“…12,13 The lower seroprevalence in calves could also be due to some of the calves investigated might be PI animals which are known to be immunotolerant to the virus and do not produce antibody against the virus to be detected by the ELISA Ab test. According to Fulton et al 4 the prevalence of PI animals in South Central United States was revealed to be 0.55%, while Houe et al 22 recorded the prevalence of PI animals in Michigan (USA) to be 0.13%.…”

“…9,10 In Australia, the prevalence of BVDV exposed cattle herds was reported to be high varying from 82-100%. 11,12 Although reports varied across states, a seroprevalence of 75-85% of BVDV antibody in adult cows was documented in Australia. 13 Thailand and Argentina have also reported a BVDV prevalence of 73% and 70% respectively, 1,14 while a prevalence of 24.7% is reported recently from smallholder dairy units in India.…”

Research ABSTRACTThe aim of this study was to investigate Seroprevalence of Bovine Viral Diarrhea Virus (BVDV) infection in cattle in the state of Selangor, Malaysia and associated risk factors. A total of 407 blood samples were collected from five selected farms within Selangor. Sampled animals were identified for their breed, age, lactation and pregnancy status. The plasma extracted from blood samples were used for detection of antibody against BVDV using an ELISA test kit (Prio-CHECK ® BVDV antibody) following the manufacturer's protocol. Results demonstrated an overall 33.2% (135/407) prevalence of BVDV antibody; with four of the farms tested positive. Prevalence in one farm reached 75.9% (66/87) which was higher than the other four farms with a prevalence of 26.0% (66/254), 13.3% (2/15), 2.8% (1/36) and 0% (0/15). Animals grouped according to breed, age, lactation and pregnancy status showed significant variation in BVDV prevalence. Higher number of adults (36.7%) than young calves (15.2%), pregnant (42.9%) than non-pregnant (31.1%) and more lactating (51.1%) than non-lactating (25.8%) cows, were affected (p<0.05). Friesian-Sahiwal and Jersey cattle were the most affected while the local Kedah-Kelantan cattle were the least affected. In conclusion, the study revealed immense exposure of cattle in Selangor to BVDV infection that varied with breed, age, lactation, and pregnancy status of the animals. As to our knowledge, this is the first report on BVDV status in cattle in Malaysia and the seroprevalence result would serve as a baseline data for further investigation on the disease.

“…The prevalence of BVDV in Australian cattle herds has been recently reported to be as high as 80% . Losses to the Australian cattle industry caused by BVDV infection are estimated to be at least A$114.4 million, prompting discussion on the feasibility of systematic BVDV control programs in Australia . The ability of non‐bovine species to maintain BVDV infection and act as a reservoir host has been identified as a possible threat to control efforts .…”

Bovine viral diarrhoea (BVD) has been assessed according to the criteria of the Animal Health Law (AHL), in particular criteria of Article 7 on disease profile and impacts, Article 5 on the eligibility of BVD to be listed, Article 9 for the categorisation of BVD according to disease prevention and control rules as in Annex IV and Article 8 on the list of animal species related to BVD. The assessment has been performed following a methodology composed of information collection and compilation, expert judgement on each criterion at individual and, if no consensus was reached before, also at collective level. The output is composed of the categorical answer, and for the questions where no consensus was reached, the different supporting views are reported. Details on the methodology used for this assessment are explained in a separate opinion. According to the assessment performed, BVD can be considered eligible to be listed for Union intervention as laid down in Article 5(3) of the AHL. The disease would comply with the criteria as in Sections 4 and 5 of Annex IV of the AHL, for the application of the disease prevention and control rules referred to in points (d) and (e) of Article 9(1). The assessment here performed on compliance with the criteria as in Section 3 of Annex IV referred to in point (c) of Article 9(1) is inconclusive. The animal species to be listed for BVD according to Article 8 (3) criteria are mainly species of the families Bovidae, Cervidae and Camelidae as susceptible species and several mammalian species as reservoirs.
