  Abstract Greece is one of the countries in Europe most affected by West Nile virus (WNV), and since 2010, when the virus caused a large outbreak with 197 human neuroinvasive cases , outbreaks occur almost every year. Mosquito surveillance is an indirect sign of virus circulation; therefore, the purpose of the study was the molecular detection of WNV in 45,988 C. pipiens s.l. mosquitoes collected during 2024 in four Regions of Greece and the genetic characterization of the virus strains. WNV was detected in 41 of 1316 ( 3.12% ) Culex spp. mosquito pools . Next-generation sequencing was applied to the WNV-positive samples that had a high viral load . All WNV sequences belong to Cluster B of the sub-lineage Europe WNV-2A presenting a temporal clustering. The WNV infection rates varied highly across the Regions, regional units and months, being higher in Thessaly and Central Macedonia Regions , especially in July and September. All mosquito pools were also tested for Usutu virus (USU...

  Abstract Climate change is increasingly recognized as a major driver of emerging infectious diseases, particularly vector-borne diseases (VBDs), which are expanding in range and intensity worldwide. Europe , traditionally considered low-risk for many arboviral infections , is now experiencing autochthonous transmission of pathogens such as dengue, chikungunya, Zika virus, West Nile virus, malaria, and leishmaniasis . Rising temperatures , altered precipitation patterns , and milder winters have facilitated the establishment and spread of competent vectors , including Aedes, Anopheles, Phlebotomus, and Culex species , in previously non-endemic areas. These climatic shifts not only impact vector survival and distribution but also influence vector competence and pathogen development , ultimately increasing transmission potential. This narrative review explores the complex relationship between climate change and VBDs, with a particular focus on pediatric populations . It highlights h...

Abstract Given recent outbreaks of Oropouche virus in Latin America and >100 confirmed travel-associated cases in the United States , we evaluated the competence of US vectors , including Aedes albopictus, Culex quinquefasciatus, Culex pipiens , and Anopheles quadrimaculatus mosquitoes . Results with historic and recent isolates suggest transmission potential for those species is low .
