An incubation period exists after infection with novel coronaviruses. The shortest known incubation period is 1 day, usually 3-7 days, and the longest is 24 days. Patients in the incubation period are also contagious, so if you have been in contact with such patients yourself, you should avoid going out and self-isolate as much as possible.
Be diligent in ventilation at home, wash your hands frequently, exercise more to strengthen your immune system, and pay close attention to your health. If you have symptoms such as fever, malaise, dry cough or severe breathing, you should immediately go to a hospital fever clinic or infection department for examination to clarify whether you are infected with novel coronavirus.
