Taeniasis-cysticercosis in Honduras

Area of Science:

• Veterinary Medicine
• Infectious Diseases
• Public Health

Background:

• Human taeniasis and cysticercosis, caused by the tapeworm Taenia solium, pose significant public health challenges globally.
• Limited data exists on the prevalence and impact of these parasitic infections in Honduras.
• Understanding transmission dynamics is crucial for effective control strategies.

Purpose of the Study:

• To investigate the prevalence of human taeniasis and human and animal cysticercosis in Honduras.
• To identify risk factors and transmission patterns of Taenia solium infections.
• To assess the diagnostic advancements in human cysticercosis detection.

Main Methods:

• Data collection from laboratory, medical, and slaughterhouse records.
• Proglottid identification and species speciation (Taenia solium).
• Community surveys to determine infection rates.
• Analysis of pig and cattle cysticercosis at abattoirs.
• Review of human cysticercosis diagnoses before and after advanced imaging/assays.

Main Results:

• Human taeniasis rates varied significantly across regions, with higher prevalence in southern provinces.
• Taenia solium was identified in 74.5% of proglottid samples, including young children.
• Pork cysticercosis rates were 5%, while cattle cysticercosis was 0.05%.
• Human cysticercosis diagnoses increased fivefold following the introduction of CT scans and ELISA, particularly in neurosurgical wards.

Conclusions:

• Taeniasis-cysticercosis represents a serious and potentially underestimated health problem in specific areas of Honduras.
• The high prevalence of Taenia solium in humans and pigs highlights the need for targeted interventions.
• Improved diagnostic tools have significantly enhanced the detection of human cysticercosis.
