Chp reports increase in legionnaires' disease cases, emphasizes importance of proper water system maintenance and precautions for high-risk groups
The Centre for Health Protection (CHP) of the Department of Health today (July 8) reported the latest number of cases of Legionnaires' disease (LD), and stressed the importance of using and maintaining properly designed man-made water systems, adding that susceptible groups should strictly observe relevant precautions.
From June 30 to July 6, the CHP recorded one community-acquired LD case, involving a male patient, aged 57 with underlying illnesses, who lives in Islands District.
"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 July 6, 52 LD cases had been recorded this year. In 2023 and 2022, there were 121 and 80 cases respectively.
"Men, people aged over 50, smokers, alcoholics and persons with weakened immunity are more susceptible to LD. Some situations may also increase the risk of infection, including poor maintenance of water systems; living in areas with old water systems, cooling towers or fountains; using electric water heaters, whirlpools and spas or hot water spring spas; and recent stays in hotels or vessels," the spokesman said.
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 become infected when they breathe in contaminated droplets (aerosols) and mist generated by artificial water systems, or when handling garden soil, compost and potting mixes.
Immunocompromised persons should:
The public should observe the health advice below:
