Zika virus is spread to people primarily through the bite of an infected mosquito, but can also be transmitted through sexual interaction or from mother to child. The mosquitoes that can become infected with and spread Zika virus live in many parts of the world, including parts of the United States.
WHAT IS NEW?
- Aedes albopictus, one species of mosquito that is capable of transmitting Zika, has been identified in Wisconsin during July 2017. There is no evidence of Zika-infected mosquitoes in Wisconsin.
- There is still no evidence of local transmission of Zika in Wisconsin. Wisconsin residents at risk for Zika virus infection are people who have traveled or had sexual contact with someone who traveled to locations with active Zika virus transmission.
- The Florida Department of Health and the Texas Department of State Health Services have identified certain areas in Florida and Texas where Zika is being spread by local mosquitoes. For more detailed information on local transmission and travel advisories, see The Centers for Disease Control’s (CDC) Zika Virus Update for Florida and Texas.
