Europe
In Europe, a targeted surveillance program is continuing. Often, a single case in wild boar is notified as a single outbreak, and is usually resolved immediately.
Poland lost 33,840 animals in April, and the disease moved a considerable distance in the east of the country, getting closer to neighboring countries.
Asia
