Hand sanitizer doesn't help in schools
School children get low marks when it comes to spreading germs, often sharing bugs with their classmates. So scientists wondered if putting hand sanitizers into elementary school classrooms would lead to fewer absences.
Researchers in New Zealand set out to discover if using alcohol-based hand sanitizers, in addition to regular hand washing, would cut back on absentee rates in schools.
They recruited 68 primary schools, and all students were given a half-hour hygiene lesson. They then assigned half of the schools to a control group where children washed their hands with soap and water. The schools in the intervention group did the same, but were also asked to use classroom hand sanitizers when they coughed or sneezed, and before meals.
When children missed school, calls were made to find out if the child was sick. The research team checked-in with the caregivers of more than 2,400 children, keeping track of the type and length of their illnesses during 20 weeks of school.
Absentee rates between the two groups were virtually the same, the study authors found.
"These findings suggest that, in high-income countries where clean water for hand washing is readily available, putting resources into extra hand hygiene by providing hand sanitizer in classrooms may not be an effective way to break the child-to-child transmission of infectious diseases," an accompanying editorial in the journal concluded.
An unexpected flu epidemic during the course of the study may have affected the findings. Heightened awareness about the benefits of clean hands during the epidemic may have led to more hand washing overall, making it more difficult to see if hand sanitizers gave added benefit, says Dr. Jennifer Shu, a pediatrician in Atlanta who was not involved with the study.
But the study authors say that the impact of hand sanitizer would be particularly important during an influenza pandemic, and they found "providing hand sanitizer was not an effective mechanism for reducing illness absence."
So what is the takeaway message for schools and parents? The Centers for Disease Control and Prevention says it's best to have children wash their hands with soap and water. If a sink is not available, hand sanitizers with an alcohol concentration of at least 60% are a good second choice.
The bottom line, do what it takes to rub those germs away.

There's definately a lot to learn about this subject. I love all the points you have made.
I've been browsing on-line greater than 3 hours these days, but I never discovered any attention-grabbing article like yours. It is lovely price enough for me. In my opinion, if all site owners and bloggers made excellent content as you probably did, the internet might be much more helpful than ever before.
