Health
For most visitors, Serbia is a moderate-risk European destination: use normal food-and-water caution, especially in rural areas, markets, hiking/camping, or after floods. CDC flags tick/sand-fly and other bug-bite risks, so use repellent and tick checks outdoors. Summer heat, UV, winter cold, air pollution in cities, and limited urgent care outside major cities are practical issues; typical tourist elevations are not a major altitude concern.
Vaccinations
Consult a doctor or travel clinic before travel, ideally at least 1 month ahead. CDC advises being current on routine vaccines, including MMR, polio, flu, varicella, Tdap/Td and shingles where age-appropriate, plus COVID-19. Hepatitis A is recommended for unvaccinated travelers, hepatitis B for unvaccinated travelers of all ages. Rabies pre-exposure vaccine may be considered for animal-exposure risk; tick-borne encephalitis vaccine may be recommended/considered for extended outdoor exposure in endemic areas. Yellow fever vaccine is not recommended and Serbia does not require a yellow-fever certificate.
eSIM / connectivity
eSIM is practical in Serbia for compatible phones, especially in Belgrade, Novi Sad, Niš and other towns. The three main mobile networks are mts/Telekom Srbija, Yettel and A1 Serbia, with broad 4G and expanding 5G; visitors can also use travel eSIMs that roam on local networks. Local prepaid/tourist data is sold through carrier shops and kiosks, but eSIM availability can vary by plan and shop, so check before relying on it and bring a passport for registration.
