Emerging infectious diseases have inflicted a significant health and socioeconomic burden upon the global population governments worldwide. West Nile virus, zoonotic, mosquito-borne flavivirus, was originally isolated in 1937 from febrile patient Province of Uganda. It remained confined mainly to Africa, Middle East, parts Europe Australia until 1999, circulating an enzootic mosquito-bird transmission cycle. Since beginning 21st century, new, neurotropic, more virulent strain human outbreaks initially occurring North America later expanding South South-eastern Europe. 2010, when first epidemic recorded Greece, annual incidence has fluctuated significantly. A variety environmental, biological factors been globally addressed as potential regulators anticipated intensity rate; circulation within zoonotic reservoirs, recruitment adaptation new potent arthropod vectors, average winter summer temperatures, precipitation during early months, factors, such emergence progression urbanization development densely populated areas association with insufficient policy measures. This paper presents review socioenvironmental influencing dynamics epidemics virus (WNV) cases one highest-ranked European countries terms incidence. To date, WNV remains unpredictable opponent is also case other emerging diseases, forcing National Health systems develop response strategies, control number infections, shorten duration epidemics, thus minimizing impact on material resources.

Emerging infectious diseases are a major threat to biodiversity and an important public health issue. West Nile virus (WNV) is emerging vector-borne zoonotic arbovirus that currently broadening its distribution in Europe. The evidence of WNV circulating resident migratory species has implications for both animal health, should therefore be studied depth. An integrated surveillance program, namely birds, essential reducing the risk infection human populations within One Health principles. In present study, wild birds admitted wildlife rehabilitation centres Portugal were sampled. Two-hundred eight blood samples assayed serologically antibodies WNV, by using commercial ELISA kit. overall seroprevalence 19.6% (95% confidence interval [CI]: 13.7-26.7%) was observed. Antibodies detected 13 (35.1%) different birds. Accipitriformes (26.7%; 95% CI: 18.5-36.2%) Strigiformes 14.6-42.0%) orders with highest recorded. There no statistically significant differences (p = 0.725) between geographical regions (NUTS II) studied, but difference 0.017) found gender (male: 34.4%; female: 4.8%). A higher adults (32.1%) compared juvenile (9.3%) 0.014), age considered factor (odds ratio 1.4; 0.5–4.0). More epidemiological studies needed Portugal, since actual spread throughout country unknown.

Abstract The diversity and abundance of vectors are essential parameters in the transmission dynamics West Nile virus (WNV) between its avian reservoirs clinically susceptible mammalian species. Knowing determinants vector could be thus useful preventing fever (WNF) cases associated socio‐economic impact. We designed a survey at wildlife–livestock interface to test hypothesis that variations environmental favourability anthropized wild scenarios modulate WNV risk. In continental Mediterranean region where WNF has recently emerged, we selected nine sampling sites allocated three areas every site with decreasing gradient interaction: A 1 —a horse farm interaction is maximal; 2 zone intermediate 500–1000 m from farm; 3 —an entirely low 1–5 km farm. At fortnightly frequency, estimated mosquito each 27 study May–December 2018 April–July 2019. bird mammal abundance, collected meteorological information characterised habitat scale. Thereafter, studied Culex spp., pipiens sensu lato (s.l.)

Our results indicate environments favourable for circulation maintenance, especially rural settings such as farms. These will have an impact on risk prediction emergence environments.

We analyzed West Nile Virus (WNV) exposure from 1,222 blood donors during 2017-2018 an area of south-central Spain. Results revealed WNV seroprevalence 0.08% (95% CI 0.004%-0.4%) in this population. Our findings underscore the need for continued surveillance and research to manage infection region.
