The main prevention of novel coronavirus infection should be vaccination, or good personal protection, including wearing masks and disposable gloves. Patients with novel coronavirus pneumonia or asymptomatic infections can transmit the virus to others in the form of droplets and aerosols, or through indirect contact by attaching the virus to the surface of objects. When in contact with a patient with novel coronavirus pneumonia, it is important to keep a certain distance, wear a protective medical mask, disposable gloves, and protective isolation clothing. Vaccination can provide prevention, but the duration of prevention is uncertain. Novel coronavirus pneumonia is characterized by fever, malaise, dry cough, and gradual onset of respiratory distress.
