“Who is at risk for amebiasis?
Although anyone can have this disease, it is more common in people who live in tropical areas with poor sanitary conditions. In the United States, amebiasis is most common in:
* People who have traveled to tropical places that have poor sanitary conditions
* Immigrants from tropical countries that have poor sanitary conditions
* People who live in institutions that have poor sanitary conditions
* Men who have sex with men

Bingo, these parasites do not typically occur in healthy people who live in countries with good sanitation.
Rare parasitic disease spreads among HIV-infected gay men. Amebiasis, a rare parasitic disease traditionally transmitted by contaminated water, has been transmitted by sex between HIV-positive gay men, according to a researcher at the University of Antwerp and the Institute of Tropical Medicine Antwerp. Amebiasis, an infection with the single-celled amoeba Entamoebia histolytica, exists in areas where the amoeba is endemic and where hygiene is substandard, leading to contact with contaminated water. The amoeba invades the intestinal lining and causes a bloody diarrhea, or when it enters the bloodstream it can cause liver abscesses. The researcher showed seropositive (HIV-infected) gay men in Taiwan are infected more often with the amoeba than the healthy population and also more often than seropositive heterosexuals. Using modern molecular techniques, the researcher showed that men from different regions are being infected by closely related amoebas.
