After the request of the Ministry of Agriculture and Fisheries, Food and Environment, the representatives of the world of hunting to assist in the detection of possible cases of african swine fever (asf) in wild boar, the Royal Spanish Hunting Federation (RFEC) asked for the hunters to communicate any finding that is suspected in the field, since, despite the fact that the risk is low, you should not neglect their monitoring.
Although the foci of PPP are emerging in distant countries of the Iberian peninsula, the occurrence of several cases in the Czech Republic at the end of June, together with the worsening of the situation in countries previously affected (Poland, Latvia, Lithuania and Estonia), which represents a significant increase in the risk of arrival of the disease, so that the MAPAMA it is checking the movements of risk from the affected areas of our country.
As has informed the Ministry of Agriculture to the RFEC, the PPA affects the wild boars causing the death of more than 90% of those affected in less than a week since the infection. Sometimes, however, the infection is not fatal and can give rise to animals carrying the virus, which favors the spread of the disease in the environment.
The Royal Spanish Federation of Hunting, because hunters are in direct contact with the wild fauna, considered appropriate are kept informed about this situation and are aware of the main symptoms of the disease, for, if there is the case, be able to communicate to the official veterinary services, any finding that is suspect in the field, as they could be symptoms consistent with the illness (primarily symptoms of bleeding), or mass mortalities in the same area.
On the african swine fever (asf)
The PPA is a highly contagious disease, caused by a virus of the genus Asfivirus, with pictures acute or per-acute with a mortality rate close to 100%, while on other occasions it presents with clinical sub-acute or even chronic with lower mortality.
Affects pigs, both in the domestic animals (pigs) and in wildlife (wild boar).
Spain in the year 1995, was declared ‘free from disease’, and the situation remains until the present day.
It causes hemorrhagic lesions in skin and internal organs, but, unlike classical swine fever, it does not appear, typically, symptoms of nerve. In any case, it is impossible to differentiate these two diseases only by their symptoms and in case of suspicion is made, a diagnostic laboratory that allows for their differentiation.
There is No vaccine against this disease.
It is considered that this disease has a high potential to spread extensively and rapidly at the international level. In fact, there is a constant risk of spread of the disease to be the most important risk factors for the introduction of meat pork infected and the movement of wild boars infected.
It seems that in the countries of eastern Europe affected by the current outbreak is playing the wild boar an important role in the maintenance of the disease in the area. The scientific opinion most prevalent is that the absence of scavenger species, coupled with the low temperatures of winter, make the carcasses of the boars dead are kept in the field for long periods of time (through the winter) while remaining as a source of infection for the jabatos of the following spring.
