Rocky Mountain Spotted Fever (RMSF) is a tick borne disease caused by the organism, Rickettsia rickettsii. Typically, the progress of the disease is a sudden onset of high fever, deep muscle pain, severe headache and chills. A rash usually appears on the extremities within 5 days then soon spreads to palms and soles and then rapidly to the trunk.

Fatalities can be seen in greater than 20% of untreated cases. Death is uncommon with prompt recognition and treatment. Still approximately 3-5% of cases seen in the U.S. are fatal. The absence or delayed appearance of the typical rash or the failure to recognize it, especially in dark-skinned people cause a delay in diagnosis and increased fatalities.
Early stages of RMSF can be confused with erlichiosis, meningococcal meningitis and enteroviral infection.

The organism is maintained in nature in ticks. It can be transmitted to dogs and other mammals, but most times these cases cause little illness. People usually get infected from an infected tick bite. The tickrequires from several hours to 24 hours of attachment and feeding to become infectious to people. So prompt removal of the tick can prevent infection. It is not transmitted person to person.
RMSF can be diagnosed in the laboratory using serological techniques, PCR or culture; however because of the necessity of prompt treatment, diagnosis is based on symptoms. There is no vaccine available for RMSF. It can be treated with tetracyclines either orally or intravenously.

One thought on “Mexico: Rickettsiosis cases and deaths up in Baja California this year”
Tick infections deserve a serious upgrade in attention. People are getting hit with 2 or 3 infections at a time with one bite, going to the doctor and being told their symptoms are imagined, or getting shuffled door to door and getting slapped with false, generic diagnosis like chronic fatigue, fibromyalgia, anxiety, etc. The tests are not accurate. Treatments are often ineffective and the extreme lack of funding and continued denial of this huge problem has created a terrible situation.
