Head lice infestations have become a problem in school children in Sacramento County. An open study was conducted to determine how widespread head lice infestations were among preschool and elementary school children in Sacramento County and to see how effective a newly marked ever-the-counter pediculicide containing 0.3% pyrethrins synergized by 3.0% piperonyl butoxide was. The public health nurse for this study visited the homes of all reported patients infested with head lice. She verified and provided the pyrethrins-based treatment for 248 children, aged 6 months to 12 years. The children were Caucasian, Mexican-American, black and other ethnic backgrounds and from low, middle and upper income levels. All the patients were successfully treated, and the school children were able to return to their classs in a short time.
头虱感染已成为萨克拉门托县学童面临的一个问题。开展了一项开放性研究，以确定萨克拉门托县学龄前儿童和小学生头虱感染的普遍程度，并观察一种新上市的含0.3%除虫菊酯且由3.0%胡椒基丁醚增效的非处方灭虱药的效果如何。该研究的公共卫生护士走访了所有报告的头虱感染患者的家庭。她核实情况并为248名年龄在6个月至12岁的儿童提供了基于除虫菊酯的治疗。这些儿童有白种人、墨西哥裔美国人、黑人以及其他种族背景，来自低收入、中等收入和高收入水平家庭。所有患者均成功治愈，学童们能够在短时间内重返课堂。
