About half of the patients developed dyspnea after one week, and severe cases quickly progressed to acute respiratory distress syndrome, septic shock, refractory metabolic acidosis and coagulation dysfunction. It is worth noting that severe and critically ill patients may have moderate to low fever or even no obvious fever. Some patients have mild onset symptoms, but no fever, and most of them recover after 1 week. Most patients have a good prognosis, and a few patients are critically ill or even die.
