People who are at higher risk for severe illness

COVID-19 is a new disease and there is limited information regarding risk factors for severe disease. Based on currently available information and clinical expertise, older adults and people of any age who have serious underlying medical conditions might be at higher risk for severe illness from COVID-19.

Based upon available information to date, those at high-risk for severe illness from COVID-19 include:

People aged 65 years and older
People who live in a nursing home or long-term care facility
Other high-risk conditions could include:
- People with chronic lung disease or moderate to severe asthma
- People who have heart disease with complications
- People who are immunocompromised including cancer treatment
- People of any age with severe obesity (body mass index [(BM]I)≥40) or certain underlying medical conditions, particularly if not well controlled, such as those with diabetes, renal failure, or liver disease might also be at risk
People who are pregnant should be monitored since they are known to be at risk with severe viral illness, however, to date data on COVID-19 has not shown increased risk

Many conditions can cause a person to be immunocompromised, including cancer treatment, bone marrow or organ transplantation, immune deficiencies, poorly controlled HIV or AIDS, and prolonged use of corticosteroids and other immune weakening medications
