A. Location of Uruguay in South America. B. Map of Uruguay showing localities and departments of Montevideo, Salto, Paysandú and Canelones where the fasciolid flukes and the lymnaeid snails were collected. Other departments highlighted are those where most of the human fascioliasis cases have been reported.
