An evaluation of total immunoglobulin E (IgE) and dengue serostatus in 168
subjects from San Andres Island, Colombia, revealed altered levels of IgE i
n 89% of the population. IgE levels were higher in patients with a history
of dengue or with a current secondary or current primary infection than in
subjects with no exposure (P = 0.01). Dengue infection accounted for 23% of
the variation in IgE levels.
