The Omicron incubation period is contagious to others. The Omicron incubation period refers to the process from asymptomatic to clinical symptoms after a patient is infected with the Omicron strain. Depending on the patient’s physical condition and the speed of progression of the disease, the incubation period tends to be 3-7 days, with a maximum of about 14 days. Omicron belongs to a mutated strain, which is more transmissible than other common strains. Therefore, as soon as Omicron infection is identified, the patient has a certain ability to spread the disease, even if there are no obvious clinical symptoms during the incubation period. Therefore, in order to prevent infection by Omicron, it is not only necessary to receive the full course of vaccination with the New Crown vaccine, but also to take good personal protection by wearing a mask when going out, washing hands frequently, and paying attention to maintaining indoor ventilation.
