USA Winter 2021 CoVID-19 Resurgence Post-Christmas Update

We have successfully modeled every USA CoVID-19 wave using: where N ( t ) is the total number of new CoVID-19 cases above a prior baseline, and t R sets the doubling time t dbl = t R (ln 2). The new parameters { α S ; δ o } measure mitigation efforts among the uninfected population , with { α S > 0} being associated with Social Distancing and vaccinations ; while { δ o > 0 }is associated with mask-wearing , which gives a faster post-peak drop-off . The predicted pandemic wave end is when N ( t ) no longer increases. Using data from 11/15/21-12/30/21, our prior medrxiv . org preprint* showed this initial Omicron CoVID-19 wave had values that matched the initial stage of the prior USA Winter 2020 resurgence { t R ≈8 05 days ; α S ≈ 0 011 / day }, when practically no one was vaccinated. In addition, this initial Winter 2021 wave showed virtually no mask-wearing { δ o ≈ × 0 001 10 −3 / day }, making it capable of infecting virtually everyone. These parameter values indicated that the Omicron variant was likely evading the vaccines in people who thought they were protected. As a result, stopping the Omicron CoVID-19 spread must once again rely on enhanced Social Distancing and mask-wearing , just like the initial pandemic wave in March 2020. Analyzing the USA follow-on data from 12/25/21-1/31/22 shows that people did exactly that after the Christmas Holiday season, resulting in the following model parameters and values: for this wave by itself, with all prior waves subtracted out as a baseline. Combining all the USA CoVID-19 waves gives these updated totals: assuming no future CoVID-19 Resurgence ( with 4 Figures ). *(10 . 1101_2021 . 10 . 15 . 21265078)
