A horse found near Wire Road and Jaws Lane in Aiken tested positive for rabies, exposing 13 people who have since been referred to their health care providers. The South Carolina Department of Public Health confirmed the horse had rabies, marking the seventh animal to test positive in Aiken County this year.
Testing Confirmed Days After Exposure
The horse was submitted for testing at the South Carolina Department of Public Health laboratory on August 18, with confirmation of rabies coming the next day, according to Post and Courier. State health officials confirmed the horse was one of three animals that tested positive for rabies in different South Carolina counties around the same time, alongside a raccoon in Charleston County and a skunk in Anderson County. Statewide, 2026 has already seen 72 confirmed rabid animal cases.
Aiken County has had a rough stretch with rabies vectors this summer. A fox tested positive for rabies in the county in June, and just two weeks before the horse case, a bat and a fox both tested positive in separate parts of the county, exposing one person and one pet, according to the South Carolina Department of Public Health.
Why One Horse Can Expose So Many People
Thirteen exposures from a single animal might sound extreme, but rabies exposure can occur when infected saliva contacts fresh wounds or mucous membranes. People can be exposed without ever being bitten themselves if infected saliva reaches those areas.
The American Association of Equine Practitioners classifies rabies as a core vaccine for horses, citing its 100% mortality rate in equines and the significant public health risks it poses to handlers, but its guidelines have no force of law. Yet South Carolina's Rabies Control Act legally mandates rabies vaccinations only for dogs, cats, and ferrets — not for horses or other livestock, despite strong recommendations from state public health officials. South Carolina law requires pets to be revaccinated at a frequency that provides continuous rabies protection, but no equivalent legal requirement exists for horse owners.
Officials Urge Vaccination as Prevention
“Rabies vaccination is one of the easiest and most effective ways to protect people, pets, and livestock from rabies,” Terri McCollister said in a media release. “Keeping your pets and livestock current on their rabies vaccination is a responsibility that comes with owning an animal,” McCollister added.
Post-exposure prophylaxis administered shortly after contact with a rabid animal is nearly 100% effective at preventing clinical rabies in exposed humans, according to the Centers for Disease Control and Prevention. That treatment efficacy is likely why the 13 exposed individuals in Aiken County were promptly referred to their health care providers rather than facing a longer wait for guidance.
A Recurring Pattern in South Carolina Livestock
The Aiken County horse's vaccination status and the specific wildlife vector that may have bitten it remain unclear.
The pattern of livestock-driven mass exposures isn't limited to horses, either. Hoodline previously reported that a rabid goat sent four people scrambling for shots on public trails in York County last month, underscoring that domestic livestock cases in South Carolina can trigger multi-person human medical exposures.
Aiken's Equestrian Economy Raises the Stakes
The case carries extra weight in Aiken County, within a statewide horse industry that contributes nearly $2 billion annually, per the South Carolina Department of Agriculture. A single infected animal can ripple quickly through the local equestrian community.
South Carolina recorded 101 confirmed animal rabies cases statewide in 2025, including three in Aiken County, following 81 confirmed cases out of 15,209 public health investigations in 2024, according to state data reported by the Greenville Journal. The state also launched a centralized online rabies tracking portal in October 2025, with frequent updates on statewide rabies cases.
Anyone who believes they may have had contact with the Aiken County horse or its tack is urged to contact their health care provider. The South Carolina Department of Public Health operates a 24-hour rabies reporting line at (888) 847-0902, option 2, for residents with questions about potential exposures.
