EHV-1 qPCR-positive swabs from 2 different horses (1 nasal and 1 muzzle/nares swab), all remaining swabs collected from healthy herdmates tested qPCR negative for EHV-1. For horses with clinical infection, EHV-1 was detected in 31 nasal swabs, 30muzzle/nares swabs, 7 front limb swabs, 7 feeders, 6 water troughs, and 6 rectal swabs.Not all positivemuzzle/nares swabs corre- lated with a positive nasal swab from the same set, but all other positive swabs did correlatewith a positive nasal swab in their respective set. The agreement between nasal swabs and muzzle/nares swabs was 74%. Agreement between nasal swabs and the other 4 swab typeswas low.
