The flu is an infection caused by a
virus. The virus spreads when a person coughs or sneezes. Flu symptoms may include a
sudden high fever, chills, body aches, sore throat, runny nose, dry cough, and headache.
But people with diabetes who catch the flu may get even more sick. The illness sometimes
leads to pneumonia. Or to a dangerously high blood sugar level. In some cases, you may
need to be in the hospital.
The best way to protect yourself
against the flu is to get the flu vaccine. This won't give you full protection. But it
makes it less likely that you will have the flu for about the next 6 months. You need a
new flu shot each year. Get the flu shot as soon as it is available in your area. Then
you'll be protected before flu season starts. It helps if the people you live with get
flu shots, too.
