There's some alarming stuff: Among 55,924 laboratory confirmed cases reported as of 20 February 2020, the median age is 51 years (range 2 days-100 years old; IQR 39-63 years old) with the majority of cases (77.8%) aged between 30–69 years. Among reported cases, 51.1% are male, 77.0% are from Hubei and 21.6% are farmers or laborers by occupation. So that's a large sample size. Here's what they found: Approximately 80% of laboratory confirmed patients have had mild to moderate disease, which includes non-pneumonia and pneumonia cases, 13.8% have severe disease (dyspnea, respiratory frequency ≥30/minute, blood oxygen saturation ≤93%, PaO2/FiO2 ratio <300, and/or lung infiltrates >50% of the lung field within 24-48 hours) and 6.1% are critical (respiratory failure, septic shock, and/or multiple organ dysfunction/failure). If that is true, it's going to put a huge strain on our medical resources. If this thing infects 10 million Americans (the flu infects about 30 million every year), 600,000 will be in intensive care, at least for a little while. That's a little less than all the staffed hospital beds in America. In China, the overall CFR (crude fatality rate) was higher in the early stages of the outbreak (17.3% for cases with symptom onset from 1- 10 January) and has reduced over time to 0.7% for patients with symptom onset after 1 February (Figure 4). That's in line with what we're seeing from the Diamond Princess: a mortality rate of just about 1%. The other stuff in the report is about China's response. https://www.who.int/docs/default-so...na-joint-mission-on-covid-19-final-report.pdf
