title: [HIV and AIDS in Poland in 2009].
abstract: In total 939 HIV cases were diagnosed in Poland in 2009 (2.46 per 100,000 population), constituting a 10% increase comparing to 2008 and 33% increase comparing to the median number in 2003-2007. The total number of incident AIDS cases in 2009 registered up to the end of 2010 was 107 (incidence 0.28 per 100,000 population). There were 42 death of AIDS patients in 2009 registered up to the end of 2010. Among the newly diagnosed HIV cases an increase of the share of infections acquired through heterosexual contact (up to 7% of all cases and 36% of cases with known transmission route) and homosexual contact between men (up to 6,7% of all cases and 34% of cases with known transmission route) were observed as compared to 2008, which reflects significant changes in HIV epidemiology in Poland, where the epidemic was for many years driven by injecting drug use. Across the country HIV infection is the most frequently detected among people aged 30 to 39 years (69.8%) and among males (76.6%). In comparison to 2008, the proportion of reports without information about the possible route of transmission increased. Furthermore, the percentage of late presenters, as defined by time between HIV and AIDS diagnoses of less than 3 months, is still high (56.1% of AIDS cases), suggesting that an important proportion of AIDS incidence could be prevented by improving testing rates. The largest group among patients with AIDS are also males and people aged 30 to 39 years. 40.2% of them were probably infected through injecting drugs.
