(Hospital San Pedro-Centro de Investigacion Biomedica de La Rioja, Logrono, Spain) for molecular analysis.
It shares many features with the other rickettsioses
, which were considered to be fading but are now resurging after the large epidemics that occurred prior to the introduction of antibiotics.
Thus, the lower fatality rates associated with RMSF may actually be due to the misdiagnosis of other rickettsioses
with lower fatality rates than RMSF.

It is likely that some, or possibly many, of the approximately 13,500 noncharacterized cases of spotted fever group rickettsioses
reported in the United States during 2008--2012 were caused by R.
2) The finding of an eschar is often indicative of rickettsial infection; however, not all rickettsioses
show eschars, and the absence of an eschar does not exclude rickettsial infection.
Ocular involvement in rickettsioses
is common, but is easily overlooked.
