Thanks, that's interesting. Given an infectiousness period, it seems you can relate R0 to doubling time. Like, if R0 is 2, that means each patient (on average)

Thanks, that's interesting. Given an infectiousness period, it seems you can relate R0 to doubling time. Like, if R0 is 2, that means each patient (on average) infects 2 others, but during the period of time they are infectious. So that would mean 2 others over the course of 10 days (8 days post-symptom, 2 days pre-symptom).

Someone else either in this video or one of the others they said viral shedding in COVID19 is a 1000 times higher than SARS. There is a paper up on the CDC website that estimated r0 between 3.8 and 8.7, which is much higher than initial estimates. Matches the observation that in crowded indoor locations (nursing homes, prisons, homeless shelters, cal centers) everyone becomes infected within days to a week. UCSF's grand rounds on covid19 go up every Thursday. Upside, high quality distilled information. Downside, hour and a half long.
