You can catch RMSF by being bitten by an infected tick. It's not spread from one person to another, not just in one area.
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 is frequently around dogs
- children who lives near wooded areas or areas with high grass

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
- decreased appetite
- sore throat
- stomach ache
- nausea or vomiting
- body aches
- sensitivity to light
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 right
- 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 bend (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.
