To achieve UNAIDS 90:90:90 targets at population-level, knowledge of HIV status must be followed by timely linkage to care, initiation and maintenance antiretroviral therapy (ART) for all people living with (PLHIV). Interpreting quantitative patterns using qualitative data, we investigate time taken link care initiate ART amongst individuals aware their HIV-status in high HIV-prevalence urban communities the HPTN 071 (PopART) study, a community-randomised trial combination prevention...

Moxifloxacin (MFX) and linezolid (LZD) are key components of rifampicin-resistant TB treatment regimens. Currently, available dispersible tablet formulations both drugs have poor palatability in children. We evaluated children's preferences for more child-friendly from two generic manufacturers.

Current antiretroviral therapy (ART) adherence monitoring is premised on patients' self-reported behaviour (prone to recall error) and verified by blood viral load measurement (which can delay results).
