Frequency. United States. Trichuriasis: Recent estimates indicate that 2. United States are infected with Trichuris trichiura (whipworm), mainly in the rural Southeast. Enterobiasis: This is the most common of all helminthic infections, with an estimated 4. Ascariasis: An estimated 4 million people, mainly in the Southeast, are infected with Ascaris species. Hookworm: This infection still has a low degree of prevalence in the Southeast. Strongyloidiasis: A prevalence rate of 0. Trichinosis: The prevalence rate is 4- 2. Anisakiasis: Annually, fewer than 1. United States. International. Trichuriasis: Infection with T trichiura is one of the most prevalent nematode infections worldwide; approximately 8. Infection rates of up to 7. Puerto Rico. Enterobiasis: Pinworm is also highly prevalent throughout the world, particularly in countries of the temperate zone. Children are most commonly infected. Estimated prevalence rates among children in various world regions are 4–2. Ascariasis: Ascaris, or roundworm, infection is the common helminthic infection in humans, with an estimated worldwide prevalence of 1 billion. The causative organism, A lumbricoides, is cosmopolitan in distribution, being most abundant in tropical countries. Hookworm: Human infection with the 2 species of hookworm, A duodenale and N americanus, is estimated to affect approximately 5. Strongyloides stercoralis is also endemic in Jamaica and presumably elsewhere in the Caribbean. An estimated 3. 0- 1. Trichinosis: Trichinella species are distributed throughout the world and are spread widely in nature among a large number of carnivorous animals, with humans acting as an incidental host. Trichinosis has been a major public health problem and has been reported in many Asian countries, including China, Japan, Korea, and Thailand. Dracunculiasis: Estimates of the number of people infected with Dracunculus medinensis in Africa, the Middle East, India, and other tropical areas range from 5. An aggressive eradication campaign has been underway to eliminate D medinensis, which is called the Guinea worm. Filariasis: An estimated 1. Wuchereria bancrofti, Brugia malayi, and Brugia timori. Loiasis: Loa loa is irregularly distributed in Africa. It is estimated that between 3 and 1. West and Central Africa are infected. Onchocerciasis: Onchocerca volvulus infects 2.

Anisakiasis: Approximately 2. Japan and most others from Spain, the Netherlands, and Germany, depending on the habits of fish consumption. Some of the more serious nematode infections result in symptoms from inflammatory responses in vital organs and nutritional deficiencies. Race. Nematode infections have no known racial predilection. Sex. Nematode infections have no known sexual predilection. Age. E vermicularis infection (pinworm) is more common in children than in adults.
