Most symptomatic rickettsial diseases cause moderate illness, but some Rocky Mountain and Brazilian spotted fevers, Mediterranean spotted fever, scrub typhus, and epidemic typhus may be fatal in 20%–60% of untreated cases.
Is there a vaccine for Rickettsia?
Currently, no vaccines are available to prevent RMSF in either people or dogs. Vaccine development against RMSF is complicated due to the limited understanding of the protective host response and the R. rickettsii antigens involved in stimulating protective immunity.
Is Rickettsia bacteria or virus?
