A method of inhibiting the spread, transmission and incidence of disease, infection and asthma and rhinitis allergies, characteristic of hypersensitivity pneumonitis in structures employing forced or induced air ventilation, heating, humidification and air conditioning systems. Microorganisms contribute to the disease and aggravate the condition of allergies or initiate allergic response. In the method, the level of exposure of occupants of the structure to high levels of microorganisms is reduced by treating interior surfaces of the structure with an organosilicon quaternary ammonium compound. The threshold level of airborne microorganisms is lowered with the organosilicon quaternary ammonium compound in order to prevent reinfestation and the intrinsic antimicrobial activity of the treated surfaces is used to kill transient and resident microbes.
