High prevalence of advanced HIV disease in Sub-Saharan Africa: an analysis of 11 household surveys
The study analysed the advanced HIV disease (AHD) prevalence across sub-Saharan Africa by pooling all PHIA surveys with available CD4 cell count data and found a prevalence of 10% with large variation across the treatment cascade in countries. The study also found a higher AHD prevalence in men than in women and estimate that 1.9 million adults with HIV in sub-Saharan Africa have AHD and that 44% of these people have suppressed/undetectable viral load.

Vaccine effectiveness against COVID in-hospital mortality by HIV status across SARS-COV-2 variants
The study analysed the impact of COVID-19 vaccine in reducing in-hospital mortality among people living with HIV (PLHIV). The risk of death remained relatively high among PLHIV compared with the HIV negative groups. These findings highlight the need to implement WHO guidelines recommending booster vaccine for populations most-at-risk of severe COVID-19 outcomes including PLHIV.
