Studies on clinical manifestations, diagnosis and control of paragonimiasis in China.

Paragonimiasis is a common parasitic zoonosis in China. Its clinical manifestations may be classified into two clinical entities, eg, paragonimiasis westermani type and paragonimiasis szechuanensis type. The latter mainly manifests as trematode larva migrans. The immunodiagnostic methods frequently used in the diagnosis of paragonimiasis are intradermal test, CFT and ELISA. The detection of circulating antigens in patients has been used in China for diagnosis and bithionol and praziquantel are drugs of choice in the treatment of paragonimiasis. Combined measures including mass survey, mass treatment and health education have been found to be effective in the control of paragonimiasis in China.
