New information is emerging about how the coronavirus is infected and who is most at risk.

According to doctors, like other infections, certain people are more or less likely to be infected with the coronavirus based on many factors and are beginning to narrow down who their group is.
COVID-19 can also be transmitted in the air and on the ground, but Dr. Ameshua Dalha of the Johns Hopkins Health and Security Center says it is much less likely.
“The main way people get infected with COVID-19 is to have close personal contact within 6 feet with another individual who has the virus,” Adalja said.
Close personal contact for more than 10 minutes is the way most people get COVID-19. However, researchers have found that only a quarter of people living in the same household as COVID-19 patients are infected because of low exposure or T cell immunity.
“Because there are four other coronaviruses that cause about 25% of our common cold, that T cell immunity can occur, and some of that T cell immunity can be cross-reactive. There is, “says Adalja.
There is also some evidence that blood types play a role in getting sick. Adalja is not definitive, Researchers have found that people with ABO blood group are less likely to be infected with COVID-19 or may be severely ill...
“We know that the immune system is involved in a complex blood group. If you have type O blood, you can play a role in how the virus interacts with your blood group. Having an antibody against type B, there may be some differences. Receptors that must bind. “
Researchers are also investigating the amount of virus, or the number of viral particles that enter the body, and how it affects the severity of the case. In general, the higher the viral load, the more severely a person can be transmitted to others. Therefore, it is especially important to wear a mask.
“If you’re infected even though you’re covering your face, you’re probably getting less viral because some of those particles are blocked,” Adalja said.
But the advice is the same for everyone, regardless of blood type or viral load. Wear a mask, wash your hands and keep a social distance, especially indoors.
“The main thing we really need to worry about is people who are in close contact with each other where one of them may be infected with the virus,” Adalja said.
