We report a case of Legionella pneumophila pneumonia in a 7-day old neonate
. Because the hospital water, and particularly the pool water for water bir
thing, was contaminated by L. pneumophila serogroup 1, the newborn was infe
cted following prolonged delivery in contaminated water, perhaps by aspirat
ion. This is the first case of nosocomial Legionella pneumonia in neonate a
fter water birth.
