A classification of the affected population (by backyard and farmed swine, and wild boar) was made considering their different roles in the epidemiology of the disease.
Hong Kong
1 IN: notifying 1 new outbreak in farmed swine.
Indonesia
1 FUR: notifying 443 new outbreaks in backyard swine.
Korea (Rep of):
3 FUR: notifying 66 new outbreaks affecting wild boar.

The impact of African swine fever in Asia since 2018 is detailed in table 1. It shows the total outbreaks, administrative divisions affected and cumulative number of animal losses (backyard and farmed swine) by country.
NOTE: The losses are calculated based on the sum of dead and culled animals in the infected farm or backyard premises notified within the outbreaks. However, the OIE does not collect quantitative information on additional control measures applied in response to the outbreaks (for example preventative culling in a zone around an outbreak.
