Argentina travel health
Sources checked
Overview
Most travellers to Argentina need routine immunizations and sensible mosquito-, animal- and food‑safety precautions. Regional differences matter: the humid north and certain forested or rural areas have vector and zoonotic disease risks that differ from the large cities and Patagonia. Read the country-specific items below and check the linked official sources for location‑specific advice before you go.
Entry requirements (including COVID‑19)
Argentina currently does not require proof of COVID‑19 vaccination or a pre‑departure test for entry; travellers should still confirm airline or transit rules with carriers. Some older government notices mentioned health insurance covering COVID‑19; check official entry guidance for your nationality before travel. Argentina Ministry of Foreign Affairs — entry requirements (PDF) and the Argentine consulate guidance. Argentine Consulate in New York — entry information.
Vaccinations and entry requirements
Distinguish vaccines travellers should have (medical recommendation) from legal/entry requirements. Consult a travel‑health clinician at least 4 weeks before departure for person‑specific advice.
Routine vaccines
Make sure routine immunizations are up to date: measles‑mumps‑rubella (MMR), diphtheria‑tetanus‑pertussis (Td/Tdap), polio, varicella, and seasonal influenza. The US CDC emphasises that all international travellers should be fully vaccinated against measles before travel. CDC — Argentina travel health (routine vaccine guidance).
Hepatitis A and B
Hepatitis A vaccination is recommended for unvaccinated travellers ≥1 year old to Argentina (infants 6–11 months may receive a dose that does not count toward the routine series). Hepatitis B vaccination is recommended for unvaccinated travellers younger than 60 years and may be given to older travellers when indicated. CDC — Hepatitis A & B advice for Argentina.
Yellow fever (vaccine recommendation and entry rules)
Yellow fever vaccine is recommended for travel to the provinces of Misiones and Corrientes; it is generally not recommended for travel limited to many other provinces. Argentina’s health authority publishes local risk areas and follows WHO lists; the CDC gives province‑specific recommendations and notes that Argentina does not currently require a yellow fever certificate for entry. Check both Argentina’s yellow fever pages and CDC maps when planning travel to northern forested areas. Argentina Ministry of Health — yellow fever information and CDC — yellow fever recommendations for Argentina.
Rabies (pre‑exposure and post‑exposure care)
Rabies is present in dogs, wildlife and bats in Argentina. Consider rabies pre‑exposure vaccination if you will do remote outdoor activities, caving, extensive animal contact, or if prompt access to medical care and rabies biologics could be difficult. If bitten or scratched by an animal, wash the wound immediately and seek urgent medical care for post‑exposure prophylaxis. Argentina’s national vaccination guidance and international public health authorities describe indications for pre‑exposure vaccination. CDC — rabies advice for travellers and Argentina — national vaccination norms / rabies guidance.
Typhoid, travelers’ diarrhea and other vaccine options
Consider typhoid vaccine if you expect prolonged rural travel, poor sanitation, or will visit friends/relatives where food‑safety is uncertain. Practise food‑and‑water hygiene to prevent travellers’ diarrhea. Other vaccines (e.g., meningococcal, HPV, or additional boosters) depend on personal risk or itinerary—review with a clinician. CDC — vaccines and medicines for Argentina.
Other health risks
Non‑vaccine risks and practical prevention measures that commonly affect travellers to Argentina.
Malaria
Argentina was certified malaria‑free by the World Health Organization in 2019. Nevertheless, some travel guidance (including CDC materials) continues to caution that malaria risk has existed historically in border areas and that clinicians should consider situation‑specific chemoprophylaxis when travel includes rural/forested border zones. Note the difference: WHO certification means Argentina has interrupted indigenous transmission; CDC guidance flags route‑ or region‑specific precautions. Discuss your exact itinerary with a travel clinician. WHO — Argentina certified malaria‑free (2019) and CDC — malaria advice for Argentina.
Dengue, chikungunya and other mosquito‑borne viruses
Aedes mosquitoes transmit dengue (and occasionally chikungunya and Zika). Transmission is seasonal (typically warmer months; late spring to early autumn) and varies by province. Use insect repellent, daytime mosquito protection, and eliminate standing water around lodging. National surveillance reports show variable circulation year to year; check local bulletins for the most recent activity. Argentina — National epidemiological bulletins (dengue surveillance) and PAHO — dengue epidemiological update.
Hantavirus (Andes virus)
Andes‑group hantaviruses can cause hantavirus pulmonary syndrome (HPS) in Argentina. Rodent exposure (droppings, urine) is the common source; some person‑to‑person transmission from Andes virus has been documented in Argentina. In 2025–2026 national and regional health authorities investigated clusters and ship‑associated cases; authorities advise avoiding rodent‑infested dwellings, sealing food containers, and seeking prompt care for febrile respiratory illness after possible rodent exposure. If you develop fever and respiratory symptoms after exposure in affected areas, tell clinicians about the travel and exposure history. Argentina — Ministry of Health (hantavirus response), PAHO — hantavirus epidemiological alert, and CDC — Andes virus information.
Leptospirosis, floodwater and environmental risks
Leptospirosis occurs where people contact water or soil contaminated with animal urine (floods, muddy freshwater). Avoid wading in floodwater, wear protective footwear for flood or farm work, and seek care for febrile illness with potential exposure. CDC — leptospirosis and environmental precautions.
Chagas disease and other vectorborne infections
Trypanosoma cruzi (Chagas disease) is present in Argentina. Risk to short‑stay tourists is low but exists for prolonged stays in rural, poorly constructed housing in endemic zones; travellers should avoid sleeping in dwellings with thatched roofs or visible triatomine bug infestations and use bed nets where recommended. Argentina’s national programmes and WHO provide more detail. Argentina — Chagas information and WHO — Chagas disease Q&A.
Travelers’ diarrhea, food and water safety
Food‑ and waterborne gastrointestinal illness is common worldwide. Follow safe food and water practices (cook foods thoroughly, avoid uncooked street foods where hygiene is uncertain, use bottled/treated water for drinking and brushing teeth), carry oral rehydration supplies and ask your clinician about antibiotics or antimotility drugs only when appropriate. CDC — food and water safety for Argentina.
Current health alerts
Only active, documented events relevant to travellers are listed below. Local transmission and seasonal risk patterns may change—follow local health bulletins while travelling.
Hantavirus investigations (2025–2026)
National authorities investigated hantavirus cases and clusters reported in 2025–2026, including cases linked to cruise travel in early 2026; PAHO issued an alert for increased hantavirus activity in parts of the Southern Cone. Travellers to rural or rodent‑exposed settings should take precautions to avoid rodent contact and seek prompt care for compatible illness. Argentina — Ministry of Health report on hantavirus response and PAHO — hantavirus epidemiological alert.
Dengue seasonal circulation
Dengue incidence varies by season and province. National surveillance reported relatively low dengue circulation in the 2025–2026 season compared with recent peaks, but local increases can occur—especially in warmer months. Check provincial bulletins for up‑to‑date local risk. Argentina — national epidemiological bulletins (dengue) and PAHO — regional dengue update.
Before you travel
Plan ahead: review routine vaccines, get recommended travel immunizations, carry a summary of your medical conditions and medicines, and know where to obtain urgent care or post‑exposure treatment at your destination.
Preparation checklist
See a travel‑health clinician 4–8 weeks before departure for personalized advice and vaccines. Pack insect repellent (DEET/icaridin), a first‑aid kit, prescribed medicines, and evidence of immunization if required for other countries on your itinerary. For animal bites, seek immediate care in Argentina and report exposures to health authorities. For location‑specific updates, consult Argentine national bulletins and international agencies listed above. CDC — Argentina travel health guidance.
