Hand sanitizer has become ubiquitous after the outbreak of the novel H1N1 flu virus. But what are its special powers? Does it really protect from viruses? And what's the best way to use it?

When it comes to choosing a hand sanitizer, the Centers for Disease Control and Prevention recommends the ones with alcohol for protecting against the H1N1 flu. The optimum proportion is 60 to 95 percent alcohol, according to this CDC chart showing the relative effectiveness of different types of sanitizers.

Dr. Anne Schuchat, director of the National Center for Immunization and Respiratory Diseases, said in a recent briefing that people should wash their hands often with soap and water or alcohol-based hand sanitizers to combat the flu.

"We are beginning to see some declines in influenza activity, but there is still a lot of influenza everywhere," she said.

The CDC said that according to some estimates, up to 80 percent of all infections get spread by hands.

    No hand sanitizer will kill a virus. but I found a hand sanitizer which is acohol free and protects from germs for 8 hours, unlike regular alcohol sanitizers which last about 18 seconds. the link is which are offering a free trial currently. worth alook.
