The highest mosquito density was observed in pigpens (26.0 mosquitoes\/light trap-night). The JEV antibody positivity rate in piglets began to rise in June, peaked in September (83.33%), and lagged two months behind the peak mosquito density (June\u2013July). A significant temporal correlation was found between piglet antibody positivity and mosquito density (*p* &lt; 0.05). Phylogenetic analysis showed that all mosquito-derived JEV strains belonged to genotype I (GI), with 15\u201317 amino acid mutations in the E gene compared to the vaccine strain SA14-14-2.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>\n                      <jats:italic toggle=\"yes\">Conclusion:<\/jats:italic>\n                    <\/jats:title>\n                    <jats:p>There is a persistent JEV transmission risk in Hunan Province.
