Question

Hi,
flu symptoms are usually more severe than cold symptoms and come on quickly. Symptoms of flu include sore throat, fever, headache, muscle aches and soreness, congestion, and cough. Swine flu in particular is also associated with vomiting and diarrhea.
A common complication of the flu is pneumonia, particularly in the young, elderly, or people with lung or heart problems. Shortness of breath is another complication of this.
Prevention
wash hands often; avoid close contact with anyone who has flu symptoms; get the annual flu vaccine.
