Current state of HIV and associated infections epidemic among adolescents and youth: LATVIA Anda Karnite, MPH, PHD Riga Stradins University and Baltic HIV Association St Petersburg, 27th November 2013

Number of newly registered HIV and AIDS cases in Latvia ( )

HIV incidence and prevalence rates in Latvia (registered cases) ( )

Number of HIV tests performed in Latvia

Number of newly registered HIV cases by mode of transmission in Latvia ( )

The Latvian HIV-1 outbreak among intravenous drug users (IDUs) in 1997–1998 involved subtype A1.... We estimated that subtype A1 was introduced from Former Soviet Union around 1997 and initially spread explosively among IDUs in Riga. A recent increase of heterosexually infected persons did not form a separate subepidemic, but had multiple interactions with the IDU epidemic. Subtype B was introduced before the collapse of the Soviet Union and primarily has spread among men who have sex with men.

Subnational differences in HIV prevalence (end of 2012; per 10,000 inhabitants) 13.1 Pierīga

Studies on HIV prevalence among PWID in Latvia

Furthermore, our model shows that social heterogeneity of the susceptible population can explain the shift in HIV-1 incidence in Latvia over the course of the epidemic. Thus, the decrease in IDU incidence may be due to local heterogeneities in transmission, rather than the implementation of control measures. Increases in susceptibles, through social or geographic movement of IDU, could lead to a boost in HIV-1 infections in this risk group.
