"An outbreak of FMD type SAT 2 was previously reported in cattle at Kasokeza, Maperera Dip tank, Chikwawa, Southern Region [on 7 Aug 2020]. VP1 sequencing was performed at the OIE Sub-Saharan Africa Regional Reference laboratory (SSARRL) for FMD at the Botswana Vaccine Institute (BVI) on 2 samples and showed that the virus belonged to topotype I" (Source: FAO. 2021.
