Lifeguard Lung: Endemic Granulomatous Pneumonitis in an Indoor Swimming Pool

PDF: Lifeguard Lung

This study found that lifeguards in the subject swimming pool developed granulomatous lung disease associated with endotoxin-containing respirable bioaerosols from water spray features, which ventilation system improvements did not prevent.

Attack rates for the outbreaks were between 27% and 65%.  Chloramines and other disinfectant by-products (DBPs) caused permanent lung scarring to these lifeguards involved with the study.  The study found a direct correlation between the pool air quality and their conditions.
