Flu Season Tips

What to Know About the 2026-27 Flu Season

In the United States, the influenza (flu) season lasts from October through May, with peak flu activity between December and March. 

The U.S. Centers for Disease Control and Prevention (CDC) estimates that the flu caused between 9.4 million and 51 million illnesses annually between 2010 and 2025. 

Since flu, cold and COVID-19 symptoms can overlap, getting tested can help you know what you’re dealing with. What’s more, flu season in the Southern Hemisphere often indicates what’s to come in the United States. 

The 2026 season was notably milder than 2025’s record-breaking outbreak, with case counts about half as high. However, experts caution that a mild start doesn’t guarantee a mild finish, so vaccination remains the most effective way to prevent flu, especially severe disease and hospitalization. 

Ahead of the 2026-27 flu season, health officials have updated all three virus components of the seasonal flu vaccine, the broadest overhaul in recent years. The change specifically targets an influenza A (H3N2) strain, known as subclade K, which emerged in 2025 and did not closely match the prior vaccine formulation. The updated vaccine protects against influenza A (H1N1), influenza A (H3N2) and influenza B/Victoria lineage viruses. 

How to Stay Healthy 

The flu can cause serious complications for people of any age, but children and older adults are especially vulnerable. Consider these tips to help keep your household healthy this flu season: 

• Get the flu vaccine. It’s the best way to protect yourself from the flu. The CDC recommends that everyone 6 months and older get vaccinated each year. 
• Wash your hands often. Use soap and warm water to remove germs. If that’s not available, use an alcohol-based hand sanitizer. 
• Cover your coughs and sneezes. Use a tissue or your elbow and throw tissues away right after using them. 
• Get enough sleep. Aim for seven to nine hours of quality rest each night to help your immune system stay strong. 
• Stay active. Regular exercise can boost your overall health and help your body fight off infections. 
• Eat well and stay hydrated. A balanced diet with whole grains, lean proteins, fruits, vegetables, and fiber supports your immune system, and drinking enough water keeps your body functioning at its best. 
• Keep your distance from people who are sick.  If you do get the flu, stay home when you’re feeling unwell. 
• Experts recommend getting vaccinated against the flu by the end of October/mid-November, so don’t delay getting your shot. Contact your doctor today to learn more about vaccines.
