease. Therefore, those with a negative blood type O- seem to have the lowest risk of all.
