The Michigan Department of Community Health says there have been 67 meningitis cases as of Friday.
There also have been 131 epidural abscesses, one stroke and 14 peripheral joint infections linked to contaminated steroids produced by a Massachusetts pharmacy used in injections for neck or back pain.
The department reported 197 infections on Nov. 30.
The number of deaths in Michigan has remained unchanged in the past week at 13. That includes three state residents who contracted infections in Indiana.
A majority of the Michigan cases are being treated at St. Joseph Mercy Hospital just east of Ann Arbor.
