Fasciolosis, also known as liver fluke disease, is a parasitic infection caused by the trematode worms Fasciola hepatica and Fasciola gigantica. These parasites primarily affect livestock, including sheep, cattle, and goats, but can also infect humans. Fasciolosis is prevalent in various regions worldwide, particularly in areas with suitable environmental conditions for the intermediate host, freshwater snails.
The prevalence of fasciolosis varies depending on geographical location and local factors. In some regions, such as parts of South America, Africa, and Asia, the disease is considered endemic, with high infection rates in both animals and humans. In these areas, poor sanitation, limited access to clean water, and agricultural practices contribute to the spread of the disease.
In livestock populations, the prevalence of fasciolosis can be significant, leading to economic losses due to reduced productivity and treatment costs. In humans, the prevalence is generally lower, but still poses a public health concern, especially in communities where consumption of raw or undercooked aquatic plants is common.
Efforts to control fasciolosis involve various strategies, including deworming of livestock, improving sanitation, and raising awareness about the risks associated with consuming contaminated water or plants. Regular monitoring and surveillance are crucial to assess the prevalence and implement appropriate control measures.
