Drivers of onward HIV transmission risk among adolescent boys growing up with HIV: a longitudinal cohort study.

ABSTRACT:

Introduction

HIV transmission to sexual partners is determined jointly by viraemia and condomless sex, both of which are higher among adolescents living with HIV compared with adults.
