Not the exact data you’re looking for, but hopefully somewhat informative - here’s my post from another thread on COVID-19 infection fatality rate: > [@Current estimates of COVID-19 Mortality Rates?](https://boards.straightdope.com/t/current-estimates-of-covid-19-mortality-rates/921433/5): > > Here’s the CDC’s current best estimate of the infection fatality rate (deaths/total infections): [COVID-19 Pandemic Planning Scenarios | CDC](https://www.cdc.gov/coronavirus/2019-ncov/hcp/planning-scenarios.html) (see Table 1 about halfway down the page, “Scenario 5” column) 0-19 years: 0.0003% 20-49 years: 0.02% 50-69 years: 0.5% 70+ years: 5.4% Here is a Swiss study with similar numbers: [https://osf.io/wdbpe/](https://osf.io/wdbpe/) 5-9 years: 0.0016% 10-19 years: 0.00032% 20-49 years: 0.0092% 50-64 years: 0.14% 65+ years: 5.6% All: 0.64% A meta-analysis of IFR studies from… From the meta-analysis of IFR from around the world: (IFR, meaning percentage of infected people who have died) Under 55 years: “Close to zero” 55-64 years: 0.4% 65-74 years: 1.3% 75-84 years: 4.5% 85+ years: 25% 75% of the 85+ year old group survive. How many of that 75% require medical treatment, I don’t know/haven’t found data on. Also, what’s your definition of “mild?” I’ve learned that a “mild” case of disease in medical terms generally means “not in the ICU,” which isn’t how most people think of the word. --- _[View the full topic](https://boards.straightdope.com/t/how-many-elderly-covid-patients-get-mild-cases/925445)._
