New Bluetongue Virus Variant Identified

A concerning development has emerged from the Netherlands as a new variant of the bluetongue virus, known as BTV-12, has been identified in sheep in Kockengen. This alarming discovery was confirmed by experts at Wageningen Bioveterinary Research, which is affiliated with Wageningen University & Research. The identification of this novel serotype was validated by the European Bluetongue Reference Laboratory located in Madrid.

Follow-Up Research and Testing

Following the initial detection, extensive follow-up research was conducted within a five-kilometer radius around the infected sheep. Alarmingly, another ruminant, a cow, from the same vicinity tested positive for BTV-12 based on analyses from Wageningen Bioveterinary Research. This particular sample has been sent for further verification to the European Reference Laboratory, with results anticipated early next week. Interestingly, the cow in question had calved in September, and both it and its calf have been screened by the Dutch Food and Consumer Product Safety Authority (NVWA) for the virus.

Authorities Respond

Authorities are taking this matter very seriously. The Dutch ministry of Agriculture, Fishery, Food Security, and Nature (LVVN), under the direction of Minister Femke Wiersma, has mandated that all bluetongue-positive samples sent for testing since September 1 be re-evaluated to check for the presence of BTV-12. This proactive measure aims to ensure the safety and health of livestock in the country, with results from this comprehensive review expected within the next week.

Public Health Concerns

It's crucial to note that BTV-12 and the previously known variant BTV-3 are genetically unrelated. Melle Holwerda, a virologist and head of the National Reference Laboratory, has expressed uncertainty regarding the virus's origins and the extent of its spread. 'We do not yet know where else BTV-12 may be found beyond the two confirmed cases we have identified to date,' Holwerda stated. He emphasized the importance of reporting any suspected bluetongue cases to the NVWA promptly.

Farmers Urged to Stay Informed

As concerns grow over animal health and potential economic impact, the farming community is urged to stay vigilant and informed. Continued monitoring and cooperation with health authorities will be vital in managing the spread of this new bluetongue virus variant. Stay tuned for updates as new information becomes available!
