Members of the Cervidae family can harbor a number of pathogens that could potentially transmit to domestic animals and humans. Disease surveillance in cervid population is therefore important to protect the health and wellbeing of animals and humans. In the present study, we analyzed the serosurveillance testing data of free-ranging white-tailed deer (WTD) samples submitted to the Athens Veterinary Diagnostic Laboratory (AVDL) from 2017 to 2021. Sera were tested for the presence of antibodies to epizootic hemorrhagic disease virus (EHDV), bluetongue virus (BTV), bovine viral diarrhea virus (BVDV), Infectious bovine rhinotracheitis virus (IBRV) parainfluenza type 3 (PI-3) and Brucella abortus/Brucella suis. Seroprevalence of EHD and BT remained high over the last five years with an exception in 2020 where it showed a drastic decrease in prevalence. In 2017, 65.59% of samples tested were positive for EHDV antibodies and 62.04% samples were positive for BTV antibodies. In 2018, the numbers went slightly down to 55.70% for EHDV and 53.16% for BTV. The numbers remained relatively steady in 2019 with 59.38% samples showing positive results for EHDV and 57.81% samples positive for BTV antibodies. 2020 saw a drop in numbers with 20.27% positive for EHDV antibodies and 8.11% positive for BTV antibodies. In 2021, the positive numbers went back up again with 68.07% samples showing positive results for EHDV and 68.67% samples for BTV antibodies. The PI-3 antibody test results showed a range of 22.78- 60.81% of tested samples giving a positive antibody response over the five-year period. The seroprevalence of BVD was low with a positivity range of 0-4.6.9%, and that of IBR was 1.27-7.81%. Overall, the data showed a relatively high seroprevalence of EHDV, BTV and PI-3 in the free-ranging WTD population whereas the data showed a very low seroprevalence of BVDV and IBRV in WTD over the last five-year period. None of the samples tested during the study period showed any evidence of Brucellosis in WTD. The clinical significance of this data in disease transmission and epidemiology in domestic animals need to be further investigated. Continuous monitoring of diseases in cervid populations in proximity to livestock and human habitats is critical in understanding the epidemiology and taking control measures to protect livestock and public health from transmissible infectious diseases.
