== Microbiology ==

* Disease caused by ''Rickettsia akari'', an intracellular Gram-negative bacterium
* Unlike most rickettsiae, it has a plasmid

== Epidemiology ==

* Transmitted by the house mouse mite (''Liponyssoides sanguineus'')
** Rodents are the reservoir
* Most cases are in New York, but it is found worldwide
* Most likely rickettsiosis to be found in Ontario
* Homelessness and IV drug use are risk factors

== Clinical Presentation ==

* Incubation period of 7 to 14 days
* Present with fever, vesicular rash, and eschar
** Headache also common
* The eschar is painless, and appears as a papule about a week after innoculation, followed by vesicle that dries and leaves a brown or black eschar
* The rash is vesicular, but may be papulovesicular or any other type of rash
** Lesions leaves black crust and heal without scarring
** Spares palms and soles
** Resolves in two to three weeks
* May find leukocytosis

== Diagnosis ==

* Detection of a four-fold rise in convalescent titres by complement fixation or indirect fluorescent antibodies

== Management ==

* Usually self-limited, resolving in 7 to 10 days, though antibiotics help
* Doxycycline 100 mg po bid for 2 to 5 days and 48 h after fever resolves
