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.

Denmark declares the first outbreak of the Schmallenberg disease.

The first season of occurrence of the Schmallenberg disease (SBD) is coming to an end. In fact, on June 1, the eight affected countries declared the resolution of the nearly 3,500 outbreaks suffered from December 2011 to May 2012 in sheep, cattle and goats (Figure 1). 

Fig. 1: Number of outbreaks of Schmallenberg disease in the eight European countries affected until June 11th, 2012 (Source: self elaboration based on data in WAHID-OIE). In detail, the purple star denotes the first Schmallenberg disease outbreak in cattle in Fyn (Denmark); the blue cross indicates the first seropositive animals in Jutland.

 

However, on June 6, Denmark declared the first case of SBD on the island of Funen (Figure 1, detail). This case appeared in a cattle holding in Fyn, where a fetus born with compatible malformations appeared, and the virus could be detected by PCR. No symptoms in adult animals were detected in the holding during autumn 2011, but the mother presented  antibodies against the virus.

Although this is the first confirmed case in Denmark, a total of 56 animals have come to study as compatible cases, but only this one has tested positive to the PCR. In addition, a few weeks before antibodies were detected in two cattle from a farm in Jutland (Figure 1, detail). Furthermore, the virus was detected in pools of Culicoides midges (unspecified species) collected in October 2011.

All these evidences suggest that, like the serotype 8 bluetongue virus, the Schmallenberg virus has been circulating over Europe up to quite northern latitudes. Further studies are needed to understand how this pathogen is transmitted.
