After diagnosis of the new coronavirus, isolation, treatment and regular review are required. 1. Isolation: The new coronavirus has strong transmission ability, mainly through the respiratory tract, and is easy to cause widespread infection, so patients need to go to a designated hospital for isolation and treatment immediately after diagnosis. 2. Treatment: There is no specific drug for new coronavirus pneumonia, and symptomatic treatment, supportive treatment and general treatment are the mainstays. Some patients need antiviral drugs such as lopinavir, and antibiotics such as cephalosporins if combined with bacterial infection. For patients with severe respiratory distress or hypoxemia, endotracheal intubation and respiratory support techniques are needed. General treatment such as bed rest, drink more hot water. 3. Regular checkups: Both mild and severe cases of CKP require regular checkups of nucleic acids and temperature, as well as CT of the lungs if necessary. If there is a history of close contact and related symptoms, it is recommended to isolate and actively seek medical attention.
