Influenza

Influenza (flu) is a contagious respiratory illness caused by influenza viruses. It spreads easily, especially during flu season, and can range from mild to severe.

Flu is different from the common cold — it often starts suddenly and causes more whole-body symptoms like fever and body aches. Testing can help confirm influenza when symptoms are unclear or treatment timing matters.

NeuMed offers walk-in cold and flu evaluation with rapid testing options at Houston-area clinics when clinically appropriate.

Flu symptoms often appear suddenly. Common signs include:

• Fever or feeling feverish/chills
• Body aches and fatigue
• Headache
• Cough
• Sore throat
• Runny or stuffy nose
• Vomiting or diarrhea (more common in children)

Flu spreads through respiratory droplets when an infected person coughs, sneezes, or talks. You can also pick up the virus by touching contaminated surfaces and then your face.

Flu season in the U.S. typically peaks between fall and spring. Vaccination is the best preventive measure, though breakthrough infections can still occur.

Flu can overlap with other respiratory illnesses — including COVID-19, RSV, and strep — which is why testing may be recommended when diagnosis affects treatment.

Diagnosis is based on symptoms, exam, and sometimes rapid testing. A provider reviews your history and may perform a rapid influenza test during your visit when clinically appropriate.

Rapid flu tests use a nasal or throat swab. Results are often available during the same appointment, though timing varies. Negative rapid tests do not always rule out flu — your provider interprets results in context.

COVID-19 testing may also be considered when symptoms overlap, since both can cause fever, cough, and fatigue.

Most people recover with rest, fluids, and over-the-counter symptom relief. Stay home while contagious to protect others.

Antiviral medications may be prescribed for flu when started early and clinically appropriate — especially for higher-risk patients. They work best when begun within the first day or two of symptoms.

Antibiotics do not treat flu (a viral illness). They are used only if a bacterial complication is diagnosed.

Children and flu: Kids can become dehydrated quickly. Monitor fluid intake and seek care for breathing difficulty, signs of dehydration, or if your child appears very ill. NeuMed provides pediatric urgent care for children 6 months and older.

Urgent care is appropriate for flu-like symptoms that need evaluation but are not life-threatening — especially when you want testing, symptom relief guidance, or antiviral consideration.

NeuMed clinics offer walk-in cold and flu care seven days a week with rapid testing when appropriate. Save your spot online or walk in.

Flu shots are also available during flu season — ask about vaccination when you visit.
