Four pigs died on November 20 at a private household in Chernytsia, Rivne region.

The press service of Ukraine's State Service for Food Safety and Consumer Rights Protection reported that the examination of the selected sample of biological material diagnosed African swine fever (ASF).

Some 300 pigs are bred in the village. They all will be killed.

Measures are being taken to localize the disease on the site of the outbreak and prevent the spread of ASF pathogens.

The ASF virus is the causative agent of ASF. The virus causes a hemorrhagic fever with high mortality rates in pigs, but persistently infects its natural hosts, warthogs, bush pigs and soft ticks of the Ornithodoros genus, without any visible symptoms. There is currently no vaccine against ASF.
