Rat-bite fever (Streptobacillus moniliformis infection)
ICD-10 A25.1 is a billable code used to indicate a diagnosis of rat-bite fever (streptobacillus moniliformis infection).
Rat-bite fever is a zoonotic infection caused by the bacterium Streptobacillus moniliformis, primarily transmitted through bites or scratches from infected rats or contact with their secretions. The disease can manifest in two forms: the acute form, characterized by fever, chills, and rash, and the chronic form, which may present with recurrent episodes of fever and arthritis. Symptoms typically appear 3 to 10 days after exposure and can include headache, myalgia, and nausea. Diagnosis is often made through clinical evaluation and serological testing. Treatment usually involves antibiotics, with penicillin being the most effective. Public health measures focus on rodent control and education to prevent transmission, especially in areas with high rodent populations. Awareness of this disease is crucial for healthcare providers, particularly in urban settings where rat infestations are common.
