Galveston County Daily News, Dec. 10, 2008 In their weekly Keeping Kids Healthy column, Drs. Sally Robinson and Keith Bly advise readers to get flu shots for the entire family. They also remind readers about the difference between the flu and a viral or bacterial infection. "A high fever, headache, sore throat, cough, congestion, chest discomfort and muscle aches. You probably know all too well that these are the symptoms of influenza. Many parents think vomiting and diarrhea signal the flu. These are usually signs of a bacterial or viral infection of the stomach and intestines known as gastroenteritis."
