[The foot-and-mouth disease (FMD) SAT-2 event reported in the above immediate notification had started in Jordan at the latest in early January 2023. According to Jordan's media of 8 Jan 2023, dairy cattle breeders in the Al-Dulail (Dhlail) area, Zarqa governorate, complained about FMD seriously affecting their cattle, including mortality, despite being vaccinated earlier (20230110.8707716). The vaccine was supposed to protect against FMD virus serotype O, a virus which reportedly had been circulating in Jordan since December 2021. The breeders called on the concerned authorities to open an investigation to find out the reasons for the increase in infections among their herds despite receiving the vaccinations. Eventually, the current disease in Dhlail, which is Jordan's main dairy cattle center, has been found to be caused by a newly introduced exotic FMD strain, serotyped SAT-2. A similar strain has been recently circulating in Iraq. Consequently, the Ministry of Agriculture published, through Jordan's News Agency (Petra), on 5 Feb 2023 that the results of the FMD virus analysis at the Faculty of Veterinary Medicine/University of Science and Technology, Irbid, revealed the emergence of a new strain of the virus called SAT-2, "which was not previously registered in Jordan." The ministry added in a statement that this strain was registered in Iraq, Saudi Arabia, Kuwait, and Ethiopia, indicating that "the results of the analysis, conducted by Dr. Mustafa Ababneh (Associate Professor of Veterinary Virology), were verified by Pirbright" (https://tinyurl.com/28ax5vuv).
The genotyping results of the Jordanian and Iraqi strains are expected to assist the studies into the virus source, its national and transboundary spread routes, and choice of the matching vaccine(s). Ideally, its species affinity (cattle, buffalo, sheep, goat, pig) will be studied as well.
So far, the SAT-2 strain in Jordan seems to be restricted to the Dhlail region. According to available information, its spread in Iraq is wider, with water buffalos and cattle seriously affected. According to Petra News Agency, on 15 Feb 2023 Jordan's Ag Ministry decided to continue the precautionary measures in the vicinity of the epicenter of infection, addressing the Ministry of Local Administration to instruct the opening of livestock markets in the southern governorates (Karak, Tafila, Maan, Aqaba) from Friday, 17 Feb 2023. - Mod.AS
