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.
Conclusions:
Patients with dengue virus infections can present with AU, possibly from viral-infected mast cell. Future research will have to clarify this association.
