The outbreak was reported on Monday after several pigs belonging to Vũ Thanh Tùng and Phạm Ngọc Hưng in Trần Phú Farm Town contracted fevers and died.
The central province of Quảng Trị on Tuesday detected a second outbreak in Commune 5, District 3, Đông Hà City. 28 pigs were culled on Tuesday to stop its spread.
On Monday, an African swine fever outbreak was also reported in the key pig farming province of Đồng Nai.
Trảng Bom District, where the first infected pigs were found, set up two quarantine check-points, demanded a halt on slaughterhouses and sprayed disinfectant at farms and burial sites.
According to the Animal Health Department, in the first four months of this year, African swine fever has wreaked havoc in more than 20 localities across Việt Nam, resulting in the culling of more than 85,000 pigs.
The first case was reported in the northern province of Hưng Yên before the disease spread out to 22 other localities.
In early April, Hà Nội, Hưng Yên and Hải Dương announced that they had successfully contained the disease.
The northern provinces of Hoà Bình and Bắc Kạn became first localities to completely eradicate African swine fever.
African swine fever is a fatal infectious disease caused by a virus which spreads rapidly among pigs. It is not harmful to humans.
The World Organisation for Animal Health revealed that some 20 countries have reported African swine fever since 2017, disposing of more than one million pigs.
The three main causes for the wide spread of African swine fever are unsterilised vehicles and people, feeding leftover food to pigs and the transportation of infected animals.
Việt Nam is one of three Asian countries suffering from African swine fever, along with China and Mongolia. — VNS
