ST. PAUL — State health officials confirmed a case of the rare mosquito-borne Zika virus on Wednesday in a woman who had visited Latin America, insisting there’s not a risk of it spreading in Minnesota but stressing the rare disease’s potential danger to pregnant women.

The Anoka County woman, who is in her 60s, had recently returned from Honduras, which is in the heart of an outbreak that started last year. She was not hospitalized and is expected to make a full recovery, Minnesota’s Department of Health and the Centers for Disease Control and Prevention said.

Zika usually causes a mild illness, but the tropical disease is also suspected in an unusual birth defect in which newborns’ heads are smaller than normal and the brain doesn’t develop properly. In Brazil, health officials have noticed a sharp spike in cases of those birth defects amid the Zika virus outbreak; the connection is still being investigated.

The virus is thought to only spread via mosquitoes, and not from person to person. State health officials said 80 percent of people infected with the virus will experience no symptoms.

“Zika virus is not a health threat for people in Minnesota, but it is a reminder that anyone traveling to a different part of the world should be mindful of the health issues present in that region,” Health Commissioner Ed Ehlinger said in a statement. “Since some regions where Zika is circulating are popular destinations for Minnesota travelers in the winter, we expected we might see cases of Zika in the state.”

It’s only the second confirmed case in Minnesota. The first was detected in 2014 in a man returning from a trip to French Polynesia.
