Via the Centre for Health Protection: Update on cases of Legionnaires' disease. Excerpt:
The Centre for Health Protection (CHP) of the Department of Health today (June 27) reported the latest number of cases of Legionnaires' disease (LD) in Hong Kong, and stressed the importance of using and maintaining properly designed man-made water systems, and that susceptible groups should strictly observe relevant precautions.
From June 19 to 25, two community-acquired LD cases were reported. They are:
1. A man aged 66 with underlying illnesses who lives in Sau King House, Sau Mau Ping Estate; and
2. A man aged 69 with good past health who lives in Kam Hon House, Choi Hung Estate, Wong Tai Sin.
"Epidemiological investigations are ongoing to identify potential sources of infection, high-risk exposure and clusters, if any," a spokesman for the CHP said.
As of June 25, a total of 31 LD cases, including 30 community-acquired cases and one institutional death case, had been reported in 2016. In 2015 and 2014, there were 66 and 41 cases respectively.
Legionellae are found in various environmental settings and grow well in warm water (20 to 45 degrees Celsius). They can be found in aqueous environments such as water tanks, hot and cold water systems, cooling towers, whirlpools and spas, water fountains and home apparatus that support breathing. People may get infected when they breathe in contaminated droplets (aerosols) and mist generated by artificial water systems. They may also get the infection when handling garden soil, compost and potting mixes.
