Officials say there are at least 20 confirmed cases of meningitis in Michigan, including two deaths.
The number of cases reported Sunday was up from eight reported Saturday. The Michigan Department of Community Health says it's unable to release details about the deaths until after the weekend.
The meningitis outbreak has been linked to a steroid produced by a specialty pharmacy in Massachusetts. The steroid has been recalled, and officials have been scrambling to notify anyone who may have been injected with it.
At least four places in Michigan received shipments of the medication: Michigan Neurosurgical Institute in Grand Blanc; Michigan Pain Specialists in Brighton; Neuromuscular & Rehabilitation in Traverse City; and Southeast Michigan Surgical Hospital in Warren.
The Centers for Disease Control and Prevention reports 91 cases nationally.
