Surveillance in NUTS 3 areas with at least one ASF notification during the reporting period	No cases of ASF in wild boar nor outbreaks in domestic pigs were reported during the reporting period.
New developments of the epidemic in the reporting period	Belgium is officially free from African swine fever for all Suidae since 1 October 2020 in accordance with Chapter 15 of the OIE Terrestrial Code.
Specific prevention and control measures implemented during the reporting period	Measures implemented after regaining Freedom of Disease (FOD) status 1. Preventive measures and surveillance in domestic pigs Measures are carried out by the Federal Agency for the Safety of the Food Chain (FASFC) in the whole country and the Belgian legislation has been adapted. Several measures that were put in place during the crisis (enhanced passive surveillance, strict biosecurity procedures and active surveillance) have been maintained. The annual evaluation of the biosecurity measures in each pig holding (BioCheck) is mandatory since January 2021. Restocking of pig farms in the former infected area is allowed since January 2021. 2. Preventive measures and surveillance in wild boar Measures are carried out by the regional authorities (Public Service of Wallonia). 2.1. From the early days of the outbreak, infected forests had been completely closed for walking and professional activities. From 2020 onwards, the bans were progressively lifted by maintaining biosecurity rules. Free access to the forest was allowed in April 2021 with respect to the forestry code. 2.2. Active and scheduled search for dead wild boar was still organised by the regional authorities over the two former ASF zones until end of March. From April 2021, the search effort was maintained until end of August but with a lower search rate associated with fences inspection activities (A. Licoppe, personal communication). Places where alive wild boar were detected by the network of cameras were targeted for search. 2.3. All fences (approximately 300 km in and around the two former ASF zones) were maintained, checked and repaired during the reporting period. The three carcass collection centres set up at the beginning of the crisis remained functional until end of March 2021. From April 2021, the veterinary teams kept open only the main centre in Virton. 2.4. The regional authorities maintained the depopulation measures in the two former ASF zones during the reporting period and the regional legislation was adapted (Walloon government decree, July 2020). Night shooting and trapping were suspended on 31 August 2020 in anticipation of the hunting season. The results of driven hunts were poor for different reasons, including low densities of wild boar, lack of motivation of the hunters and the COVID‐19 crisis. In mid‐November 2020, night patrols were re‐launched in the agriculture area. Both night shots and trapping were intensified in February/March and stopped from 1 April 2021. Night shooting could be re‐activated by the regional authorities in case of resurgence or to impose the active surveillance. In conclusion, during the reporting period (September 2020 to August 2021), 280 wild boar were analysed, and all virological results were negative (Sciensano, B. Cay, personal communication).
