The worst was over, but the work would never stop.
Em Catanduva, uma cidade do interior paulista, os primeiros quatro meses de 2026 revelaram algo raro na história recente da saúde pública local: o recuo expressivo de uma doença que, no ano anterior, havia sobrecarregado famílias e serviços de saúde. A redução de 93% nos casos de dengue — de 5.557 para 380 — não surgiu do acaso, mas de um esforço cotidiano, silencioso e persistente de agentes que percorreram ruas, quintais e consciências. É o tipo de vitória que não ocupa manchetes com a mesma intensidade que as crises, mas que representa, talvez, o mais honesto retrato do que a saúde coletiva pode alcançar quando sustentada com método e presença.
- Em 2025, Catanduva enfrentou uma onda de dengue que chegou a 1.835 casos em março — um único mês — pressionando clínicas, famílias e a capacidade de resposta municipal.
- A virada veio número a número: cada mês de 2026 registrou uma fração do que o mesmo período do ano anterior havia imposto, tornando a queda impossível de ignorar.
- O peso da doença não se distribuiu de forma igual — o Distrito 3, com 98 casos confirmados, concentrou a maior carga, enquanto o Distrito 5 registrou o menor número, com 53.
- A resposta que produziu esses resultados foi construída sobre visitas domiciliares, eliminação de criadouros, nebulizações estratégicas e educação comunitária — trabalho sem glamour, mas de efeito mensurável.
- Com o pico sazonal se encerrando, a cidade não celebra o fim do dengue, mas uma transição: da gestão de crise para algo que se aproxima do controle sustentado.
Os números divulgados pela Secretaria Municipal de Saúde de Catanduva em 15 de maio contavam uma história de reversão. Entre janeiro e abril de 2025, a cidade havia registrado 5.557 casos de dengue. No mesmo intervalo de 2026, esse total caiu para 380 — uma redução de 93% que se repetiu, mês a mês, sem exceção.
Janeiro passou de 1.212 para 68 casos. Fevereiro, de 1.672 para 94. Março — o pico mais severo do ano anterior, com 1.835 registros — recuou para 144. Abril fechou com 74 casos, contra 838 em 2025. Cerca de 40 casos seguiam sob investigação, mas a direção era inequívoca: a janela mais perigosa da transmissão estava se fechando.
A doença, porém, não recuou de forma uniforme pela cidade. Dividida em cinco distritos sanitários, Catanduva viu o Distrito 3 — que abrange as unidades de Parque Glória, Lunardelli, Nosso Teto e Jardim Salles — registrar a maior concentração, com 98 casos confirmados. O Distrito 4, com 87 casos, ficou em segundo lugar. Os demais distritos variaram entre 53 e 80 casos, mostrando uma doença ainda presente, mas contida.
A Secretaria atribuiu a queda ao trabalho da Equipe Municipal de Controle do Aedes Aegypti, que, em parceria com agentes comunitários de saúde, manteve presença diária nos bairros. Visitas domiciliares, eliminação de criadouros, nebulizações, armadilhas de monitoramento e campanhas educativas compuseram uma rotina sem espetáculo — e aparentemente eficaz.
O fim do pico sazonal não significa o fim do mosquito nem da vigilância. Mas Catanduva encerra esses primeiros meses de 2026 com algo que o ano anterior não ofereceu: a possibilidade de respirar com menos urgência, sabendo que o momento mais crítico já passou.
The numbers arrived on a Friday afternoon in mid-May, and they told a story of something breaking. In the first four months of 2025, Catanduva had recorded 5,557 cases of dengue. In the same stretch of 2026, that figure had collapsed to 380. The Municipal Health Department released the figures on May 15th, and the message was unmistakable: the worst was over.
Month by month, the pattern held. January had seen 1,212 cases the year before; now it was 68. February dropped from 1,672 to 94. March fell from 1,835 to 144. April went from 838 to 74. The arithmetic was stark—a 93 percent reduction across the board. The health department noted roughly 40 additional cases still under investigation, but the trajectory was clear. The peak season, that dangerous window when the mosquito thrived and the virus spread fastest, was closing.
The disease had not vanished evenly across the city. The health system divides Catanduva into five districts, and the burden had settled unevenly. District 3, which includes the health clinics at Parque Glória, Lunardelli, Nosso Teto, and Jardim Salles, carried the heaviest load with 98 confirmed cases. District 4, anchored by the Central clinic and serving neighborhoods like Jardim Del Rey, Gavioli, Santo Antônio, and Theodoro Rosa Filho, followed with 87. The remaining three districts—District 2 with 80 cases, District 1 with 60, and District 5 with 53—showed the disease distributed but contained.
The health department attributed the decline to sustained, methodical work. The Municipal Team for Aedes Aegypti Control, working alongside community health agents, had maintained a daily presence in the neighborhoods. They visited homes, searched for and eliminated breeding sites in standing water, conducted strategic spraying operations, deployed monitoring traps, organized community cleanup efforts, and ran educational campaigns. It was not dramatic work. It was the opposite of dramatic—it was relentless, unglamorous, and apparently effective.
What mattered now was whether the decline would hold. The end of the peak season did not mean the end of dengue itself. The mosquito would persist. But if the pattern held through the drier months ahead, Catanduva would have moved from crisis management to something closer to control. The work would continue. The visits would continue. The traps would continue. But the city could breathe differently now, knowing that the worst of this year had already passed.

The Hearth Conversation Another angle on the story
Why does a 93 percent drop matter so much? Isn't dengue always seasonal?
It is seasonal, yes. But the difference between 1,200 cases in a month and 68 is the difference between a health system overwhelmed and one that can actually function. It's the difference between people dying and people recovering.
Where did the cases concentrate most heavily?
District 3 had the worst of it—98 cases. That's the neighborhoods around Parque Glória and Lunardelli. But it wasn't just one area. All five districts had cases. The disease doesn't respect boundaries.
What actually stopped it? Was it the spraying?
The health department credits the whole system working together—home visits, eliminating standing water where mosquitoes breed, the spraying, the traps, the education. It's not one thing. It's consistency. Every day, the same teams doing the same work.
Does this mean dengue is gone from Catanduva?
No. It means the peak has passed. The mosquito is still there. The virus is still there. But the conditions that allowed it to explode have been interrupted. Whether it stays interrupted depends on whether the work continues.
What happens now?
The work continues. The teams keep visiting homes, keep looking for breeding sites, keep monitoring. The season is ending naturally, but the vigilance doesn't stop. That's how you prevent the next spike.
