Globally, there are an estimated 15.6 million people who inject drugs (PWID).1 Among PWID, the risk of acquiring HIV is more than 30 times higher than the rest of the population.2 However, HIV incidence has declined among PWID in Western Europe over the last two decades. In light of this improved situation, a 2023 study investigated changes in HIV incidence in Ireland among PWID from 2000 to 2018.2
In this study, published in the journal Addiction, data on new diagnoses of HIV among PWID, as reported by the Health Protection Surveillance Centre, were examined. New HIV cases in two time periods (2000–2009 and 2010–2018) were compared by sex, age group, area of residence, and country of birth.
