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.

The study

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.

The results

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."

The takeaway

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.

I mean, I know it was my choice to read through, but I genuinely believed you would probably have something useful to talk about. All I hear is a bunch of complaining about something that you could possibly fix if you weren't too busy seeking attention.

    Hi My name is Rebecca.i just want to share my experience with the world on how i got my love back and saved my marriage… I was married for 7 years with 4 kids and we lived happily until things started getting ugly and we had a fights and arguments almost every time… it got worse at a point that he filed for divorce… I tried my best to make him change his mind & stay with me cause i loved him with all my heart and didn’t want to loose him but everything just didn’t work out… he moved out of the house and still went ahead to file for divorce… I pleaded and tried everything but still nothing worked. The breakthrough came when someone introduced me to this wonderful, great spell caster Dr Zuma, who eventually helped me out… I have never been a fan of things like this but just decided to try reluctantly cause I was desperate and left with no choice… He did special prayers and cast a love spell on him. Within 24hours he called me and was sorry for all the emotional trauma he had cost me, moved back to the house and we continue to live happily, the kids are happy too and we are expecting our fourth child… I have introduced him to a lot of couples with problems across the world and they have had good news… Just thought I should share my experience cause I strongly believe someone out there needs it… You can contact him on spiritualherbalisthealing@gmail.com whatsapp +15068001647
