H1N1 swine flu symptoms are very similar to the symptoms of seasonal flu. Fortunately, they are typically pretty mild and do not cause significant complications. So what are the H1N1 swine flu symptoms?

Unlike the seasonal flu, many people have also reported symptoms of vomiting and diarrhea. These symptoms can occur with the seasonal flu virus, but are uncommon and more often occur in children.

Because the swine flu is so widespread, you could have it even if you have not traveled recently. If you have severe symptoms or are at high risk of complications, contact your healthcare provider.

If you are having difficulty breathing, experiencing confusion or extreme weakness, seek medical attention right away.
