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. In addition to age, CDC states that data has shown that compared to non-Hispanic White people, people from racial and ethnic minority groups are more likely to be infected with SARS-CoV-2. Once infected, people from racial and ethnic minority groups are more likely to be hospitalized, be admitted to the ICU, and die from COVID-19 at younger ages. 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 an age-appropriate list of high-risk conditions with conclusive or suggestive published evidence as part of each of its standing orders templates for use of 2025-2026 COVID-19 vaccines, all of which may be found on the COVID-19 main page: www.immunize.org/vaccines/a-z/covid-19/.
