A survey of 308,101 schoolchildren conducted in 10 of 11 states in Peninsular Malaysia revealed that 10.7% have Pediculus humanus capitis infestation. The results of treatment with 1%, 2% and 5% DDT in coconut oil in 374 cases reveal cure rates of 3.5%, 15.8% and 51.3%, respectively, suggesting that the head louse has probably developed resistance to this insecticide in Malaysia.
在马来西亚半岛11个州中的10个州对308,101名学童进行的一项调查显示，10.7%的儿童感染头虱。对374例使用1%、2%和5%滴滴涕（DDT）与椰子油混合制剂治疗的结果显示，治愈率分别为3.5%、15.8%和51.3%，这表明马来西亚的头虱可能已对这种杀虫剂产生抗药性。
