Code Description

ICD-10 A98.3 is a billable code used to indicate a diagnosis of rift valley fever.

Key Diagnostic Point:

Rift Valley fever (RVF) is an arthropod-borne viral disease caused by the Rift Valley fever virus (RVFV), primarily transmitted by mosquitoes. The disease is endemic in parts of Africa and the Arabian Peninsula, with outbreaks often linked to heavy rainfall and flooding, which increase mosquito populations. Clinically, RVF can present with a range of symptoms, from mild flu-like signs such as fever, headache, and myalgia to more severe manifestations, including hemorrhagic fever, encephalitis, and ocular disease. Hemorrhagic manifestations may include bleeding from the gums, nose, and gastrointestinal tract, which can lead to significant morbidity and mortality. Travel history is crucial in diagnosing RVF, as it is often associated with exposure to infected livestock or mosquito bites in endemic areas. Laboratory confirmation is typically achieved through serological tests or PCR. Given the potential for outbreaks and the severe nature of the disease, RVF is a significant public health concern, necessitating accurate diagnosis and reporting for effective management and control.
