Clinical Report: Severe European subtype tick-borne encephalitis in a child
Overview
This report details a case of severe tick-borne encephalitis (TBE) in a fully vaccinated 9-year-old child, highlighting the unusual occurrence of a fatal outcome despite immunocompetence and vaccination. The TBE virus was identified as the European subtype through genomic analysis.
Background
Tick-borne encephalitis (TBE) is a viral infection transmitted by ticks, with increasing incidence in Europe, particularly the European subtype. Traditionally viewed as a mild illness in children, recent evidence suggests that severe cases can occur, necessitating awareness among healthcare providers regarding potential complications even in vaccinated individuals.
Data Highlights
No numerical data or trial data presented in the article.
Key Findings
A 9-year-old previously healthy child developed severe TBE despite being fully vaccinated.
The clinical presentation included a biphasic course with initial headache, nausea, and vomiting, leading to lethargy and neurological symptoms.
Serum tests indicated elevated white blood cell count and CRP levels, but blood cultures were negative.
CT scans initially assessed as normal later revealed significant findings upon reassessment.
This case challenges the perception that children are at low risk for severe TBE, even when vaccinated.
Clinical Implications
Healthcare providers should remain vigilant for TBE in pediatric patients, even those who are fully vaccinated, particularly in endemic areas. This case underscores the importance of considering TBE in differential diagnoses for children presenting with neurological symptoms.
Conclusion
The occurrence of severe TBE in a vaccinated child highlights the need for ongoing surveillance and awareness of the disease's potential severity in pediatric populations.
