Incidence and prevalence are terms commonly used in describing disease epidemiology. Incidence is newly diagnosed cases, which can be expressed as new cases per year per million people. Prevalence is the number of cases alive, expressible as existing cases per million people during a period of time. Worldwide, the prevalence of<unk>  is increasing because<unk>  consumption is increasing, and among adults<unk>  is the most common anaphylaxis-eliciting food. Reviews cite self-reported<unk>  in range of 0.5 to 2.5 percent in the general population. Prevalence is higher in coastal southeast Asian countries, where<unk>  consumption is more common. Self-reported allergy prevalence is always higher than food-challenge confirmed allergy, which one review put at 0% to 0.9% (the higher value in southeast Asia).
