The number of people who get<unk>  is 4–100 per 100,000 persons per year, with a lifetime risk of 0.05–2%. About 30% of people get more than one attack. Exercise-induced<unk>  affects about 1 in 2000 young people. Rates appear to be increasing: the numbers in the 1980s were approximately 20 per 100,000 per year, while in the 1990s it was 50 per 100,000 per year. The increase appears to be primarily for food-induced<unk> . The risk is greatest in young people and females.<unk>  leads to as many as 500–1,000 deaths per year (2.7 per million) in the United States, 20 deaths per year in the United Kingdom (0.33 per million), and 15 deaths per year in Australia (0.64 per million). Another estimate from the United States puts the death rate at 0.7 per million. Mortality rates have decreased between the 1970s and 2000s. In Australia, death from food-induced<unk>  occur primarily in women while deaths due to insect bites primarily occur in males. Death from<unk>  is most commonly triggered by medications.
