Four recent cases in Central Oregon of meningococcal, but health experts assure us they are not connected. Yesterday in Deschutes County officials confirmed a 2nd case.  And in Crook County there were also two cases recently.  Health officials say in this latest case its an entirely different strain; so that means there is no connection to the previous three cases. "Now we've had 3 different strains in the four cases and so much is not known with meningococcal cases. Why is one a Sertype Y and one a Serotype B and the others were C's there is just so much we don't know at this time." Tom Kuhn with the Deschutes County Health Department says in this recent case the person is a female in her 30's and she's doing well. Kuhn says its unusual to have four cases around the same time,  but again this isn't considered an outbreak because they are not connected.
