Those who have been exposed to the suspected population but are currently asymptomatic are close contacts and should be placed under strict medical observation. Based on current epidemiological surveys, the incubation period of novel coronavirus is generally 3-7 days, with a maximum of 14 days. Therefore, such people should be placed under home medical observation for 14 days, and they also need to be observed for symptoms such as fever, malaise, dry cough, nasal congestion, runny nose, and diarrhea. If there are respiratory symptoms, fever, chills, malaise, diarrhea, conjunctival congestion, etc., you need to seek medical attention promptly for investigation. You need to wear a mask on the way to the doctor and should not take public transportation or walk to avoid infecting others. Content source: Dr. You Lai
