Study Details

Study Description

Brief Summary

The investigators surveyed the prevalence of animal allergy and sensitization to animal allergen among participants in international symposium of Korean association for laboratory science (laboratory animal researchers) and companion animal exhibition (pet owner and pet-related industry workers).

Condition or Disease	Intervention/Treatment	Phase
Allergic Rhinitis Allergic Conjunctivitis Urticaria Asthma	Other: Animal allergy Other: Non-animal allergy

Detailed Description

The investigators enrolled participants in international symposium of Korean association for laboratory science (laboratory animal researchers) and pet animal exhibition (pet owner and pet-related industry workers) after informed consents. Subjects were asked to response to questionnaires regarding their age, gender, comorbid allergic disease, family history of allergy, pet or laboratory animal, exposure time, allergic symptoms during exposure to animals. Subjects underwent skin prick test with animal allergens and other inhalant allergens.
