Brazil – Health Risks, Inoculations, Vaccinations, and Health Certificates

What are the main health risks for expats living in Brazil?

The combination of Brazil’s vast geography and its extraordinary ecological range creates a health landscape that differs substantially from one region to the next. For the majority of expats, the most urgent concern is exposure to mosquito-borne illness. Diseases transmitted by mosquitoes — including dengue, chikungunya, malaria, yellow fever, and Zika — are endemic across the Amazon and surrounding tropical zones, and every resident should ensure they have received the appropriate vaccinations and consistently protect themselves against bites.

Dengue fever represents the most immediate threat for those settled in urban areas. It is the most prevalent arboviral illness in Brazil, with all four DENV serotypes actively circulating across the country. While the annual national average hovers around one million cases, Brazil recorded a dramatic escalation in 2025, with 5.9 million confirmed infections. The year 2024 saw a fourfold surge compared to 2023, along with elevated mortality rates. Crucially, this is not a rural problem — chikungunya and dengue risk is heightened in many of Brazil’s largest cities due to dense Aedes mosquito populations responsible for transmitting these viruses.

Malaria is geographically confined rather than nationwide. Transmission is largely limited to rural areas, with the greatest burden falling on Acre, Amapá, Amazonas, Rondônia, and Roraima. Malaria also occurs in Maranhão, Mato Grosso, and Pará, though it is uncommon in the urban capitals of those states. A critical point for travellers: malaria parasites in Brazil show resistance to chloroquine, meaning anyone heading to affected areas must obtain tailored advice on suitable preventive medication from a health specialist.

Yellow fever has extended its geographic footprint in recent years. Historically confined to forested inland territories, since 2017 active transmission has spread into parts of south-eastern Brazil, encroaching on areas closer to the coast and higher-density population centres. The disease remains predominantly associated with tropical and subtropical forest environments.

Leishmaniasis and Chagas disease represent additional vector-borne hazards. Brazil is responsible for more than 90% of visceral leishmaniasis cases in the Americas and approximately 37% of cutaneous leishmaniasis. Both leishmaniasis and Chagas disease are transmitted by insect bites and are not vaccine-preventable, making physical protection against bites essential. Chagas disease outbreaks have been linked to the consumption of locally produced sugar cane juice, açaí, or other foods contaminated with trypanosomes through crushed insects or their excretions, underlining the importance of food hygiene vigilance.

Waterborne and foodborne illness pose a persistent everyday risk. Infections linked to contaminated food, water, and other environmental sources are common throughout Brazil. Drinking boiled or commercially bottled water and avoiding raw or undercooked food are fundamental precautions for all residents.

Other environmental and emerging risks include extreme heat, urban air pollution, and hantavirus. Heat-related conditions, up to and including potentially fatal heatstroke, are a genuine concern — wearing loose, lightweight clothing, maintaining adequate fluid intake, and curtailing physical exertion during peak heat are all advisable habits. Brazil has recorded more than 2,000 hantavirus cases across all five of its geographic regions. Urban residents face low risk, but those staying in suburban, semi-rural, or rural accommodation where rodent exposure is more likely face elevated risk.

Are any vaccinations or inoculations required before entering Brazil?

A clear distinction must be drawn between vaccinations that are legally obligatory for entry and those that are recommended on health grounds. As directed by the National Health Surveillance Agency (ANVISA), Brazil’s authority responsible for traveller health regulation, no yellow fever vaccination is mandated for foreign visitors or Brazilian nationals returning to Brazil. That said, even without a compulsory proof-of-vaccination requirement at the border, Brazil’s Ministry of Health advises that all international visitors ensure their immunisations are current before arriving.

There is, however, a notable exception affecting those arriving from certain countries. If you have passed through Angola or the Democratic Republic of Congo — both classified as yellow fever endemic areas — within the six days preceding your arrival in Brazil, you must present a valid yellow fever vaccination certificate at the point of entry, with an exception applying only to children under nine months of age. Expats arriving from other yellow-fever-endemic countries should review current entry requirements before departure.

Furthermore, once resident in Brazil, you should be mindful that neighbouring countries enforce their own standards. Colombia, French Guiana, Suriname, Guyana, Bolivia, and Paraguay all require travellers arriving from Brazil to provide evidence of yellow fever vaccination and, in some cases, other immunisations. If you intend to travel across borders within South America, carrying your International Certificate of Vaccination — known in Brazil as the Caderneta de Vacinação or CIVP — is essential.

A further point worth noting: in July 2016, the WHO formally revised the International Health Regulations to confirm that a completed International Certificate of Vaccination or Prophylaxis remains valid for the lifetime of the recipient, and that yellow fever booster doses are no longer considered necessary. However, individual countries may still impose their own booster requirements, so confirming the latest position with a travel health clinic before any regional travel is advisable.

As of 2025, there are no health certificate requirements tied specifically to standard tourist entry into Brazil. Requirements relevant to long-term visa and residency applicants are discussed in the dedicated section below. For the most current information, consult the Brazilian Ministry of Health traveller health pages and the ANVISA vaccination certificate service before you travel.

Which vaccinations are recommended for expats moving to Brazil?

For those making a long-term move to Brazil rather than a short visit, the range of immunisations that deserve consideration is considerably broader. Brazil’s Ministry of Health recommends that all international arrivals be up to date on their vaccinations before entering the country — with particular emphasis on COVID-19, yellow fever, polio, measles, rubella, diphtheria, and tetanus. Hepatitis A vaccination is also recommended for all travellers regardless of their intended destination within Brazil.

Drawing on guidance from the CDC and other international health bodies, the full list of vaccinations recommended for Brazil includes: typhoid, hepatitis A, polio, yellow fever, chikungunya, rabies, hepatitis B, influenza, COVID-19, pneumonia, meningitis, chickenpox, shingles, Tdap (tetanus, diphtheria, and pertussis), and MMR (measles, mumps, and rubella). Not every vaccine on this list will be relevant to every individual — your personal health history, age, and the specific part of Brazil in which you will be living should all shape the final selection.

The following vaccines deserve particular attention for long-term residents:

• Yellow fever: Though not a mandatory requirement within Brazil, vaccination is advised for all travellers — both foreign nationals and Brazilians — at a minimum of ten days before departure, the period needed for the vaccine to generate protective antibodies. Yellow fever vaccination is recommended for the majority of Brazil’s territory; only travellers whose itineraries are confined to Fortaleza and Recife are generally considered outside the recommended vaccination zone.
• Chikungunya: This vaccine is worth considering for travellers aged 65 and over — especially those with pre-existing health conditions — who anticipate spending two weeks or more in mosquito-prone regions. It should also be considered for adults aged 18 and over who are planning an extended stay of six months or longer.
• Hepatitis A and B: Hepatitis A spreads through food and water that has been contaminated; vaccination combined with good hygiene practices offers robust protection, particularly in regions with less reliable sanitation. Hepatitis B is advisable for anyone who may require medical or dental treatment in Brazil, or who faces other occupational or social exposure risks.
• MMR (measles, mumps, rubella): Measles outbreaks recur periodically in Brazil. Maintaining up-to-date MMR vaccination, practising regular handwashing, and avoiding close contact with unwell individuals are the main protective strategies.
• Typhoid: Recommended for those who will eat outside formal catering environments or live in settings with limited sanitation infrastructure. The injectable formulation offers two years of protection, while the oral form provides five years.
• Malaria prophylaxis: Chemoprophylaxis is necessary for anyone travelling to malaria-endemic zones within Brazil. Prescriptions should be obtained before departure and the full course carried for the entire duration of the stay in a risk area.

Given Brazil’s role as a host country for large-scale public events and mass gatherings, those attending such occasions should also consider the meningococcal vaccine along with a seasonal influenza vaccination.

Several vaccines on the broader list — such as hepatitis B or Tdap — may already be included in standard vaccination programmes in your home country. Others, such as yellow fever or typhoid, may be less familiar. A specialist travel health clinic can review your existing immunisation record and identify precisely which vaccines are new requirements or need refreshing. Book a consultation at a travel health clinic at least six to eight weeks before your departure to allow sufficient time for multi-dose vaccine series and for individual vaccines to reach full protective effect.

Do you need a health certificate to move to or work in Brazil?

Brazil does not apply a universal medical examination requirement to all immigration applicants, but health documentation is required in specific situations. The exact requirements depend on your visa category, your country of origin, and the procedures of the Brazilian consulate handling your application.

Applicants for certain long-stay or permanent residency visas — particularly those related to employment or regulated professional categories — may find that the issuing consulate requires a medical certificate as part of the supporting documentation. Such a certificate typically confirms that the applicant is free from active communicable disease and in a general state of health compatible with residence in Brazil. Depending on the consulate, requirements may include a general medical assessment, blood tests, and in some cases a chest X-ray, which is a standard measure in many countries’ immigration health screening programmes as a tool for tuberculosis detection.

Medical examinations conducted for Brazilian visa purposes are ordinarily carried out by approved or panel physicians in the applicant’s country of current residence, or at an authorised clinic. For those already residing in Brazil who are transitioning to a long-term or permanent residency visa, the examination may be completed locally through the Brazilian public health system or a licensed private clinic. Results are typically available within a few days to two weeks, depending on which tests are needed and the clinic’s processing time.

The cost of medical examinations varies according to the clinic, the city, and the specific tests involved. As of 2025, fees at private clinics in Brazil for a standard health assessment with blood work typically range from BRL 300 to BRL 1,000 or more. For authoritative and current requirements, consult the visa-issuing consulate directly or refer to the Brazilian Ministry of Justice and Public Security (migration authority), as these details are subject to revision.

If you hold recent health documentation from your home country — for example, a comprehensive health check or blood panel — it is worth asking your consulate whether this will be accepted in place of a locally conducted examination, since policies differ between consulates and visa types. Directing specific questions about health certificate requirements to the Brazilian consulate or embassy in your country of residence, well in advance of any visa appointment, is always the most reliable approach.

How does healthcare in Brazil compare to what expats may be used to?

Healthcare in Brazil is organised along a mixed public-private model. Brazil’s 1988 Constitution enshrines health as a universal right and a state obligation, and the government created the Sistema Único de Saúde (SUS) to deliver free care to the entire population. Rather than operating as a purely public delivery system, the SUS draws significantly on private providers working under public funding arrangements. All legal residents of Brazil — including expats — are entitled to SUS care, with costs covered through taxation so that patients incur no direct charges at the point of service.

To access the public system as an expat, your National Migratory Registry Card and taxpayer identification number (CPF) are the key documents required to enrol for a National Health Card (CNS). This card grants access to public hospitals and clinics at no cost and can be obtained at a municipal health office, a hospital, or a community clinic, with the card typically issued on the same day.

In practice, however, the public system faces significant structural pressures. Facilities are frequently overcrowded, medical equipment can be outdated, and waiting times for care are often lengthy. In 2024, the Ministry of Health reported that elective surgery queues in major urban centres commonly exceed twelve months. Emergency care presents a different picture — in any medical emergency, every public hospital is legally obligated to treat you regardless of insurance status or nationality.

The private sector offers a substantially different standard of care. While the public system operates under considerable strain, private hospitals and clinics deliver quality broadly equivalent to — and in some cases exceeding — that found in European or North American healthcare systems, with internationally trained specialists and state-of-the-art facilities. Brazil leads South America with six hospitals appearing in Newsweek’s 2024 World’s Best Hospitals ranking, and 25 Brazilian hospitals hold accreditation from the Joint Commission International (JCI).

Expats considering private health coverage — referred to locally as a plano de saúde — should expect to pay roughly USD $100–300 per month for a comprehensive policy, with the precise figure depending on age, coverage tier, and geographic scope (as of 2024). All private health plans are regulated by the ANS (Agência Nacional de Saúde Suplementar), which sets mandatory minimum coverage standards.

On the matter of language: in major cities such as Rio de Janeiro and São Paulo, the standard of care is delivered in Portuguese, though English-speaking professionals are more readily found in private facilities. In rural and more remote areas, healthcare staff may speak only Portuguese. Contacting your private insurer, your embassy, or hotel staff for referrals to English-speaking providers is a practical first step when navigating language barriers.

Outside major metropolitan centres, healthcare infrastructure can be markedly limited — shortages of specialists, outdated equipment, and restricted access to complex treatments are common features. Expats based in smaller towns or remote areas may regularly need to travel to larger cities for specialist consultations or elective procedures. The emergency ambulance number in Brazil is 192 (SAMU), and the nationwide network of 24-hour urgent care units known as UPAs offers a faster alternative to full hospital emergency departments for non-critical situations.

What are the risks of travel within Brazil, and are there regional health differences?

Ranked fifth in the world by land area, Brazil is subdivided into five geographic regions — North, North-east, Central-West, South-east, and South — encompassing 27 federative units and 5,570 municipalities. Health risks closely mirror these regional divisions, and expats who plan to travel domestically or relocate within Brazil should understand how the disease profile shifts from one area to another.

The Amazon and North region represent the highest-risk zone for malaria, yellow fever, and leishmaniasis. Both cutaneous and visceral leishmaniasis are most prevalent in the Amazon and North-east regions. Active malaria transmission is widespread across Acre, Amapá, Amazonas, Rondônia, and Roraima, and chemoprophylaxis is recommended for anyone spending time in rural Amazonian areas. The Amazon and Acre regions are also currently experiencing Oropouche fever outbreaks, a disease transmitted by infected midges and mosquitoes; consistent use of insect repellent is essential throughout this zone.

The South-east region (São Paulo, Rio de Janeiro, Minas Gerais) has seen yellow fever extend its reach since 2017, with transmission documented in areas closer to the coast and to more heavily populated zones. Dengue fever is a significant and well-established urban risk throughout the South-east, and Brazil’s cyclical dengue transmission patterns create peaks of high morbidity and mortality that disproportionately affect this region, along with the Central-West and North-east.

The North-east region encompasses cities such as Fortaleza and Recife, which fall outside the yellow fever vaccination recommendation zone. Nevertheless, dengue and chikungunya remain prevalent throughout this region. First detected in Brazil in 2014 and peaking in 2016, chikungunya has since settled into an annual pattern of 70,000–170,000 reported cases, with the North-east and South-east collectively accounting for roughly 90% of the national case burden.

The Iguaçu Falls area (South region) sees chikungunya, dengue, and Zika circulating in both urban and rural settings. Yellow fever vaccination is recommended for all visitors to this area, including those on brief one- to two-day itineraries. Importantly, there is no malaria transmission risk at Iguaçu Falls.

Urban air quality and heat are additional considerations in larger cities. São Paulo in particular experiences significant air pollution driven by vehicle emissions and seasonal biomass burning in the cerrado and Amazon. Residents with respiratory conditions should monitor local air quality indexes regularly. Across the country’s tropical zones, intense heat and high humidity are year-round realities; expats arriving from cooler climates should acclimatise gradually and maintain high fluid intake.

Dengue transmission follows seasonal patterns tied to the rainy season — in south-eastern Brazil this runs from November to March, while on the North-east coast it typically peaks between April and July. Factoring local disease seasons into your arrival and early settlement timeline is a sensible precautionary measure.

Where can expats get reliable and up-to-date health advice for Brazil?

Health requirements, disease outbreaks, and official recommendations can shift rapidly. Consulting authoritative sources before finalising your health preparations — and revisiting them periodically once you are living in Brazil — is essential practice. The key official resources are listed below:

• Brazilian Ministry of Health — Traveller Health: The definitive source for Brazil-specific health guidance, vaccination schedules, and disease surveillance data. gov.br/saude — Saúde do Viajante
• ANVISA (National Health Surveillance Agency): Brazil’s regulatory body for travel health requirements and vaccination certificates. The International Vaccination Certificate (CIVP) is obtainable through ANVISA. gov.br/anvisa
• World Health Organization (WHO) — Brazil country page: Provides epidemiological data, disease outbreak notifications, and vaccination requirements for international travel. who.int/countries/bra
• US Centers for Disease Control and Prevention (CDC) — Brazil traveller health: One of the most comprehensive and frequently updated destination-specific health resources available, including the CDC Yellow Book. CDC Travellers’ Health: Brazil
• UK Travel Health Pro (NaTHNaC): Published by the National Travel Health Network and Centre, this resource provides detailed country health profiles for residents and long-stay travellers alike. travelhealthpro.org.uk — Brazil
• Brazilian Ministry of Justice — Migration Authority: For requirements relating to health certificates and residency visas. gov.br/mj — Migration
• ConecteSUS / Meu SUS Digital app: This application stores your digital CNS card, vaccination history, and clinical records. Access is via your Gov.br account (a CPF number is required). Your COVID-19 and yellow fever vaccination certificates are held here — an important resource for onward travel documentation.

Please note that specific requirements, fees, and vaccination recommendations are subject to change. Always verify the latest details with official Brazilian government sources or your national health authority prior to travel, and review them again before undertaking any domestic travel within Brazil.

Frequently Asked Questions

Will my vaccinations from home be accepted in Brazil?

Brazil’s entry rules do not currently require proof of vaccination for most arrivals (as of 2025), so there is no formal acceptance procedure for routine vaccines at the border. If, however, you need to obtain an International Certificate of Vaccination (CIVP) for onward travel to neighbouring countries, you will need to have received the relevant vaccines at an ANVISA-approved vaccination centre in Brazil, or be in possession of a recognised international vaccination document. Keeping your original vaccination records and having them translated into Portuguese where possible is advisable. Direct specific recognition queries to ANVISA or the relevant consulate.

Is health insurance required to obtain a Brazilian visa or residency?

Proof of health insurance is not a universal requirement across all Brazilian visa categories, but it is strongly advisable and may be requested for certain visa types. Many long-stay visa applicants are expected to demonstrate that they have access to adequate healthcare. Even where it is not formally demanded, comprehensive private health insurance is highly recommended for all expats given the waiting times and accessibility limitations of the public SUS system. Confirm the current requirements with the Brazilian consulate handling your specific visa application.

What should I do if I develop a serious illness while living in Brazil?

In the event of a medical emergency, every public hospital in Brazil is required by law to treat you regardless of your insurance status, SUS registration, or nationality. Dial 192 to reach the SAMU public ambulance service. If you hold private health insurance, contact your insurer’s 24-hour assistance line as a priority — they will direct you to an appropriate network hospital and may need to pre-authorise treatment to avoid out-of-pocket expenses. For urgent but non-life-threatening situations, UPA (Unidade de Pronto Atendimento) centres are open around the clock and see patients free of charge on a walk-in basis.

How do I find an English-speaking doctor in Brazil?

English-speaking medical professionals are most readily found in private facilities in major cities such as Rio de Janeiro and São Paulo. In rural and smaller urban areas, physicians may work exclusively in Portuguese. Your embassy or consulate generally maintains a list of local doctors with foreign language capabilities. Your private insurer’s assistance line can similarly direct you to network providers who speak your language. Internationally accredited hospitals — particularly JCI-accredited facilities in São Paulo — typically employ multilingual staff and operate dedicated international patient services.

Is tap water safe to drink in Brazil?

Tap water quality is inconsistent across Brazil. In major cities such as São Paulo and Rio de Janeiro, tap water is chemically treated and technically meets safety standards, but variable infrastructure leads many residents and expats to opt for filtered or bottled water as a precaution. In smaller towns, rural communities, and throughout the Amazon region, tap water should not be consumed without first boiling or filtering it. Waterborne illnesses including typhoid and hepatitis A are genuine risks across much of the country, and vaccination against both is recommended for all long-term residents.

Are there any vaccinations I should get specifically because of Brazil’s dengue situation?

In 2024, Brazil became the first country in the world to incorporate Takeda’s TAK-003 (Qdenga®) dengue vaccine into its national public health system. However, availability varies and the vaccine is not yet broadly accessible in all countries or formally approved for all traveller groups. Eligibility criteria differ depending on the jurisdiction. Before your departure, raise the dengue vaccine specifically with a travel health clinic, as recommendations may vary based on your age, previous dengue exposure history, and home country. Since no dengue vaccine has universal approval for all traveller profiles, consistent mosquito bite prevention remains the most fundamental form of protection.

Do I need to take malaria tablets if I am only living in São Paulo or Rio de Janeiro?

No malaria transmission occurs in the cities of Brasília, Rio de Janeiro, or São Paulo, so chemoprophylaxis is not required for expats living in these major urban centres. However, if your plans include travel to the Amazon region or rural areas within high-risk states such as Acre, Amazonas, or Rondônia, you should seek specialist travel health advice about suitable prophylactic medication well ahead of your trip, as certain medications must be started before you enter the risk area.

How do I register for Brazil’s public healthcare system (SUS) as an expat?

The SUS extends universal coverage to all legal residents of Brazil, including expats who hold valid documentation. Enrolling is a straightforward process carried out at a local health centre (Unidade Básica de Saúde or UBS) using your passport, residence permit, and proof of address. Your National Health Card (CNS) is issued on the same day as registration and provides access to public hospitals and primary care facilities at no charge. Even expats who hold private health insurance are encouraged to obtain a CNS card: it grants access to free vaccinations through Brazil’s national immunisation programme and provides a reliable safety net for emergency hospital care in the public system.
