TOPEKA, Kan. (KSNW) – The Kansas Department of Health now says the state has four cases of Zika virus. There is one new case in south-central Kansas and northeast Kansas.

State health officials said both cases are travel-associated.  Both traveled to a country with “local Zika virus transmission.”

The Zika virus is spread mainly by a tropical mosquito and causes a mild illness in most people. But infection during pregnancy can cause fetal deaths and birth defects.

State health officials said in March that an adult from southwest Kansas was the state’s first confirmed case of the Zika virus. That person also had traveled to a country with “local Zika virus transmission.”
