Public health: mosquito surveillance finds Aedes albopictus in Louisa County for second year; overall mosquito counts rose in 2024
Summary
Public health staff reported detection of Aedes albopictus (a species that can carry chikungunya and dengue) for a second consecutive year and said 2024 mosquito collections were substantially higher than 2023; no human disease increases were reported.
Louisa County public-health staff reported to the board that routine mosquito surveillance detected Aedes albopictus for the second year running and that the county's mosquito collections in 2024 were substantially higher than in 2023.
Leah (public-health staff) said the county places traps multiple times weekly during mosquito season and submits specimens to the state for species identification and disease testing. The Aedes albopictus species can carry diseases such as chikungunya and dengue; public-health staff said two albopictus mosquitoes were detected during 2024 surveillance and that presence suggests the species is established locally. The staff said they are not currently seeing an increase in human disease but will continue monitoring trends.
Leah also reported public-health budget and program items: the department submitted a budget with a 3% increase to be considered in upcoming hearings and continues to process home-care admits and grants. No immediate public-health actions were taken by the board at the meeting.
Public-health staff asked supervisors whether they had questions and noted plans to continue surveillance and to submit grant applications and budget materials on schedule.
