Infection is acquired through breathing in aerosols (very fine droplets of water) which contain the bacteria. The most rapid proliferation occurs at 38☌. Optimal temperatures for Legionella growth are 25☌ - 50☌. These conditions allow the bacteria to multiply in large numbers. The temperature of water in these systems is kept between 28☌ and 45☌. Legionella may also be found in cooling towers associated with air-conditioning systems and industrial processes.
