Detection of avian influenza virus in surface waters using passive samplers.

ABSTRACT: Avian influenza (AIV) remains a global concern not only for humans as a pandemic threat but pose a risk to poultry, wildlife, and livestock. The detection of AIV in the environment traditionally has relied on reactive surveillance, limiting proactive response. This study assessed the detection of Pan-influenza A virus (Pan-FluA) and hemagglutinin subtype H5 genes in surface water using novel passive samplers and molecular analyses. Pan-FluA RNA was detected at concentrations from 2.1 × 10⁵ to 5.6 × 10¹² copies sampler^-1 and H5 RNA at concentrations from 2.2 × 10⁴ to 1.8 × 10¹¹ copies sampler^-1. Detections aligned with fall migration and waterfowl activity but also underscored the importance of monitoring interface zones infl
