Influenza (flu) is a contagious respiratory illness that affects millions of Americans each year. According to the CDC, seasonal flu causes an estimated 9-41 million illnesses, 140,000-710,000 hospitalizations, and 12,000-52,000 deaths annually in the United States. Understanding prevention and treatment options can help you and your family stay healthy.
Flu vs. Cold: Know the Difference
While both are respiratory illnesses, flu symptoms are typically more severe:
- •Sudden onset (flu) vs. gradual onset (cold)
- •High fever (flu) vs. mild/no fever (cold)
- •Severe body aches (flu) vs. mild aches (cold)
- •Extreme fatigue (flu) vs. mild tiredness (cold)
- •Dry cough (flu) vs. productive cough (cold)
- •Headache common (flu) vs. rare (cold)
Prevention: The Flu Vaccine
Annual flu vaccination remains the best protection:
- •Recommended for everyone 6 months and older
- •Best received by end of October, but beneficial any time during flu season
- •Takes about 2 weeks to develop full protection
- •Even if you get flu after vaccination, symptoms are often milder
- •Reduces risk of flu-related hospitalization
The flu vaccine cannot give you the flu. It contains either inactivated virus or no virus at all (recombinant vaccines).
High-Risk Groups
Some people are at higher risk for flu complications:
- •Adults 65 and older
- •Children under 5, especially under 2
- •Pregnant women
- •People with chronic conditions (asthma, diabetes, heart disease)
- •Immunocompromised individuals
- •Nursing home residents
- •American Indians/Alaska Natives
Antiviral Treatment
Antiviral medications can shorten flu duration and reduce severity:
- •Oseltamivir (Tamiflu): Oral medication, most commonly prescribed
- •Zanamivir (Relenza): Inhaled medication
- •Peramivir (Rapivab): IV medication for hospitalized patients
- •Baloxavir (Xofluza): Single-dose oral medication
Antivirals work best when started within 48 hours of symptom onset. If you're high-risk, contact us immediately when symptoms begin.
When to Seek Care
Contact your healthcare provider if:
- •You're in a high-risk group with flu symptoms
- •Symptoms are severe or worsening

Home Care Tips
If you have mild flu and aren't high-risk:
- •Stay home to avoid spreading illness (usually 24 hours after fever resolves)
