Its an aggressive fight in a rare case of plague in Central Oregon.  A Crook County man in his 50's continues to be in critical condition at St. Charles Bend today.  Crook County Health Department spokesperson Karen Yeargain says the Bubonic Plague actually has a higher survival rate than the form that this person has, which is in his bloodstream.   "The antibiotics start kicking in very quickly and then after that  it just depends on how the person is doing and they are given the utmost of medical care.  And at that point we watch and wait and hope."   Family members tell our news partner, News Channel 21 that they were told he only has a 30% survival rate.  The plague is extremely rare, with only 3 cases in Oregon since 1995.  One was in Crook County in '95 and two in Lake County.  All three people survived.  Health officials believe he was exposed to the plague through a sick cat that later died.
