The results of the current epidemiological investigation of novel coronavirus infection show that the time between infection and onset of disease in most people is about 1-14 days, which is the clinical incubation period, and the time between infection and onset of disease and clinical diagnosis is about one day to two weeks, and most patients are 3-7 days. Recent clinical studies have found that some patients have a longer incubation period, some reaching more than 20 days, but such cases are very rare. The time from infection to onset of disease is about 3-7 days or 1 week. After patients are infected, the clinical manifestations are relatively mild in some patients in the early stage, but most patients, especially in severe cases, start to get worse at about 1 week. Most patients may have a relative change in their disease about a week after admission, and their disease may worsen. About 1 week to about 10 days after admission patients enter the recovery period, and lighter patients are discharged in about two weeks. Content source: Dr. You Lai
