Flu Prevention

A flu shot can cut your chance of getting sick by about 40–60% in a typical season. That’s a big drop in risk and a simple place to start. Below are clear, practical steps you can use right away to lower your odds of catching—or spreading—the flu.

Get the right vaccine and know the timing

Get vaccinated every year, ideally before flu activity peaks in your area. If you’re 65 or older, ask for a high-dose or adjuvanted vaccine made to boost protection. Pregnant people, young children, people with chronic conditions, and caregivers should get vaccinated too—these groups face higher risk of complications. If you miss early season shots, get vaccinated later rather than not at all; the season can extend for months.

Keep proof of vaccination handy if your workplace or school asks for it. Pharmacies, primary care clinics, and many community centers offer flu shots without an appointment.

Daily habits that really work

Wash your hands for at least 20 seconds with soap and warm water. When soap and water aren’t available, use an alcohol-based hand sanitizer with at least 60% alcohol. Avoid touching your eyes, nose, and mouth—flu viruses enter through these routes. If you cough or sneeze, use a tissue and toss it, or cough into your elbow.

Wear a mask in crowded indoor places during high flu activity, especially if you or someone you care for is high-risk. A well-fitting surgical mask or N95/KN95 provides the best protection. Also, improve indoor air: open windows when possible, run a HEPA air cleaner, and avoid crowded poorly ventilated spaces.

Keep humidity in living spaces around 40–60%. Dry air lets viruses stay infectious longer and dries mucous membranes that help block infection. A basic humidifier in winter can help, but don’t over-humidify.

Boost basic defenses: sleep 7–9 hours, eat a balanced diet, stay hydrated, and manage stress. These habits don’t stop the flu on their own but make your immune system work better.

If someone in your household gets sick, separate them when possible, use separate towels and utensils, clean high-touch surfaces daily with household disinfectant, and wash bedding and clothes frequently.

Antiviral medicines like oseltamivir work best if started within 48 hours of symptoms and can reduce severity and complications for people at higher risk. Talk to your doctor quickly if you or a loved one has severe symptoms or belongs to a high-risk group.

Stay home if you’re sick. You’re contagious one day before symptoms start and about five to seven days after. For children and people with weakened immune systems, the contagious period can be longer. A practical rule: stay home until you’ve been fever-free for 24 hours without fever-reducing medicine.
