Is the increase of wildlife diseases in your area a growing cause for concern?
Since the first report on June 30, Virginia has experienced an outbreak of hemorrhagic disease among white-tailed deer. The illness, which is spread by small biting midges, has resulted in confirmed deaths in Orange County and Alexandria.
Why it matters
Abnormally dry summer weather created mud flats that served as breeding grounds for midges, leading to an increased incidence of the often-fatal virus. The disease poses no risk to humans or pets in the area.
The Virginia Department of Wildlife Resources currently receives 4 to 5 reports of suspected cases per day. Officials have officially confirmed 2 deer deaths from the disease across the state.
The players
Virginia Department of Wildlife Resources
This state agency manages wildlife and inland fisheries and operates the Wildlife Helpline for the public.
The details
Infected deer exhibit symptoms including lethargy, breathing difficulty, and swollen heads. Reports of suspected cases have originated from York, James City, Gloucester, Middlesex, and Botetourt counties.
Timeline
The first report of potential hemorrhagic disease occurred on June 30.
Sightings of symptomatic deer were reported in early August.
The DWR issued a news release in early September.
Midge activity is projected to end in October or November.
Health Landscape
This outbreak is being monitored against the historical benchmark of the 50% deer population mortality rate recorded in 2014. The data helps biologists track how environmental shifts influence the long-term prevalence of the virus in local wildlife.
While the disease poses no risk to humans or pets, residents should report sightings of lethargic deer with breathing difficulties to authorities. Members of the public can contact the DWR Wildlife Helpline at 855-571-9003 to report potential cases.
The takeaway
Wildlife officials suggest that the outbreak is tied to specific weather patterns that favor midge reproduction. Residents should remain aware that the virus is naturally occurring and requires no intervention for human health safety.
What happens next
The spread of the virus is expected to conclude in October or November when a freeze effectively kills the midge population.
