Preventing Legionellosis covers the biology of Legionella and presents a comprehensive review of best practices for legionellosis prevention from around the world. Recent outbreaks, climbing incidence rates and pending lawsuits have raised public awareness about legionellosis, a serious, preventable form of pneumonia that can be contracted from water systems in buildings. Legionellosis has harmed millions of people worldwide and causes annual monetary losses in the billions.
