Tick/Mosquito-Borne Viruses

Florida Department of Health in Santa Rosa County


Arboviruses are a class of viruses spread to humans by arthropods such as mosquitoes and ticks. Some of the arboviruses that are transmitted by mosquitoes in Santa Rosa County include West Nile Virus (WNV), Eastern Equine Encephalitis (EEE), and Saint Louis Encephalitis (SLE). Tick-borne arboviruses that are transmitted in our county include Lyme Disease and Rocky Mountain Spotted Fever. Symptoms can vary from none to severe or even life threatening.

Common symptoms of arbovirus illness include: 

  • Fever
  • Headache
  • Tiredness
  • Dizziness
  • Confusion
  • Rash
  • Muscle weakness


To prevent mosquito-borne diseases, practice "DRAIN and COVER"

DRAIN standing water to stop mosquitoes from multiplying.

  • DISCARD: Old tires, drums, bottles, cans, pots, and pans, broken appliances and other items that are not being used.
  • EMPTY and CLEAN: Birdbaths and pets' water bowls at least once or twice a week.
  • PROTECT: Boats and vehicles from rain with tarps that do not accumulate water.
  • MAINTAIN: The water balance (pool chemistry) of swimming pools. Empty plastic swimming pools when not in use.

COVER your skin with clothing and use mosquito repellent.

  • CLOTHING: If you must be outside when mosquitoes are active (especially at dusk and dawn), cover up. Wear shoes, socks, long pants, and long sleeves.
  • REPELLENT: Apply mosquito repellent to bare skin and clothing.  Always use repellents according to the label.  Repellents with DEET, picaridin, oil of lemon, and IR3535 are effective. Use mosquito netting to protect children younger than two months.

COVER doors and windows with screens to keep mosquitoes out.
