In 2019, we conducted a study to assess the situation of African swine fever in Hai Duong
province. The studied results showed that the epidemic appeared in 12/12 districts and cities
in 255 communes, 1,155 villages, destroyed 392,359 pigs in 27,412 farms/households. The
percentage of positive samples was 85%. The percentage of commercial pigs was destroyed
to be 58.22% and this rate in the piglets was 9.28%. There were 6/9 risk factors related to
the spread of ASFV in the concentration farms at the significance level (P < 0.05), of which
there were 3 main factors associated with the spread of ASFV, such as: the distance from the
pig barns to the living place of workers was less than 200m, transportation of feed and other
livestock products into and out of the farms was not transferred to other truck at the farm gate,
and the origin of piglets was not clear.
