In Poland, data on human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are collected by the National Institute of Public Health — National Institute of Hygiene (NIPH-NIH). Out of the total number of new cases of HIV infection notified in 2017, an estimated 6 % were attributed to injecting drug use. Overall, the number of newly reported cases of HIV infection among people who inject drugs (PWID) indicates a downward trend. However, the transmission route remains unreported in a large proportion of new cases of HIV infection.

Notification data on HCV and HBV infections indicate that fewer than 1 in 10 chronic HCV infections in which the transmission route was known in 2016 were attributed to injecting drug use, while only a few cases of chronic HBV infection were linked to injecting drug use. In a seroprevalence study conducted in 2017 in low-threshold services of four cities, the prevalence of HCV antibodies among PWID ranged from 38 % to 75.8 %, while the prevalence of people testing positive for the HBV surface antigen (HBsAg), which indicates chronic HBV infection, ranged from 2 % to 5.4 %.
