Aedes Aegypti Mosquito

Zika fever is a mild febrile illness caused by a mosquito-borne virus similar to those that cause dengue and West Nile virus infection. It 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 also been reported in Puerto Rico. Cases of Zika fever have been reported in travelers returning to the United States.

Information on Limited Local Transmissions

Florida has confirmed local transmissions of Zika virus are occurring in two small areas in Miami-Dade County. Area One is a small, less than one-square mile area in Miami-Dade County, just north of downtown. The department has found no evidence of transmission of Zika around nearly the entire perimeter of the area in Wynwood. This does not change CDC’s guidance for pregnant women or the Wynwood area. See Map 1 below.

Area Two is a less-than 1.5 square mile area in Miami Beach within the boundaries of 8th and 28th streets. Map 2 below indicates the impacted area in Miami Beach.

Florida’s small case cluster is not considered widespread transmission. If the department identifies additional areas of concern, we will notify the media and the public immediately.

CLOSED INVESTIGATIONS

  • The department has closed out the investigations into the first cases in Miami-Dade and Broward County (two cases). On Aug. 23, the department had enough information to close two of the ongoing investigations in Miami-Dade County, both were determined to be single cases with no additional transmission or linkage to areas of active transmission.


Data as of Aug. 29, 2016 - 6:03pm EST

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.

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.

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.
