The U.S. Centers for Disease Control and Prevention (CDC) previously issued travel, testing, and other guidance related to areas of active Zika virus transmission in Florida. Because local transmission of Zika virus continues to be reported in Miami-Dade County, CDC is strengthening travel recommendations for pregnant women to Miami-Dade County and also reinforcing recommendations for use of protective measures to prevent exposure to Zika. CDC is updating recommendations to emphasize testing for pregnant women with an epidemiologic link to Miami-Dade County. An epidemiologic link means that they lived in, traveled to, or had unprotected sex with someone who lived in or traveled to, the designated area. In addition, CDC has made specific recommendations for areas of identified active transmission.
The Florida Department of Health (FL DOH) has identified a new area where local, state, and CDC officials have determined that the intensity of Zika virus transmission presents a significant risk to pregnant women in a designated one-square-mile area located in Miami-Dade County (NW 79th St. to the north, NW 63rd St. to the south, NW 10th Ave. to the west and N. Miami Ave. to the east).
• Pregnant women should consider postponing travel to all areas of Miami-Dade County. Pregnant women should specifically avoid travel to the previously identified 4.5-square-mile area of Miami Beach and one-square-mile area in Little River located in Miami-Dade County (http//www.cdc.gov/zika/intheus/florida-update.html).
• Pregnant women who have an epidemiologic link to any area of Miami-Dade County after August 1, 2016 should be tested for Zika virus in accordance with CDC guidance (http://www.cdc.gov/mmwr/volumes/65/wr/mm6529e1.htm?s_cid=mm6529e1_e).
o Pregnant women with an epidemiologic link to the 4.5-square-mile area of Miami Beach with active Zika virus transmission, after July 14, 2016, should be tested for Zika virus.
Because the incubation period for Zika virus infection is up to two weeks and many people infected with Zika virus will not have symptoms or will only have mild symptoms, investigating cases may take several weeks. Data collected during the ongoing investigation indicate the period of time since August 1 represents the timeframe with the highest transmission in Miami-Dade County.
FL DOH and CDC continue to work together on this ongoing investigation to learn more about active Zika virus transmission in Miami-Dade County. CDC will update these recommendations as more information becomes available. Healthcare providers should visit CDC’s Zika website (http://www.cdc.gov/zika/) frequently for the most up-to-date recommendations.
