Abstract and Introduction


Surveillance for soil-transmitted helminths, strongyloidiasis, cryptosporidiosis, and giardiasis was conducted in Mississippi, USA. PCR performed on 224 fecal samples for all soil-transmitted helminths and on 370 samples for only Necator americanus and Strongyloides stercoralis identified 1 S. stercoralis infection. Seroprevalences were 8.8% for Toxocara, 27.4% for Cryptosporidium, 5.7% for Giardia, and 0.2% for Strongyloides parasites.


Human populations in the state of Mississippi and the rest of the southeastern United States have historically been at risk for hookworm and other parasitic diseases.[1,2] With improved sanitation and economic development, soil-transmitted helminths (STH), including the hookworms Ascaris lumbricoides and Trichuris trichiura, were presumed to have been eliminated. However, a recent report of continued hookworm and strongyloidiasis transmission in a community without access to proper sanitation in Alabama, USA, has challenged this assumption.[3]
