How accurate is the individual number of covid-19 variant cases in each state?
I am trying to estimate the risk of being exposed to the one B.1.351 variant where the vaccine has been estimated to provide the least protection.
Currently (check the link for updates) the incidence of B.1.351 (The South African variant) cases is 1.0% of all new cases.
Update: Vaccine resistant South African Variant B.1.351 is doubling every month
The standard error of the proportion should provide a reliable estimate of the degree that the CDC numbers might be inaccurate. Current Genomic testing capacity is 9000 tests per week which is about 2% of the weekly case rate.
I just found this much better data It has the current proportion of B.1.351 (and other) variant cases: Variant Proportions in the U.S
It can be seen from the March 13 graph that the B.1.1.7 UK variant is dominant (59.6% of all recent cases).
