Patients with fever do not necessarily go to the hospital right away because the fever may be caused by the flu, not necessarily by the novel coronavirus, and it is recommended that they be kept in isolation at home for 14 days. If the fever is caused by influenza, it will recover on its own in about a week. In the case of novel coronavirus infection, the incubation period is usually 3-7 days, with a maximum of 14 days. The main symptoms are fever, malaise, dry cough, and a few patients with nasal congestion, runny nose and diarrhea. Severe patients tend to develop respiratory distress after a week, and severe cases progress rapidly to acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis, and bleeding and clotting dysfunction. If the symptoms of fever persist and other abnormalities appear, seek immediate medical attention. Content source: Dr. You Lai
