Circulation of Zoonotic Arboviruses in Equine Populations of Mallorca Island (Spain)

Abstract : The presence of major arbovirus vector species, climate change that promotes the expansion and increase of their populations, and potential animal reservoirs mean that vector-borne diseases represent a significant health risk for Mallorca's inhabitants. Microbiological monitoring of circulating arboviruses, particularly flaviviruses causing encephalitis, was initiated using domestic horses from localities near wetlands as “sentinel” hosts. A total of 291 blood samples were taken from 172 horses between 2011 and 2012, using paired samples to highlight seroconversion events. A multiplex immunoassay and confirmatory reference serological assays were used to screen sera for immunoglobulin G antibodies against West Nile (WNV), Usutu (USUV), and tick-borne encephalitis (TBEV) viruses. The seroprevalence was 6.4% (confidence interval [95% CI] 3.2%−11.0%) for WNV, 1.2% (95% CI 0.1%−4.1%) for USUV, and 0.6% (95% CI 0.0%−3.2%) for TBEV. In addition, eight horses (4.6%; 95% CI 2.0%−8.9%) were found positive for unidentified flaviviruses. Seroconversion events were detected for WNV and USUV, reflecting recent arboviral infections. These results highlight the active transmission of zoonotic arboviruses in Mallorca wetlands.
