DH announces latest situation of Legionnaires' disease cases

The Centre for Health Protection (CHP) of the Department of Health today (May 6) 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 April 27 to May 3, the CHP recorded two community-acquired LD cases. The details of the cases are as follows:

  • A 76-year-old male patient with underlying illnesses livingin Tuen Mun District; and

  • A 78-year-old male patient with underlying illnesses living in Central and Western District.

The CHP is conducting epidemiological investigations to identify potential sources of infection, high-risk exposure and clusters, if any.

As of May 3, 44 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.

EDB reminds parents to choose primary schools under Central Allocation process for their children

The Education Bureau (EDB) today (January 12) reminded parents that children who have joined the Primary One Admission (POA) System for 2026 but have not yet secured a discretionary place can take part in the Central Allocation process for a Primary One (P1) place in a government or aided primary school. Parents concerned should make their choice of schools within the period from January 19 to 25.

Digitalisation of POA

---------------------------

In line with the Smart Government strategy, the EDB has fully implemented digitalisation of the POA. Parents who have registered as POA e-Platform (ePOA) users and have bound their account to "iAM Smart+" may submit the Choice of Schools Form for Central Allocation from January 19 to 25 through the ePOA. Please refer to the related videos and Parent's Guide on the EDB's website (www.edb.gov.hk/en/edu-system/primary-secondary/spa-systems/primary-1-admission/poa_eplatform/index.html) for details of the procedures for activating and logging into an ePOA account and for making school choices for the Central Allocation of POA via the e-Platform.

Making school choices at Central Allocation Centres

-----------------------------------------------------------------

The EDB will send letters to parents on January 14 inviting them to make their choice of schools. To cater for the needs of different parents, parents can still submit the Choice of Schools Form in paper form by visiting the designated Central Allocation Centre at the suggested time slot (i.e. 9.30am to 12.30pm or 1.30pm to 4.30pm on January 24 (Saturday) or 9.30am to 12.30pm on January 25 (Sunday)) stated in the letter.

Parents who are ePOA users may choose to submit the Central Allocation Application via the ePOA or in paper form to the Central Allocation Centre but should not submit duplicate applications. Parents who have not yet received the letter by January 19 should call the School Places Allocation Section of the EDB (Hotline: 2832 7700) as soon as possible.

Only one parent of an applicant child is required to complete the school choice-making procedures. Parents are advised not to take their children to the Central Allocation Centre if possible. Parents who cannot make school choices within the suggested time slot can go to the designated Central Allocation Centre from 1.30pm to 4.30pm on January 25. The Choice of Schools Form will be sent together with the letter to parents who have submitted a paper Application Form at the Discretionary Places stage for filling out in advance.

In the event of adverse weather or other special conditions on any day during the period of making school choices, please pay heed to radio or television announcements on the relevant special arrangements.

Unable to submit application within specified choice-making period

------------------------------------------------------------------------------------

For individual parents who are unable to use the ePOA or go to the Central Allocation Centre to make school choices, they can authorise in writing a representative to bring the completed Choice of Schools Form and their signed Letter of Authorisation to the Central Allocation Centre to proceed with the related procedures.

To apply for POA 2026 for their children after January 25, parents need to complete necessary procedures with the School Places Allocation Section, which will separately arrange P1 places for the applicant children in June.

Change of residential address

--------------------------------------

An EDB spokesman reminded parents that, if they have recently moved their residence or have such plans in the near future, they are required to inform the School Places Allocation Section as soon as possible so that they can make school choices in the POA School Net where their new home is located. Parents should fill in the actual residential address of their child. If they provide a false address for securing a P1 place, the POA application of their child will be rendered void and the P1 place allocated will be withdrawn.

The EDB has put in place a monitoring mechanism to verify the residential addresses of applicant children as given by the parents. Random checks have also been stepped up. The public may call the School Places Allocation Section to report suspected cases of using a false address by parents for their children's POA application. The EDB will take action against false address cases.

Mechanism of Central Allocation

----------------------------------------

Central Allocation is composed of two parts. Part A, which takes up 10 per cent of the P1 places earmarked for Central Allocation, is for unrestricted school choices. Parents can choose up to three government or aided primary schools in any school net. Part B takes up the remaining 90 per cent of the P1 places earmarked for Central Allocation. Parents of applicant children residing in the school net concerned are to select schools from the "Choice of Schools List for Central Allocation (Primary One Admission 2026)" of their school net, while parents of applicant children who intend to commute daily to schools in Hong Kong are to select schools from the "2026 Choice of Schools List for Central Allocation (For Applicant Children who intend to commute daily to schools in Hong Kong)". Parents should fill in the Choice of Schools Form in the order of their preference.

The mechanism of the Central Allocation is based on parents' choices in general. The computer-programmed allocation will first process the school choices in Part A and then the school choices in Part B. For oversubscribed schools, the order of priority in allocating places will be determined by random numbers generated by the computer for individual applicants to ensure fairness.

For information about the procedures for Central Allocation, please call the EDB's 24-hour automatic telephone enquiry service at 2891 0088.

Release of Central Allocation results

----------------------------------------------

For parents who have already activated their ePOA account via "iAM Smart" or "iAM Smart+", they will receive their Central Allocation results through the ePOA from 10am on June 3. Parents who wish to receive the allocation results via SMS on June 3 may choose such an option in the Choice of Schools Form. In addition, the allocation results will be sent to parents by post on June 3 and 4.
