The flu is without a doubt one of the biggest pains of winter.
Influenza is a viral infection that's especially common in winter.
Most cases are handled simply, but a few can require hospitalization. Flu shots are a good idea for older people or those with compromised immune systems. They're not really necessary for otherwise healthy children. The best thing you can do to prevent the flu is to practice good hygiene and wash your hands regularly. Doctors at UT Southwestern Medical Center at Dallas say it's important to cover your mouth when you cough or sneeze and make sure those around you do the same.
