Zika fever is a mild febrile illness caused by a mosquito-borne virus similar to those that cause dengue and West Nile virus infection. 

Zika virus has been linked to serious birth defects, including microcephaly, when contracted by expectant mothers during pregnancy. Microcephaly is a birth defect where a baby’s head is smaller than expected when compared to babies of the same sex and age. Babies with microcephaly often have smaller brains that might not have developed properly.

Zika virus has been identified in several countries in Central and South America, Mexico, and the Caribbean since 2015. Outbreaks have previously been reported in Africa, Southeast Asia, and the Pacific Islands. Local transmission has been reported in Puerto Rico and Florida. Cases of Zika fever have been reported in travelers returning to the United States.

Information on Limited Local Transmissions

There are no areas of ongoing, active transmission of Zika by mosquitoes in Florida. All previous Zika zones in the following areas of Miami-Dade County have been lifted after 45 days with no evidence of active transmission and no additional people infected. It is not uncommon, however, for there to be isolated incidents of locally acquired Zika.

The department continues to closely monitor the status of Zika virus in Florida and take action to keep Floridians, especially pregnant women, safe. If the department identifies any areas of concern, the public and the media will be notified.

  • Wynwood (zone lifted Sept. 19, 2016)
  • north part of Miami Beach (zone lifted Nov. 22, 2016)
  • Little River (zone lifted Dec. 2, 2016)
  • South Miami Beach (zone lifted Dec. 9, 2016)

The department advises residents and visitors to Miami-Dade County to remain vigilant about mosquito bite protection by draining all sources of standing water to keep mosquitoes from breeding and by wearing bug repellent.

Information on Active Investigations

When a local case of Zika virus is confirmed through laboratory testing, the department conducts a thorough investigation around the case to determine if additional people are infected. The department interviews and tests close contacts and community members around the case. Knowing if additional people are infected helps the department determine if there is a zone where mosquitoes are transmitting the virus. Not every case results in a designation of active transmission in an area. In some instances, a case of Zika is an isolated incident with no additional people infected. More information on the department’s testing and investigation process.

Zika fever is acquired through the bite of an infected mosquito, including the same mosquitoes that can transmit dengue and chikungunya. Perinatal and sexual transmission have also been reported.

CDC - Effective condom use to prevent sexual transmission

Only about 1 in 5 people infected with Zika virus are symptomatic. Zika fever is a mild illness. Severe disease requiring hospitalization is uncommon. Signs and symptoms of Zika fever may include: acute onset of low-grade fever, rash, joint pain, conjunctivitis (reddening of eye), body aches, headache, eye pain, and vomiting. Treatment is symptomatic since there is no specific treatment against the virus. Illness typically resolves within a week.

The Ministry of Health of Brazil has reported an increase in the numbers of newborns with microcephaly in areas experiencing Zika virus outbreaks. Further studies are being conducted to investigate this concern. There are many causes of microcephaly in babies, including genetic abnormalities, environmental factors, and some infections acquired during pregnancy.

Mosquito Bite Protection for Overseas Travelers / Spanish

Travelers to a tropical or sub-tropical area (Africa, Asia, Caribbean, Mexico, Central and South America), can protect themselves from Zika and other mosquito-borne diseases by following these prevention suggestions:

  • Use insect repellant with any of the following active ingredients
    • DEET (up to 30%)
    • Picaridin
    • Oil of lemon eucalyptus
    • Para-menthane diol
    • IR3535
    • Always follow product label instructions and make sure repellent is age-appropriate.
    • It is safe for pregnant or nursing women to use EPA-approved repellants if applied according to package label instructions.
    • Apply repellent on bare skin or clothing, not under clothing.
  • Cover skin with long-sleeved shirts and long pants
    • Apply a permethrin repellent directly to clothing or purchase pre-treated clothing. Follow the manufacturer’s directions and do not apply directly to the skin.
  •  Keep mosquitoes out of hotel rooms
    • Choose a hotel or lodging with air conditioning or screens on windows and doors.
    • Sleep under a mosquito bed net when outside or in a room that is not screened.
