Covid-19 August 17, 2021

Fig 1 

• Indicates the confirmed COVID-19 daily cases noticeably started to increase around the 3rd week in June 2021.
• At this time the delta variant was about 50%
• By August 17, 2021, the leading states in terms of daily cases were Louisianna,  Mississippi, Florida, Arkansas, Alabama, and South Carolina  

Fig 2 shows the ratio of deaths/confirmed cases, it is seen that

• As the % deltas variant passed 60%  there is a noticeable decrease in the ratio, more specifically by 8/16/2021 for :
  • Hawaii decreased by -22.5%, Louisianna -18.3%, Michigan -12.6%, Oklahoma -8.7%, Michigan -8.28%, and South Carolina by -7.93%.
  • On the other hand, Maine increased by 2.46%, Wisconsin by 0.85%, Michigan by 0.49%, and Montana, South Dakota, Utah, and Minnesota had a 0% change.
  • The average change in the ratio was  4.71% +-  4.6

Thus there is evidence that the delta variant does not kill as large a proportion of those it infects as do the previous variants. 

Fig 3 shows the daily confirmed cases on 8/19/2021 vs % population vaccinated for the US states.  With the exception of Florida it is seen that the states (Mississippi, Lousiana, Alabama, and Arkansas) with the lower % of people fully vaccinated have the higher confirmed cases.
