New assessments of mosquito populations and test results this month by Florida public health officials, as part of a community survey in the Miami neighborhood where several Zika infections were recently confirmed, have found persistent mosquito populations and additional Zika infections in the same area, according to a news update from the Centers for Disease Control and Prevention.
This information suggests that there is a risk of continued active transmission of Zika virus in that area. As a result, CDC and Florida are issuing travel, testing and other recommendations for people who traveled to or lived in the Florida-designated areas on or after June 15, 2016, the earliest known date that one of the people could have been infected with Zika.
- Pregnant women not travel to the identified area.
- Pregnant women and their partners living in this area should consistently follow steps to prevent mosquito bites and sexual transmission of Zika.
- Pregnant women who traveled to this area on or after June 15, 2016, should talk with their healthcare provider and should be tested for Zika.
- Pregnant women without symptoms of Zika who live in or frequently travel to this area should be tested for Zika virus infection in the first and second trimesters of pregnancy.
- Male and female sexual partners of pregnant women who live in or who have traveled to this area should consistently and correctly use condoms or other barriers against infection during sex or abstain from sex for the duration of the pregnancy.
- All pregnant women in the United States who live in or travel to an area with active Zika virus transmission, or who have sex with a partner who lives in or traveled to an area with active Zika virus transmission without using condoms or other barrier methods to prevent infection should be assessed for possible Zika virus exposure during each prenatal care visit and tested according to CDC guidance.
- Women and men who traveled to this area wait at least 8 weeks before trying for a pregnancy; men with symptoms of Zika wait at least 6 months before trying for a pregnancy.
- Women and men who live in or frequently travel to this area who do not have signs or symptoms consistent with Zika virus disease and are considering pregnancy should consider the risks associated with Zika virus infection, and may wish to consult their healthcare provider to help inform their decisions about timing of pregnancy.
- Anyone with possible exposure to Zika virus and symptoms of Zika should be tested for Zika.
“We work closely with Florida to gather and analyze new information every day. With the new information that there are active mosquitoes still in the area and additional Zika infections, we conclude that pregnant women should avoid this area – and make every effort to prevent mosquito bites if they live or work there,” said CDC Director Tom Frieden, MD, MPH. “We apply the same criteria within and outside of the United States, and are working closely with the State of Florida and Miami health departments to provide preventive services, including mosquito control.”
