If you guessed Rocky Mountain Spotted Fever on the Guess that Summer Rash, then you got it right! So, let’s talk about Rocky Mountain Spotted Fever (RMSF):
It’s a serious illness caused by a bacteria called Rickettsia rickettsii, and it’s spread through tick bites—mainly from the American dog tick (see picture below). RMSF is actually the most common tick-borne illness in the U.S., especially in the Southeast and South Central states.
At first, the symptoms can be really vague and might look just like a virus: fever, headache, and rash. That rash shows up in about 90% of cases, but it usually doesn’t appear right away. When it does, it often starts as flat spots on the wrists and ankles, then spreads inward. Later on, it can turn into a more serious rash that shows up on the palms and soles, which is a big clue something more is going on.
The tricky part is that these symptoms can look like other illnesses—things like sepsis, Kawasaki disease, or meningococcemia—so it’s important to get your child checked out quickly if they have these signs, especially after a known tick bite or being outside in tick-prone areas. Doctors usually start treatment right away if they suspect RMSF, even before any test results come back, because the illness can get worse fast. The good news? Antibiotics work really well when started early.

So how do we prevent tick bites and RMSF?
Here are some simple steps to protect your child:
• Use tick repellent. Products with DEET, picaridin, or clothing treated with permethrin work best. These are all considered safe for kids 2 months and older when used the right way.
• Dress smart. Long pants tucked into socks and shirts tucked into pants can help keep ticks off the skin.
• Be careful with spray repellents. Don’t spray directly on your child’s face. Instead, spray your hands and gently apply it to their face—just avoid eyes and mouth.
• Skip the “natural” stuff. Things like citronella and botanical oils haven’t been proven to work as well on ticks.
• Check for ticks often. Especially after outdoor play, hiking, or time in grassy or wooded areas. If you find a tick, remove it right away.
As always, if you have any questions, send me a message or talk to your child’s pediatrician about your their needs!
