MINNEAPOLIS (WCCO) — Zika remains a global health emergency and continues to infect new countries, according to the World Health Organization.

The head of the Zika expert committee says so much about the mosquito-borne disease remains unknown, including the complications it causes. Currently 72 countries and territories are infected by Zika.

In the Midwest, Minnesota is among the top three states for people with Zika virus. We now have at least 40 cases here, according to the CDC’s latest count. Illinois and Michigan have slightly more.

All of the cases in Minnesota are associated with travel. They make up just one percent of the total cases in the United States.
