Novel coronavirus nucleic acid positivity suggests infection with a novel coronavirus. Novel Coronavirus Pneumonia is an acute contagious pneumonia that can be spread by respiratory droplets, contact, and aerosols. Common symptoms include fever, dry cough, and malaise. A few patients are characterized by nasal congestion, runny nose, sore throat, decreased sense of smell and taste, etc. Severe patients tend to develop respiratory distress or hypoxemia one week after the onset of illness. The incubation period of neocoronavirus pneumonia ranges from 1 to 14 days, mostly from 3 to 7 days. Laboratory tests for novel coronavirus pneumonia include blood tests, examination of respiratory secretions, and imaging tests. A positive nucleic acid test for novel coronavirus suggests that the individual tested is infected with the novel coronavirus, and the patient may be symptomatic or asymptomatically infected. During the outbreak, if you develop symptoms such as fever and dry cough, please go to a local hospital with a fever clinic. Positive nucleic acid tests for the new coronavirus require centralized isolation.
