In what month will Wisconsin's rolling 7-day positivity rate reach 4.5% or below?
As of October 16th, 2020, the 7-day rolling positivity rate was 10.4% (7-day percent positive by test, total tests by day: https://www.dhs.wisconsin.gov/covid-19/data.htm). The WHO's guidance for governments has stated any positivity rate above 5.0% should equate to more strict limitations on business activity and social movement.
We will use the state's Department of Public Health as our source to judge this question. Decimals will be rounded to the nearest tenth place. For example, if the 7-day rolling positivity percentage (7-day percent positive by test, total tests by day) on a given day is 4.54%, this question would resolve as having occurred, since 4.54% rounded = 4.5%.
