Studies on Human Head Louse Pediculus humanus capitis (Anoplura) Infestation (Case Report)
Thirteen cases of the human head louse infestation (Pediculus humanus capitis De Geer, 1778) in Okayama City were reported. All the patients were found in ages between 2 and 35, and the highest incidence ranged in the age group of 10 years old and younger. The sex ratio of the patients was higher in female than in male. The patients were recognized more often in the early winter months of November and December. Adults and/or eggs (nits) of Pediculus louse were localized on hair of all the patients. For the patients Eurax (Crotamiton) cream containing 3% benzyl benzoate was used and the results were remarkable.
