Four new mosquito-borne Zika cases in Miami-Dade County
Florida health officials on Monday reported four more mosquito-borne Zika infections in Miami-Dade County, including one case linked to the area of ongoing transmission in Miami Beach and two associated with the newly designated zone in Miami’s Little River neighborhood.
The fourth local infection reported Monday in Miami-Dade is under investigation to determine the area of exposure, according to the Florida Department of Health. In addition, state health officials reported three new travel-related infections, including one in Miami-Dade and two involving pregnant women. Florida does not identify the county of residence for pregnant women who acquire Zika.
In total, Florida has reported 1,031 Zika infections this year, with 179 local cases and 847 travel-related cases, including 108 pregnant women. An additional five cases have been labeled “undetermined” after state health officials failed to determine a local area of exposure.

Epidemiologists are conducting 10 investigations into local Zika infections, including seven cases in Miami-Dade, one in Palm Beach, and two where the area of exposure remains unknown because the persons visited Miami Beach and traveled abroad to a place where the virus is widespread.
A total of 168 people have contracted Zika from mosquitoes in Miami-Dade this year, according to state health officials, and an additional 238 residents acquired the virus while traveling abroad. The county remains the only one in Florida identified as having active spread of Zika by mosquitoes, including a one-square-mile zone in Miami’s Little River neighborhood and a 4.5-square-mile section of Miami Beach.
County officials also have reported finding mosquitoes that tested positive for Zika at seven different locations within the same Miami Beach zone.
