Resum
The surveillance for West Nile virus (WNV) in Catalonia (northeastern Spain) has consistently detected flaviviruses not identified as WNV. With the aim of characterizing the flaviviruses
circulating in Catalonia, serum samples from birds and horses collected between 2010 and 2019
and positive by panflavivirus competition ELISA (cELISA) were analyzed by microneutralization
test (MNT) against different flaviviruses. A third of the samples tested were inconclusive by MNT,
highlighting the limitations of current diagnostic techniques. Our results evidenced the widespread
circulation of flaviviruses, in particular WNV, but also Usutu virus (USUV), and suggest that chicken
and horses could serve as sentinels for both viruses. In several regions, WNV and USUV overlapped,
but no significant geographical aggregation was observed. Bagaza virus (BAGV) was not detected in
birds, while positivity to tick-borne encephalitis virus (TBEV) was sporadically detected in horses
although no endemic foci were observed. So far, no human infections by WNV, USUV, or TBEV have
been reported in Catalonia. However, these zoonotic flaviviruses need to be kept under surveillance,
ideally within a One Health framework.
