High Prevalence of Highly Pathogenic Avian Influenza: A Virus in Vietnam's Live Bird Markets.

ABSTRACT:

Background

In recent years, Vietnam has suffered multiple epizootics of influenza in poultry.

Methods

From 10 January 2019 to 26 April 2021, we employed a One Health influenza surveillance approach at live bird markets (LBMs) and swine farms in Northern Vietnam. When the COVID-19 pandemic permitted, each month, field teams collected oral secretion samples from poultry and pigs, animal facility bioaerosol and fecal samples, and animal worker nasal washes at 4 LBMs and 5 swine farms across 5 sites. Initially samples were screened with molecular assays followed by culture in embryonated eggs (poultry swabs) or Madin-Darby canine kidney cells (human or swine swabs).

Results

Many of the 3493 samples collected had either molecular or culture evidence for influenza A virus,
