Is there a high chance of being infected with Omicron when eating in the same space?

It's huge. Generally speaking, the infection rate of close contacts of Omicron mutants is relatively high, but there is no data to show the specific infection rate of close contacts of Omicron mutants. It is suggested that the close contacts of Omicron mutant should have regular nucleic acid tests to determine whether they are infected or not, and should be isolated to avoid infecting others during the incubation period.

Omicron mutant is a novel coronavirus mutant. Generally speaking, people who have had direct contact with patients infected by Omicron mutants are called close contacts of Omicron mutants. Because Omicron variants are highly contagious and can spread rapidly among people, the infection rate of close contacts of Omicron variants is usually higher, but the infection rate of different people may be different.

For healthy adults, because of their relatively strong immunity, the probability of being infected will decrease. If people who have been vaccinated with novel coronavirus vaccine have certain antibodies in their bodies, the probability of being infected will also be reduced. However, if they are elderly people, their immunity is usually relatively weak and they are relatively easy to be infected with Omicron variants. If people who have not been vaccinated with novel coronavirus vaccine do not have antibodies against novel coronavirus, the probability of infection is usually higher.
