HIV and AIDS in Poland in 2018.

Aim: The aim of the study was to assess the epidemiological situation of newly diagnosed HIV infections and AIDS cases and death among AIDS cases in Poland in 2018 in comparison to the changes in preceding years.

Materials And Methods: Analysis of the epidemiological situation was based on reports of newly detected HIV cases and AIDS cases and the results of the annual survey of HIV testing conducted among the laboratories throughout the country.

Results: In 2018 there were 1,209 HIV cases newly diagnosed in Poland (diagnosis rate: 3.15 per 100,000), including 100 among non-Polish citizens. The frequency of newly detected HIV infections decreased by nearly 14.8% compared to the previous year and was higher by almost 6.8% compared to the median in 2012-2016 years. The total number of AIDS cases was 110 (incidence 0.29 per 100,000), and 23 people died from AIDS disease (0.06 per 100,000). New HIV diagnoses were reported mainly among people in age 30 to 39 years (37.8%) and among men (86.8%). Among cases with known transmission route, 77.0% concerned among men who had sexual contact with men (MSM). However, compared to the previous year, there was a significant decrease in the percentage of infected people in all key populations, related to higher risk of HIV infection. In addition, we observe the drop in total number of infected people in 2018 compared to the previous year. Whether these observations represent just fluctuations or a stable tendency, related to decreasing incidence in different key populations can only be assessed in the following years. The percentage of AIDS cases diagnosed at the same time with HIV diagnosis decreased by 4% percent points in comparison to 2017 (from 75.7% to 71.84% of all incident AIDS cases).

Conclusions: Despite the decreasing total number of new HIV diagnoses overall and among different key populations compared to the previous year, it is too early to conclude that these are the results of positive preventive measures. Still, all actions should be taken to ensure timely linkage to care, considering the growing number of infected people among foreigners residing in Poland, and to improve the low frequency of testing towards HIV in the whole population.
