The CDC says, between May 2014 and February 2015 there have been 243 cases in 32 states and Puerto Rico. Three cases have been reported so far in Michigan, according to the Michigan Department of Community Health.

The problem is that the bacteria is resistant to the antibiotic Cipro which is what’s used to usually treat the infection. One can get Shigella from an infected person or contaminated food or water.
