      COVID-19 is an acute respiratory infectious disease. People are generally susceptible. Currently,the patients infected by the novel coronavirus are the main source of infection; asymptomatic infected people can also be an infectious source. Based on the current epidemiological investigation, the incubation period is 1 to 14 days, mostly 3 to 7 days. The main manifestations include fever, fatigue and dry cough. Nasal congestion, runny nose, sore throat, myalgia and diarrhea are found in a few cases.
      Nucleic acid detection of new coronavirus is based on pathogen detection, with high sensitivity and specificity. It is the best method to diagnose novel coronavirus infection. It can be found in the early stage of infection, so as to adopt medical isolation and treatment as soon as possible.
