We examined the prevalence and intensity of Ascaris lumbricoides and Trichuris trichiura infections among 240 fecal specimens, and the association between selected socio-demographic variables and infection for 62 households.
trichiura infection included: number of children 6-14 years old (p=0.01, p=0.04, respectively), ownership of a latrine (p=0.04, p=0.03, respectively) and coinfection with either helminth (p=0.001, p=0.001, respectively).
We studied the prevalence and intensity of Ascaris and Trichuris infections in individuals of all ages in four communities under UNIR, and identified variables that have an important association with such infections.

Small children aged 3 to 9 years are more often infected than adults and are more likely to develop heavy worm burdens, since they play with contaminated soil and thus transfer embryonated eggs to their mouths by their fingers.
In severe infections, Trichuris may infect the entire colon, including the rectum and appendix; it is rarely found in the terminal ileum.
Once established, Trichuris may live in the bowel for several years, but because of its firm attachment to the intestinal mucosa the infection may be totally unsuspected and no investigation may be made unless the patient also harbors other parasites, such as the freely moving Ascaris.

Background: The whipworm, ie, Trichuris trichiura, is notable for its small size compared to Ascaris lumbricoides.
Principally a problem in tropical Asia and, to a lesser degree, in Africa and South America, a lack of a tissue migration phase and a relative lack of symptoms characterize whipworm infection.
