The latest tally of active confirmed cases of COVID-19 in Wisconsin is 46, including a growing number of infections that don't have a known source, state health officials said Monday.

Health officials now believe the state is among those with community spread, meaning people have the virus who did not recently travel or come in contact with a previously confirmed case.

As of Monday, there were 13 in Milwaukee County, 11 in Fond du Lac County, 10 cases in Dane County, three each in Sheboygan, Waukesha and Winnebago counties, and one each in Outagamie, Pierce, Racine and Wood counties. Dane County's total includes a patient who has recovered.

State Department of Health Services chief medical officer Ryan Westergaard said local health departments are still conducting interviews with people to determine their travel history and contact with others who have the virus, but confirmed cases with no such history are signaling "likely" spread in the community.

"How widespread? We don't know," Westergaard said Monday, adding that community transmission is not in all parts of the state but certainly could reach that point if the trajectory of the virus continues as projected.

California, Washington and New York were the first states to report community transmission of the virus. But as the number of confirmed cases across the U.S. continues to grow, other states have found evidence of it, including Michigan, Massachusetts and Minnesota.

After community spread was reported in the Massachusetts, Gov. Charlie Baker said it was time to get "a lot more aggressive" about limiting places that people gather. He moved to ban gatherings of more than 25 people, limit restaurants to takeout and delivery, and close schools.

Wisconsin Gov. Tony Evers had already taken such action by the time state health officials said they believed there was evidence of community spread.

Last Friday, he closed all public and private schools throughout the state until at least April 6. Monday, he echoed new guidance from the Centers for Disease Control and banned gatherings of more than 50 people.

The new CDC guidance also means bars, restaurants and businesses throughout the state will need to limit their capacity, Evers said Monday.

Negative tests surpassed 500 Monday, according to the state DHS Services website.

Deaths from COVID-19 surpassed 70 in the U.S. and 7,000 worldwide on Monday, according to the Johns Hopkins University global case dashboard.

If you suspect you may have the virus, and your symptoms — which include fever and lower respiratory problems — are not life-threatening, it is recommended you call before coming in to a clinic to be tested.
