title: Detection and genetic characterization of arboviruses and other viruses from mosquitoes collected in Southeastern and Central Senegal, October 2022

description: Mosquito-associated virus distribution and genetic data are incomplete in
 Senegal. This study updates information on virus diversity, distribution,
 and phylogenetic relationships through entomological and molecular
 surveillance. Mosquitoes were collected in October 2022 from 10 districts
 in Senegal, identified morphologically, and tested using qRT-PCR. Positive
 samples were sequenced for genetic characterisation. A total of 42 virus
 isolates belonging to 7 viruses (Bagaza virus (BAGV), Barkedji virus,
 Sindbis virus 5SINV), Usutu virus (USUV), Dezidougou virus, Densovirus,
 and Pestivirus A (PESVA)) were detected in 6 mosquito species (Mansonia
 uniformis, Culex neavei, Anopheles coustani, Cx. cinereus, Aedes aegypti,
 and Ae. vexans). Most detections (92.9%) occurred in mosquitoes from
 ponds. BAGV and SINV were recorded for the first time in southeastern
 Senegal, and PESVA was detected in field-collected mosquitoes for the
 first time. Phylogenetic analyses in the associated article, revealed
 PESVA clustering with strains from Asia and Egypt, BAGV with strains from
 Senegal and Spain, USUV with a Senegalese strain, and SINV with strains
 from Spain and Kenya. This dataset documents new geographic records and
 vector associations for several viruses in Senegal, providing baseline
 information for arbovirus surveillance and risk assessment.

 Description of the data and file structure Mosquitoes were collected in 10
 districts in the Kedougou (Dindefelo, Bandafassi, Fongolimbi, Dimboli and
 Tomboronkoto) and Linguere areas (Barkedji, Dodji, Thiel, Gassane and
 Thiargny) located respectively in southeastern and central Senegal in
 October 2022. Mosquitoes were tested for viral infection. ### Files and
 variables #### File: Database_Diallo_et_al._2025.csv **Description:** This
 dataset contains detailed records of mosquito collections conducted in
 October 2022 across ten districts in Senegal, including species
 identification, collection sites, habitat types, and viral screening
 results. The dataset can be used to examine mosquito species distribution,
 virus–vector associations, and habitat-specific virus occurrence. All data
 are openly available without restriction for research, surveillance, and
 educational purposes. ##### Variables * Districts : districts where
 mosquitoes were collected (Bandafassi, Barkedji, Dimboli, Dindefelo,
 Dodji, Fongolimbi, Gassane, Thiargny, Thiel, Tomboronkoto) * Habitat:
 habitat in which traps wet set (human dwellings, animal shelters, Ponds) *
 Trap: traps used to collect mosquitoes * Genera: Mosquito genera collected
 and included in each pool * Species: Mosquitoes species included in each
 pool * Number: Number of mosquitoes specimens in each pool * Statut:
 physiological status of the mosquitoes of each pool * Sex: include the sex
 of the mosquitoes of each pool * Virus detected: include virus detected in
 each pool. Blank cells indicate negative pools ## Code/software the
 database was saved as csv. It could be opened using Excel.
