Florida Zika zone triples, cases increase to 93

Sept. 22, 2016 -- The zone of active transmission of Zika virus in Miami Beach has tripled to encompass two-thirds of the seaside city. Gov. Rick Scott announced on that the Florida Department of Health expanded its area of Zika investigation from 20 blocks to a 4.5 square-mile zone covering all of South and Middle Beach.

The department recently identified five non-travel related Zika cases - two males and three females - in the expanded area. This brings the total number of non-travel related cases associated with this expanded area to 35. The total number of non-travel related cases in Florida is 93, which includes people who live outside of Florida, but contracted Zika in the state.

The first four U.S. cases of non-travel acquired Zika were reported by the Florida Department of Health on July 29 in the Wynwood arts district of North Miami. On Sept. 19, CDC relaxed its travel recommendations for this area west of Miami Beach. Instead of urging pregnant women to avoid all travel to the Wynwood district, CDC now suggests pregnant women and their partners "consider postponing nonessential travel" to the area. The updated guidance and advice for people living in or traveling to effected areas in Florida are available on the CDC website.

All Zika cases in Iowa currently are travel-related. Weekly reports about these cases and other updates are available on the IDPH website.

Iowa health care providers wanting to test for Zika virus should contact Iowa Department of Public Health's Center for Acute Disease Epidemiology (CADE) at 800-362-2736. CADE staff will consult with the provider to determine if the case meets CDC testing criteria, and coordinate the collection and delivery of appropriate specimens to the State Hygienic Laboratory.
