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.

印度泰米尔纳德邦未知血吸虫的人类传播以及南亚本土血吸虫病的回顾

印度泰米尔纳德邦的一项粪便调查显示，有两人通过了血吸虫卵，后来被鉴定为未知血吸虫，一种猪、狗和老鼠的寄生虫。我们调查了这些病例并审查了印度和尼泊尔的本土血吸虫病病例。这2例新病例是真实感染还是虚假传代尚不确定。
