CONCLUSIONSCONCLUSIONSNo outbreaks of BTV-8 in Campo de Gibraltar LVU since November 2010
European Countries that has been affected by BTV-8, with some exceptions, are free
Countries more geographically close to Spain: Portugal, France and Morocco are free of BTV-8.
The monitoring and surveillance program implemented in Spain observes the requirements set out in Annex I of Regulation 1266/2007 as regards the monitoring in order to provide the Commission with substantiatedinformation demonstrating the absence of bluetongue virus circulation in an epidemiological relevant geographical area during a period of two years
Program’s results in the last 2 years (including 3 full vector activity period): there have no been BTV-8 circulation in Campo de Gibraltar LVU
Spain is in position to declare BTV-8 freedom in Campo de Gibraltar LVU
