*DPM, dressed poultry market; LPM, live poultry market; rRT-PCR, real-time reverse transcription PCR; –, no samples collected.
†Because not all positive samples from rRT-PCR were available for virus culture, isolation rates were derived by using the product of the percentage of rRT-PCR–positive samples and the percentage of those samples that were also culture-positive.
‡These positive samples from rRT-PCR did not have sufficient material available for virus culture.
