["FMD outbreaks occurred on [5 Oct 2016] on 2 cattle farms located in
Bafata, Guinea-Bissau. The Senegalese Agricultural Research Institute,
Dakar (regional reference laboratory) confirmed the diagnosis on [28
Oct 2016]. The laboratory examined 92 sera and a pool of 6 vesicular
fluids collected from the outbreaks. Antibodies against non-structural
proteins were detected in 18 sera, and their reactivity was against
FMDV serotypes O and A (11 animals positive for A and O, 6 animals
positive for O, and one positive for A), while SAT1 and SAT2 antigens
were detected in the pool of vesicular fluids; for this reason it was
not possible to identify the number of animals positive for each
serotype. Source of the outbreak is unknown, and the only sanitary
measure to be applied is vaccination.

"Scarce or no information is available relative to the FMDV serotypes
circulating in this country. The last outbreak reported in the country
was in 2014, while the presence of the disease was still suspected in
2015" (see
<www.fao.org/fileadmin/user_upload/eufmd/docs/FMD_monthly_reports/2016/December_2016.pdf>).

The outbreaks that occurred in October 2016 were not reported to the
OIE until December 2016. According to the final report sent to the OIE
on 26 Jun 2017, the event was resolved March 2017. 1500 bovines were
vaccinated against serotypes O, A, and SAT2 in the Santanto and
Cadjito, Bafata region. See event summary and map at
