The presence of ASF is notified to the OIE by its Members through the Six-monthly reports (as sufficiently stable) or through Immediate Notifications and Follow-up reports (when considered as an exceptional event). In 2018, this disease was notified through the six-monthly reports in 3 countries in Europe (Estonia, Italy and Lithuania) and 13 countries in Africa. This report presents an overview of the events notified through the OIE’s Immediate Notifications and Follow-up reports. This information is publicly available. A classification of the affected population (by backyard and farm swine and wild boar) was made considering their different roles in the epidemiology of the disease. As of January 2019, the format and methodology of this report have been updated to display the information in a more simple and clear way.
