Virus titers in oral and cloacal samples of ducks exposed to simulated live poultry market slaughter of highly pathogenic avian influenza A/Vietnam/1203/04(H5N1) virus–infected ducks in study of airborne transmission of highly pathogenic influenza virus during processing of infected poultry. Shedding titers are expressed as log10 with error bars included. Numbers on top of the bars indicate the number of positive samples out of the 5 tested samples at each time point. The limit of detection was 0.9 log10 median egg infection dose/mL.
