Abstract
Background: Acute urticaria (AU) is characterized by the occurrence of spontaneous wheals, angioedema, or both for less than 6 weeks. Viral infection is considered to be one of the common causes of AU, however AU has never been reported in association with dengue infection.
Objective: To describe the first case of AU in dengue virus infection.
Methods: Case report
Results: A 17-year-old healthy male presented with first episode of AU which associated with confirmed dengue virus infection. He responded well with antihistamine treatment and without recurrence at 2-month follow up.
Conclusion: Patients with dengue virus infections can present with AU, possibly from viral-infected mast cell. Future research will have to clarify this association.
Key words: acute urticaria, dengue fever, mast cell, virus infection, wheal,
