What are the symptoms of novel coronavirus infection?

Novel coronavirus infection primarily manifests as fever, dry cough, and fatigue. A minority of patients may also experience nasal congestion, rhinorrhea, sore throat, myalgia, or diarrhea. Most severe cases develop dyspnea or hypoxemia approximately one week after symptom onset.

In severe cases, the disease may rapidly progress to acute respiratory distress syndrome (ARDS), septic shock, refractory metabolic acidosis, coagulopathy, and multi-organ failure. Notably, patients with severe or critical illness may exhibit only moderate or low-grade fever—or even no obvious fever—during the course of the disease. Mild cases may present solely with low-grade fever and mild fatigue, without evidence of pneumonia.

Most patients have a favorable prognosis; however, a small proportion develop critical illness. Elderly individuals and those with underlying chronic diseases tend to have poorer outcomes, whereas children typically exhibit milder symptoms. Wash hands frequently: use soap or hand sanitizer and rinse thoroughly with running water; dry hands using disposable paper towels or clean towels. Maintain a balanced diet, engage in moderate physical activity, adhere to regular sleep-wake cycles, and avoid excessive fatigue.

Keep indoor environments clean and well-ventilated. Open windows for ventilation at least three times daily, each session lasting 20–30 minutes. Reduce the frequency of ventilation when outdoor air quality is poor. Avoid close contact with individuals suffering from respiratory infections. We hope this information is helpful to you.
