What exactly is the swine flu?

Swine influenza is a known cause of flu in pigs. But once in a while, through mutations, it can acquire the ability to attack humans. According to Charles Erickson, cough etiquette is the critical thing. You should be cautious about your own behavior covering your mouth and nose when you cough or sneeze in public. As with other flu viruses, people can sometimes become infected by touching something with a virus on it a desktop, a doorknob then touching their eyes, nose or mouth, according to experts at the U.S. Centers for Disease Control and Prevention. You cannot get swine flu from eating pork.The effectiveness of face masks is still "controversial," Ericsson said. If a true pandemic emerges, then mask wearing "might not be a bad idea" in crowded environments, he said. "And if you are ill you should certainly stay home from work" to avoid spreading the illness, he added.
