Abstract

In response to unusual crow die-offs from avian influenza A(H5N1) virus infection during January-February 2017 in Dhaka, Bangladesh, a One Health team assessed potential infection risks in live bird markets (LBMs). Evidence of aerosolized avian influenza A viruses was detected in LBMs and in the respiratory tracts of market workers, indicating exposure and potential for infection. This study highlighted the importance of surveillance platforms with a coordinated One Health strategy to investigate and mitigate zoonotic risk.

Keywords: Bangladesh; avian influenza; avian influenza A virus; influenza in birds; live bird market; pathogen transmission.
