What Kind of Ticks Carry the Disease?

In the United States, these include the American Dog tick, (Dermacentor variabilis),Rocky Mountain Wood Tick, (Dermacentor andersoni), and Brown Dog Tick, (Rhipicephalus sanguineus)

Are There Any Cures?

Rocky Mountain Spotted Fever is a fatal if not treated within 5 days of noticed symptoms.

Doxycycline is the first line treatment for adults and children of any age. This is most effective if started before the fifth day of symptoms. Besides Deoxycyline is the primary treatment and is the most effective. Scientists and doctors are still searching for a more aggressive and effective treatment.
