Zika threat growing in Ohio

Expanding the map has escalated concerns among medical professionals in Ohio and other states previously thought to be a low risk of Zika, which the CDC U.S. Centers for Disease Control and Prevention recently confirmed causes microcephaly during pregnancy — a condition in which babies are born with very small heads and brain damage.

Zika’s symptoms, which include fever, rash and joint pain, are usually mild in adults, who often show no signs of the virus, and rarely get sick enough to go to the hospital.

A Dayton Daily News investigation examines the plans Ohio health officials have to fight the spread of Zika by mosquitoes.
