For most children with HIV and low immune cell count, cells rebound after treatment

A new study published in the journal AIDS found that for most children with HIV and low immune cell counts, cells rebound after treatment. The researchers analyzed data from over 3,700 children infected with HIV before or during birth and found that 86% of children achieved normal CD4+ counts within one year of treatment.
