Now,everyday we can read from the news paper,it's all about swine flu,or pig flu a(H1N1) that already spread out to many country,here is some explaination and tips to prevent it...

What is swine flu?

Like people, pigs can get influenza (flu), but swine flu viruses aren't the same as human flu viruses. Swine flu doesn't often infect people, and the rare human cases that have occurred in the past have mainly affected people who had direct contact with pigs. But the current swine flu outbreak is different. It's caused by a new swine flu virus that has spread from person to person -- and it's happening among people who haven't had any contact with pigs.

What are swine flu symptoms?

Symptoms of swine flu are like regular flu symptoms and include fever, cough, sore throat, body aches, headache, chills, and fatigue. Some people have reported diarrhea and vomiting associated with swine flu. Those symptoms can also be caused by many other conditions, and that means that you and your doctor can't know, just based on your symptoms, if you've got swine flu. It takes a lab test to tell whether it's swine flu or some other condition.
