Summary

Human taeniasis and cysticercosis are significant health issues in Honduras, with infection rates varying by region. Taenia solium is a common cause, affecting both humans and livestock, particularly pigs.

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.
