1. 4、During the medical observation, what symptoms of close contacts need to seek medical attention?

During the medical observation, once the close contact has any symptoms (including fever, chills, dry cough, productive cough, nasal congestion, runny nose, sore throat, headache, fatigue, muscle aches, joint pain, shortness of breath, dyspnea, chest tightness, conjunctival congestion, nausea and vomiting, diarrhea, abdominal pain, etc.), it should be immediately reported to the local health department. According to the regulations, diagnosis and treatment are required in the designated hospitals, and the sampling should be collected for laboratory screening tests. If the result of the screening test suggested it is a suspected case or a confirmed case, medical observation should be performed on those who are in close contact with the case.

2. 5、Why should close contacts be observed for 14 days?

The isolation period of an infectious disease is determined based on the incubation period of the disease. The incubation period refers to the period from the invasion of the pathogen to the clinical symptoms. The incubation period of COVID-19 is 1-14 days, mostly 3-7 days, and it is contagious during the incubation period. Considering the incubation period of diseases caused by other coronaviruses, the relevant information of the 2019-nCoV infection cases, and the current prevention and control efforts, the medical observation period for close contacts is set to 14 days.
