Rocky Mountain spotted fever (RMSF) is an infection caused by a type of bacteria carried by ticks. Despite its name, cases of RMSF have been reported throughout the entire United States, not just in one area.
Most cases occur in children.
Peak time to catch it is between April to September.
You can help prevent it by helping your child avoid tick bites, including proper dress and insect repellent.
Treatment usually includes antibiotics.
Complications are rare, but could be serious.
Is Rocky Mountain spotted fever common?
It affects about 250 to 1,200 people a year in the United States and usually occurs from April until September, but it can occur anytime during the year where weather is warm. The mid-Atlantic and southeastern states are most affected. According to the Centers for Disease Control and Prevention, the people most at risk include:
Children 15 and under, particularly children between 5 and 9 years old
Children who are frequently around dogs
Children who live near wooded areas or areas with high grass
Symptoms & Causes
What are the symptoms of Rocky Mountain spotted fever?
While symptoms may vary child-to-child, the most common include:
A non-itchy rash that usually starts on the hands, arms, feet, and legs, and occurs seven to 10 days after the bite
You can catch RMSF by being bitten by an infected tick. It's not spread from one person to another.
Can you prevent Rocky Mountain spotted fever?
To prevent your child from getting RMSF to begin with, be sure to walk on cleared paths and pavement through wooded areas and fields when possible. Also, have your child follow these steps when spending time outdoors:
Dress properly
Light-colored clothing
Long-sleeved shirts tucked into pants
Socks and closed-toe shoes
Long pants with legs tucked into socks
Look for ticks
Any parts of the body that bends (behind the knees, between fingers and toes, underarms, and groin)
Belly button, in and behind the ears, neck, hairline, and top of the head
Anywhere else where clothing presses on the skin (such as the band on pants or underwear)
Hair (run a fine-toothed comb through your child's hair)
Shower after all outdoor activities
It may take up to four to six hours for ticks to attach firmly to skin; showering may help remove loose ticks
Use insect repellents
DEET is a tick repellent, but doesn't kill the tick and is not 100 percent effective.
Use a children's insect repellent
Check with your child's doctor if your child is younger than 1
Treat clothing with a product that contains permethrin, which is known to kill ticks on contact. Do not use permethrin on the skin.
Diagnosis & Treatments
How do we diagnose Rocky Mountain spotted fever?
Your doctor will ask about any previous tick bites and look at the symptoms, especially the rash. Skin samples and lab tests are usually done to rule out other conditions.
How do we treat Rocky Mountain spotted fever?
If there is a concern about RMSF antibiotics may be started right away along with other therapies to treat the symptoms your child may be experiencing. Complications are rare, but could include death.
