In October 2017, ILRI researchers and partners from Vietnam and US conducted a pilot study of aerosol sampling surveillance in a large wholesale live bird market in Hanoi. Of the air samples collected during a three-week period, 90% were positive for molecular evidence of influenza A. These results were positively associated with molecular results from oropharyngeal swab samples collected from chickens and ducks. Noninvasive bioaerosol samplers may serve as an early warning screening tool for novel influenza virus detection in live bird markets. Continue reading →
