Turn data into action before the virus becomes a crisis
Paraná operates the country's most comprehensive sentinel surveillance network for respiratory syndromes, with 34 units across all health regions providing real-time viral circulation data. The system's efficiency prevented the need for public health emergency declarations during critical viral circulation months, unlike other Brazilian states facing similar seasonal pressures.
- 34 sentinel units across all health regions in Paraná
- 1.3 million flu vaccine doses administered by May 10, 2026
- Target: vaccinate 90% of priority groups (4.5 million people)
- Paraná avoided declaring public health emergency during peak viral circulation months
Paraná's respiratory virus monitoring network of 34 sentinel units earned federal recognition as a gold standard, enabling rapid response during seasonal flu peaks without declaring public health emergencies.
As May arrives in Paraná, the state's public health apparatus shifts into high gear. The months ahead—May through July—bring the year's heaviest burden of respiratory illness. Elderly people face the steepest risk of hospitalization, alongside young children and pregnant women. But unlike other Brazilian states bracing for the same seasonal surge, Paraná has built something distinctive: a surveillance network so precise and responsive that the federal Health Ministry designated it the gold standard for flu monitoring.
The system works through 34 sentinel units distributed across every health region in the state. These are not emergency rooms or crisis centers. They are ordinary clinics and health posts where staff collect samples from patients showing respiratory symptoms. The samples travel to the state's central laboratory, where technicians sequence the genetic material to identify which viruses are circulating where. The data flows back in near-real time, feeding into the state health secretariat's decision-making: where to send vaccines, which regions need extra medication supplies, which communities need public awareness campaigns. It is epidemiology as infrastructure—constant, methodical, designed to move faster than the virus itself.
The federal government noticed. In May 2026, the Health Ministry chose Paraná to host a series of technical visits, explicitly citing the state's capacity for rapid response during the months when viral circulation peaks. More striking: while other states found themselves forced to declare public health emergencies, Paraná did not. The system had worked. César Neves, the state health secretary, framed the recognition as validation of relentless institutional effort. "Being recognized as a gold standard by the Health Ministry reflects uninterrupted work by our surveillance teams, our central laboratory, and our regional health offices," he said. "Our mission is to turn this data into practical action—expanding vaccination coverage, ensuring timely treatment, protecting the people of Paraná."
Paraná stands alone in the country with a sentinel network this comprehensive and coordinated. Maria Goretti David Lopes, who directs attention and surveillance for the state health secretariat, emphasized the strategic weight of these monitoring points. The real strength, she suggested, lies not in any single component but in how they connect: epidemiological surveillance talking to immunization programs, which talk to laboratories, which talk to hospitals. "Our goal is to deploy tools that confirm work that is articulate and prepared, so we can respond with agility to any new public health emergency," she said.
That integration deepened in early May when the state health secretariat and the federal Health Ministry held a workshop to strengthen the sentinel surveillance system. The session brought together professionals from all 22 regional health offices, municipal health departments, and the sentinel units themselves, training them to navigate seasonal respiratory virus patterns and move faster through the notification system.
Vaccination remains the primary shield. By May 10, the state had administered more than 1.3 million flu vaccine doses. Of those, over 760,000 went to people over 60, and 150,000 to children between six months and six years old—the age groups most vulnerable to severe disease. The state is running vaccination campaigns through the end of May, with some municipalities extending hours, opening on Saturdays, and bringing vaccines into schools, senior centers, and long-term care facilities. The target is to vaccinate 90 percent of priority groups—roughly 4.5 million people. The state health secretariat is waiting for additional vaccine shipments from the federal government and counting on public uptake.
The vaccine is free at all basic health units for the priority groups: children six months to six years, people over 60, pregnant women, new mothers, indigenous peoples, people with chronic conditions, and essential workers in health and education. The secretariat is pushing people to get vaccinated before winter arrives, since the body needs up to three weeks to develop full immunity. Beyond vaccination, the state is urging basic hygiene—frequent handwashing with soap and water or 70 percent alcohol gel, covering the mouth and nose when coughing or sneezing, keeping spaces well-ventilated, avoiding crowds, not sharing personal items. Anyone with sudden fever, cough, sore throat, or general malaise should seek care at a health clinic and stay away from group activities until symptoms clear. The machinery is in place. What happens next depends partly on the virus, and partly on whether people show up.

Why does Paraná's system work better than other states' systems?
Because it's built to see the virus before it becomes a crisis. Thirty-four units across the state are constantly collecting samples and sending them to the lab. The lab sequences them and sends the data back the same day. That real-time picture lets the health secretary know exactly where to send vaccines and medicine. Other states wait for hospitalizations to spike before they react.
So it's not just about having a network—it's about speed.
Exactly. Speed and integration. The surveillance team talks to the vaccination team, which talks to the hospitals. When you see a surge of one virus in one region, you can move vaccines there before people get sick enough to need a hospital bed.
The federal government called it a gold standard. What does that actually mean?
It means Paraná didn't have to declare a public health emergency during the peak months, while other states did. That's the proof. The system prevented crisis.
But the state is still pushing vaccination hard. If the system is working, why the urgency?
Because the system only works if people use it. The surveillance catches what's circulating. The vaccines prevent it from spreading. Without vaccination, you're just watching the virus win. They've given out 1.3 million doses so far, but they need to reach 4.5 million—90 percent of vulnerable people—before winter really hits.
What happens if they don't reach that target?
Then you see what other states saw: hospitals filling up, emergencies declared, the system reactive instead of preventive. The whole point of the sentinel network is to stay ahead. But you can only stay ahead if people get vaccinated.
So the recognition from the federal government—is that the end of the story, or the beginning?
It's a checkpoint. The system proved itself. Now the real test is whether the state can vaccinate enough people before the virus peaks. That's where the story goes next.
