Rocky Mountain Spotted Fever
Rocky Mountain spotted fever (RMSF) is spread to people through the bite of an infected tick. Symptoms of RMSF typically begin 3–12 days after the bite and often include sudden onset of headache, fever, stomach and muscle pain. Rash may develop after several days of illness. When not treated early, RMSF can get worse very quickly, and can be fatal, even in previously healthy people. Because early symptoms are often vague and can resemble so many other diseases, it can be difficult to diagnose.
- Doxycycline is the treatment of choice for RMSF in adults and children of all ages. It is most effective if started before the 5th day of symptoms.
- Children <10 years of age are five times as likely to die from RMSF than adults.
- RMSF can occur during any month, but the majority of cases have an illness onset during the summer months.
- North Carolina, Oklahoma, Arkansas, Tennessee and Missouri account for over 6 in 10 cases of RMSF in the United States.
- Use Environmental Protection Agency (EPA)-registered insect repellents containing DEET, picaridin, IR3535, oil of lemon eucalyptus (OLE), para-menthane-diol (PMD), or 2-undecanone on exposed skin.
- Treat clothing and gear with products containing 0.5% permethrin.
- Bathe or shower as soon as possible after coming indoors to wash off and more easily find ticks that are crawling on you.
- Check yourself, your kids, and your pets for ticks daily, especially after they spend time outdoors in areas where ticks may be found.
- Remove attached ticks as soon as possible. The preferred method of removal is to grasp the tick close to the skin with tweezers or fine-tipped forceps and gently pull upward with constant pressure.
