Summary
Orchard pollinosis, a type of hay fever caused by orchard pollen, affects 0.37% of students surveyed in China. This highlights the need for increased attention to this significant allergic condition.
Area of Science:
- Allergy and Immunology
- Epidemiology
- Environmental Health
Context:
- Orchard pollinosis, a seasonal allergic rhinitis, is prevalent in regions with significant fruit cultivation.
- Understanding the epidemiology of orchard pollen allergy is crucial for public health management in affected areas.
Purpose:
- To determine the prevalence of orchard pollinosis among students in China.
- To assess the clinical significance of orchard pollen allergy.
Summary:
- An epidemiological survey conducted from 1995 to 1998 involving 1,660 primary/middle school students and 2,167 university students utilized questionnaires, nasal inspections, and scratch tests.
- A subsequent clinical investigation in 1998 included 30 allergic rhinitis patients, employing scratch tests and nasal mucosa examinations.
- Results indicated a 6.7% positive rate for orchard pollen scratch tests and a 0.37% prevalence of orchard pollinosis. Clinical allergen testing revealed hypersensitivity to orchard pollen in 16.7% of patients.
Impact:
- Orchard pollinosis represents a notable form of pollinosis requiring significant public health attention.
- Findings underscore the importance of identifying and managing orchard pollen allergies to mitigate their impact on student populations.
