Health
Poland has EU-level medical services and emergency numbers 112/999. Tap water generally meets sanitary standards, though many locals boil/filter it or use bottled water for taste. Usual food hygiene is sufficient in cities. Main outdoor risks are ticks in forests/grass, mosquitoes, summer heat/UV, cold winter weather, and fast-changing mountain conditions in the Tatras; altitude is not usually a major issue for typical visitors.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. CDC advises being up to date on routine vaccines, including MMR, polio, influenza, varicella, Tdap and shingles as applicable, plus COVID-19. Hepatitis A is recommended for unvaccinated travelers; hepatitis B is recommended for many unvaccinated travelers. Polio risk guidance has been highlighted recently. Rabies pre-exposure vaccine is only for higher-risk animal/outdoor exposure or limited access to care. Tick-borne encephalitis vaccine may be considered for extensive outdoor/tick exposure. Yellow fever vaccine is not recommended and not required for entry.
eSIM / connectivity
eSIM is widely supported in Poland. Major local mobile operators include Orange, Play, Plus and T-Mobile, all noted by Orange Flex as supporting eSIM, though activation paths differ. Orange Flex offers app-based eSIM setup and travel-data options; other carrier prepaid/eSIM availability should be checked directly before arrival. Physical SIMs remain easy to find at carrier shops and many retail points; bring passport/ID for registration.
