预防流感，从我做起
Swine flu has yet to escalate into a global pandemic but here‘s what to do if it does 5 Ways to Protect Yourself (and Others) from Swine Flu Experts say that the steps you should take to shield yourself from swine flu are not much different than those you might take to ward off seasonal flu。
1. Don‘t touch your face
Above all keep your hands away from your eyes mouth and nose all of which serve as pathways for the virus to enter your respiratory tract says Allison Aiello an epidemiologist at the University of Michigan School of Public Health in Ann Arbor。
2. Wash your hands
If you must touch your face scrub your hands getting under the fingernails and inside all crevices for 20 to 30 seconds with hot soap and water beforehand Aiello says. “In addition to dislodging dirt that may contain virus particles soaps contain surfactants [the primary components of detergents] which can damage the lipid [fat] protecting virus particles“ she explains. Soap should therefore be effective against all flu viruses。
3. Use a hand sanitizer
No sink nearby? Then use an alcohol-based hand sanitizer Aiello advises. About a quarter-size spot rubbed all over the hands until the sanitizer evaporates (usually 10 to 15 seconds)， should do it. Alcohol can inactivate viruses by destroying the structure of their proteins she notes。
4. Cover your nose and mouth
When someone sneezes or coughs liquid droplets packing flu viruses can travel as far as three feet (one meter) through the air and descend on your nose or mouth so it‘s best to maintain at least an arm‘s-length distance when talking to someone who shows signs of infection says Louise Dembry director of epidemiology at Yale–New Haven Hospital in Connecticut. And to protect others cover your mo.
