Summary
Draws attention to the serious - and growing - public health problem posed by foodborne trematode infections. These infections, which affect an estimated 40 million persons, are linked to several serious diseases, including cholangiocarcinoma in Opisthorchis infections, cholangiocarcinoma and gall stone in Clonorchis infection, and severe clinical liver disease in Fasciola infection. Infection is acquired via the consumption of raw or inadequately processed freshwater fish, shellfish, and aquatic plants. Awareness of the magnitude of suffering and disease caused by foodborne trematode infections has increased dramatically following recent changes in Eastern Europe, where millions of people are now known to be infected with Opisthorchis and where cholangiocarcinoma is the leading cause of hepatic cancer. The misdiagnosis of tuberculosis in persons suffering from paragonimiasis poses yet another public health problem of growing concern.
The book, which has three parts, aims to assemble all the practical and technical information needed to develop effective strategies for control. The first part presents basic information about foodborne trematode infections, their modes of transmission, and the methods available for control. Also included is the first detailed analysis of the geographical distribution of foodborne trematode infections. The second part provides a state-of-the-art review of what is known about the clinical features of these diseases, patterns of morbidity and mortality, the parasites, and their intermediate snail hosts. The final part summarizes country experiences in the epidemiology and control of foodborne trematode infections.
