Sand fly-associated phlebovirus with evidence of neutralizing antibodies in humans and dogs in Kosovo.

ABSTRACT: The Balkan Peninsula is a hotspot for sand fly-borne phleboviruses (SbPVs), yet Kosovo had no confirmed viral detection invectors despite serological evidence of human and animal exposure. This study reports the discovery, genetic characterization, and seroprevalence of a novel phlebovirus, Grapi virus (GRPV), in Kosovo. Entomological surveys (2022-2023) collected 3,575 sand flies across seven districts. Morphological and molecular identification revealed Phlebotomus perfiliewi as the dominant species. Pan-phlebovirus RT-PCR screening identified GRPV in seven pools. Complete genome sequencing confirmed its tripartite genome, sharing 97.55-98.70% nucleotide identity with Bregalaka virus, classifying it within the Phlebovirus adanaense species. Phylogenetic analysis revealed segment-s
