The good news is this: Although swine flu is highly contagious, the World Health Organization says it generally causes "very mild illness" in healthy people.
But there are ways to prevent the flu from spreading, mainly by washing your hands.
If doctors sound like your mom, who keeps bugging you to wash your hands before you eat, there's a reason.
"Whenever you're contaminated by touching things that other people have touched desks or tabletops in the lunchroom you really should wash your hands before eating or drinking or touching your face," said Dr. Philip Tierno, director of clinical microbiology and immunology at New York University's Langone Medical Center. Eighty percent of all infections are spread when you touch germs and then touch your mouth, eyes and nose.
And the flu bug is a survivor. The swine-flu virus can survive on a desk or a doorknob for two to eight hours after it lands there, according to the U.S. Centers for Disease Control and Prevention. That's why hand-washing and disinfecting lunchroom tables, doorknobs and gym equipment is so important.
However, many kids are bound to get swine flu this year. So here's some advice from the CDC: If you think you're sick, stay home. The symptoms of swine flu include fever, cough, sore throat, runny or stuffy nose, body aches, headache, chills and fatigue. A significant number of those already afflicted also have reported diarrhea and vomiting.
Wash your hands frequently with soap and water. But not so fast, kiddo! You're supposed to wash for 20 seconds so sing the "Happy Birthday" song to yourself twice to make sure you've washed long enough. And don't just wash your palms. Rub soap on the backs of your hands, between your fingers and underneath your fingernails. Antibacterial soap or plain soap? There's no need to use antibacterial soap the water washes away the flu virus.
HAND SANITIZER 101:
If soap and water are not available, use hand-sanitizing gel. Pick a brand that contains at least 62percent alcohol, said Tierno, the microbiologist. Most important: Wash hands or use hand sanitizer right before you eat lunch because when you pick up your sandwich, you could spread germs from your hands to your food and then to your mouth.
COUGH AND SNEEZE ETIQUETTE:
Cough or sneeze into a tissue and then wash or sanitize your hands. If you don't have a tissue handy, sneeze or cough into the crook of your arm or your shoulder so your germs don't spread through the air. Don't cough or sneeze into your hands! If you do, wash immediately.
Avoid touching your eyes, nose and mouth. That's the fastest way to spread germs into your body.
The danger from the water fountain isn't from kids putting their mouths on the fountain because the stream of water washes away germs. The most contaminated part of the fountain is the handle or button you push to turn it on, say experts. But to be safe during the swine- flu pandemic, it's probably best to send kids to school with their own water bottles. What about handrails, doorknobs or keyboards? It's not practical to ask kids not to touch any surfaces at school. Instead, experts recommend that kids carry their own container of hand sanitizer and use it frequently.
