Overview

Demonstrates improved species identification in Chagas disease surveillance, suggesting better taxonomic accuracy in health labs.

Key Points

  • The aim is to evaluate the effectiveness of External Quality Assessment (EQA) in identifying triatomine species related to Chagas disease.
  • Conducted EQA in four municipalities in Pernambuco
  • Sent 12 adult Hemiptera specimens for identification to health laboratories
  • Evaluated accuracy of species identification by participating labs
  • Achieved 68% accuracy in species identification
  • Identified challenges with morphologically similar species like the genus Rhodnius
  • Highlighted the necessity of ongoing training for laboratory personnel
