New cases of the Zika virus, which is linked to birth defects, have been confirmed in Florida and Illinois, state officials said.
Two pregnant women in Illinois and three people in Florida were infected by the mosquito-borne virus while traveling outside of the country. Officials said they are monitoring both situations.
While Zika causes mild symptoms in most infected people, the virus can be particularly serious for pregnant women. Zika has been linked to a risk of the child being born with microcephaly, in which the babies have small heads and incomplete brain development. The Centers for Disease Control and Prevention has urged women traveling to areas where the virus is common, including South America, Latin America and the Caribbean, to take precautions.
