Overview
Rift Valley fever (RVF) is a viral zoonosis caused by the RVF virus, primarily affecting livestock but also humans, manifesting with febrile, encephalitic, and hemorrhagic syndromes, and can include severe ocular complications 1.Diagnosis
Serological diagnosis (IgM/IgG antibodies) is crucial 1.
Ocular manifestations include bilateral macular, paramacular, and extramacular retinal lesions, often with hemorrhage, edema, vasculitis, retinitis, and vascular occlusion, identifiable via color photography and fluorescein angiography 1.Management
Supportive care is essential for managing systemic manifestations 1.
Specific antiviral treatments are not detailed in the provided abstracts; focus on symptom management and monitoring 1.
For ocular complications, close ophthalmological follow-up is necessary, though specific therapeutic interventions are not specified in the abstracts 1.Special Populations
No specific data provided regarding pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1.Key Recommendations
Conduct serological testing (IgM/IgG antibodies) for definitive diagnosis of RVF 1.
Implement comprehensive supportive care measures for systemic RVF symptoms 1.
Provide close ophthalmological monitoring for patients with ocular manifestations due to potential permanent visual impairment 1 (Evidence: Moderate).References
