  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 Background :  The Liao ning virus (LNV), belonging to the genus Seadornavirus within the family Sedoreoviridae , is a mosquito-borne virus . It was originally isolated from Aedes dorsalis mosquitoes in China . The original LNV strain, LNVS-NE97-31, was reported to infect several mammalian cell lines and cause hemorrhagic symptoms in mice . Subsequently, another LNV strain, LNV NSW B115745, was isolated from Australian mosquitoes ; it was reported to exhibit insect-specific infection. Materials and Methods :  Virus isolation was performed on mosquitoes collected in northern Hokkaido, Japan, in 2022 . The isolated virus was subjected to genomic and growth kinetics analyses. Results :  A LNV strain was isolated from Aedes vexans mosquitoes . Genomic sequencing and phylogenetic analysis revealed the new strain as 22WN03, and it formed a robust clade with the original Chinese strain, LNVS-NE97-31. Growth kinetics analysis did not reveal any mammalian or avian cell lin...
