COVID deaths after 17 Jan 2022 can be ascribed to the Omicron variant, because Omicron had reached to over 90% of all circulating COVID before even 10 Jan 2022.
The plausible limits of lethality for Omicron variant include an infection fatality rate (IFR) of about 0.03% up to a maximum plausible IFR of 0.064% — equivalent to 1 death per 1562 infections.
IFR values for Omicron which are higher than 0.064% are not consistent with the observed death data. An IFR of 0.064% was the upper bound on a 99% credible interval for Omicron based on just 12 deaths from over 37,000 Omicron infections in Ontario.
Here are 13 states with up-to-date accumulated deaths from Worldometers along with the deaths which had accumulated up to 17 Jan 2022. Deaths after 17 Jan 2022 can be ascribed to Omicron, as noted above.
But this implies a certain number of infections, because at 99% confidence, it takes at least 1562 Omicron infections in order to produce one death.
As you can see from above, if public officials in Ohio are to be believed — if we are going to believe it when they says that 6444 COVID deaths occurred after 17 Jan 2022 — then that implies an attack rate of 86%.
The only way for COVID to be able to kill 6444 Ohio-ans is if COVID infected 86% of the population of Ohio in less than 3 months time. But here are the positivity rates for Ohio, and they do not match up with the known lethality of Omicron.
The top graph in red represents COVID death in Ohio, while the bottom graph in blue represents COVID positivity rates. While peak positivity reached 33% when peak death reached 157 deaths (see markings), there was never an indication that 86% of Ohio developed COVID in under 3 months.
The disturbing conclusion is that public health officials in Ohio are actually lying when they report COVID deaths, because Omicron variant is not lethal enough to lead to the recent COVID deaths reported in Ohio.
