Can these wild Florida monkeys give you herpes? Here’s where they’ve been seen

Nearly 200 rhesus macaques at Silver Springs State Park

In this Friday, Nov. 10, 2017 photo, a rhesus macaques monkey observes kayakers as they navigate along the Silver River in Silver Springs, Fla. Wildlife managers in Florida say they want to remove the roaming monkeys from the state in light of a new study published Wednesday, Jan. 10, 2018, that finds some of the animals are excreting a virus that can be dangerous to humans.

MARION COUNTY, Fla. – When it comes to Florida’s wildlife, the first animals that come to mind are usually alligators, sharks or manatees.

However, monkeys are also a staple within Central Florida, according to the Florida Fish and Wildlife Conservation Commission.

These monkeys — called “rhesus macaques” — were originally brought to Florida by the manager of a glass-bottom boat operation, who released six on an island in the Silver River to attract tourists.

However, the monkeys swam away from the island into the surrounding forest, breeding and increasing their numbers over the years.

While the population of monkeys in the Silver Springs State Park has reached as high as 400 at some points, trapping and removal efforts have kept them from getting out of hand. As of 2015, the FWC reported that there were around 190 inside the park.

Nowadays, these monkeys can be found throughout the state, though the FWC says that these sightings likely stem from the group of monkeys at Silver Springs.

Aside from environmental concerns, these monkeys pose a threat to public health, as rhesus macaques in Florida have tested positive for herpes B.

The CDC states that this viral infection is extremely rare, but it can lead to severe brain damage or even death. The virus can be transmitted by these monkeys through bites, scratches or contact with bodily fluids.

In addition, these monkeys may become aggressive when fed by people, so the FWC passed a rule in 2018 prohibiting locals from feeding any wild monkeys in the state.

According to the FWC’s rhesus monkey tracker, the following counties have had credible sightings of these monkeys outside of the core population:

In Central Florida alone, Marion, Seminole and Lake counties saw a marked increase in rhesus macaque sightings over the past two years, the data shows. Just last year, there were six reported sightings out of Lake County alone, many of which were in and around Clermont.

The FWC provides these tips for rhesus macaque encounters:

  • Never approach or offer food to wild monkeys
  • If a monkey is encountered, keep children close and pets leashed
  • Dispose of uneaten food and garbage in closed trash containers
  • If bitten or scratched by a wild monkey, immediately wash the wound and seek medical attention. Call the National B Virus Resource Center for emergency information at (404) 413-6550.
  • If you observe a wild monkey that poses a threat to people, call the FWC’s Wildlife Alert Hotline at (888) 404-3922
  • Any rhesus macaque observations seen outside of the core population near Silver Springs should be reported by calling the Exotic Species Hotline at (888) 483-4681 or by clicking here
