Why this research matters now
Detection of H5N2 antibodies in an unvaccinated domestic duck indicates potential viral circulation in the region, highlighting the need to strengthen surveillance and control strategies for avian influenza in Guatemala.
Structured evidence summary
Research question
The study aimed to determine the seroprevalence of H5N2 low pathogenic avian influenza in domestic ducks and geese in Río Blanco, San Marcos, Guatemala.
Study design
Serological cross-sectional survey using haemagglutination inhibition testing on serum samples collected from domestic waterfowl.
Population and setting
The study sampled 112 domestic waterfowl (83 Muscovy ducks and 29 domestic geese) in the municipality of Río Blanco, San Marcos, located in Guatemala's western highlands.
Main findings
Point seroprevalence was 0.89%, with one unvaccinated Muscovy duck testing positive for H5N2 LPAI antibodies out of 112 birds sampled. The single positive detection suggests prior viral exposure and possible local circulation of H5N2 low pathogenic avian influenza in the area.
Public-health relevance
Detection of H5N2 antibodies in an unvaccinated domestic duck indicates potential viral circulation in the region, highlighting the need to strengthen surveillance and control strategies for avian influenza in Guatemala.
Important limitations
This summary is limited to the supplied single-article abstract and metadata. The full paper is required for decision-grade interpretation, including details on sampling methodology, assay performance characteristics, and generalizability beyond the sampled population.
GIDS interpretation
This article is discoverable through GIDS surveillance filters for influenza, Guatemala, and surveillance topics. It provides localized serological evidence relevant to understanding H5N2 LPAI exposure in domestic waterfowl populations in Guatemala's western highlands.
