In 2018, Achs is actively spread through Western Europe and was first penetrated China, affecting 28 provinces. At the beginning of 2019 is already Mongolia and Viet Nam reported their first outbreaks. Because the virus is highly resistant and because of such abrupt changes in the global epidemiological situation, there are fears that the disease may continue to spread in free from disease areas, such as the United States.

A study recently conducted by the Center for animal health and food safety University of Minnesota (USA) in cooperation with European experts came to the conclusion that in 2018 and 2019, the risk of ASF in the States by smuggling of pork in the Luggage of air passengers has increased dramatically (183%) compared to previous periods.

The results also show that it is likely (probability ~ 1) that currently the virus enters a U.S. airport in the Luggage of air passengers to customs inspection, which indirectly confirmed cases by detection of the ASF seized the pork in some airports in Australia and Asia. Probably the risk is significantly reduced after customs inspection. Most of the risk (50%) was associated with the flights from China and Hong Kong, followed by the Russian Federation (27%).

The researchers came to the conclusion that crucial to mitigate the potential impact of the invasion of the ASF in the United States have prevention and early detection. If the disease still gets into the States, because of the need for the imposition of restrictions on movement and trade will be seriously affected local pig.
