Individuals from all populations and age groups who are infected with HIV should begin antiretroviral treatment (ART) immediately after diagnosis, regardless of CD4 cell count, according to updated treatment and prevention recommendations for HIV issued in September by the World Health Organization (WHO) (http://bit.ly/1j0saZW). This guideline is based in part on evidence from clinical trials released since 2013 that suggest earlier initiation of ART among patients with HIV improves survival, reduces morbidity, and lowers the risk of transmitting the virus to uninfected individuals.
