The bluetongue virus is spreading among sheep. Last Monday, Gelderland still had 27 infections, but a new count already shows about 170 infections. The outlier in Gelderland is Aalten, where, according to the latest map, 8 animals have tested positive.
Nationally, the counter now stands at 503 cases, mainly in Overijssel and Gelderland, the east of North Brabant and the north of Limburg, reports the Dutch Food and Consumer Product Safety Authority. That was 94 a week ago.
The increase can be seen on the map published by the NVWA on the number of infections per place of residence. Due to the rapid increase in the virus, the map has been updated twice a week since last week, instead of once a week.
Vaccines
Since the end of April, three vaccines have become available to protect sheep from the virus, but despite the vaccinations, sheep have fallen ill and died. The virus is transmitted by infected midges (small mosquitoes) and mainly affects sheep. Symptoms include high fever, swelling, and a distinctive blue tongue.
Last week we spoke to several sheep farmers who are 'holding their breath' at the development of the virus, and then there were only 94 infections.
Whether the vaccines actually help fight the virus remains to be seen.

DJ, Most BTV cases are not that far from the German border. So far only sheep seem to be getting ill from BTV. Maybe vaccines are more effective in cattle ? 

Asymptomatic spread can be a risk. Vaccines were supposed to limit disease-not stop getting infected. (Non-sterilizing vaccines). 

BTV can spread further into other (wild) animals...
