Less than 2 percent of Wisconsin residents had antibodies to the virus that causes COVID-19 as of July, based on early results of a new study.
The study was conducted by the state Department of Health Services, the University of Wisconsin-Madison’s Survey of the Health of Wisconsin, or SHOW, and the Wisconsin Sate Laboratory of Hygiene. Preliminary results were released Tuesday.
The study tested 1,056 people and of those, 1.6% were positive for the antibodies, indicating that they had been previously infected, even if they didn’t have symptoms.
