Abstract
The infestation with the human obligate ectoparasite Pediculus humanus capitis De Geer is a
common public health problem affecting mainly schoolchildren worldwide. The aim
of the present study was to investigate the infestation levels of head lice in
elementary schools from Buenos Aires
with resistant levels to permethrin >100. A total of 1,856 children aged
3-13 years old from eight selected elementary schools were examined for head
lice. Pediculosis was observed in all the studied schools. The overall
infestation rate was 29.7%. Girls were statistically significant more infested
than boys, with infestation rate values of 36.1% and 26.7%; respectively (P<0.0001). Only 42 of the infested
girls (12%) and 23 of the infested boys (11.4%) had >10 lice on their hair.
The proportions of infested children both girls and boys- in each age group
were not found to differ significantly from one another. The infestation rate
among schools varied from 19.12% to 42.74%. This indicated that pediculosis is
relatively common in elementary schools from Buenos Aires and those levels are of epidemic
importance. The differences of pediculosis among the studied schools could be
explained by the different control strategies applied by parents or advisors to
eradicate head lice.
