Therefore, when infected with this virus, patients and close contacts should be isolated immediately. When a person is infected with the novel coronavirus, a mild case may result in fever, dizziness, coughing, difficulty in breathing and other symptoms. If the condition is more serious, it may lead to damage to the patient’s lungs, heart, kidneys and other parts of the body, and cause the body to develop pneumonia, septicemia, acute respiratory distress syndrome, etc., and even threaten the patient’s life.
