Vaccination record

Step-by-step

1
Register at the health unit covering your address
Take CPF and proof of address to the Unidade Básica de Saúde for your catchment. The Cartão Nacional de Saúde is free and links you to a family health team, to vaccination and to the free medicines list.

2
Take the seasonal vaccinations when the campaign opens
Influenza campaigns open in the autumn, ahead of the cold season, and are free at any unit. In a city with a real winter and a real respiratory season this is not a formality — it is the single most useful preventive thing available.
In personWho: YouFree
3
Heat and ventilate at least one room properly
Cold, damp months in uninsulated, unheated flats produce respiratory illness and mould. A split unit that heats, plus opening the flat up on dry days, is most of the answer. This is a housing decision as much as a health one, and it is worth weighing at the viewing.

4
Treat any contact with flood water as a medical history
Leptospirosis is transmitted through water contaminated with rodent urine and rose sharply after May 2024. If you have waded through flood water and then develop fever, muscle pain or jaundice within a fortnight, say so explicitly to the doctor — early treatment matters and the exposure history is what directs the diagnosis.

5
Check the tier of your employer's private plan
A plano de saúde is a standard professional benefit here and the networks vary. Ask which hospitals the specific tier admits you to — Moinhos de Vento, Mãe de Deus, Santa Casa and the Hospital Ernesto Dornelles are among the names plans are measured against — and whether the emergency department is included, not merely the outpatient clinic.

6
Or buy individually, reading the carências
Waiting periods run 24 hours for emergencies, up to 180 days for most procedures, 300 days for childbirth and up to 24 months for declared pre-existing conditions. Corporate plans often shorten or waive them.

Things most newcomers don’t know

Porto Alegre's hospital depth is a genuine reason to choose the city.

The Hospital de Clínicas de Porto Alegre is one of Brazil's leading federal university hospitals, and Moinhos de Vento is among the country's most highly regarded private institutions and a national reference for several specialties. For anyone weighing a Brazilian city on healthcare — a family with a chronic condition, an older relocation — this cluster is a stronger argument than almost anywhere outside São Paulo, and it applies on both the public and private sides.

The winter respiratory season is real here, and arrivals from northern Brazil get hit hardest.

Cold, damp months in poorly heated, poorly ventilated housing produce a genuine seasonal spike in respiratory illness that does not exist in Recife, Salvador or Manaus. People who moved from the north reliably spend their first July ill. Taking the influenza vaccination when the autumn campaign opens, and heating and airing at least one room, is most of the answer.

The 2024 flood has a health tail that is still being managed.

Beyond the immediate leptospirosis and injury burden, a disaster that displaced tens of thousands of people leaves a long mental-health load, and the municipal and state services have been carrying it since. It is worth knowing that this is acknowledged and resourced rather than taboo — and worth knowing that anyone who lived through it may have a much stronger reaction to a rainy week than a newcomer expects.

SUS covers you regardless of immigration status, and the card costs nothing.

The Brazilian constitution frames health as a universal right and SUS units do not ask about visas. Foreign residents on private plans skip registration and then have no route to routine vaccinations, repeat prescriptions or the free medicines list. One visit with a CPF and a proof of address is the whole process.

Common mistakes to avoid

Not registering for a Cartão SUS because you have private cover.
Skipping the autumn influenza campaign in a city with a real winter.
Assuming a flat with air conditioning can heat — many units cool only.
Not mentioning contact with flood water when you present with a fever.
Choosing a private plan on premium alone without reading the hospital network.
