Ivermectin treatment was administered every 3 months over a 1-year period (
April 1993-April 1994) to the whole eligible population of a village in Sou
th Cameroon where both Ascaris lumbricoides and Trichuris trichiura were hy
per-endemic. A parasitological stool examination was performed before each
treatment. Thirty children, aged 5-15 years, were not only found egg-positi
ve for A. lumbricoides and/or T. trichiura before the first treatment but w
ere also each treated and examined in each treatment round. Among these chi
ldren, the intensity of infection with A. lumbricoides decreased significan
tly following the first treatment but thereafter remained steady. In contra
st, the repeated ivermectin treatments had no significant impact on the int
ensity of the T. trichiura infections or on the prevalence of infection wit
h T. trichiura or A. lumbricoides among the 30 children.
