African Swine Fever spread across Asia, 2018-2019

Information on the locations and dates of AFS outbreaks throughout Asia was gathered from the OIE. Immediate Notifications and Follow-up reports were accessed from the Report Archive of the World Animal Health Information Database (WAHIS) Interface.[1] Reported ASF outbreaks were selected if they were located in an Asian country between 1 August 2018 and 31 December 2019. For each report, the following information was extracted: date of report, outbreak start date and end date (if applicable), location (latitude/longitude and by name), unit type, number of susceptible animals, number of cases, deaths and number of animals killed and disposed of. Reports were only included for domestic pig populations; reports of occurrence in wild boar were excluded. Data were imported into Microsoft Excel 2016 and all reports were combined into a single dataset for further analysis. Error checking was performed by ensuring logical values were recorded for each data point and by random selection of 5% of the data to manually check against the original reports.
