“…The expected prevalence was determined according to previously reported serological data from cattle and native goats in the ROK ( 9 , 23 , 27 ). Herds and animals within such herds were chosen by a simple random sampling method in each province based on the government's national statistics according to the methods previously reported ( 29 ). Serum samples from cervids were obtained from two separate sources: (1) the serum bank of the National Foot-and-Mouth Disease (FMD) Surveillance Program maintained by the Foreign Animal Diseases Division of the National Veterinary Research and Quarantine Service (Anyang, the ROK) in 2011; and (2) free-ranging cervids rescued by local rescue parties or housed at wildlife rescue centers during the 2011 FMD epidemic in the ROK ( 30 ).…”

“…An additional 43 cervid blood samples from animals [Korean water deer ( Hydropotes inermis argyropus ) and Siberian roe deer ( Capreolus pygargus )] rescued by local rescue parties or housed at captured wildlife rescue centers were available for testing. Cervid blood collection and serum preparation were performed according to previously reported methods ( 29 ).…”

“…Signs typical of Aino virus infection were not observed in any of the studied animals. Risk factor information was obtained from (1) the Korea Animal Health Integrated System (Animal and Plant Quarantine Agency, Anyang, ROK); (2) veterinarians in wildlife rescue centers; and (3) animal owners using a questionnaire form according to the methods previously reported ( 29 ). We investigated associations between the seroprevalence and seropositivity risk factors such as herd population size, age class, species, and location.…”

Aino virus is an infectious, non-contagious, vector-borne agent that has been implicated in arthrogryposis-hydranencephaly syndrome in newborn cattle, sheep, and goats. Information about reservoirs and host animal species susceptible to Aino virus remains unclear. To further explore the role of cervids in Aino virus infection transmission, we investigated cervid sera to determine the prevalence of Aino virus-neutralizing antibodies and to identify factors correlated with antibody positivity. We screened cervid serum samples collected in the Republic of Korea to better understand infection patterns in this animal species. Overall, Aino virus infection was widespread; 75 of 716 (10.5%, 95% [95% CI] = 8.4–13.4) farmed-cervid serum samples collected from 292 herds contained antibodies to Aino virus. Serological evidence of Aino virus infection was demonstrated in 5 of 43 free-ranging cervids, accounting for a prevalence rate of ~11.6% (95% CI = 4.6–26.4). Our results revealed that age class and geographic location affected seroprevalence. The main risk factors associated with Aino virus seroprevalence were older age (> 2 years old, OR = 2.221, 95% CI = 1.209–4.079, P = 0.009 in adults), southern provinces (OR = 2.432, 95% CI = 1.445–4.093, P = 0.001), and western provinces (OR = 1.905, 95% CI = 1.041–3.488, P = 0.034). The results in this study suggest that cervid species might serve as important hosts for the transmission of Aino virus, highlighting the need for careful monitoring of Aino virus infections in cervids.

“…However, no clinical cases of bluetongue have been observed. In Korea, BTV-1 was isolated from a bovine blood sample collected at an abattoir in 2012 (142), and thereafter, the circulation of BTV was confirmed in goats, deer, and dairy cattle by serological surveillance (143)(144)(145). Seven BTV serotypes have been detected in Korea to date.…”

Endemic and Emerging Arboviruses in Domestic Ruminants in East Asia

Epizootic congenital abnormalities caused by Akabane, Aino, and Chuzan viruses have damaged the reproduction of domestic ruminants in East Asia for many years. In the past, large outbreaks of febrile illness related to bovine ephemeral fever and Ibaraki viruses severely affected the cattle industry in that region. In recent years, vaccines against these viruses have reduced the occurrence of diseases, although the viruses are still circulating and have occasionally caused sporadic and small-scaled epidemics. Over a long-term monitoring period, many arboviruses other than the above-mentioned viruses have been isolated from cattle and Culicoides biting midges in Japan. Several novel arboviruses that may infect ruminants (e.g., mosquito-and tick-borne arboviruses) were recently reported in mainland China based on extensive surveillance. It is noteworthy that some are suspected of being associated with cattle diseases. Malformed calves exposed to an intrauterine infection with orthobunyaviruses (e.g., Peaton and Shamonda viruses) have been observed. Epizootic hemorrhagic disease virus serotype 6 caused a sudden outbreak of hemorrhagic disease in cattle in Japan. Unfortunately, the pathogenicity of many other viruses in ruminants has been uncertain, although these viruses potentially affect livestock production. As global transportation grows, the risk of an accidental incursion of arboviruses is likely to increase in previously non-endemic areas. Global warming will also certainly affect the distribution and active period of vectors, and thus the range of virus spreads will expand to higher-latitude regions. To prevent anticipated damages to the livestock industry, the monitoring system for arboviral circulation and incursion should be strengthened; moreover, the sharing of information and preventive strategies will be essential in East Asia.
