One in five people walking through the doors, all with something wrong in their lungs
Every winter, the ancient tension between human fragility and institutional capacity reasserts itself, and Curitiba is living that moment now. In the first three weeks of May, nearly 81,000 people sought urgent care across the city's nine UPAs, one in five of them carrying some form of respiratory illness — the cold season's familiar toll. Authorities are not in crisis, but they are navigating the narrow corridor between a system that holds and one that buckles, redirecting the mildly ill toward remote care while keeping the doors open for those who truly cannot wait.
- Curitiba's nine UPAs absorbed over 80,000 patients in three weeks, with respiratory cases accounting for more than 17,000 visits — a volume that is visibly bending wait times.
- Patients with minor respiratory complaints now wait between 86 and 109 minutes before seeing a doctor, a delay that feels long when you are feverish and watching the clock.
- Critical patients continue to receive immediate attention, meaning the triage system is functioning — but the sheer weight of mild cases is compressing the space around it.
- The city is actively rerouting non-urgent cases to a remote consultation line, operating most of the day on weekdays and weekends, to prevent the emergency units from reaching a breaking point.
- Flu vaccination continues at 109 facilities across the city, a quiet upstream effort to reduce the number of people who will eventually need those waiting room chairs.
The cold has returned to Curitiba, and the emergency rooms are filling with it. Across the city's nine UPAs, nearly 81,000 patients were seen in the first three weeks of May — more than 17,000 of them presenting respiratory symptoms, roughly one in every five people who walked through the doors.
The triage system is holding its priorities. Critical patients are still seen immediately. But those classified as minor cases are waiting: green-flagged patients average 109 minutes before a doctor sees them, blue-flagged patients around 86. These aren't catastrophic numbers, but they're long enough to feel heavy when you're feverish and uncomfortable.
To ease the pressure, health authorities are steering mild cases toward a remote consultation line — 3350-9000 — available to patients over five years old with minor symptoms on weekdays and weekends. The message is deliberate: if a phone call can help you, stay home and let the UPAs focus on those who need to be there in person.
The city is also maintaining flu vaccination at 109 health facilities, a preventive measure aimed at reducing future demand on those same waiting rooms.
Residents are reminded of the basics that still matter: frequent handwashing, covering coughs and sneezes, keeping homes ventilated even in the cold. And the warning signs that should not be ignored — fever lasting more than three days, difficulty breathing, confusion, severe dehydration — remain the threshold for returning to emergency care without hesitation.
For now, the system is managing. But the wait times tell the honest story: winter has arrived, and the city is carrying its weight.
The cold has returned to Curitiba, and with it, the emergency rooms are filling again. In the first three weeks of May, the city's nine urgent care units—known locally as UPAs—processed nearly 81,000 patients. Of those, more than 17,000 came in coughing, wheezing, struggling to breathe. That's one in five people walking through the doors, all with something wrong in their lungs or throat.
The surge is real enough that it's begun to reshape how the system moves. The sickest patients—those classified as critical—still get seen immediately. The triage system works. But everyone else waits. A patient flagged as green, meaning their condition is considered minor, now spends an average of 109 minutes in the waiting area before a doctor sees them. Those marked blue, not urgent at all, wait 86 minutes on average. These aren't catastrophic delays, but they're long enough to matter when you're feverish and uncomfortable, watching the clock.
The city's health authorities understand the pressure. They've begun steering people away from the emergency units for anything mild. There's a phone line—3350-9000—that handles remote consultations for patients over five years old with minor symptoms. It operates weekdays from 7 a.m. to 10 p.m., weekends from 8 a.m. to 8 p.m. The message is clear: if you can be helped over the phone, stay home. Let the UPAs focus on the people who truly need a physical examination.
The city has also kept its flu vaccination program running at 109 health facilities, targeting the groups most vulnerable to severe respiratory illness. It's a preventive measure, a way to reduce the number of people who will end up in those waiting rooms in the first place.
What complicates things is that respiratory illness in May can mean several different things. A cold—caused by viruses like rhinovirus—brings runny nose and sore throat but usually clears in two to four days without fever. Influenza is harsher: sudden high fever, body aches, malaise, and recovery takes about a week, though exhaustion lingers. COVID-19 ranges from mild to severe, with fever, cough, and fatigue as common markers, but shortness of breath is the red flag that demands immediate medical attention. Allergic rhinitis causes sneezing and throat irritation without fever. Sinusitis inflames the cavities around the nose, creating facial pain and intense nasal congestion, often chronic rather than acute.
The city's guidance is straightforward: wash your hands frequently with soap and water or use 70 percent alcohol gel. Cover your nose and mouth when you cough or sneeze. Keep your home ventilated, even on cold days. These are old lessons, but they work. And if a fever persists beyond three days, if you can't catch your breath, if you feel confused or severely dehydrated, go back to the hospital. Don't wait. Don't guess.
For now, Curitiba's health system is holding. The emergency units aren't overwhelmed—they're managing. But the wait times tell the story: the cold season has arrived, and the city is feeling the weight of it.

La Conversación del Hearth Otra perspectiva de la historia
Why does May specifically bring this surge? Is it just the cold weather, or is there something else happening?
Cold weather drives people indoors, increases transmission of respiratory viruses, and makes existing conditions worse. May in Curitiba is autumn turning toward winter. The temperature drops, humidity changes, and suddenly everyone's breathing the same recycled air.
So the 21 percent figure—that's not unusual for this time of year?
It's seasonal, yes. But the absolute numbers matter. Nearly 81,000 patients in three weeks means the system is at a certain capacity. When one in five of them has respiratory symptoms, the math becomes visible in those waiting rooms.
The city is pushing people toward phone consultations. Does that actually work, or does it just hide the problem?
It works for the cases it's designed for—mild symptoms that don't need imaging or a physical exam. But it only works if people actually use it. Some will still come to the UPA because they're worried, or because they don't trust a phone call, or because they don't know the number exists.
What about the people waiting 109 minutes? Are they being harmed by that wait?
Not usually. If you're classified green—minor urgency—you're not in danger. But 109 minutes is a long time to sit with a fever. It's uncomfortable. It's frustrating. And it means the system is stretched.
Is there a point where this breaks? Where the UPAs can't handle it anymore?
Yes. If respiratory cases jumped to 40 or 50 percent of total volume, or if critical cases started backing up, that would signal real strain. Right now, the system is managing by redirecting the mild cases. That's the pressure valve working.
