Prevention of anogenital cancers in women may be an additional benefit of HPV vaccination

Cervical cancer is evidently the most important, but by no means the only, health risk that vaccination against HPV aims to avert. The potential impact of vaccination on other cancers (not to mention genital warts) may also be a factor in estimating the cost benefit of achieving higher vaccination coverage, as well as determining priorities […]

Living dangerously in the Dominican Republic and Mexico City: can cash transfer payments be used to counteract the “risk premium”?

The Caribbean has the highest levels of HIV outside sub-Saharan Africa – and the Dominican Republic (DR), which together with Haiti accounts for 70% of all people living with HIV in the Caribbean region, is a hotspot.  While there has been a 73% reduction in the rate of new infections in the DR between 2001 […]

Tracking the origin, early spread, and ignition of pandemic #HIV-1 through new approaches to phylogenetic analysis

“Distribution of HIV-1 subtypes in a population”, state Mumtaz & Raddad (STI) in a study of the HIV pandemic in the Middle East, “tracks the spread and evolution of the epidemic”.  Various studies covered in our previous blogs have attempted to read the history of the progress of the HIV epidemic through the evidence of […]

“Hispanic” label masks the specificity of the Puerto Rican #HIV problem in US Northeast

Interventions for HIV prevention should be informed by an understanding of the long-term source of infection, and not just by recent distribution (Mishra & Boily (STIs)).  Amongst recent studies that have sought to inform future interventions are investigations of known subgroups thought to be a potential bridge into the wider population – such as migrant […]
