Lots of viral illnes: Many self healing viral illnesses will present with significant fever, rapid breathing and particularly a speckled rash .A normal WBC with higher % lymphs points to a viral process. Breathing increases 5 breaths/min for every degree of fever as a normal reflection of increased metabolism. As long as the kid wets diapers every 6hr & plays some, you can wait it out.If it spooks you get a recheck.

RMSF?: I think i answered your question previously regarding rmsf. The results of the CBC with normal WBC and high lymphocyte count represents more of a viral infection with a rash. Further monitoring of the rash seems prudent. If the rash progresses, does not blanch and looks like blood clots, a repeat CBC may be necessary to look for decreasing platelet count found in rmsf.
