Zika Outbreaks Confirmed in 2023

The Pan American Health Organization (PAHO) recently confirmed local transmission of Zika in countries and territories in the Region of the Americas. 

As of June 10, 2023, up to EW 21, 8,758 Zika cases were reported in the Region of the Americas.

The highest proportion of Zika cases were reported in Brazil (7,352), followed by Bolivia and Belize.

Furthermore, per Brazilian authorities, over 1,638 babies have been born with microcephaly-related health issues since 2014.

Previously, the U.S. CDC stated that because the mosquitoes that spread the Zika virus are found throughout Puerto Rico, people living on the island who have not already been infected are at risk for infection.

Puerto Rico's Weekly Arboviral Diseases Report #22 shows 26 probable Zika cases as of June 13, 2023.

As of June 15, 2023, the U.S. FDA has not approved a Zika vaccine candidate.
