MRSA in Northeast Ohio

Four cases of infection from methicillin-resistant Staphylococcus aureus bacteria (MRSA) have emerged in the northeast Ohio area.

In Mentor, the school system reported three cases of MRSA. School officials said each case appears to be isolated.

In Bay Village, a Heinen's grocery store employee was confirmed to be infected. The Cuyahoga County Board of Health said it was not a public health concern.

I wonder what the upper limit is for isolated cases before MRSA can be classified as a public health concern. We've got at least four now. And, regarding all the "isolated" cases, I believe the authorities should determine where the patients came into contact with the bacteria before nonchalantly announcing that there is no public health concern.

Being part of the public, I can say I'm concerned.
