Headache is not a symptom of novel coronavirus pneumonia. Novel coronavirus infection pneumonia is mainly manifested by fever, malaise, and dry cough, with a few patients having nasal congestion, runny nose, and diarrhea. Severe patients develop respiratory distress a week after the onset of the disease, and severe cases progress to acute respiratory distress syndrome, septic shock, uncorrectable metabolic acidosis and bleeding and coagulation dysfunction. Mildly ill patients present with low-grade fever and mild malaise, and most of those without pneumonia manifestations recover after one week.
