Houston Flu Season 2026: When to Get Your Flu Shot and What to Know

When Flu Season Hits Houston

Houston's flu season generally follows the national pattern, with activity beginning to rise in October, peaking between December and February, and tapering off by April. However, Houston's mild winters and high population density can extend transmission windows beyond what other regions experience. It is not unusual for flu cases to spike as late as March in the greater Houston area.

The 2025-2026 flu season has followed this pattern, with activity increasing through the fall and reaching its peak in early 2026. If you have not been vaccinated yet, it is not too late — the flu virus continues to circulate and vaccination provides protection within about two weeks of receiving the shot.

Who Should Get a Flu Shot

The CDC recommends annual flu vaccination for everyone aged 6 months and older, with rare exceptions for those with severe allergies to vaccine components. Vaccination is especially critical for:

• Adults over 65, who face the highest risk of flu-related hospitalization and death
• Children under 5, particularly those under 2
• Pregnant women, at any stage of pregnancy
• People with chronic conditions — asthma, diabetes, heart disease, kidney disease, weakened immune systems
• Healthcare workers and caregivers who interact with vulnerable populations

Even if you are young and healthy, getting vaccinated reduces your chance of transmitting the virus to someone who could be seriously affected.

What to Do If You Get the Flu

If you develop flu symptoms — fever, body aches, chills, fatigue, cough, sore throat, headache — here is how to manage it:

• Stay home. You are contagious from about one day before symptoms appear until five to seven days after they start. Avoid work, school, and public spaces during this window.
• Hydrate aggressively. Fever and sweating deplete fluids rapidly. Drink water, electrolyte beverages, broth, and tea consistently throughout the day.
• Rest. Your immune system works best when your body is resting. Cancel your plans and give yourself permission to recover.
• Manage symptoms. Over-the-counter medications like acetaminophen or ibuprofen can reduce fever and body aches. Decongestants and cough suppressants can ease respiratory symptoms.

When to See a Doctor

Most healthy adults and older children can recover from the flu at home within one to two weeks. However, you should visit a clinic if you experience:

• Difficulty breathing or shortness of breath
• Persistent chest pain or pressure
• Severe dehydration (dizziness upon standing, inability to keep fluids down, dark urine)
• Fever above 103°F that does not respond to medication
• Symptoms that improve and then return with worsened fever or cough (may indicate a secondary infection)
• Any flu symptoms in infants, elderly adults, pregnant women, or immunocompromised individuals

If caught within the first 48 hours, antiviral medications like oseltamivir (Tamiflu) can reduce the duration and severity of the flu. Walk into any Hybrid Health Clinics location for evaluation — no appointment needed.
