The Florida Department of Health confirmed nine cases of Eastern Equine Encephalitis (EEE), also known as Triple E, in Brevard, Volusia, and Orange counties in 2026. Sentinel chickens in Orange County tested positive for the virus last week, marking the first confirmed detection in Central Florida this year. Health officials say the findings highlight the growing threat of mosquito-borne illnesses as summer heat and humidity increase mosquito activity.
The virus, which has no specific treatment or vaccine, has infected at least one horse in Volusia County since March. Officials stress that residents must take action to reduce mosquito breeding grounds. Draining standing water, screening windows and doors, and maintaining yards are key steps. In Brevard County, Emily Browder and her friends rely on natural repellents like peppermint and lavender oil to avoid bites, though they admit using DEET when necessary.
Browder, who lives in Cocoa Beach, said the area has faced mosquito infestations in past summers. "We’ve had summers where it’s just been a real infestation," she said. "Now that Triple E is here, protection is a must." Health officials warn that the virus can cause severe illness, including encephalitis, with a high fatality rate in humans.
The Florida Department of Health has been monitoring the situation closely. Sentinel chickens, placed strategically across the state to detect mosquito-borne diseases, have confirmed the presence of EEE in Central Florida. Officials say the risk is heightened during the summer months, when mosquitoes are most active. They urge residents to avoid areas with high mosquito populations and to use repellent consistently.
With no cure for Triple E, prevention remains the only defense. Health officials are working to educate the public on reducing mosquito habitats and using protective measures. As the summer season progresses, the threat of EEE underscores the need for vigilance in communities across Brevard and surrounding counties.
