|a Cyprinid herpesvirus-3 (CyHV-3) is an important pathogen of common carp (Cyprinus carpio, carp) causing significant economic and ecological impacts worldwide. The recent emergence of CyHV-3 in the Upper Midwest region of the United States has raised questions related to the disease ecology and host specificity of CyHV-3 in wild carp populations. To determine the prevalence of CyHV-3 in wild populations of fishes in Minnesota, we surveyed five lakes in 2019 in which the virus was known to have caused mass mortality events in carp from 2017 to 2018. A total of 28 species (n = 756 total fish) of native fishes and 730 carp were screened for the presence of CyHV-3 DNA using specific qPCR. None of the native fish tissues tested positive for CyHV-3 although the prevalence of CyHV-3 in carp was 10%-50% in the five lakes. A single lake (Lake Elysian) with a 50% DNA detection rate and evidence of ongoing transmission and CyHV-3-associated mortality was surveyed again in 2020 from April to September. During this period, none of the tissues from 24 species (n = 607 total fish) tested positive for CyHV-3 though CyHV-3 DNA and mRNA (indicating viral replication) was detected in carp tissues during the sampling period. CyHV-3 DNA was detected most often in brain samples without evidence of replication, potentially indicating that brain tissue is a site for CyHV-3 latency. Paired qPCR and ELISA testing for Lake Elysian in 2019-2020 identified young carp (especially males) to be the primary group impacted by CyHV-3-associated mortality and acute infections, but with no positive detections in juvenile carp. Seroprevalence of carp from Lake Elysian was 57% in 2019, 92% in April of 2020 and 97% in September 2020. These results further corroborate the host specificity of CyHV-3 to carp in mixed wild populations of fishes in Minnesota and provide additional insights into the ecological niche of CyHV-3 in shallow lake populations of carp in North America
