WHO urges CD4 testing to detect advanced HIV cases early

WHO emphasised CD4 testing to detect advanced HIV, defined as CD4 count below 200/mm in adults, adolescents, and children over five. Early identification helps manage severe cases, guide prophylaxis, and improve treatment outcomes. CD4 testing is crucial where viral load testing is unavailable, supporting timely ART initiation, better care, and reducing HIV-related deaths globally.
