Two more cases of African swine fever (ASF) have been confirmed in wild boars in the eastern German state of Brandenburg, with one found outside the area of the first discoveries, the federal agriculture ministry said on Wednesday.

One new discovery was confirmed in the Maerkisch-Oderland district in Brandenburg outside of the area close to the Polish border where the first cases were found, the ministry said. The second case was inside the original area, it added.

"The state of Brandenburg must now undertake an appropriate adaptation of the existing protection zones and protection measures to prevent a further expansion of the disease," the ministry said. The new discoveries bring total confirmed cases to 38 since the first on September 10. All were in wild animals with no farm pigs affected, the ministry said.

The Friedrich-Loeffler scientific institute confirmed the latest animals had ASF, the ministry said. More cases in wild boar have to be expected as the disease is highly infectious, it said. 

The German government is considering aid to farmers after prices fell following the discovery of ASF in wild animals in the country, Germany's agriculture minister Julia Kloeckner said on Friday.

On September 10, German officials confirmed the first case of African Swine Fever in a wild boar found near the Polish border. 

ASF is not dangerous to humans but fatal to pigs and the mortality rate of the virus is extremely high. Some countries banned imports of German pork in September to slowdown the spread of the virus after the first case was confirmed.
