Flu Season in Florida: Why It Hits Different Here

Something that catches a lot of my Orlando patients off guard: you can absolutely get the flu in August.

Last summer, a patient came in convinced she had heat exhaustion. Tired, body aching, running 101 degrees. She'd been careful about the sun, drinking plenty of water, couldn't figure out what was wrong. It was influenza. In August. She'd never even considered it.

Florida doesn't follow the national flu calendar. Most of the country has one flu season — November through March, roughly. Here in Central Florida, we have two. There's a summer surge that runs through June, July, and into September, and then the familiar winter wave picks back up in late fall. The reason isn't mysterious: when it's 95 degrees outside, everyone retreats into air conditioning. Schools are back in session by mid-August. Families are packed into theme parks year-round. Grocery stores, waiting rooms, and movie theaters become the places where this virus travels — efficiently, quietly, constantly.

That double-season reality changes when you should get vaccinated. The standard advice you'll hear everywhere is "get your flu shot in September or October." That timing makes sense in Ohio. In Florida, if you wait until October, you've already missed half the summer season. I tell my patients: get vaccinated in August, especially if you have kids starting school. You can come to either of our offices for that — no big production, just call ahead.

Another thing that trips people up here is confusing the flu with allergies or a summer cold. Central Florida has year-round pollen and mold. Oak, cedar, grass — they overlap and never really give you a clean break. Patients come in sneezing, congested, run-down, and assume it's just their allergies flaring up again. Here's a practical rule I give people: allergies don't cause fevers. They don't make your muscles feel like concrete. If you feel like you got hit by a truck — full-body ache, chills, fever over 100 degrees — that's not pollen. That's something else, and it needs a different response.

I also want to speak directly to something I hear from a lot of my Hispanic patients: "I'll just ride it out" or "it's not worth missing work." I understand that calculation. But the flu in adults — especially anyone managing diabetes, high blood pressure, or asthma, even when those conditions are well controlled — can turn serious faster than people expect. Pneumonia is a real complication, and it doesn't always announce itself clearly before it's already a problem.

Here's what you can do right now, this week: schedule your flu shot if you haven't. Get your kids vaccinated too — children are extraordinarily efficient at carrying this virus home to everyone else. If you're 65 or older or have a chronic illness, ask us specifically about the high-dose vaccine. Keep a thermometer at home and know your normal temperature, because a reading of 101.5°F means something different depending on your baseline.

If you do get sick, antivirals like oseltamivir (Tamiflu) work best within the first 48 hours of symptoms. A lot of people wait to see if they'll feel better on their own, then find out too late that earlier treatment could have cut their illness in half. Call us as soon as you start feeling bad — don't wait two days to decide.

When should you actually come in? Come to our office if your fever has been above 101°F for more than two days, if you can't keep fluids down, or if you have a chronic condition and you're getting worse rather than better. Go to the emergency room — not urgent care, the ER — if you have trouble breathing, chest tightness, confusion, or your lips or fingernails look bluish. Those are not "let's monitor this at home" symptoms.

For deeper reading on flu prevention and what to watch for this season, our health resource partner VitaGuia (vitaguia.com) has solid guides in both English and Spanish.

If you're in the Lake Nona or Lancaster area and haven't gotten your shot yet, come see us. We're a small practice on purpose. You get to actually talk to Dr. Arevalo, not whoever happened to be working the urgent care shift that morning. We know our patients — which ones need closer watching during flu season, which kids tend to bring things home, which families have someone high-risk at home. That kind of continuity is what primary care is supposed to be. We'd love to be that for your family.
