We assessed the prevalence of head louse infestation and the effectiveness of 1% permethrin against head lice in Kosovar refugees. A currently infested case was defined as a person with observable crawling lice (adults or nymphs) or a person with nits on the hair shaft within a quarter-inch of the scalp. Of the 1,051 refugees screened upon arrival in the United States, 107 (10%) were infested. Crawling lice (adults or nymphs) were observed on 62 (6%) of the individuals examined. Refugees with crawling lice were treated with a pediculicide containing 1% permethrin. Of these, 57 were reexamined the next day. Twenty of the 57 individuals were reexamined 7 days after treatment. No crawling lice were found on any of the refugees examined after treatment. We conclude that 1% permethrin treatment was effective in louse control in this refugee population.
