Some states have released data, but it's still largely unknown how widely COVID-19 has hit communities of color.

In Michigan and Illinois, African Americans account for about a third of coronavirus cases and about 40 percent of deaths, even though that demographic only makes up 15 and 14 percent, respectively, of the states' total populations.
