Passive dispersion of latex aeroallergen in a healthcare facility.

Background: Prompted by worsening asthma in a dental assistant with latex allergy and occupational asthma while under personal latex precautions, we confirmed continuing latex aeroallergen exposure.

Objectives: To determine the source of latex aeroallergen and ascertain the effects of site-wide substitution of nonpowdered low allergen latex glove in a health care site.

Methods: Using a volumetric sampler, baseline latex aeroallergen levels were measured in rooms where she worked and nearby rooms, as well as shared X-ray, laboratory, and waiting rooms.
