Rocky Mountain spotted fever (RMSF) is a disease caused by the Gram-negative coccobacillus Rickettsia ricketsii which has been on the rise since the last decade in the USA. The symptoms are common to the many viral diseases, and the classic triad of fever, rash and headache is not always present
We reviewed 48 cases of Rocky Mountain spotted fever seen between 1943 and 1986. The data provided a view of the diverse presentations and manifestations of this disease. Exposure to a rural environment or to dogs was the rule, and over two-thirds of patients specifically remembered tick exposure.
Brazilian spotted fever is an acute febrile infectious disease caused by Rickettsia rickettsii, transmitted by tick bite. As this disease is rare and has high mortality rates in Brazil, the clinical aspects and epidemiological data may help the diagnosis. We report a case of Brazilian spotted fever
In a 28-year-old male American tourist who presented in the hospital with fever, cold shivers, headache, nausea, myalgia and arthralgia, Rocky Mountain spotted fever was suspected, partly because he came from an endemic region (the state of Georgia). The patient was treated with doxycycline, 100 mg
Late appearance of a skin rash in Rocky Mountain spotted fever is associated with a high mortality. Our patient's rash appeared 14 days after the onset of illness, during his recovery. In endemic areas one must rely on clinical clues other than rash to raise the suspicion of Rocky Mountain spotted
Rocky Mountain spotted fever (RMSF) is an unusual but important dermatological condition to identify without hesitation. The classic triad of headache, fever, and a rash that begins on the extremities and travels proximally to involve the trunk is found in a majority of patients. The cutaneous
BACKGROUND
Rocky Mountain spotted fever (RMSF) is an acute, serious tick borne illness caused by Rickettsia rickettsi. Frequently, RMSF is manifested by headache, a typical rash and fever but atypical disease is common, making diagnosis difficult. Inflammatory arthritis as a manifestation is rare.
Initial symptoms of Rocky Mountain spotted fever (RMSF), a tick-borne illness caused by Rickettsia rickettsii, are nonspecific and include headache, gastrointestinal disturbances, malaise, and myalgias, followed by fever and rash. The classic triad of fever, rash, and history of tick exposure is
We describe the first molecular confirmation of Rickettsia rickettsii, the cause of Rocky Mountain spotted fever (RMSF), from a tick vector, Amblyomma cajennense, and from a cluster of fatal spotted fever cases in Argentina. Questing A. cajennense ticks were collected at or near sites of presumed or
Rocky mountain spotted fever (RMSF) is a fulminant tick-borne infection by Rickettsia rickettsii. The classical diagnostic triad is fever, headache and rash in a patient with a recent tick bite. With prompt, appropriate antimicrobial therapy, patient outcomes are excellent. However, RMSF is often
Rocky Mountain spotted fever is caused by the tick-borne bacterium Rickettsia rickettsii. Symptoms range from moderate illness to severe illness, including cardiovascular compromise, coma and death. The disease is prevalent in most of the USA, especially during warmer months. The trademark
The reported average annual incidence of Rocky Mountain spotted fever (RMSF) in Kentucky is less than 5 per million population, although seroprevalence studies suggest that exposure to Rickettsia riskettsii, the causative agent, is relatively common among children. The experience with RMSF at Kosair
A dog was examined because of petechiation, an inability to stand, pale mucous membranes, a possible seizure, and thrombocytopenia. Tick-borne illness was suspected, but despite treatment, the dog died. Eight days later, a second dog owned by the same individual also died. The dog was not examined
BACKGROUND
Rocky Mountain spotted fever is a highly lethal infectious disease, particularly if specific treatment with doxycycline is given belatedly.
OBJECTIVE
To describe the clinical profile of fatal Rocky Mountain spotted fever cases in hospitalized patients in the state of Sonora,
BACKGROUND
Rocky Mountain spotted fever (RMSF) is an increasingly important cause of preventable mortality in children in Sonora, Mexico. Although early treatment with tetracycline has shown to prevent fatal outcome, the disease remains a life-threatening condition, particularly for children. This
