Disease Name

Rickettsia parkeri

Vector Information

Rickettsia parkeri is a bacterium that is similar to the bacterium that causes Rocky Mountain Spotted Fever. It is transmitted to people through the bite of an infected Gulf Coast tick. This disease is considered a mild form of Rickettsia infections and is treatable. This disease is also preventable if simple steps are taken to reduce exposure to ticks. 

This bacteria can be grouped under the heading Spotted Fever group Rickettsia (SFGR). This disease is similar to Rocky Mountain Spotted Fever. Symptoms from Rickettsia parkeri include fever, headache, eschar(s) at the site of the bite, and a variable rash. Symptom onset is normally within two weeks of a tick bite. R. parkeri is considered a mild form of SFGR. Diagnosis is made by a healthcare provider who will use clinical symptoms and patient history of possible tick bites. Treatment consists of administration of antibiotics. If SFGR is suspected at all, antibiotics should be given immediately and treatment should never be delayed pending the outcome of diagnostic tests. Treatment should be given for at least 3 days after symptoms subside. Standard treatment lasts 7 to 14 days.
