A swimming pool or spa at a Kuta Beach (Bali) hotel are the most likely sources of the Legionellosis infection in two middle-aged Perth people, according to Western Australian health department epidemiologist, Dr Gary Dowse. He said the two holidayed independently at the unnamed hotel around the same time in August. More details.
Advice to travellers: The Legionella bacteria thrives in warm water, usually in air-conditioning systems of large buildings, but also hot water tanks, heated pools, spas etc. Transmitted by breathing in contaminated mist or vapor, Legionnaires disease is not contagious and presents a low risk to travellers.
