CD4 and coinfection: This study found that HBV infection prevalence among HIV infected patients in a busy hospital clinic in Northern Uganda was 7.9%, and identified three independent factors associated with co-infection: living in an IDP camp between 1989 and 2006 [9, 24], cohabitation with HBV-infected persons during childhood, and a poorer CD4+ T cell count response to ART that underscores the negative impact of chronic HBV infection on HIV immunological response [20].
