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.

    Am Karen Lola from Scotland. I was having serious relationship problems with my boyfriend and it had resulted in him moving out to his friend’s apartment. Everything got worse because he started going to bars and strip clubs frequently with his friend, getting drunk and passing out. He always threatens me on phone whenever I call him because of all the bad advises that his friend has given him. I really love him and we had been dating for 8 years which gave us a beautiful daughter. I had also lost a lot of money on therapists until I was introduced to Dr.Unity by a friend whom he helped to marry her childhood boyfriend; this gave me total confidence and strength to get him back. I did all he asked and after 48 hours my boyfriend called me and rushed back home, things just changed between us emotionally. He has a job and stopped drinking and keeping irrelevant friends. It’s a miracle I never believed was possible because I had lost all hope until I found Dr.Unity. So that’s why I promised to share my testimony all over the universe. All thanks goes to Dr.Unity for the excessive work that he has done for me. Below is the email address in situation you are undergoing a heart break, and I assure you that as he has done mine for me, he will definitely help you too. Email him at: Unityspelltemple@gmail.com ,you can also call or Add him on Whatsapp: +2348071622464·

    My husband left me to be with another woman. and wanted him back. i was jealous and it made us argue all the time until he vanished away, I was desperate to get him back, I wasted so much time and money on getting my lover back after I have tried almost all possibilities to have him back and nothing worked. I became lonely for 2 years. To make it short, I found a spell caster Dr Unity by accident. I don’t know how I found him and i cant remember. But, when I first saw the good testimonies about his wonderful work and after reading the Testimonials, I decided I had to try and give it one last shot. After the spells, a miracle happened, my husband came home. it was awesome, anyone who needs help, should email, Unityspelltemple@gmail.com or you can also visit his website:http://unityspelltemple.yolasite.com ,He is the best. whoever need a spell caster that will work for you and bring back your lover should contact Dr.Unity.
