What are swine flu symptoms?

Symptoms of H1N1 swine flu are like regular flu simptoms  and include fever, cough, , runny nose, body aches, headache , chills, and fatigue. Many people with swine flu have had diarrhea and vomiting.  But these symptoms can also be caused by many other conditions.
That means that you and your doctor can't know, just based on your symptoms, if you've got swine flu. Health care professionals may offer a rapid flu test, although a negative result doesn't mean you don't have the flu. The accuracy of the test depends on the quality of the manufacturer’s test, the sample collection method, and how much virus a person is shedding at the time of testing.
Like seasonal flu, pandemic swine flu can cause neurologic symptoms in children. These events are rare, but, as cases associated with seasonal flu have shown, they can be very severe and often fatal. Symptoms include seizures or changes in mental status (confusion or sudden cognitive or behavioral changes). It's not clear why these symptoms occur, although they may be caused by Reye's syndrome. Reye's syndrome usually occurs in children with a viral illness who have taken aspirin -- something that should always be avoided.
Only lab tests can definitively show whether you've got swine flu. State health departments can do these tests. During the peak of the pandemic, these tests were reserved for patients with severe flu symptoms.
