This review examines the intersection of the HIV and SARS-CoV-2 pandemics. People with
HIV (PWH) are a heterogeneous group that differ in their degree of immune suppression …

SARS-CoV-2 subvariants BQ. 1.1 and XBB. 1 have been circulating globally with superior
growth advantages over most omicron mutants (appendix p 5). However, XBB. 1.5, a …
