Detroit Mayor Duggan’s executive assistant, Vicki Kovari, says this is an all-out effort to battle COVID-19 in the city.

“We’re hoping to get started by the end of April,” she told WWJ Newsradio 950’s Sandra McNeill. “And the first stage of this canvassing we will knock on every residential door in the city of Detroit; approximately 220,000 doors.”

The effort comes after Mayor Duggan on Monday warned of skyrocketing COVID rates in the city.

The number of people in the hospital, he said, has tripled in two weeks; while the city’s vaccination rate is just 21% — well below the statewide average.
