This is a good report, thanks for sharing. Though would be more informative to also share raw data tables for all the charts.
I dug a bit to double-check the hospitalization rate. The Oct 28 report claims (page 7) "18 Times higher risk of being hospitalized with COVID-19". That's a pretty spectacular number, how did they derive it?
1. The report says "One hundred ninety-one patients are currently hospitalized with laboratory-confirmed COVID-19; of these, 134 (70.2%) are not fully vaccinated.".
2. I found the vaccination rate as 67%, using the dashboard at https://data.ct.gov/stories/s/CoVP-COVID-Vaccine-Distributio....
3. I do a little bit of math.
pop_rate = pop_cases / pop_count
pop_cases = pop_case_rate * cases_total
pop_count = pop_count_rate * pop_total
risk = unvax_rate / vax_rate
= (unvax_rate / unvax_count_rate) / (vax_rate / vax_count_rate)
= (70.2 / 33) / (29.8 / 67)
= 4.8x
Your number (5x) is close to what the data indicates compared with what the report claims (18x). Perhaps someone with better fifth grade math skills can riddle me out...
