Rocky Mountain spotted fever (RMSF) has been a nationally notifiable condition since the 1920s. As of January 1, 2010, cases of RMSF are reported under a new category called Spotted Fever Rickettsiosis (SFR). This category captures cases of RMSF, R. parkeri rickettsiosis, Pacific Coast tick fever, and rickettsialpox.

Ticks are parasitic arthropods that feed on the blood of vertebrates, particularly mammals (including humans) but also birds, reptiles and amphibians. Many species of ticks can transmit pathogens between animals and to humans, including various parasitic worms, viruses, and bacteria. The most important of these in Pennsylvania are the bacteria that...
Lyme Disease
Lyme Disease or Lyme borreliosis is an infection caused by the bacterial spirochete Borrelia burgdorferi, which is transmitted by ixodid ticks. Humans, dogs, and horses seem to be the most susceptible to the infection. It is a multisystem illness characterized initially by erythema migrans (bullseye rash) and a series of common nonspecific complaints and symptoms including headache, fever, sore throat, and nausea. Left untreated, it may progress to late phase symptoms including debilitating r...
Rocky Mountain Spotted Fever
RMSF is caused by the bacteria Rickettsia rickettsii. The disease was first recognized in the United States during the 1890s, but until the 1930s it was reported only in the Rocky Mountains. By 1963, over 90 percent of all cases were reported east of the Rockies. Rickettsia rickettsia is vectored by American dog ticks and lone star ticks in the eastern US, while it is vectored in the western US by Rocky Mountain wood ticks (Dermacentor andersoni). Symptoms of RMSF include a fever and often a...
Tularemia
Tularemia, which is also called rabbit fever, is caused by the bacterium Francisella tularensis. The bacterium can be vectored by lone star ticks, American dog ticks, Rocky Mountain wood ticks, rabbit ticks (Haemaphysalis leporispalustris), and deer flies, as well as exposure to rabbit blood (e.g., butchering a rabbit without gloves and other protection or via aerosolized blood after a rabbit is struck by a lawnmower). The number of cases in the United States has dropped considerably in the l...
The best way to avoid tick bites is to stay out of wooded or brushy areas. However, this option is not always realistic. Repellents such as DEET (N,N-Diethyl-meta-toluamide) offer considerable protection if applied to clothing and exposed skin. Another protective option is the application of Permanone™, an effective acaricide that contains the synt...
Lyme disease and other tick-borne diseases also affect livestock and companion animals, in particular dogs and horses. For information on prevention and control in animals, please see the Penn State fact sheets on Protecting Companion Animals Against Ticks in Pennsylvania and Protecting Livestock Against Ticks in Pennsylvania.
To help find your path, the Pennsylvania Historical and Museum Commission (PHMC) has blazed several special-interest trails leading to some of Pennsylvania's most historic sites. We invite you to explore one site at a time, travel an entire trail, or create your own road trip to Pennsylvania's past.
