The sections on masks and policy conclusions in the facts section (below) were revised 8/4/20. Unexpected deaths data from the CDC was updated 8/6/20.
Source: The Covid Tracking Project (https://covidtracking.com/data/state/oklahoma), which assembles data daily from the Oklahoma Department of Health (OKDOH). OKDOH does not provide longitudinal data.
* Tests that show positive for the SARS-CoV-2 virus identify cases where there are symptoms (Covid-19), but also detect mere fragments of the virus after a mildly symptomatic infected person's immune system has killed the virus. The Oklahoma Department of Health counts anyone who tests positive as a Covid-19 case. This number includes people who do not have the disease (are asymptomatic). See explanations here and here.
NOTE: OKDOH reported incorrect totals for 7/19-7/21. Correct 7/21 and 7/22 daily numbers are reported here and here. Numbers for 7/19 and 7/20 are adjusted to reduce bias in the 7-day average. Overall totals are correct.
NOTE: There is some anecdotal evidence that the number of deaths is exaggerated.
The Centers for Disease Control produces a model of how many deaths each state might expect (weekly since Januray 2017), in the chart above from all causes given time of year and demographics. A "+" character indicates weeks with more deaths than expected compared to the upper end of a 95% confidence interval. The chart indicates that, so far in Oklahoma, flu in January 2018 was more deadly than Covid-19 by this measure. https://www.cdc.gov/nchs/nvss/vsrr/covid19/excess_deaths.htm
