Rocky Mountain Spotted Fever (RMSF) is a serious tick-borne disease caused by the bacterium Rickettsia rickettsii. Symptoms can include a distinct rash, fever, headache, and muscle pain and may develop several days after a tick bite. Early detection and antibiotic treatment are crucial.

Symptoms of Rocky Mountain Spotted Fever

• A rash that often begins as small red spots on the wrists, ankles, palms, or soles and spreads toward the trunk.

• Fever, chills, headache, muscle aches, fatigue, nausea, vomiting, diarrhea, or loss of appetite.

Causes

RMSF is transmitted through the bite of an infected tick, including the American dog tick, Rocky Mountain wood tick, and brown dog tick.

How to Prevent Rocky Mountain Spotted Fever

• Avoid brushy or wooded areas when possible and stay on clear trails.

• Use EPA-approved tick repellents and wear long sleeves and pants.

• Perform thorough tick checks after outdoor activities.

• Remove attached ticks promptly with fine-tipped tweezers and clean the bite area.

Treatment for Rocky Mountain Spotted Fever

Prompt antibiotic treatment is the primary treatment for suspected RMSF. Seek medical attention quickly if symptoms appear after a possible tick bite, since early treatment substantially reduces the risk of serious complications.
