Where can I find conditions that have been shown to increase the risk of severe COVID-19 illness?

The list of underlying health conditions and other factors shown to increase the risk of severe COVID-19 illness is long. Advanced age remains the strongest risk factor. CDC provides a list of at-risk conditions at this website: www.cdc.gov/covid/hcp/clinical-care/underlying-conditions.html. The conditions are stratified by strength of published evidence.

Immunize.org provides age-appropriate standing orders templates for COVID-19 vaccination on the COVID-19 main page: www.immunize.org/vaccines/a-z/covid-19/. These templates include the broad, general list of conditions that increase the risk of severe COVID-19 found at www.cdc.gov/covid/risk-factors/index.html.
