Table. Levels of immunocompromise in children and adults with HIV

Also consider other factors such as concurrent medical conditions or medications when assessing levels of immunocompromise in children and adults with HIV.

Level of immunocompromise	Infants aged <12 months, CD4⁺ count	Children aged 1–5 years, CD4⁺ count	Adults and children aged ≥6 years, CD4⁺ count
Not immunocompromised	≥1500 cells/μL	≥1000 cells/μL	≥500 cells/μL
Moderately immunocompromised	750–1499 cells/μL	500–999 cells/μL	200–499 cells/μL
Severely immunocompromised	<750 cells/μL	<500 cells/μL	<200 cells/μL
