Assessing Seroprevalence of Zika Virus in a Dengue-Endemic Community: Utilizing Blood Donor Samples and Multiplex Serology for Arbovirus Surveillance in the Dutch Caribbean
To determine Zika virus (ZIKV) seroprevalence during and after outbreaks in Aruba and Curaacao using blood donor samples, highlighting the significance of understanding ZIKV dynamics in endemic regions.
Key Findings:
ZIKV seroprevalence in Curaacao was 25%, significantly higher than Aruba's 8%, indicating a need for targeted public health interventions.
Flavivirus IgG antibody titers increased with age (P < .05), suggesting age-related exposure patterns.
Methodology effectively disentangled ZIKV exposure from other flaviviruses, providing a clearer understanding of seroprevalence.
Interpretation:
The study highlights the importance of age in interpreting serology data and provides insights into complex antibody patterns of flaviviruses over time, with implications for public health strategies.
Limitations:
Cross-reactivity of antibodies complicates serological analysis, potentially affecting the accuracy of seroprevalence estimates.
Potential underreporting of ZIKV cases due to asymptomatic infections may skew the understanding of outbreak magnitude.
Conclusion:
The study demonstrates the utility of blood donor programs for monitoring flavivirus outbreaks and emphasizes the need for accurate serological methods in endemic regions, advocating for ongoing surveillance.
