While most (90%) people with RMSF have some type of rash during the course of illness, less than 50% of patients have a rash during the first 3 days of illness, when most people first seek medical...
Children represent less than 6% of spotted fever cases, but 22% of spotted fever fatalities.Children with RMSF frequently report experiencing nausea, vomiting, loss of appetite, and rash, but are less likely to report a headache than adults.Other frequently observed signs and symptoms in children with RMSF include abdominal pain, altered mental status, and edema involving the dorsum of the hands or around the eyes.Children < 10 years are five times more likely than adults to die from RMSF.Healthcare providers should also look at routine blood tests, such as a complete blood cell count and a chemistry panel when making the diagnosis. 1. General laboratory findings can include thrombocytopenia, hyponatremia, or elevated levels of hepatic transaminases although these tests may not appear abnormal in early stages of illness.
