Every state in Brazil now has severe respiratory cases at alert level or higher
Em pleno outono do hemisfério sul, o Brasil enfrenta uma convergência rara de três vírus respiratórios circulando simultaneamente em todos os seus estados, revelando tanto a vulnerabilidade perene dos sistemas de saúde quanto a desigualdade etária do sofrimento — crianças adoecem, idosos morrem. A Fundação Oswaldo Cruz, sentinela histórica da saúde pública brasileira, lança um alerta que é também um convite: as ferramentas de proteção existem, mas dependem da escolha coletiva de usá-las.
- Todos os estados brasileiros atingiram nível de alerta para síndrome respiratória aguda grave, e 18 deles — incluindo o Ceará — registram crescimento contínuo de casos há seis semanas seguidas.
- Três vírus avançam ao mesmo tempo: o VSR domina os casos graves com quase metade das confirmações, o rinovírus atinge crianças e adolescentes de forma desproporcional, e a influenza A responde por quase metade das mortes por vírus respiratórios.
- O sistema hospitalar absorve uma pressão crescente: mais de 77 mil casos de SRAG registrados no ano, com quase 7 mil resultados laboratoriais ainda pendentes.
- A mortalidade concentra-se nos idosos, enquanto Ceará, Maranhão e Pará enfrentam ainda a circulação simultânea de COVID-19, tornando o cenário epidemiológico ainda mais complexo.
- A Fiocruz reforça que a vacinação é a principal resposta disponível, mas sua eficácia depende de adesão ativa dos grupos elegíveis — crianças, idosos e pessoas com doenças crônicas.
Os hospitais brasileiros estão recebendo um volume crescente de pacientes com doenças respiratórias graves. O boletim semanal da Fundação Oswaldo Cruz, divulgado nesta semana com dados de 24 a 30 de maio, deixa claro que o problema é simultâneo e abrangente: todos os estados do país registram casos de síndrome respiratória aguda grave em nível de alerta ou superior. Em 18 estados, incluindo o Ceará, os casos crescem semana após semana há seis semanas consecutivas — um padrão que indica onda sustentada, não pico passageiro.
Três vírus impulsionam esse cenário ao mesmo tempo. O vírus sincicial respiratório lidera, responsável por 48,5% dos casos graves confirmados nas últimas quatro semanas, com impacto especial em crianças pequenas. O rinovírus ocupa o segundo lugar e afeta principalmente crianças e adolescentes. A influenza A, com 21,9% dos casos, é a mais letal: responde por quase metade das mortes por vírus respiratórios confirmados no período, vitimando sobretudo os idosos.
O volume total é expressivo: 77.153 casos de SRAG registrados no Brasil em 2026, dos quais mais de 37 mil com vírus identificado e quase 7 mil ainda aguardando resultado laboratorial. Ceará, Maranhão e Pará enfrentam ainda circulação ativa de COVID-19, somando mais uma camada ao quadro respiratório regional.
Diante desse cenário, a pesquisadora Tatiana Portella, da Fiocruz, reafirma a mensagem central da saúde pública: a vacinação é o principal instrumento para evitar os desfechos mais graves. Crianças, idosos e pessoas com condições crônicas precisam manter seus esquemas vacinais em dia. Os vírus circulam amplamente, os danos são mensuráveis — e as ferramentas de proteção existem.
Across Brazil, hospitals are seeing more patients arrive with severe respiratory illness than they were weeks ago. The Oswaldo Cruz Foundation, the country's premier public health research institution, released its weekly respiratory surveillance report this week with a clear message: the problem is spreading everywhere at once, and it's being driven by three viruses circulating simultaneously.
The data covers the week of May 24 through May 30, and it shows that every single state in Brazil now has severe acute respiratory syndrome cases at alert level or higher. Eighteen states—including Ceará in the Northeast—are not just dealing with the current surge; they're seeing cases climb week after week over the past six weeks. The pattern suggests this is not a temporary spike but a sustained wave.
Respiratory syncytial virus, or RSV, is doing the most damage right now. In the past four weeks, it has accounted for nearly half of all confirmed severe respiratory cases—48.5 percent. Rhinovirus is second, responsible for just under a quarter of cases, and it's hitting children and adolescents particularly hard. Influenza A rounds out the trio at 21.9 percent of cases. What makes influenza notable is its lethality: among deaths from confirmed respiratory viruses during this period, influenza A was responsible for nearly half. The virus is killing older people at rates that dwarf the other pathogens.
The numbers are substantial. Brazil has recorded 77,153 cases of severe acute respiratory syndrome so far this year. Of those, 37,153 came back positive for one of the respiratory viruses being tracked. Another 27,841 tested negative. The remaining 6,934 cases are still waiting for lab results. The sheer volume moving through the system suggests hospitals across the country are under real pressure.
The age pattern is stark. RSV is predominantly a disease of young children right now—the foundation notes that incidence remains highest among small children, driven by RSV circulation. But when it comes to death, the elderly dominate. They are the ones dying from influenza A, and they are the ones most vulnerable to severe outcomes across the board. Ceará, along with Maranhão and Pará, are among the few states where COVID-19 cases are also still climbing, adding another layer to the respiratory illness picture.
Tatiana Portella, a researcher at the foundation's Scientific Computing Program, offered the institution's core message: vaccination is the primary tool available to prevent severe illness and death from these viruses. The eligible groups—which include children, the elderly, and people with chronic conditions—need to keep their vaccination schedules current. It's a straightforward public health recommendation, but it carries weight given what the data is showing. The viruses are circulating widely. The damage they cause is real and measurable. And the tools to prevent the worst outcomes exist, but only if people use them.

Vaccination remains the primary measure of prevention against severe cases and deaths from respiratory viruses, especially influenza, COVID-19, and RSV— Tatiana Portella, Oswaldo Cruz Foundation Scientific Computing Program
The Hearth Conversation Another angle on the story
Why is RSV hitting so hard right now when we usually think of it as a winter virus?
The data doesn't explain the seasonal shift, but RSV is circulating across multiple regions simultaneously—North, Northeast, Southeast, South. It's possible we're seeing a broader circulation pattern than in previous years, or the virus is finding more susceptible populations.
So when you say 18 states show six-week growth trends, what does that actually mean for a hospital administrator?
It means the surge isn't a one-week blip. It's sustained. You can't assume it will pass in days. You're planning for weeks of elevated patient volume.
The death numbers are striking—influenza A at 49 percent of respiratory deaths. Why is influenza so much deadlier than RSV?
Age matters enormously. RSV is hitting children, who generally survive it. Influenza is killing the elderly, whose immune systems can't mount the same defense. A virus that's common in one age group can be lethal in another.
Ceará is mentioned specifically several times. Is the Northeast in worse shape than other regions?
The data shows RSV growth across multiple regions, but Ceará is flagged for growth in both RSV and rhinovirus cases. It's not isolated to the Northeast, but the Northeast is definitely in the surge.
What does "eligible groups" mean for vaccination? Who exactly needs to act?
Children, elderly people, and anyone with chronic conditions. The foundation is saying these groups need to check their vaccination status now, not wait until symptoms appear.
