The 95% confidence interval of total averagein 18 deaths (21%) was between 5 to 6 days. ARDS,kidney failure, and shock occurred within 4 days, en-cephalopathy within 6 days (average 4.8±0.9 days),abscesses after 14 days, systemic bacterial infectionand fungous infection within half a month (average14.6±1.1days, 14.8±0.9days respectively), and deathwithin 6 days.Conclusion: According to the time of the occurrence ofcomplications, we divide the courses of the disease intothree stages: early phase(first 4 days) with ARDS,kidney failure, shock, encephalopathy and hemorrhageof the digestive tract; middle phase (5-15 days) withbacterial infection and fungous infection; late phase(15 days after the onset) with abscess.展开更多
