Between August 24 and August 28, ASF was found in 25 wild boars, including four in Koceni municipality in north-eastern Latvia, and three in each Valka and Rujiena municipalities, also in north-eastern Latvia.
So far this year PVD has found ASF in 636 wild boars in 111 districts in the territory of 37 municipalities as well as in one town in eastern Latvia. The total number of confirmed ASF cases among wild boars in Latvia since June 2014 is 853.
The last time a domestic pig tested positive for ASF in Latvia was on August 25 this year but the spread of the disease among domestic pigs now has slowed down compared to wild boars.
African swine fever is an extremely dangerous and contagious virus infection affecting pigs. If an infected pig is found in a farm all pigs in the particular farm have to be culled, which means big losses for farmers.
It first arrived in Latvia in June 2014, believed to have been carried across the border from Belarus by wild boar. A series of quarantine zones and culls in the months since have failed to stop its advance across Latvia and into Estonia.
Previously, the Latvian government, at Europe's behest, approved amendments in regulations on measures to prevent and eradicate the disease.
