Update on cases of Legionnaires’ disease

     The Centre for Health Protection (CHP) of the Department of Health today (June 11) reported the latest number of cases of Legionnaires’ disease (LD), and stressed the importance of using and maintaining properly designed man-made water systems, and that susceptible groups should strictly observe relevant precautions.

     From June 3 to 9, one community-acquired LD case was reported. The 64-year-old male patient, with good past health, lives in Elegant Court, Phase 2, Pictorial Garden, 23 On King Street, Sha Tin District.

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

     As of June 9, 22 LD cases had been reported in 2018. In 2017 and 2016, there were 72 and 75 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 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.

     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 which support breathing. People may get 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. A shower may also generate small aerosols; and
  • If using these devices, fill the water tank with only sterile or cooled freshly boiled water, and not tap water. Also, clean and maintain them regularly according to manufacturers’ instructions. Never leave stagnant water. 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;
  • Remove strainers in water taps and shower heads quarterly for cleaning;
  • 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 they need to be changed periodically;
  • Drain and clean water tanks of buildings at least quarterly;
  • Drain or purge for at least one minute the 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 medical advice regarding the use and maintenance of home respiratory devices and use only sterile (not distilled or tap) water to clean and fill the reservoir. Clean and maintain them 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. Empty the water tank, keep all surfaces dry, and change the water daily; and
  • When handling garden soil, compost and potting mixes:
1. Water gardens and compost gently using low pressure;
2. Open composted potting mixes slowly and make sure the opening is directed away from the face;
3. Wet the soil to reduce dust when potting plants; and
4. Avoid working in poorly ventilated places such as enclosed greenhouses.

Office of The Ombudsman announces results of direct investigation into Immigration Department’s mechanism for following up on cases of unregistered birth

The following is issued on behalf of the Office of The Ombudsman:
      
     The Ombudsman, Ms Connie Lau, today (June 11) announced the completion of a direct investigation into the mechanism for following up on cases of unregistered birth by the Immigration Department (ImmD). The investigation report has been uploaded to the Office of The Ombudsman website at www.ombudsman.hk for public viewing. 
      
     A tragedy happened in Hong Kong in which a 15-year-old girl plunged to her death from a building. It was later discovered that the girl and her younger sister were born in Hong Kong, but their parents had never registered their births. In view of the public outcry arising from the incident, the Office decided to launch this direct investigation.
      
     The Office’s investigation found that prior to the tragic incident, ImmD’s follow-up actions on cases of unregistered birth were feeble and ineffective. The department only sent out reminders in a routine manner to alert the parents concerned but never referred such cases to its Investigation Division, let alone instituted any prosecution. The situation was extremely undesirable as the follow-up procedure under ImmD’s old mechanism was tantamount to inaction. In the wake of the tragedy, ImmD immediately reviewed its practice and introduced a new follow-up mechanism. Nevertheless, upon examination, the Office found that there is still room for further improvement. In particular, the cases often involve complicated family problems and call for the department’s early intervention.
      
     In this light, the Office made four recommendations to ImmD for improvement:
   

  1. to collaborate with hospitals to solve the problem of incomplete address on birth returns;
  2. to initiate early intervention in cases of unregistered births;
  3. to enhance its public education campaign; and
  4. to examine possible ways to strengthen the existing follow-up mechanism, including the feasibility of establishing a mandatory notification mechanism.

     The department has accepted all the recommendations and implemented some already. read more
