DH announces latest situation of Legionnaires' disease cases
The Centre for Health Protection (CHP) of the Department of Health today (September 22) reported the latest number of cases of Legionnaires' disease (LD), and reminded the public of the importance of using and maintaining properly designed man-made water systems, adding that susceptible groups should strictly observe relevant precautions.
From September 14 to 20, the CHP recorded three community-acquired LD cases. The details of the cases are as follows:
an 84-year-old female patient with underlying illnesses living in Kowloon City District;
a 68-year-old female patient with good past health living in Tsuen Wan District; and
a 61-year-old female patient with underlying illnesses living in Tai Po District.
The CHP is conducting epidemiological investigations to identify potential sources of infection and high-risk exposure. Initial investigations revealed that all three cases are sporadic cases. No epidemiological linkages have been established between these cases and other confirmed cases previously recorded in Hong Kong.
As of September 20, 124 LD cases had been recorded this year. In 2024 and 2023, there were 135 and 121 LD 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.
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:
Use sterile or boiled water for drinking, tooth brushing and mouth rinsing;
Avoid using humidifiers, or other mist- or aerosol-generating devices; and
If using humidifiers, or other mist- or aerosol-generating devices, fill the water tank with only sterile or cooled freshly boiled water, and not water directly from the tap. Also, clean and maintain humidifiers/devices regularly according to manufacturers' instructions. Never leave stagnant water in a humidifier/device. Empty the water tank, wipe all surfaces dry, and change the water daily.
The public should observe the health advice below:
Observe personal hygiene;
Do not smoke and avoid alcohol consumption;
Strainers in water taps and shower heads should be inspected, cleaned, descaled and disinfected regularly or at a frequency recommended by the manufacturer;
If a fresh-water plumbing system is properly maintained, it is not necessary to install domestic water filters. Use of water filters is not encouraged as clogging occurs easily, which can promote growth of micro-organisms. In case water filters are used, the pore size should be 0.2 micrometres (µm) and the filter needs to be changed periodically according to the manufacturer's recommendations;
Drain and clean water tanks of buildings at least quarterly;
Drain or purge for at least one minute infrequently used water outlets (e.g. water taps, shower heads and hot water outlets) and stagnant points of the pipework weekly or before use;
Seek and follow doctors' professional advice regarding the use and maintenance of home respiratory devices and use only sterile water (not distilled or tap water) to clean and fill the reservoir. Clean and maintain the device regularly according to the manufacturer's instructions. After cleaning/disinfection, rinse the device with sterile water, cooled freshly boiled water or water filtered with 0.2 µm filters. Never leave stagnant water in the device. Empty the water tank, keep all surfaces dry, and change the water daily; and
When handling garden soil, compost and potting mixes:
Wear gloves and a face mask;
Water gardens and compost gently using low pressure;
Open composted potting mixes slowly and make sure the opening is directed away from the face;
Wet the soil to reduce dust when potting plants; and
Avoid working in poorly ventilated places such as enclosed greenhouses.

Secretary for Health attends 20th Joint Meeting of Senior Health Officials of Mainland, Hong Kong and Macao in Macao
The Secretary for Health, Professor Lo Chung-mau, led a delegation to attend the 20th Joint Meeting of Senior Health Officials of the Mainland, Hong Kong and Macao hosted by the Macao Special Administrative Region (SAR) Government in Macao today (January 15).
The annual Joint Meeting has long been a platform for senior medical and health officials as well as experts from the Mainland, Hong Kong and Macao to exchange views and share experiences on present-day medical and public health issues, as well as to promote healthcare service development. The Joint Meeting is hosted by the Mainland, Hong Kong and Macao in rotation.
The Minister of the National Health Commission, Mr Lei Haichao, and the Secretary for Social Affairs and Culture of the Macao SAR Government, Ms O Lam, led senior health officials from the Mainland and the Macao SAR Government respectively to participate in the meeting. Members of the delegations of the three places today engaged in sharing and discussions over three major topics, namely nurturing interdisciplinary and composite talent in clinical management, disease prevention and control, and medical administration; strengthening primary healthcare services to safeguard community health, and the application of smart healthcare in the health sector.
Professor Lo said, "The Recommendations of the Communist Party of China (CPC) Central Committee for Formulating the 15th Five-Year Plan for National Economic and Social Development, adopted at the Fourth Plenary Session of the 20th CPC Central Committee, features the term 'reform' 23 times, unequivocally underscoring the nation's steadfast commitment to deepening reforms. Hong Kong has consistently been playing an active role in the course of the country's reform and opening up. Serving as a 'super connector' between the Mainland and the world, Hong Kong also functions as an indispensable 'super value-adder', facilitating the nation's effort in going global while attracting foreign investment to the Mainland market.
"The Chief Executive of the Hong Kong Special Administrative Region (HKSAR) has consistently emphasised in the Policy Addresses of the past three years the HKSAR Government's full commitment to developing Hong Kong into an international health and medical innovation hub, and to vigorously foster new quality productive forces. To achieve this significant objective, the HKSAR Government is actively advancing various initiatives, including the setting up of the Hong Kong Centre for Medical Products Regulation within this year, with a view to establishing the Centre as an internationally recognised regulatory authority for medical products as soon as possible; the official launch of the Greater Bay Area (GBA) Clinical Trial Collaboration Platform last month, enabling pharmaceutical companies to conduct trials simultaneously in Hong Kong and Shenzhen; as well as the commissioning of the Real-World Study and Application Centre to promote the standardisation of clinical data across the GBA."
The Chief Executive of the Hospital Authority (HA), Dr Libby Lee, and the Director of Cluster Services of the HA, Dr Wong Yiu-chung, moderated a discussion and gave a presentation on the application of smart healthcare in the health sector respectively. Meanwhile, the acting Deputy Director of Health, Dr Jackie Leung, and the Commissioner for Primary Healthcare, Dr Pang Fei-chau, delivered presentations on the topic of nurturing interdisciplinary and composite talent in clinical management, disease prevention and control, and medical administration; as well as on the topic of strengthening primary healthcare services to safeguard community health respectively.
Members of the HKSAR Government delegation included the Chairman of the HA, Mr Henry Fan, and the Director of Health, Dr Ronald Lam, who concluded the discussion at the meeting.
Professor Lo will return to Hong Kong in the evening. During his absence, the Under Secretary for Health, Dr Cecilia Fan, is the Acting Secretary for Health.
