甲流英語作文:預防流感,從我做起1500字
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。

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.

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。

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.
