title: Rat-bite fever presenting with rash and septic arthritis.
abstract: Rat-bite fever is an uncommon disease known for its endemicity to occur worldwide. Although most patients tend to develop mild symptoms with improvement from conventional antibiotics, it can progress with severe complications with a mortality rate as high as 13% without proper treatment. The authors report a complicated case of rat bite-fever involving a 61-year old woman who presented with fever petechial rash, and septic arthritis following a rat bite. Initially, multiple antibiotics were administered but were not effective. As a consequence, invasive procedures such as arthrotomy and joint debridement were done and prolonged antibiotic was administered until clinical resolution. Since many cases do not have a history of rat bite and may present with fever, rashes, and arthritis it is essential to distinguish it from other diseases. Here, the authors will provide details on the etiology, clinical manifestations, diagnosis, and management to aid prompt detection and treatment of the disease.
