19 new cases of coronavirus in Wisconsin linked to election activities: State health officials

State health officials in Wisconsin said Tuesday that 19 people who have either voted in-person or worked at a polling site on election day have so far tested positive for COVID-19 after April 9, two days after the spring election, underscoring the risks of forging ahead with an in-person voting during the height of the widespread and deadly public health crisis.

But a department spokesperson told ABC News that several of those people "reported other possible exposures as well." Officials are hesitant to link the new cases of the coronavirus directly to the election.

"Since we only have data on positive cases (without a comparison group of people who were not tested or tested negative), there is no way to know with certainty if any exposures at the polls that are reported are in fact attributable to COVID-19 illness," the spokesperson said.
