The Zika virus is a mosquito-born flavivirus. Outbreaks are occurring in many countries.

In Iowa, the general public is not at risk of contracting this virus because the mosquitoes that transmit Zika are not established in Iowa; however, Iowans traveling to areas where there is ongoing Zika virus transmission should take care to protect themselves from mosquito bites.Zika: Travel Notice

Zika: PregnancyThere is risk for pregnant women or those women trying to become pregnant as the Zika virus may cause birth defects.

Because there is no vaccine or preventive therapy for Zika, the CDC recommends that pregnant women should consider postponing travel to areas where Zika transmission in ongoing.


The Zika virus is transmitted to people primarily through mosquito bites. These types of mosquitoes are called the Aedes species and are common around the world. 

These mosquitoes typically lay eggs in and near standing water in things like buckets, bowls, animal dishes, flower pots and vases.  They are aggressive daytime biters, prefer to bite people, and live indoors and outdoors near people.

Mosquitoes become infected when they feed on a person already infected with the virus. Infected mosquitoes can then spread the virus to other people through bites.
