丹麦学者对324名年龄在5～14岁的学生进行研究后发现，定期训练这些学生如何正确洗手和/或使用含有酒精的消毒胶可显著减少这些学生因病缺课的概率。分析发现，在为期3个月的研究过程中，这些学会了如何正确洗手的学生因病缺课4天或更长时间的百分比较前一年同时段减少了66％，从无缺课的百分比则增加了20％。这些数据提示，正确的选手即可显著改善学生的健康状况，进而减少他或她们因病缺课的概率。值得重视和借鉴啊！

Kids Taught to Wash Hands in School Avoid Sick Days: Study

Training in hand hygiene and disinfection may be a simple, cheap way to reduce infectious illness

By Robert Preidt

TUESDAY, Aug. 9 (HealthDay News) -- Good knowledge of hand hygiene among students reduces school absenteeism, researchers report.

The study included 324 elementary school students, aged 5 to 14, in Denmark. The children were given a lesson in hand disinfection theory and practice and told to disinfect their hands using ethanol gel three times each school day.

During the three-month study, there was a 66 percent decrease in students who were absent for four or more days and a 20 percent increase in children with zero absences, compared to the previous school year, the investigators found.

"Regular training in [hand washing] and [hand disinfection] would be a simple, low-cost action with very significant impact on reducing infectious illness absence periods among pupils," stated study author and infection preventionist Inge 　Nandrup-Bus, in a news release from the Association for Professionals in Infection Control and Epidemiology.

The study is published in the August issue of the American Journal of Infection Control.
