Gender-based violence (GBV) is widespread globally and has myriad adverse health effects but is vastly underreported. Few studies address the extent of reporting bias in existing estimates. We provide bounds for underestimation of reporting of GBV to formal and informal sources conditional on having experienced GBV and characterize differences between women who report and those who do not. We a...

Cases (N 1⁄4 658) and controls (N 1⁄4 1,316) were individually matched by age, sex, race/ethnicity, timing of stud...

INTRODUCTION Persistent infection with GBV-C (GB Virus C), a non-pathogenic virus related to hepatitis C virus (HCV), prolongs survival in HIV infection. Two GBV-C proteins, NS5A and E2, have been shown previously to inhibit HIV replication in vitro. We investigated whether the GBV-C NS3 serine protease affects HIV replication. RESULTS GBV-C NS3 protease expressed in a human CD4+ T lymphocyte...
