On July 3, 2020, Mid-Michigan News reported that the Michigan Department of Health and Human Services had failed to release data on COVID-19 mortality rates in patients with underlying medical conditions more than two months after promising to do so. On April 29, 2020, Michigan's Chief Medical Executive Dr. Joneigh Khaldun said she would review the data on COVID-19 deaths to determine how many of the people who died had underlying medical conditions. However, the numbers had still not be released as of July 3, 2020.
Public health experts have criticized the Department of Health and Human Services for failing to release the information. One doctor told reporters that "every state health department should be releasing" information about how people with pre-existing conditions have been affected by COVID-19, saying "the public needs to know what is the relative risk and who is at risk of this disease and who is at risk of dying of it."
