Overview
Zika virus disease is an acute infectious condition caused by the Zika virus, primarily transmitted through Aedes mosquito bites, sexual contact, blood transfusions, and from mother to fetus 2. It often presents with mild symptoms but can lead to severe complications including Guillain-Barré Syndrome (GBS) and congenital ZIKV syndrome 2.Diagnosis
Clinical Presentation: Body aches, joint pain, fatigue, malaise, fever, conjunctivitis, and maculopapular rash 2.
Laboratory Testing: Detection of Zika virus RNA in blood or other body fluids via RT-PCR; serological tests can be used but cross-reactivity with other flaviviruses is common 2.
Imaging: Not typically required for diagnosis but may be used to assess neurological complications 2.Management
Supportive Care: Most patients are managed conservatively with rest, hydration, and symptomatic treatment 2.
GBS Management: Intravenous immunoglobulins have been used, similar to conventional GBS treatment 2.
No Specific Antiviral Therapy: Currently, no antiviral therapy is available for ZIKV infection 2.Special Populations
Pregnancy: ZIKV infection during pregnancy can lead to congenital ZIKV syndrome; pregnant women should avoid areas with active transmission and use strict mosquito protection 2.
Neurological Complications: Special attention required for patients developing Guillain-Barré Syndrome or other neurological manifestations, with close monitoring and supportive care 2.Key Recommendations
Implement Mosquito Control Measures: Use of mosquito repellents, protective clothing, and environmental management to prevent mosquito breeding 2. (Evidence: Expert opinion)
Screen and Manage Pregnant Women: Pregnant women in affected areas should be screened for ZIKV infection and provided with appropriate counseling and care 2. (Evidence: Expert opinion)
Supportive Care for Symptomatic Patients: Focus on supportive care including hydration and pain management for symptomatic individuals 2. (Evidence: Moderate)References
