Epidemiology of Rubella Virus in a Fragile and Conflict-affected Setting – A Retrospective Analysis of 11 Years Case-based Data in South Sudan
To assess the burden of rubella infection in South Sudan to advocate for the introduction of the rubella-containing vaccine into the national immunization program, targeting policymakers and health authorities.
Key Findings:
17,987 suspected measles cases reported with 4,944 serum samples collected, indicating a significant surveillance effort.
2,083 (42.1%) tested positive for measles IgM antibodies, highlighting the ongoing measles burden.
678 (23.7%) of 2,861 samples negative for measles tested positive for rubella IgM antibodies, suggesting a substantial rubella presence.
Rubella positivity rates increased from 1.6% in 2014 to 34.4% in 2020, indicating a rising public health concern.
Higher likelihood of rubella infection in children aged 1-9 years and in urban areas, emphasizing the need for targeted vaccination strategies.
Interpretation:
The study highlights a significant burden of rubella infection in South Sudan, particularly among children, indicating a critical need for vaccination strategies to protect vulnerable populations.
Limitations:
Limited epidemiological data on rubella in South Sudan may restrict the comprehensiveness of the findings.
Potential biases in surveillance data due to conflict-affected settings could impact the reliability of the results.
Conclusion:
Findings strongly support the introduction of the rubella vaccine into South Sudan's national immunization program to mitigate the public health threat posed by rubella.
