OBJECTIVE: A resurgence in bacterial STIs, notably syphilis, among gay, bisexual and other men who have sex with men (MSM) has been detected in England. A Canadian modelling study postulated that antiretroviral therapy (ART) may...

HIV spread in men who have sex with men (MSM) is an increasing problem in Poland. Despite the existence of a surveillance system, there is no direct evidence to allow estimation of HIV prevalence and the proportion undiagnosed...

INTRODUCTION: The HIV epidemic in England is largely concentrated among heterosexuals who are predominately black African and men who have sex with men (MSM). We present for the first time trends in annual HIV incidence for...
