Everyone associated with the industry are afraid it the pace at which the disease has spread in recent months. Aggravating the situation is the fact that is still not resolved two main factors contributing to the development of epidemics: high population density of wild boars and a large number of farms not fulfilling the rules of Biosafety.

Experts notethat the distances between the overwhelming majority of recent outbreaks is much smaller than observed during the previous wave of ASF. The reason for the growth in the number of foci, first of all, is the fact that the virus hit the region, where "network" of the pig is relatively thick, and therefore the risk of infection is much higher.

A significant problem is that the ways of penetration of the virus in households is very difficult to establish. During the ongoing investigation of epizootic veterinary Inspectorate often receives inconsistent and inaccurate, sometimes mutually exclusive. For example, in several of the affected farms the number of pigs in the database and the register did not match with the actual. In such situations, it is possible to hypothesize about the illegal trade in pigs as a factor in the spread of the disease.

ASF occurred in the farms where they were kept like pigs and cows. This creates possibilities for the penetration of the virus into the stable with grass, straw or cows in the meadows, where there are wild boars and where can I be infected Achs tissue of dead animals. The shooting of wild boars is not implemented in the least adequate to the current epizootic threat.

In recent years, the number of dead wild boars infected with the virus is growing strongly. Just this week there were 16. It also increases the percentage of infected animals among produced as a result of sanitary shootings. This indicates that more boars living and can spread disease at least 10 days after infection. For this reason, the ASF pressure on the environment in the quarantine zones more and more.
