biostudies-literatureUnknown6Chen J<h4>Background</h4>Shrimp allergy (SA) represents a significant public health concern, yet its overall prevalence remains unclear.<h4>Method</h4>A systematic search of PubMed, Web of Science, and Embase through September 30, 2024 identified 40 studies that reported SA prevalence using self-reported symptoms, physician diagnosis, skin prick tests, specific IgE, or food challenge tests.<h4>Results</h4>The pooled prevalence was estimated at 1.90% for self-reported symptomatic SA and 1.94% for self-reported physician-diagnosed SA, while testing via skin prick or specific IgE yielded a prevalence of 2.76%. Notably, symptomatic testing showed a lower prevalence of 0.43%, and food challenge tests confirmed a prevalence of 0.50%.
