INDIANAPOLIS (AP) — Indiana health officials say the state has its first case of Zika virus.

The Indiana State Department of Health announced Tuesday the person with the virus is “a non-pregnant resident” who recently traveled to Haiti.

There have been about 50 cases of the mosquito-spread virus reported in the United States, most in travelers returning from affected countries.

Many people infected do not get sick. For those who do, it is usually a mild illness with symptoms including fever, rash, joint pain and red eyes.

The virus is primarily spread through bites from a specific mosquito. Health officials are investigating whether there is a link between Zika infections in pregnant women and a rare birth defect called microcephaly, in which babies are born with abnormally small heads.

Ohio has also reported a case in Cleveland woman, who also recently returned from Haiti. Zika has been reported in 12 states and the District of Columbia.
