3 pregnant women in Illinois confirmed with Zika virus

Posted: Updated:

The Zika virus continues to pop up in the Midwest.

There are 46 confirmed cases of Zika across Illinois, and three pregnant women are among those cases, according to the Illinois Department of Public Health.

"We have 8 women in the Zika Virus Pregnancy Registry because at the time of testing they were positive for a flavivirus – CDC was not able to confirm in 5 of those cases whether it was Zika virus or Dengue fever," according to Divya Mohan Little, Public Information Officer at the Illinois Department of Health.

Zika primarily spreads through bites from tropical mosquitoes. In most people, the virus causes only mild illness, but infection during pregnancy can lead to severe brain-related birth defects for the fetus.

The type mosquito that carries the virus will not be able to survive harsh winters in Illinois, but public health officials say they will continue to trap and test mosquitos statewide as a precaution.
