Denmark Outbreak of Schmallenberg disease

11/6/2012

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).

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.

Current status of the Schmallenberg disease

11/5/2012

Emeging diseases online    The infection with the Schmallenberg virus (SBV)continues its spread in Europe. From the description of the first cases of congenital malformations (mainly by the arthrogryposis-hydranencephaly syndrome) in December 2011, more than 3,200 farms have declared outbreaks of SBV infection in eight EU countries: Germany, The Netherlands, Belgium, UK, France, Luxembourg, Italy and Spain. However, according to official sources in each country, we know that there are almost 4,000 affected farms in just 6 months (Figure 1).

Fig. 1 (click to enlarge): Number of outbreaks of Schmallenberg in the eight EU countries affected to 11 May 2012. Data are shown notifications agencies of each country against the official statements of the OIE.


Of the total number of affected animals, sheep are the most affected (80.1%), followed by cattle (17.2%). Infection in goats seems to have been milder than in the other two species. As for the case of cattle, it is likely that outbreaks continue to appear until June 2012, transmission of the virus by the vectors occurred even until January of this year.

This situation is feasible given the uncommon weather conditions during the fall and winter of 2011, making possible the survival of the vectors until very late months. In turn, we must bear in mind that the drop of outbreaks in cattle may coincide with the start of the second wave of outbreaks, since there will be a sufficient number of vectors to start the transmission. Up to now  we do not know the consequences of this second epidemic wave, but everything indicates that this disease is much milder than other vector-borne diseases, such as bluetongue.

Schmallenberg in human

Enfermedades emergentes onlineExtremely low risk for human infection with the Schmallenberg virus.

So far there have been no reported cases of infection with Schmallenberg virus (SBV) in humans. Since the start of the outbreaks, many researchers had already suggested that the zoonotic potential of this new virus was low. The reasons to support this idea are based on the similarity of the SBV with Simbu serogroup viruses. Up to date, there has been no human infection by any of the three most homologous viruses (Akabane, Aino and Shamonda). However, it is known that at least two members of this serogroup, Oropouche and Iquitos viruses, do affect humans. In addition, the SBV is proving to have epidemiological, clinical and genetic peculiarities, not previously described. Therefore, the German Robert Koch Institute (RKI) has conducted a survey in 60 sheep and cattle owners in the estate of North Rhine-Westphalia, in order to understand the involvement of humans in the epidemiological cycle. Antibodies have not been found in any of these samples. In addition, samples of some farmers who had nonspecific symptoms (such as fever or headaches) were analyzed by RT-PCR (in case it was a recent infection) yielding negative results.

Although further investigations are needed, these results are quite encouraging. Given that these farmers have been highly exposed to the virus for several weeks (since they come from an area with a very high rate of infected animals) these findings suggest that the risk of human infection with the SBV is extremely low.

African swine fever - Recognizing the disease in field

Not long ago we warned of the current risk posed by African swine fever (ASF) for the European Union (EU) and that the main measure we must take to prevent entry is to be forewarned and informed. To this end we have prepared the following summary which we hope will clarify some practical concepts about ASF, how to recognize it and what actions to take when in the field.
