An outbreak of head lice infestation (pediculosis) occurred in elementary school children in Barrow County, Georgia, in January 1974. An investigation was initiated to define the magnitude of the outbreak, determine factors that contribute to transmission, and disseminate information on control. All elementary school children in the county were examined for head lice and answered a questionnaire. Fifty-three (3%) of 1,783 white pupils were infested, but none of the 500 black pupils was infested. Distribution of infestation in the white pupils was influenced by grade, bed-sharing, socioeconomic status, infestation of other family members, crowding in the home, and family size; distribution was not influenced by hair length or the sex of the pupil. Recommendations for control based on the results of the investigation included procedures for identifying and processing cases, distributing free pediculicides, continuing surveillance, educating school personnel and parents on how to control the parasite.
1974年1月，佐治亚州巴罗县的小学生中爆发了头虱感染（头虱病）。开展了一项调查，以确定疫情的规模，确定促成传播的因素，并传播防治信息。对该县所有小学生进行了头虱检查并回答了一份问卷。1783名白人学生中有53名（3%）受到感染，但500名黑人学生中无人感染。白人学生的感染分布受年级、同床睡觉、社会经济地位、其他家庭成员的感染情况、家中拥挤程度和家庭规模的影响；分布不受头发长度或学生性别的影响。根据调查结果提出的防治建议包括识别和处理病例的程序、分发免费的灭虱剂、持续监测、教育学校工作人员和家长如何控制这种寄生虫。
