3rd August 2020 – (Hong Kong) The Centre for Health Protection (CHP) of the Department of Health reported today 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 26th July to 1st August, three community-acquired LD cases were reported:

1. A male patient, aged 60 with good past health, who lives in Shun Hei House, Siu Hei Court, Tuen Mun;

2. A female patient, aged 72 with underlying illnesses, who lives in King Wah House, Shan King Estate, Tuen Mun; and

3. A male patient, aged 59 with underlying illnesses, who lives in Block 1, Pierhead Garden, Tuen Mun.

 “Epidemiological investigations are ongoing to identify potential sources of infection, high-risk exposures and clusters, if any,” a spokesman for the CHP said.

As of 1st August this year, 66 LD cases had been reported. In 2019 and 2018, there were 105 cases each year.

 “Men, people aged over 50, smokers, alcoholics and persons with weakened immunities are more susceptible to LD. Some situations may also increase the risk of infection including poor maintenance of water systems leading to stagnant water; 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.
