The flu (influenza) is a contagious respiratory illness caused by influenza viruses. It can cause mild to severe symptoms and spreads easily — especially during fall and winter.

Flu symptoms often come on suddenly and may include:

• Fever or chills
• Cough or sore throat
• Runny or stuffy nose
• Muscle or body aches
• Fatigue
• Headaches
• Sometimes vomiting or diarrhea (more common in children)

Yes, but your symptoms are likely to be milder and shorter. The vaccine reduces the risk of severe illness, hospitalization, and complications.

If you have mild symptoms (like a cold or allergies), you can usually still get vaccinated. But if you have a fever or more serious illness, it’s best to wait. Reach out via the app if you're unsure.
