while the specificity of a physician 's diagnosis of the rickettsial diseases appears to be high ( i.e. , few cases of other diseases are misdiagnosed as either spotted fever or murine typhus ) , the sensitivity of the physician 's diagnosis may be lower ( i.e. , many cases of these diseases presenting as fevers of unknown origin are not diagnosed as rickettsial disease ) .
