Update November 22, 2013: There has been a media report
about the possiblity of cats being infected with this virus. We have
contacted the Michigan authorities with a request for more information.
Canine circovirus infections have been documented in dogs with vomiting and diarrhea. The distribution of the virus in the U.S. is not yet known, but dogs infected with circovirus have been reported in California and circovirus may be associated with recent illness and death of dogs in Ohio.
A: As of October 3, the Michigan Department of Agriculture and Rural Development has been investigating illnesses similar to those observed in Ohio. The investigation will take time, and at this time they are not confirming that circovirus is involved.
