DH announces latest situation of Legionnaires' disease cases
The Centre for Health Protection (CHP) of the Department of Health (DH) today (February 16) reported the latest number of Legionnaires' disease (LD) cases, 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 February 8 to 14, the CHP recorded two community-acquired LD cases. Both patients involved had underlying illnesses. The details of the cases are as follows:
a 72-year-old female patient living in Central and Western District; and
a 66-year-old male patient living in Kwun Tong District.
The CHP is conducting epidemiological investigations to identify potential sources of infection and high-risk exposure. Initial investigations revealed that these are sporadic cases. No epidemiological linkages have been established between these two cases and other confirmed cases previously recorded in Hong Kong.
As of February 14, nine LD cases had been recorded this year. In 2025 and 2024, there were 167 and 135 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, whirlpool spas or hot water spring spas; and recent stays in hotels or ships.
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, whirlpool spas, water fountains, humidifiers and home respiratory devices 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) or less 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.
The public may visit the CHP'sLD page, theCode of Practice for Prevention of LDand theHousekeeping Guidelines for Cold and Hot Water Systems for Building Managementof the Prevention of LD Committee, and the CHP'srisk-based strategyfor prevention and control of LD.
Additionally, as smokers and alcoholics are more susceptible to LD, the Government urgesmembers of the public to quit smoking and avoid drinking. Members of the public may call the DH Integrated Smoking Cessation Hotline at 1833 183, which is answered by registered nurses who provide professional counselling and referral to a wide range of free smoking cessation services. The public may also visit the smoking cessation thematic website (www.livetobaccofree.hk) for more information on smoking cessation. The DH has also launched the Pilot Alcohol Cessation Counselling Service, which provides free counselling to people identified as having probable alcohol dependence, through a subvented non-governmental organisation, the Tung Wah Group of Hospitals (TWGHs). Information on the service has been uploaded to the DH'sChange for Healthwebsite. Eligible persons who are interested can call the enquiry hotline of the TWGHs (2884 9876).

DH steps up inspections to premises offering RGA hair growth or platelet-rich plasma services to safeguard public health
In light of the recent investigation by the Department of Health (DH) that some shops are suspected of performing Regenera Activa hair growth (an autologous cell transplant medical procedure, referred as RGA) or platelet-rich plasma injections, contravening the Private Healthcare Facilities Ordinance (Cap. 633) (the Ordinance) which prohibits operating a day procedure centre (DPC) without a licence, the DH today (February 16) visited over 30 shops in Hong Kong which claimed to offer similar services in their websites and conducted investigations if the shops involved illegal acts of operating a DPC without a licence to safeguard public health.
During the operation, no RGA or platelet-rich plasma medical procedures were found to be conducted at the shops. Some of the shops would arrange customers to undergo the relevant medical procedures at licensed DPCs. Nevertheless, the DH has reminded the responsible persons of the shops that, according to the Ordinance, transplantation of any cells, tissues or organs, including autograft, allograft, xenograft, processed tissue or blood products (such as platelet-rich plasma) and skin flap, are scheduled medical procedures stipulated in the Ordinance. Such procedures, when performed in an ambulatory setting, must take place in a licensed DPC. The DH has also issued a letter to remind all registered doctors and dentists of the abovementioned legal requirements. Any person operating a DPC without a licence commits an offence and is liable on conviction to a fine of $100,000 and imprisonment for three years.
The DH announced last week that a shop in Mongkok offering RGA hair growth services and platelet-rich plasma injections was suspected of operating a DPC without a licence, the relevant investigation and evidence collection are still ongoing. The DH will seriously follow up on the case, and take appropriate actions against the shop and its responsible persons in accordance with the relevant ordinances.
The DH reminded doctors that before performing RGA, platelet-rich plasma injection or other scheduled medical procedures stipulated in the Ordinance, they must verify that the premises holds a suitable licence, so as to ensure the best interests of patients and adhere to the Code of Professional Conduct.
Meanwhile, the DH urged the public that before receiving RGA or platelet-rich plasma injection or other scheduled medical procedures stipulated in the Ordinance, they should find out if the premises providing the services had obtained a DPC licence in accordance with the Ordinance. To assist the public in identifying licensed or exempted facilities, the DH has established thePrivate Healthcare Facilities Register, which lists all private healthcare facilities with valid licences and exemptions. DPCs must display their licence in a conspicuous place. Each licence bears a QR code that can be scanned using the eHealth app to verify its validity. For more information, please visit the DH's Office for Regulation of Private Healthcare Facilitieswebpage.
