Swimmer's itch was known to exist as early as the 19th century, but it was not until 1928 that a biologist found that the dermatitis was caused by the larval stage of a group of flatworm parasites in the family Schistosomatidae. [7]
Turkish children living shanty towns have higher prevalence than those in school provide apartments, with similar infection rates between boys and girls. [5] In rural Mexico, 25% of the children aged 6–10 in twelve schools were infected with H. nana. Socio-economic factors and lack of parent education are strong influences on the high ...
Adults of different species infest different parts of the definitive host - for example the intestine, lungs, large blood vessels, [5] and liver. [13] The adults use a relatively large, muscular pharynx to ingest cells, cell fragments, mucus, body fluids or blood. In both the adult and snail-inhabiting stages, the external syncytium absorbs ...

The Turbellaria are one of the traditional sub-divisions of the phylum Platyhelminthes (flatworms), and include all the sub-groups that are not exclusively parasitic.There are about 4,500 species, which range from 1 mm (0.039 in) to large freshwater forms more than 500 mm (20 in) long [3] or terrestrial species like Bipalium kewense which can reach 600 mm (24 in) in length.
The disease is especially common among children in underdeveloped and developing countries because they are more likely to play in contaminated water. [5] Schistosomiasis is also common among women, who may have greater exposure through daily chores that involve water, such as washing clothes and fetching water. [10]
A parasite called Heterobilharzia americana, a flatworm commonly referred to as liver fluke, was behind the illness of the 11 dogs. The parasite normally makes its home in Texas and in the South.
