ST. PAUL, Minn. (AP) — State health officials say they've confirmed a case of a rare mosquito-borne virus, but say it's not a risk to spread in Minnesota.

Minnesota's Department of Health and the Centers for Disease Control and Prevention announced the Zika virus case Wednesday. It was found in a woman in her 60s living in Anoka county who returned from a trip to Honduras.

The rare tropical disease is spreading in Latin America and the Caribbean. It usually causes a mild illness but is suspected in an unusual birth defect and other health issues. The CDC is warning pregnant women against traveling to several countries in Central and South America.

State health commissioner Ed Ehlinger says the virus isn't a threat in Minnesota. The state says most infected patients experience no symptoms.
