[The original version of the report above lists sanitary measures to be taken in case of a suspected outbreak. Outbreaks registered in Tobruk, Bayda, and Al Marj have been reported to WOAH on 8 and 9 Mar 2023; see follow-up reports at https://wahis.woah.org/#/in-event/3835/dashboard. Information regarding the topotype registered is anticipated. This information is crucial for the adaptation of the vaccination strategy in Libya and its neighboring countries. - Mod.SF
Historically, Libya encountered numerous FMDV incursions. Overall, 3 different serotypes have circulated: O, A, and SAT2. Type O is the most prevalent serotype, followed by serotype A. In 2012 an FMDV O/EA-3 topotype was reported, co-circulating with ME-SA topotype PanAsia-2 lineage ANT-10 sublineage; however, those EA-3 strains were more closely related with eastern Africa strains (that is, Ethiopia and Sudan) while the 2019 incursion was more correlated with strains circulating in the Maghreb from a western Africa route (https://doi.org/10.3390/ani12223198). FMDV SAT2 was last reported from Libya in 2003 and 2012; this serotype has recently been reported from Jordan, Iraq, and Turkey. - Mod.AS
