Can a child( or adult for that matter) have the flu/swine flu with all the symptoms WITHOUT having a fever? If so, how long are they contagious? How long does the swine flu last?
Swine Flu Symptoms
According to the CDC, like seasonal flu, symptoms of swine flu infections can include:
Signs of a more serious swine flu infection might include pneumonia and respiratory failure.
If your child has symptoms of swine flu, you should avoid other people and call your pediatrician who might do a rapid flu test to see if he has an influenza A infection. Further testing can then be done to see if it is a swine flu infection. (Samples can be sent to local and state health departments and the CDC for confirmation of swine flu, especially if a child is in the hospital.)
