Schmallenberg virus - Dutch testing humans


Up-to-date figures from the Netherlands Government and a very proper proposal from the cautious Dutch on testing humans.

In Britain, the government veterinarians are still trying to locate the English Channel and hanging onto the theory that the wind from France, which did not have any cases in the area facing England, blew midges carrying Schmallenberg Virus ( SBV) to Norfolk, which as any school atlas will tell you, is many miles away from the English Channel and actually on the North Sea. 

Oxford University using continental data have today, dealing with earlier epidemics of bluetongue, a different disease, asserted that the midges can fly against the wind anyway. Even so it is a long way across the North Sea.

Anyway, here is the Dutch government, on the ball, as always.



Schmallenberg virus now confirmed at 3 cattle farms, 88 sheep farms and 5 goat farms

Minister for Agriculture and Foreign Trade Henk Bleker has notified the House of Representatives that the Netherlands Food and Consumer Product Safety Authority (NVWA) has at 8 February 2012 received reports from 450 farms of symptoms that could indicate infection with the Schmallenberg virus. These reports have been received from 168 sheep farms, 261 cattle farms and 21 goat farms. The virus has been confirmed at 3 cattle farms, 88 sheep farms and 5 goat farms. Testing continues on a further 91 farms.

In Germany the virus has since been detected at 10 cattle farms, 317 sheep farms and 15 goat farms. In Belgium the virus has been found at 4 cattle farms, 83 sheep farms and 1 goat farm. As at 30 January the virus has been detected at 50 sheep farms in France and as at 25 January there have been confirmed cases at 32 sheep farms, 1 cattle farm and 1 goat farm in the United Kingdom.
Public Health
The Netherlands Environmental Assessment Agency (RIVM) has concluded that based on all available information, transmission of the virus to humans is highly unlikely. To identify human cases of the virus both a viral antibody test and a test to identify the virus itself have been developed. The RIVM is working on a proposal to test larger groups of people in order to assess whether exposure to the virus can lead to infection. A number of experts will meet next week to discuss this proposal, as well as the theoretical risk to humans and what research is required to reach a definitive conclusion on this matter.
