A study was conducted to determine the prevalence rate of Ascaris lumbricoides, Trichuris trichura and hookworm (Ancyclostoma duodenale and Necator americanus) on grades I-IV morning pupils (8-10 years old) in the Almanza Elementary School in Las Pinas. The prevalence rate was also determined according to sex. Collection of stool samples was done from July to December 1997. All stool samples were prepared using the Direct Fecal Smear Method and examined under the compound light microscope. Results showed that A. lumbricoides had a higher overall prevalence rate than T. trichura in both sexes at 18.1%. Trichuris had an overall prevalence rate of 13.8%. No hookworm was seen on the stool samples of the children. It was also determined that both parasites had higher prevalence rates in males than in females at 20% for A. lumbricoides and 16% for T. trichura. In females, 15.9% were infected with A. lumbricoides and 11.4% were infected with T. trichura. Mixed infection had an overall prevalence rate of 8.5%. The prevalence rate for mixed infection in males was still greater at 10% compared to females at 6.85.
