  1. Allergen avoidance in a day-care center.

    Article - En anglais

    The predominant sensitizing allergens in Swedish asthmatic children are furred pet animals.

    Poor ventilation and increased indoor humidity cause accumulation of pet allergens indoors.

    Indirect contacts with cats also increase pet allergen exposure.

    We investigated whether the concentration and the total amount of cat (Fel d I) and dog (Can f I) allergen in dust from various surfaces in a day-care center were influenced by extensive renovation, installation of a new ventilation system, ventilation of floors, and avoidance by families and personnel of direct and indirect contacts with pets.

    The cleaning routine in the day-care center was changed extensively after renovation.

    Old mattresses, pillowcases, curtains, sofas, and soft toys were removed, and new materials were purchased.

    Dust was collected from various surfaces before and after renovation from table and chair surfaces, floors, curtains, mattresses, pillows, cushion-like toys, and sofas on five occasions during a 12-month period.

    Fel d I and Can f I allergen levels were determined by sandwich ELISA.

    The reduction in the total amount of both Fel d I and Can f I/sampling area was more pronounced than the reduction in the concentration of allergen/g of dust.

    After renovation, the mean cat and dog allergen concentration was decreased by six and 10 times, respectively.

    After 1 year, the total amount of cat allergen was lower in all areas (from 24 ng to<1 ng/sampling area, P<0.05).
