To the Editor.—  In the article by Breiman et al,1 microbial air sampling was conducted to help establish the source of an outbreak of legionnaires' disease linked to shower use. This complements another article in which similar environmental sampling techniques identified an evaporative condenser as the source of Legionella infection.2 We have used similar methods to demonstrate the association of three cases of legionnaires' disease and the use of a whirlpool-spa.Three cases of legionnaires' disease were reported to the New York State Department of Health in September 1989. All three patients were members of a 20-man golf team that had stayed at a Vermont resort hotel. The resort health club had two whirlpool-spas, only one of which was functional and was used by all three patients 3 days prior to the onset of illness.
