What is Rocky Mountain spotted fever? Rocky Mountain spotted fever (RMSF) is a tick-borne disease caused by a rickettsia (a microbe that differs somewhat from bacteria and virus). Fewer than 50 cases are reported annually in New York State.
The usual incubation time between tick bite and symptom onset is 5-10 days. Only about half of patients recall a preceding tick bite. Initial symptoms of Rocky Mountain spotted fever are usually non-specific, consisting of fever, severe headache, myalgias, nausea and loss of appetite. Many patients will present to physicians before the hallmark rash develops, which complicates diagnosis and increases the diseaseâs potential deadliness.
