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
