DH announces latest situation of Legionnaires' disease cases
The Centre for Health Protection (CHP) of the Department of Health today (June 2) 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 May 25 to 31, the CHP recorded three community-acquired LD cases. The details of the cases are as follows:
A 63-year-old male patient with good past health livingin Yuen Long District;
A 74-year-old male patient with underlying illnesses livingin Kwun Tong District; and
A 63-year-old male patient with underlying illnesses livingin Eastern District.
The CHP is conducting epidemiological investigations to identify potential sources of infection, high-risk exposure and clusters, if any.
As of May 31, 53 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.

Public hospitals experience smooth operations on second day of public healthcare fees and charges reform
The following is issued on behalf of the Hospital Authority:
On the second day (January 2) of the implementation of the Hospital Authority public healthcare fees and charges reform (fees and charges reform), public hospitals maintained smooth operation. The HA will continue to deploy additional manpower across various departments at hospitals to assist patients in need.
On the first day (January 1) of the fees and charges reform, 3 888 patients attended the Accident and Emergency departments (A&E) of 18 public hospitals, a decrease of about 25 per cent when comparing to New Year's Day last year. From midnight to 2pm yesterday (January 2), 2 329 patients attended all A&E, approximately 30 per cent fewer than the same time period of January 2 of last year. Among the patients seeking medical consultation, there were 34 critical cases and 82 emergency cases. According to the new fees and charges arrangement, these two categories of patients will have their A&E charges fully exempted. The other cases subject to the new fees and charges arrangement include 986 urgent cases, 1 171 semi-urgent cases, and 56 non-urgent cases. The average waiting times for semi-urgent and non-urgent cases was around 55 minutes, which is shorter compared to the average waiting time for the same period last year (approximately 147 minutes) for semi-urgent and non-urgent cases.
Additionally, the HA's 75 Family Medicine Clinics (FMCs) providing family medicine outpatient services also operated smoothly yesterday. As of 2pm yesterday, approximately 10 000 patients attended these FMCs, with overall service usage remaining similar to that before the implementation of the measures.
The HA has deployed additional manpower to expedite the processing of patients' medical fee waivers applications. As of 2pm yesterday, public hospitals received approximately 3 300 applications in total for the day, with nearly 90per cent approved, amounting to about 2 900 applications. The remaining cases will be processed as soon as possible. Compared to the 14 000 individuals who were approved for medical fee waivers in 2023/24, the HA has approved approximately 35 000 applications since early November last year, benefiting citizens in need.
Furthermore, patients who had previously scheduled non-urgent radiology services or pathology services will be receiving payment notifications through mail or the HA mobile application HA Go starting from January 1. The HA reminds patients with recent appointments can arrange payment as early as practicable upon receiving the notification. For patients with distant appointment dates, payment can be arranged at their convenience after receiving the notification. Patients are not required to settle the payment immediately. Patients undergoing non-urgent radiology services must settle the payment at least 14 days before their appointment date, while patients requiring pathology services must settle the payment before testing. If patients have questions regarding payment items, they can inquire with healthcare staff during follow-up appointment, and specialist out-patient clinics will also have Integrated Patient Service Centres to provide detailed explanations about payment arrangements.
The HA reminds patients that the fees and charges reform has been implemented. Patients are advised to familiarise themselves with the new fees and charges arrangements before visiting public hospitals or outpatient clinics. Some medical service procedures have also been modified. Every cluster has set up hotlines (see table below) for patients to inquire about the fees and charges reform arrangements. Patients can also visit the HA website to learn about the new arrangements.
