Estimated HIV incidence (the new-infection rate) rose 13.5-fold among men who have sex with men (MSM) across Poland from 2000 to 2011. The increase was even greater in the Warsaw region.
Across Western Europe and North America, HIV incidence has been rising among MSM, especially young MSM.
A recent pan-European study found that new HIV infections almost doubled in MSM between 20 and 29 years old from 2003 to 2012.
To analyze new HIV infection trends among people in Poland, researchers conducted a descriptive analysis of surveillance data collected from 2000 through 2011. They accounted for missing data on HIV transmission category through multiple imputations.
The analysis involved 9286 new HIV diagnoses across Poland in the study period. HIV incidence ranged from 546 to 1095 new diagnoses per year. During that period, 6896 new HIV diagnoses involved men and 1943 women.
Among the 9286 new HIV diagnoses, transmission route was not known for 5615 (60.5%). Of the remaining 3671 diagnoses, 885 (24.1%) involved MSM. New infections among MSM rose from 2.5 per million men in 2000 to 33.8 per million in 2011, a 13.5-fold increase. In the Mazowieckie region, which includes Warsaw, HIV incidence among MSM rose from 2.2 to 88.8 per million men, a 40-fold jump.
Increasing HIV incidence was seen in all age groups of MSM but was most pronounced in those between 25 and 44 years old.
One factor in the rising HIV incidence among MSM could be an increase in the number of free anonymous testing centers. In 2010, 45% of MSM in Poland reported being tested at such centers.
