What You Must Know About Rocky Mountain Spotted Fever
This tick-borne disease can be deadly, especially in children
Lyme disease, which infects an estimated 300,000 people in the U.S. every year, is the country’s most common tick-borne disease. But the deadliest tick-borne disease in the U.S. is actually Rocky Mountain spotted fever (RMSF).
According to a 2012 study in the American Journal of Tropical Medicine and Hygiene, between 1999 and 2007, RMSF killed about 14 people in the U.S. every year.
Rocky Mountain spotted fever was named for where it was discovered more than a century ago, and for the spotted rash that often occurs when it damages blood vessels under the skin.
But today, the disease (along with other tick-borne spotted fevers) occurs all across the U.S., not just in the Rocky Mountains. And even though a rash does occur in 90 percent of cases, it often doesn’t appear until after the onset of more vague, flu-like symptoms. In some cases, waiting to treat RMSF until a rash occurs can be fatal.
“Rocky Mountain spotted fever is a very rapidly progressing disease; it’s a really dangerous disease,” says Naomi Drexler, M.P.H., an epidemiologist with the Centers for Disease Control and Prevention’s Division of Vector-Borne Diseases.
Here are answers to several key questions about RMSF, what you need to know about this sometimes deadly disease, and how to protect yourself.

In my side pouches, you can find tent poles (right) and a SmartWater bottle (left). A sawyer squeeze is placed inline from the SmartWater bottle and attached to my Osprey mouthpiece to drink fro, as I walk.
The EWG sees picaridin as a reasonably good alternative to DEET—although it hasn’t been tested as long, it doesn’t have the same neurotoxicity concerns. They recommend a concentration of 20 percent for Lyme protection. Common brands include: OFF!, Cutter, Sawyer, Natrapel, Insect Guard.
Fill them up with tap water and it slowly passes through a filter system. Then the main reservoir below collects the filtered water.
