Allergies in the U.S. 2025
As we move through 2025, allergies continue to be one of the most widespread and costly health challenges in the United States, affecting tens of millions of people across all ages, races, and socioeconomic backgrounds. From mild seasonal allergies to life-threatening food or drug reactions, allergic conditions impose a substantial burden on individuals, families, and the healthcare system. Over 30% of U.S. adults and more than a quarter of children report living with at least one allergic condition, impacting their daily activities, school or work performance, and overall well-being. With rising prevalence rates and emerging disparities, the urgency to improve allergy awareness, diagnosis, and management has never been greater.
Allergic conditions are not only increasing in number but also in complexity. Women, Black Americans, and children are disproportionately affected by many types of allergies, including eczema, food allergies, and seasonal triggers. The unpredictable and sometimes fatal nature of severe allergic reactions—such as anaphylaxis from insect stings or food exposure—underscores the need for broader public education, access to epinephrine auto-injectors, and better allergy care infrastructure. This report presents the latest U.S. allergy data to highlight the patterns, disparities, and clinical realities of allergic diseases in 2025, offering a comprehensive overview to guide policy, care, and prevention strategies.

Eczema, also known as atopic dermatitis, represents a chronic inflammatory skin condition that significantly impacts quality of life for both children and adults. The higher prevalence in children (10.8%) compared to adults (7.3%) suggests that many individuals may see improvement in their condition as they age, though the substantial adult prevalence indicates that eczema often persists into adulthood or may develop later in life.
The demographic patterns for eczema reveal concerning disparities, particularly affecting Black children at 14.2%, significantly higher than other racial groups. This elevated prevalence among Black children may reflect genetic predisposition, environmental factors, or differences in access to preventive care and treatment. The consistent pattern of women being more affected than men across all age groups (8.9% versus 5.7% in adults) suggests hormonal influences on the development and persistence of eczema.
Healthcare Utilization for Allergies in the U.S. 2019
| Type of Healthcare Visit | Annual Volume |
|---|---|
| Physician office visits for allergic rhinitis | 4.1 million |
| Emergency department visits for eczema/contact dermatitis | 229,000 |
| Physician office visits with hay fever diagnosis (2010) | 11.1 million |
| Worldwide drug reaction hospitalizations | Up to 20% of patients |
| Fatal reactions from drug allergies worldwide | Up to 20% of anaphylaxis deaths |
The healthcare utilization data for allergic conditions reveals the substantial burden these diseases place on the American healthcare system. With 4.1 million physician office visits annually for allergic rhinitis alone, allergies represent a significant source of healthcare demand and associated costs. The 229,000 emergency department visits for eczema and contact dermatitis underscore the severity of symptoms that some patients experience and the need for acute medical intervention.
The comparison between 4.1 million visits for allergic rhinitis in 2019 and 11.1 million visits with hay fever diagnosis in 2010 suggests either changes in diagnostic coding practices, treatment patterns, or possibly shifts in how patients access care for seasonal allergies. The worldwide statistics on drug reactions provide sobering context, with up to 20% of hospitalized patients experiencing adverse drug reactions and drugs being responsible for up to 20% of fatal anaphylaxis cases, highlighting the critical importance of proper allergy assessment and medication management.
Severe Allergic Reactions in the U.S. 2025
| Severe Reaction Type | Key Statistics |
|---|---|
| Children with history of severe food reactions | 38.7% |
| Fatal insect reactions without prior history | Up to 50% |
| Adults reporting penicillin allergy | 10% |
| Adults actually allergic to penicillin | Less than 1% |
| Worldwide anaphylaxis deaths from drugs | Up to 20% |
| Lifetime prevalence of urticaria | Above 20% |
The statistics on severe allergic reactions reveal the life-threatening potential of allergic conditions and the importance of emergency preparedness. The finding that 38.7% of food-allergic children have a history of severe reactions emphasizes the critical need for emergency action plans, epinephrine auto-injectors, and comprehensive allergy management in schools and childcare settings. This high percentage of severe reactions among food-allergic children underscores why food allergies are considered one of the most serious chronic conditions affecting children.
Perhaps most alarming is the statistic that up to 50% of fatal insect sting reactions occur in individuals with no documented history of previous systemic reactions. This unpredictability of severe allergic reactions means that anyone can potentially experience a life-threatening reaction to an insect sting, regardless of their previous experiences. The dramatic discrepancy between the 10% of adults who report penicillin allergies and the less than 1% who are actually allergic highlights the importance of proper allergy testing and the potential consequences of incorrectly assumed drug allergies on treatment options.
