Orange County has five dengue cases caught locally this year, four in the Apopka area and one in Pine Hills. The county is on a state mosquito-borne illness alert.

Five people in Orange County have caught dengue fever from local mosquitoes this year. Four of the cases are in the Apopka area and one is in Pine Hills, the county said.

The Florida Department of Health had confirmed all five by Oct. 12, Orange County said in a release Friday. Pine Hills is about five miles west of downtown Orlando. Apopka is about 14 miles northwest. No case inside Orlando city limits has been announced.

How many cases, and where

The state’s weekly mosquito-borne illness report, the Florida Arbovirus Surveillance report for Oct. 4-10, counts the same five Orange County cases. Three of them began in August and two in September.

The report also shows:

  • 368 locally acquired dengue cases in Florida this year, from eight counties
  • 72 of those reported in the week of Oct. 4-10 alone
  • 310 of the 368 in Hillsborough County, around Tampa
  • seven more Orange County residents who caught dengue while traveling abroad

Orange County is one of seven Florida counties under a mosquito-borne illness alert, the report says. Ten others are under an advisory.

The Department of Health in Orange County first announced a local case on Sept. 2. It said it and Orange County Mosquito Control were widening surveillance and treating the affected communities.

Spraying from the air

Orange County Mosquito Control planned aerial spraying over parts of Apopka and Pine Hills starting at 7 p.m. Friday, Oct. 16. Saturday, Oct. 17, was the backup date if storms got in the way. The county has not yet said whether all of the planned spraying was done.

The Pine Hills treatment area covers residential neighborhoods:

  • around West Colonial Drive and North Pine Hills Road
  • near West Washington Street
  • Bel-Aire Woods and Orlo Vista

The county said people in those areas do not need to take extra steps to protect pets, livestock or gardens. It said the products are approved by the U.S. Environmental Protection Agency and the Florida Department of Agriculture and Consumer Services.

What it means for you

Dengue spreads through mosquito bites, and the county says the most effective control starts at home. In a September release, Orange County Mosquito Control and the Department of Health asked residents to:

  • check their yard at least once a week and empty or cover anything that holds water, including birdbaths, buckets, pet dishes, children’s pools, coolers, tarps, gutters, tires, recycling bins and toys
  • use an EPA-approved insect repellent, following the label
  • wear long, protective clothing when they can
  • keep windows and doors closed, and fix holes in screens

As little as a teaspoon of standing water left for more than a week can become a breeding site, the county said. Your recycling cart counts: see our trash and recycling guide for pickup days.
