You may have seen this in the news today:
China Concealed Extent of Virus Outbreak, U.S. Intelligence Says - Bloomberg April 1
In particular, asymptomatic positives and deaths.
Not a huge surprise, and we already knew about some levels of inaccuracy, changes in reporting methodologies and so forth, but what does this do to estimations of R0
and what is the impact on other modeling factors that have been widely used in Europe and the US, with China as the benchmarking case?
It would be good to know if the asymptomatic positives have a different (weaker) strain of the virus and/or are less contagious themselves. There could be more than one R0
if there are, as some have reported, up to 5 different strains of the virus circulating right now.
Perhaps some less than 1 and perhaps some over 3, which brings us to the median of 2.x.
