Estimated that more than 1.4 billion peopleare infected with A. lumbricoides,representing 25 percent of the world

population. A number of features account for its highprevalence including a ubiquitousdistribution, the durability of eggs under avariety of environmental conditions, the highnumber of eggs produced per parasite, andpoor socioeconomic conditions that facilitateits spread.


30/32

highest prevalence of ascariasis occurs in

tropical countries where warm, wet climatesprovide environmental conditions that favoryear-round transmission of infection.

Prevalence in the Philippines may reach 80-

90% in 5-9 yrs. old of groups of children inpublic elem. schools

The prevalence is also greatest in areas wheresuboptimal sanitation practices lead to

increased contamination of soil and water. The majority of people with ascariasis live in

Asia (73 percent), Africa (12 percent) andSouth America (8 percent), where somepopulations have infection rates as high as 95percent.
