Rocky Mountain Spotted Fever (RMSF) is a serious tick-borne illness caused by the bacterium Rickettsia rickettsii. It is transmitted to humans through the bite of infected ticks, most commonly the American dog tick, Rocky Mountain wood tick, and brown dog tick. Early symptoms include fever, headache, muscle aches, and a distinctive rash that often begins on the wrists and ankles and spreads to other parts of the body.

Prompt treatment with doxycycline is essential to prevent severe complications such as organ failure or death. If you suspect RMSF, seek immediate medical attention. Learn more about symptoms, prevention, and treatment options here.
