How do I know if I am infected with novel coronavirus, or if there is an incubation period?

The diagnosis of novel coronavirus needs to be tested by nucleic acid detection kit, and the positive result of nucleic acid detection means that the diagnosis sometimes needs multiple tests.

The common symptoms of novel coronavirus are fever, fatigue, dry cough and gradual dyspnea. Some patients have mild symptoms, but no fever. Severe cases are acute respiratory distress syndrome, septic shock and coagulation dysfunction caused by metabolic acidosis that is difficult to correct. Most patients have mild illness and good prognosis, and a few patients are in critical condition or even die. Patients can judge according to the above symptoms.

Referring to the incubation period of diseases caused by other coronaviruses, the relevant information of this case in novel coronavirus and the current prevention and control practice, the medical observation period of close contacts is limited to 14 days, and close contacts are observed at home.

However, if diagnosis is needed, the nucleic acid detection kit needs to be tested. Taking Hefei as an example, samples collected by primary disease prevention and control institutions will be tested in the inspection center of Hefei CDC to determine whether patients are infected with novel coronavirus. In the laboratory, the inspector must be "armed to the teeth" to start the inspection.

The staff will test each sample for nucleic acid, and if the result is positive, it will be reported to the provincial CDC. The provincial CDC review, the result is still positive, issued by the provincial health and health commission.
