*Shedding was determined by real-time reverse transcription–PCR of nasal swabs compared with standard curves generated from avian influenza virus stocks of known concentrations and expressed as 50% log10 egg infectious dose equivalents. –, no viral RNA detected.
†Uninoculated raccoons housed in cages adjacent to infected raccoons.
