Human Passage of Schistosoma incognitum, Tamil Nadu, India, and Review of Autochthonous Schistosomiasis, South Asia.

ABSTRACT

A fecal survey in Tamil Nadu, India, revealed 2 persons passed schistosome eggs, later identified as Schistosoma incognitum, a parasite of pigs, dogs, and rats. We investigated those cases and reviewed autochthonous schistosomiasis cases from India and Nepal. Whether the 2 new cases represent true infection or spurious passage is undetermined.
