Colds and flu are viruses that can affect people at any time of year, but the peak time for them is usually between December and February.

 The Center for Disease Control says over the past 40 years, the month where the flu tends to strike the most people is February. Dr. Michale Garko says it isn't just the flu we need to be aware of.

Flu cases are on the rise in both Oklahoma and Kansas, so it's a good time to take precautions against it and other illnesses. Steps anyone can take to help reduce the spread of these viruses is to wash your hands, cover your cough, stay home when you're sick, and make sure you are up on vaccines. To help keep your immune system in shape, eat a healthy diet, be physically active, get enough sleep, and avoid alcohol.
