Omicron is a new strain of Neocoronavirus, which causes Neocoronavirus pneumonia when infected with Omicron. According to the current epidemiological survey on this disease, there is a certain incubation period for novel coronavirus pneumonia, which is usually detected 1~14 days after infection with omicron, but in most cases it is 3~7 days. Since each patient’s physical condition is different, there is obvious individual variability regarding how many days after infection with Omicron can be detected positive, and no generalization can be made. Generally, there are no obvious symptoms in the pre-infection period, but some patients may have fever, dry cough, fatigue, weakness, nasal congestion, muscle pain, sore throat, loss of smell and other symptoms. In summary, if you suspect that you are infected with Omicron, you need to go to the hospital in time to complete a series of related examinations.
