Established, probable, and possible risk factors (comorbidities that have been associated with severe COVID-19 in at least 1 meta-analysis or systematic review, in observational studies, or in case series):

Possible risk factors but evidence is mixed (comorbidities have been associated with severe COVID-19 in at least 1 meta-analysis or systematic review, but other studies had reached different conclusions):
|
CDC: Centers for Disease Control and Prevention; COVID-19: coronavirus disease 2019; COPD: chronic obstructive pulmonary disease; ADHD: attention deficit hyperactivity disorder; HIV: human immunodeficiency virus; BMI: body mass index.
* Listed comorbidities are associated with severe COVID-19 in all adults independent of age. People of color are also at increased risk of severe disease and death, often at a younger age, due to systemic health and social inequities.
¶ Risk of severe disease also rises steadily with age, with more than 93% of deaths occurring among adults ≥50 years and 74% of deaths occurring in adults ≥65 years.
Δ Underlying medical conditions are also associated with severe illness in children, but evidence implicating specific conditions is limited. Children with the following conditions might be at increased risk for severe illness: medical complexity; genetic, neurologic, or metabolic conditions; congenital heart disease; obesity; diabetes; asthma or other chronic lung disease; sickle cell disease; immunosuppression.Do you want to add Medilib to your home screen?
