In May 2011, these individuals had participated in an excursion during which freshwater crabs were caught and served after being toasted. Before the group infections with Paraginimus species was confirmed, 5 of the 11 patients had been misdiagnosed as tuberculosis (TB) and treated with an anti-TB drug regimen for six months. The most common and typical manifestations were eosinophilia (11/11, 100%) and pulmonary manifestations including, among others, stethalgia and cough (7/11 63.6%).

Paragonimus metacercariae were collected from 6 of 11 (54.5%) crabs caught at the infection site and were identified as Paraginiumus skrjabini by morphological and molecular examinations. Epidemiological and laboratory evidence confirmed that this is a case of group infection with P. skrjabini. As one of...
