Evolution of Bluetongue in Spain in the period of vector activity of 2011-2012.
In the period of vector activity of 2011 - 2012 (October to March) have been reported twelve outbreaks of bluetongue (BTV) in Spain. The serotypes responsible of the outbreak have been the serotype 1 and 4, not finding any outbreak of serotype 8 in this period (the last outbreak in 2010) (Figure 7). Nine outbreaks of serotype 1 have been declared between October and January. These outbreaks have been detected in sentinel farms in the province of Caceres and on the border in the province of Salamanca, where outbreaks have been detected in the recent years. From this date has not shown the presence of further outbreaks of the disease. In addition, the serotype 4 was detected in March 2012 within the restriction zone for serotypes 1, 4 and 8 in the provinces of Huelva and Seville, highlighting its detection in wildlife.

In addition, this period was marked by the modification of the Order ARM/3373/2010 by the Order ARM/1614/2011. This Order established a model voluntary vaccination since July 31, 2011. Therefore, the important awareness of veterinarians and farmers of the benefits of vaccination as a control measure for the disease and their appropriate application has allowed to continue a favorable epidemiological evolution, decreasing the number of outbreaks in this period (table 2).

The second season of Schmallenberg disease has begun.
In the first epidemic wave Schmallenberg virus (SBV) infection affected eight countries in the European Union: Germany (December 2011), Netherlands (December 2011), Belgium (December 2011), United Kingdom (January 2012), France (January 2012), Italy(February 2012), Luxembourg (February 2012) and Spain (March 2012). Though the end of the season was declared to be at the end of May 2012, Denmark declared the first fetus affected by the SBV infection in June in the island of Funen (Figure 1, detail), while some weeks before antibodies against the virus were found in cattle in Jutland (Figure 1, detail). Moreover, the virus was detected in pools of midges of the genus Culicoides (species unknown yet) caught in October 2011, which means SBV has been circulating in very northern latitudes.

Situation of West Nile in european environment in 2012.
In the European Union West Nile (WN) cases have only been reported during 2012 in equine in Greece and Croatia (Figure 1). Greece began suffering the disease in horses in 2010. Since then, at least 59 horses have been affected by the WN virus infection. As for Croatia, this is the first time that WN outbreaks are reported, having affected six horses. This is not surprisingly, given the active movement that the virus is having in recent years in the area (Figure 1). Although official data is not available yet, it is likely that lineage 2 is the responsible for the outbreaks in both countries.

The European Society for Veterinary Virologyat its IX Congress elected Sánchez-Vizcaíno as its new ESVV president succeeding current president Professor Sándor Belák.
Interview with Professor José Manuel Sánchez-Vizcaíno to Colombian Pig.
Prof. Sánchez-Vizcaíno will talk about ASF: Emerging threat (symptoms, diagnosis, control and prevention) in Ho Chi Minh City (Vietnam) during the OIE/FAO Regional Workshop on Swine Health Management in South‐East and East from 22-24 August and the oral communication: Overview of the current research on African Swine Fever in the Vaccine and Diagnostcs for transboundary Animal Disease in the congress in Ames, Iowa (USA) from 17th to 19th of September.
African swine fever continues causing problems in the Tver region, located on the north of the Russian capital, Moscow. The first outbreaks in this region appeared in May 2011, with the involvement of 127 domestic pigs. Successive outbreaks occurred affecting both domestic and wild population of the area (in June, July and November 2011). This fact was identified as a signal of danger evolution of the disease, implying the existence of viral circulation in the area, and therefore an increased risk of dissemination and maintenance of ASF in the area.
These predictions have been recently confirmed with the detection of an infected boar in Lihoslavlsky area during the month of June of this year, revealing that the virus has remaines in the area during these months. This area, located in the Tver region, has not reported outbreaks before, so the alarms have started on the Russian Veterinary Services, to the insufficient knowledge of the extent of the problem. These Services has begun a program to prevent spread and eradication of ASF in the area, including the census of all animals in the region.
On the other hand, unofficial sources have reported the presence of several outbreaks in the Tula region, at the south of the capital. In fact, this area it has been considered by the Federal Veterinary Service (Rosselkhoznadzor) as the current hot spot of the disease in the country. Waiting for official notification to the OIE confirming these outbreaks this fact, the truth is that the spread and persistence of the disease in this region, where the pig population is much higher than many regions in the country, could mean significant economic losses, and further complications for the control of the disease.
The dissemination and persistence of ASF in these two regions is a step in the progressive approach of the disease to the northwest and therefore to the borders of neighboring countries such as Ukraine and Belarus and neighboring countries of the EU.
