Four deaths, all connected to the same farm, all preventable with warning
In the interior of São Paulo state, the ancient and indifferent world of ticks and pathogens has collided with the human world of celebrations and gatherings, leaving four people dead and a community reckoning with invisible danger. Campinas, already the region with Brazil's highest spotted fever burden in 2023, now investigates a sixth suspected case tied to a single farm where people came together for music and food, unaware of what awaited them in the grass. The outbreak at Fazenda Santa Margarida is a reminder that the boundaries between festivity and catastrophe can be thinner than we imagine, and that the places we choose to celebrate can sometimes choose us back.
- A sixth person — a 40-year-old woman from Hortolândia who attended a feijoada at Fazenda Santa Margarida on May 27 — developed symptoms on June 10, deepening an outbreak that has already killed four people.
- The dead include a dentist, her businessman-pilot boyfriend, a young teacher, and a 16-year-old adolescent, all of whom visited the same farm and never returned whole.
- A fifth suspected case, a woman who attended a Seu Jorge concert at the same property, was hospitalized just hours before the sixth was announced, suggesting the exposure window may be wider than authorities first believed.
- The farm has been shuttered for 30 days, the Joaquim Egídio district declared high-risk, and new events suspended — but the people already exposed are scattered across municipalities, each a potential new notification.
- Campinas now leads all of Brazil in spotted fever cases for 2023, a grim distinction that signals not just a local crisis but a regional failure to contain a tick-borne disease that kills quickly when unrecognized.
On June 14th, health officials in Campinas confirmed a sixth suspected case of spotted fever — a forty-year-old woman from Hortolândia who had attended the Feijoada do Rosa event at Fazenda Santa Margarida on May 27th. Her symptoms appeared on June 10th, and she was admitted to a private hospital awaiting laboratory confirmation. Just hours earlier, a fifth suspected case had been announced: another woman, this one hospitalized after attending a Seu Jorge concert at the same farm. Both cases pointed to the same property, the same gatherings, the same invisible threat lurking in the grounds where people had come to eat, drink, and listen to music.
The deaths behind the numbers carried names and lives. A 36-year-old dentist from São Paulo's capital. Her boyfriend, a 42-year-old businessman and pilot from Jundiaí. A 28-year-old teacher from Hortolândia. And a 16-year-old adolescent whose cause of death was still under investigation, though the symptoms matched. All four had visited Fazenda Santa Margarida. All four had been exposed to infected ticks without knowing it.
Authorities responded by closing the farm for thirty days, suspending all future events, and classifying the Joaquim Egídio district as a high-risk zone for spotted fever transmission. The outbreak was no longer a coincidence — it was a recognized cluster, demanding official protocols and public warnings. Campinas had already recorded two other spotted fever deaths in 2023 unrelated to the farm, but the concentration of cases at Santa Margarida was something different: rapid, connected, and still unfolding. The region now holds the highest spotted fever case count in all of Brazil this year, a distinction earned in the worst possible way.
On Wednesday, June 14th, health officials in Campinas, a city in the interior of São Paulo state, received word of another suspected case of spotted fever—a disease that had already claimed four lives in the region and left the community on edge. The new case brought the total to six: four confirmed infections and two still awaiting laboratory confirmation. The woman at the center of this latest notification was forty years old, living in the nearby municipality of Hortolândia. She had attended an event called Feijoada do Rosa on May 27th at Fazenda Santa Margarida, a property located in the Joaquim Egídio district. Symptoms appeared on June 10th, and she was admitted to a private hospital in Campinas, where doctors waited for test results to confirm what they suspected.
The farm itself had become the epicenter of a public health crisis. Just hours before this sixth case was announced, authorities had learned of a fifth suspected infection—another woman who had attended a concert featuring the musician Seu Jorge at the same location. She was hospitalized on June 13th and was also awaiting test confirmation. Both women's cases pointed to the same source, the same property, the same gathering spaces where dozens of people had mingled, eaten, and listened to music.
The death toll told the grimmer part of the story. Three people had died from confirmed spotted fever infections. One was a thirty-six-year-old dentist from São Paulo's capital. Another was a forty-two-year-old businessman and pilot from Jundiaí, who had been the dentist's boyfriend. The third was a twenty-eight-year-old teacher from Hortolândia. A fourth death—a sixteen-year-old adolescent—showed symptoms consistent with the disease, but investigators were still working to determine the official cause. All four had visited Fazenda Santa Margarida. All four had been exposed to whatever was spreading there.
The outbreak had forced the farm to close its doors for thirty days. New events were suspended indefinitely. The Joaquim Egídio district, where the property sat, was now classified as a high-risk area for spotted fever transmission. This was not a localized incident anymore; it was a recognized outbreak, the kind that triggered official protocols and public warnings.
Campinas and its surrounding region had already been dealing with spotted fever cases before these farm-linked infections emerged. Two other confirmed deaths from the disease had occurred in the municipality earlier in 2023, unrelated to Santa Margarida. But the cluster at the farm was different—it was concentrated, it was connected, and it was growing. The Campinas region, in fact, now held the highest number of spotted fever cases recorded anywhere in Brazil that year. A disease transmitted by infected ticks, spotted fever had found fertile ground in this corner of São Paulo state, and the farm events had accelerated its spread among people who had no idea they were walking into danger.

A Conversa do Hearth Outra perspectiva sobre a história
Why would a farm event become a vector for this disease? What made that particular place dangerous?
Spotted fever is transmitted by ticks, and farms—especially ones hosting outdoor events—are natural tick habitats. The animals on the property, the vegetation, the people moving through it all at once. It's the perfect collision.
So these weren't people who got sick from the farm itself, but from attending parties there?
Exactly. They came for music, for food, for a social gathering. They didn't come expecting to encounter infected ticks. That's what makes it so difficult to contain—people don't know they've been exposed until symptoms appear days later.
Four deaths from a disease most people probably don't think about. How does a community respond to that?
With fear, mostly. And questions about why the farm wasn't closed sooner, why people weren't warned. The thirty-day closure is reactive, not preventive. The damage was already done.
Is this outbreak unusual for the region?
Campinas already had the highest case count in Brazil that year. This farm cluster didn't create the problem—it exposed how serious it already was. The region is a hotspot, and now everyone knows it.
