The importance of reducing risk in peanut allergy: Current and future therapies

The prevalence of peanut allergy has steadily increased during the past 10 years, especially in children. A 2009 to 2010 survey of more than 40,000 children (aged 0–17 years) in the United States found that peanut allergy was the most common food allergy, affecting 2% (1.5 million) of children nationwide.1 Data from a 2014 meta-analysis of 29 studies from multiple European countries using various reporting methods estimated the occurrence of peanut allergy to be 0.3% (by positive food challenge result) to 4.1% (by peanut specific IgE positivity) in children aged 2 to 5 years and 0.4% (by self-reporting) to 9.8% (by peanut specific IgE positivity) in children aged 6 to 17 years.
