Summary
Fish-borne parasitic zoonoses are expanding globally, affecting more populations due to international trade and travel. This review details key diseases like liver fluke infections and anisakiasis, emphasizing research needs for control.
Area of Science:
- Parasitology
- Public Health
- Foodborne Diseases
Background:
- Fish-borne parasitic zoonoses traditionally affect low- and middle-income countries.
- Global trade, travel, and migration are expanding their reach and at-risk populations.
- These helminthic diseases (trematodes, cestodes, nematodes) cause significant human infections worldwide.
Purpose of the Study:
- To review the epidemiology, clinical aspects, and control of major fish-borne parasitic zoonoses.
- To highlight the expanding geographical distribution and at-risk populations.
- To identify research gaps for improved risk assessment and management.
Main Methods:
- Literature review focusing on specific fish-borne parasitic zoonoses.
- Emphasis on liver fluke diseases (clonorchiasis, opisthorchiasis, metorchiasis).
- Inclusion of intestinal trematodiasis, anisakiasis, and diphyllobothriasis.
Main Results:
- Fish-borne parasitic zoonoses are increasingly recognized beyond their traditional endemic areas.
- Key diseases reviewed include liver flukes, heterophyids, echinostomes, Anisakis simplex, and Diphyllobothrium.
- Understanding life cycles, distribution, and clinical features is crucial for control.
Conclusions:
- Fish-borne parasitic zoonoses pose a growing global health challenge.
- Effective prevention and control require integrated strategies addressing life cycles and human behavior.
- Further research is essential for accurate risk assessment and improved clinical management.
