Health
Reference only, not medical advice. Food/water standards vary; use safe-water habits when uncertain, especially while hiking or in rural areas. Prevent mosquito bites: dengue, chikungunya, Zika and leishmaniasis occur, with higher concern in warmer/northern areas. Argentina was WHO-certified malaria-free, but check current clinic advice for your exact route. Plan for heat in the north/summer, strong sun and high elevation in the Andes/Northwest, cold/wind in Patagonia, and freshwater leptospirosis risk after floods or in untreated water.
Vaccinations
Consult a doctor or travel clinic at least a month before travel. Be current on routine vaccines, including MMR, polio, Tdap, flu, varicella/shingles as age-appropriate, and COVID-19. CDC recommends hepatitis A for unvaccinated travelers, hepatitis B for many travelers, and typhoid for most travelers, especially smaller cities/rural stays. Rabies pre-exposure vaccine is risk-based. Yellow fever vaccine is recommended for travelers aged 9 months or older going to Corrientes and Misiones; generally not recommended for Formosa or designated parts of Chaco, Jujuy and Salta; not recommended for other areas. A yellow-fever certificate is not required for entry to Argentina, but onward countries may have their own rules.
eSIM / connectivity
eSIM is usable for compatible phones and generally practical in major cities and tourist corridors; coverage drops in remote Andes/Patagonia areas. Main local mobile brands are Claro, Personal and Movistar, though the Movistar/Telecom deal was approved with conditions on 2026-06-18 so branding/options may change. No single official nationwide tourist eSIM/data product was found; travelers commonly use an international travel eSIM or buy/register local prepaid service with passport where available.
