Monroe County Health officials say they have confirmed the first case of the Zika virus in their county.
Officials say this case, like the other previously confirmed cases of Zika in Michigan , is associated with travel to areas where the virus is already present.
Officials have not commented on the identity of the patient, or where they may have become infected.
Zika causes mild symptoms , most commonly fever, rash, joint pain and conjunctivitis. It can also trigger muscle pain and headache. The symptoms can last for several days to a week.
However, pregnant woman or who who could become pregnant are most at risk from contracting the virus, because it has been traced to microcephaly and other fetal brain defects.
Zika is transmitted through mosquito bites. However, mosquitos in Michigan are not known to be carriers of the virus. Zika can also be transmitted through sexual contact with a person who is already infected with the virus.
