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.
Rocky Mountain spotted fever is found throughout the country, but it's most common in the eastern U.S. Signs and symptoms of this illness can be flu-like at first. During the first week, a red rash may appear on the wrists and ankles and eventually spread up the arms and legs to the chest. A mild case of the infection that's treated promptly with antibiotics typically causes few problems.
