Flaviviruses of the Japanese encephalitis virus (JEV) antigenic complex, including West Nile virus (WNV), are recognized as emerging and reemerging pathogens. Circulation of flaviviruses has been recently detected in different mosquito and vertebrate species in several European countries. A serosurvey study was carried out to evaluate the circulation of WNV and other flaviviruses of the JEV antigenic complex in different wild bird species in Spain between 2006 and 2009. Seropositiviy against…

The results presented here evince the need for permanent surveillance for emerging flaviviruses in Brazil, as well as for a contingency policy in the case of human/animal outbreaks, particularly in high-risk areas.

Exposure to West Nile virus and tick‐borne encephalitis virus in dogs in Spain

The seropositivity obtained indicates widespread, but not homogeneous, distribution of WNV and TBEV in dogs in Spain, and could be a complementary way of monitoring the activity of emerging flaviviruses in Spain.

Serological evidence of co-circulation of West Nile and Usutu viruses in equids from western Spain.

It is demonstrated that WNV and USUV are circulating in regions of western Spain and it is important to improve the surveillance programmes of public health to detect undiagnosed human cases and to establish a vaccination programme in equids herds in these regions.

Circulation of a Meaban-Like Virus in Yellow-Legged Gulls and Seabird Ticks in the Western Mediterranean Basin

This study shows that gulls in the western Mediterranean Basin are exposed to a tick-borne Meaban-like virus, which underscores the need of exploring the spatial and temporal distribution of this flavivirus as well as its potential pathogenicity for animals and humans.

High Prevalence of West Nile Virus in Domestic Birds and Detection in 2 New Mosquito Species in Madagascar

This study showed that WNV circulates in Madagascar amongst domestic birds and mosquitoes, and highlights the utility of poultry as a surveillance tool to detect WNV transmission in a peri-domestic setting.

Wild Birds in Romania Are More Exposed to West Nile Virus Than to Newcastle Disease Virus.

Findings provide evidence that wild birds, especially resident ones, are involved in local West Nile and Newcastle disease enzootic and epizootic cycles that may allow virus maintenance and spread and also enhance the chance of new outbreaks.

Monitoring of the West Nile virus epidemic in Spain between 2010 and 2011.

The results showed active WNV circulation several months before the first outbreak was reported in horses, and the seropositivity found in municipalities where clinical cases were not reported indicates a higher geographical dissemination of the virus.

Serological Evidence of West Nile Virus in Wild Birds in Bangladesh

These study findings recommend continued surveillance for early detection and to better understand the epidemiology of WNV and other flavivirus circulation in both birds and mosquitoes in Bangladesh.

Seroprevalence and risk factors associated to West Nile virus in horses from Andalusia, Southern Spain.

Serosurvey of West Nile virus in equids and bovids in Spain

The WNV-specific antibodies found in horses in Donana are in agreement with the previous findings in wild birds in the same area, thus supporting the existence of WNV activity in this region of southern Spain.

Serologic survey of birds for West Nile flavivirus in southern Moravia (Czech Republic).

The results indicate that WNV activity in southern Moravia was limited during 2004-2006, and 13 of 391 wild birds had specific antibodies to WNV.

West Nile Virus: An Overview of Its Spread in Europe and the Mediterranean Basin in Contrast to Its Spread in the Americas

The WN virus is now well established in the New World, and it disseminates rapidly, so enhanced surveillance of WN infection in humans, horses, birds, and vectors may reveal the presence of the virus in different locations.

Prevalence of West Nile virus neutralizing antibodies in Spain is related to the behavior of migratory birds.

It seems that the risk for introduction of strains of WNV from Africa by migratory birds merits further field and experimental studies in Spain, as seroprevalences assessed in resident birds suggest a low level of W NV circulation in the studied locality.

Anticuerpos frente a virus West nile y otros virus transmitidos por artropodos en la poblacion del Delta del Ebro

The results and those obtained previously in other parts of the Iberian Peninsula suggest that the WNV is moving throughout the human population in the areas where this risk is found to exist and periodically gives rise to epidemic outbreaks.

Serologic survey of potential vertebrate hosts for West Nile virus in Poland.

Data indicate a significant trace that demands verification of WNV activity in Poland, and one black-headed gull had neutralizing antibodies for the Usutu Flavivirus, the first case recorded in Poland.

Low West Nile virus circulation in wild birds in an area of recurring outbreaks in Southern France.

The detection of a seroconversion in one bird, as well as the detection of seropositive birds in all years of monitoring, including juveniles, indicate a constant annual circulation of WNV at a low level, including in years without any detectable emergence of WN fever in horses or humans.

Serologic evidence of West Nile virus infections in wild birds captured in Germany.

Despite a relatively high percentage of stork nestlings with antibodies, no viral genomes were detectable by polymerase chain reaction and the prevalence of antibodies to WNV in migrating birds wintering in Africa or southern Europe is comparatively low.

Serological Evidence of USUTU Virus Occurrence in North‐Eastern Italy

Evidence of the circulation of USUV in north‐eastern Italy is provided by a sentinel chicken in a flock of 20 animals located within the Ravenna province seroconverted to USUV reaching neutralizing titres up to 1 : 5120.

Emergence of Usutu Virus in Hungary

The nearly complete genomic sequence of one Hungarian USUV strain was determined; it was found to share 99.9% identity with the strain that has been circulating in Austria since 2001, which indicates that the US UV strain responsible for the blackbird die-off in Budapest most likely spread from Austria to Hungary.
