Patients who have been in contact with patients with novel coronavirus infection must isolate themselves for 14 days without protective clothing, goggles and medical surgical masks at the time of contact, and separate from family members. During the isolation period, body temperature should be monitored daily, no contact with outsiders should be made, and community workers should be reported promptly. If symptoms such as fever, cough or malaise occur during the 14-day isolation period, be sure to seek immediate hospital care. Protective isolation should be done when escorting to prevent the spread of the virus. After arriving at the fever clinic of the hospital, you should inform the doctor of the relevant conditions and actively cooperate with the doctor to carry out relevant examinations and isolation treatment in order to effectively minimize the spread of the virus. If the patient remains symptom-free after 14 days of isolation, the isolation can be lifted.
