Pretty high % of severe cases needed ICU in @TheLancet study on #COVID19 mild/severe: 📌61% mild, 39% severe. 📌Of the severe cases, 77% needed ICU. (79 Cases from Nanchang China, Jiangxi Provide; ie not Hubei). thelancet.com/journals/lanin…

Erratum: 76 cases not 79. Apologies for the mental copy paste slip.

2) “The mean viral load of severe cases was around 60 times higher than that of mild cases, suggesting that higher viral loads might be associated with severe clinical outcomes”. #COVID19

3) “Mild cases were found to have an early viral clearance, with 90% of these patients repeatedly testing negative on RT-PCR by day 10 post-onset. By contrast, all severe cases still tested positive at or beyond day 10 post-onset.” #COVID19

4) “Overall, data indicate that, similar to SARS in 2002–03,6 patients with severe #COVID19 tend to have a high viral load and a long virus-shedding period. finding suggests that the viral load of #SARSCoV2 might be a useful marker for assessing disease severity and prognosis”

5) Demographics or the cases. More men than women again. But hard to say if by chance with limited cases. Interesting that coughing was only see in roughly 1 in 2 cases. #COVID19
