Solutions A to Z Rocky Mountain Spotted Fever (RMSF) This acute, infectious disease is transmitted by ticks. The distinguishing feature is a characteristic rash. With early treatment, most children recover fully and develop permanent immunity. Untreated, however, the disease can be severe. Early medical intervention is thus essential. As the name implies, the disease causes a spotted rash and was first identified in the Rocky Mountain region. Now, more than half the annual cases occur in the Southeastern United States. Children from five to nine years of age are most frequently infected. Although the infected ticks are primarily encountered in the woods, they can also be found in suburban areas and occasionally urban areas. In almost half of reported cases, the tick bite was unnoticed. WHAT CAUSES ROCKY MOUNTAIN SPOTTED FEVER? RMSF is caused by Rickettsia rickettsii , a microorganism carried by rodents and other small mammals inhabiting infested areas. Ticks who feed on these animals acquire the microorganism and pass it along in their saliva. A child can pick up an infected tick directly when playing in a wooded, tick-infested area or indirectly from a pet who has picked one up.

LeRoy, DVM, PhD Class of 2004 (Otis) and Department of Pathology (Tarpley, Bain, Latimer, LeRoy), College of Veterinary Medicine, The University of Georgia, Athens, GA 30602-7388 Introduction Rocky Mountain Spotted Fever (RMSF) is an important zoonotic disease that may cause clinical signs in both dogs and humans. It is caused by the organism Rickettsia rickettsii , a small gram-negative obligate intracellular parasite from the family Rickettsiaceae. Transmission Hard-bodied ticks are the vectors of RMSF, and there are several species that have been known to be involved in its transmission. The most common vector in the eastern United States is Dermacentor variabilis (the American dog tick, Fig. 1) while Dermacentor andersoni (the wood tick, Fig. 2) is responsible for infections in the western part of the country . Amblyomma americanum and Rhipicephalus sanguineous also have been reported to carry the disease, although the vast majority of infections are due to the

Rocky Mountain spotted fever is most prevalent in the NW United States, although it may be encountered in other tick-infested regions. Symptoms include chills and high fever; a rose-colored skin rash that appears first on the wrists and ankles and spreads to the trunk, the spots turning deep red and running together; headache; and pains in the back, muscles, and joints.

Rocky Mountain Spotted Fever Fact Sheet What is Rocky Mountain Spotted Fever? Rocky Mountain Spotted Fever is a rickettsial disease caused by the organism, Rickettsia rickettsii . It is transmitted by the bite of an infected tick and results in a systemic, febrile illness. Who gets Rocky Mountain Spotted Fever? Anyone can become ill with Rocky Mountain Spotted Fever. Children and other people who are exposed more often to tick vectors are most frequently affected. How is Rocky Mountain Spotted Fever spread? Rocky Mountain Spotted Fever is spread through the bite of an infected tick. Several ticks are responsible for the spread of this disease, and these vary by geographic region. The dog tick, Dermacentor variabilis , is the most common reservoir for this organism in Nebraska. The organism becomes infectious after the tick has been attached to the skin for at least four to six hours. It can also be transmitted in the process of tick removal if the tick becomes crushed, allowing infectious material to escape. Rocky Mountain Spotted Fever is not directly transmitted from person to person.

It is spread by the bite of an infected tick. In Nebraska the American dog tick, which is mottled brown in color, is the most common carrier. The people most at risk are those who have exposure to tick-infested habitats, such as wooded and grassy areas. "With summer here, people will be outdoors more, doing activities like camping, fishing, hunting, and picnicking," said Dr. Richard Raymond, the state’s Chief Medical Officer, from the Nebraska Health and Human Services System. "That places them at risk of being bit by ticks. Having two cases so early this year, when we usually only have 3 to 6 cases per year, is worrisome." Symptoms usually appear within two weeks of the bite of an infected tick. They include the sudden onset of a moderate to high fever (which can last for two or three weeks), severe headache, fatigue, deep muscle pain, chills and rash. Antibiotics can treat the disease.

Rocky Mountain spotted fever Questions and Answers What is Rocky Mountain spotted fever? Rocky Mountain spotted fever (RMSF) is the most severe tick-borne rickettsial illness in the United States. This disease is caused by infection with the bacterial organism Rickettsia rickettsii How do people get Rocky Mountain spotted fever? The organism that causes Rocky Mountain spotted fever is transmitted by the bite of an infected tick. The American dog tick ( Dermacentor variabilis ) and Rocky Mountain wood tick ( Dermacentor andersoni ) are the primary vectors of Rocky Mountain spotted fever bacteria in the United States. What are the symptoms of Rocky Mountain spotted fever? Patients infected with R. rickettsii usually visit a physician in their first week of illness, following an incubation period of about 5-10 days after a tick bite. The early clinical presentation of Rocky Mountain spotted fever is often nonspecific and may resemble many other infectious and non-infectious diseases. Initial symptoms may include fever, nausea, vomiting, muscle pain, lack of appetite and severe headache. Later signs and symptoms include rash, abdominal pain, joint pain, and diarrhea. Three important components of the clinical presentation are fever, rash, and a previous tick bite, although one or more of these components may not be present when the patient is first seen for medical care. Rocky Mountain spotted fever can be a severe illness, and the majority of patients are hospitalized.

The disease is caused by Rickettsia rickettsii, a species of bacteria that is spread to humans by ixodid (hard) ticks. Rocky Mountain spotted fever is characterized by a sudden onset of symptoms and can be fatal if not treated. Between 1974 and 1982, an annual average of 112 cases and 3 deaths were reported in Virginia. In recent years, only about 30 cases and less than 1 death per year have been reported. Nearly all cases occur in spring and summer months. The Pathogen Rocky Mountain spotted fever is caused by Rickettsia rickettsii, a very small bacterium that must live inside the cells of its hosts. In humans, rickettsiae live and multiply primarily within cells that line small- to medium-sized blood vessels. Once inside the host the rickettsiae multiply, resulting in damage and death of these cells. This causes blood to leak through tiny holes in vessel walls into adjacent tissues. This process causes the rash that is traditionally associated with Rocky Mountain spotted fever and causes damage to organs and tissues.

Lyme Disease and Rocky Mountain Spotted Fever by Roy F. Dvorak Both of these diseases are caused by a tick, a member of a super-family (Ixodoidea) of wingless bloodsucking arachnids, including many species that transmit diseases. The bite of the Ixodes genus tick causes Lyme Disease. The tick attaches itself to the dog and begins to feed. The spirochetes (a spiral shaped bacteria that cause the disease) in the stomach of the tick move to the salivary glands of the tick and then into the host dog. If the tick is discovered within the first 24 hours after attachment, the chance of infection is very small. Appel and Jacobson, in their article CVT Update: Canine Lyme Disease , estimate that about 5% of the dogs in the geographical areas of the U.S. where Lyme Disease is endemic and are exposed to Lyme Disease, become affected, i.e., they develop the clinical signs of the disease. In other words, dogs have a small chance of acquiring Lyme Disease. A type of tetracycline antibiotic is used to kill the Lyme infection. "The proportion of dogs in endemic areas that develop clinical disease is relatively small." The canine citizenry responds fairly well to administered antibiotics. Arthritis is the main sign of a dog affected with Lyme Disease. In humans the signs are chronic arthritis and "severe central nervous system involvement" according to Appel and Jacobson.
