Hydatidosis- chinococcosis in Libya (review article)

Area of Science:

• Veterinary Public Health
• Parasitology
• Epidemiology

Background:

• Cystic echinococcosis (CE), caused by Echinococcus granulosus, poses a significant threat to public health and livestock economies in Libya.
• Historical data from 1970 onwards indicates varying classifications of CE prevalence, from hyper-endemic to endemic.
• Accurate epidemiological classification is crucial for effective disease control strategies.

Purpose of the Study:

• To review and synthesize available data on cystic echinococcosis in Libya since 1970.
• To critically assess the epidemiological status of CE in Libya based on established criteria.
• To provide a realistic assessment of CE prevalence for public health and economic impact.

Main Methods:

• Comprehensive literature review of studies on hydatidosis in Libya from 1970 to the present.
• Analysis of reported incidence rates in the human population.
• Evaluation of infection rates in the ovine population (sheep).

Main Results:

• Human incidence rates reported as >1 per 100,000 do not meet WHO criteria for hyper-endemicity.
• Ovine hydatidosis rates around 12.7% are below the 50% threshold for hyper-endemic classification.
• Previous classifications of hyper-endemicity may not be accurate based on current data.

Conclusions:

• Cystic echinococcosis in Libya is more accurately described as endemic rather than hyper-endemic.
• Current data suggests that Libya does not meet the World Health Organization's criteria for hyper-endemicity.
• Further targeted surveillance and control measures are necessary to manage endemic CE.
