Rift Valley fever
ICD-10 A98.3 is a billable code used to indicate a diagnosis of rift valley fever.
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.
Detailed travel history, symptomatology, and laboratory results.
Patients presenting with fever and recent travel to endemic areas.
Ensure comprehensive documentation of all symptoms and potential exposures.
Immediate assessment of symptoms, travel history, and potential exposure.
Patients with acute febrile illness and history of mosquito bites in endemic regions.
Rapid identification and reporting are crucial for outbreak management.
Used to confirm RVF diagnosis through serological testing.
Document the reason for testing and any relevant travel history.
Infectious disease specialists should ensure comprehensive documentation of all relevant clinical details.
Primary symptoms include fever, headache, myalgia, and in severe cases, hemorrhagic manifestations such as bleeding from the gums and gastrointestinal tract.
Diagnosis is based on clinical presentation, travel history to endemic areas, and laboratory confirmation through serological tests or PCR.
