It's still not too late to get a flu shot. There's been a big increase in flu cases in Pennsylvania in recent weeks.

The following health tip is from the Pa. Department of Health:

Influenza, also known as the flu, is a contagious disease that is caused by the influenza virus. It attacks the respiratory tract in humans (nose, throat, and lungs). The flu is different from a cold. Influenza usually comes on suddenly and may include these symptoms:

• Fever
• Headache
• Tiredness (can be extreme)
• Dry cough
• Sore throat
• Nasal congestion
• Body aches

These symptoms are usually referred to as "flu-like symptoms."

If you think you have the flu, or do get sick, stay home from work or school so that you don’t infect or make others ill.
