Marion County strangles quarantine: Florida's 30th case of 2026, 10 horses exposed

The Equine Disease Communication Center (EDCC) posted a strangles alert for Marion County, Florida, dated November 9, 2026. It lists one confirmed case, two suspected cases and 10 exposed horses at a private facility, with an official quarantine. The alert's comment calls it "the 30th confirmed case of strangles for Florida in 2026." Its source is the Florida Department of Agriculture and Consumer Services (FDACS). Read the alert itself: EDCC alert 5417.

Marion County is the Ocala horse country. We checked the EDCC pages on November 15, and everything below is as of the dates on the alerts, not a live count.

The two alerts

The West Nile alert is EDCC alert 5416. Both name FDACS as the source.

What the alerts do not say

• Dates beyond the alert date. EDCC notices carry one date. They do not give the onset date or the date a laboratory confirmed the case, so we cannot say when the horse became sick.
• Where. EDCC says it does not name specific premises, only the county. Neither alert names a farm, show, sale or event.
• How the 10 exposed horses are doing. "Exposed" and "suspected" are not confirmed cases, and the alert gives no later update. The total could change, and we have not added to it.
• The statewide total. The "30th" and "5th" figures are the ordinal numbers written in the alert comments. They are not a running count we verified case by case.

Background from EDCC

EDCC's strangles page describes the disease as highly infectious, spread by direct horse-to-horse contact and by contaminated surfaces. It gives the incubation period as 3 to 8 days, with fever often appearing 24 to 48 hours before other signs, which can include swollen lymph nodes under the jaw and a thick nasal discharge. It says affected horses should be isolated and biosecurity increased, and that treatment decisions belong to a veterinarian.

West Nile virus is different: it is spread by mosquitoes, not from horse to horse. EDCC's West Nile page says there is no cure, that supportive care is used when signs appear, and that vaccinated horses get a booster each year, with more frequent boosters recommended where mosquito season runs year-round.

What horse owners and show managers can do

If a horse has a fever, nasal discharge or swelling under the jaw, call your veterinarian before moving it or trailering it to a barn or show. Your veterinarian, or the state veterinarian's office, can tell you what applies to your barn. That is the advice we can responsibly give; we are not offering treatment guidance.
