Although herpesviruses such as cyprinid herpesvirus 3 (CyHV-3) can establish lifelong latent infections, little is known about latency conditions in farmed koi populations in China. We used nested polymerase chain reaction targeting the TK gene and an indirect antibody ELISA to screen asymptomatic fish obtained from southern China for evidence of CyHV-3 infection. CyHV-3 DNA could be detected either in peripheral blood leukocytes or from gills of asymptomatic koi. Most koi sera did not contain anti–CyHV-3 antibodies; however, 5 samples were ELISA positive, providing evidence of prior CyHV-3 infections. These findings suggest that koi may survive CyHV-3 infections and become virus carriers.
