CHP investigates cluster of Legionnaires’ disease in community

     The Centre for Health Protection (CHP) of the Department of Health is today (December 4) investigating a cluster of Legionnaires’ disease (LD) cases, involving three patients, and stressed the importance of using and maintaining properly designed man-made water systems and that susceptible groups should strictly observe relevant precautions.

     The CHP announced two community-acquired LD cases on November 26, involving a 61-year-old male patient and a 76-year-old female patient. The CHP’s subsequent genetic analysis of the Legionella pneumophila serogroup 1 culture isolate from the respiratory specimens of the two patients revealed an identical sequence-based type.
 
     Subsequently, one additional community-acquired LD case was recorded by the CHP. The male patient, aged 69 with underlying illnesses, lives in Tower 3A, The Wings IIIA, 19 Tong Yin Street, Tseung Kwan O. Genetic analysis of the infecting bacterial strain is in progress.

     “Epidemiological investigations revealed that the three patients had no travel history in the incubation period (IP). However, they all either resided in or visited The Wings IIIA in the IP. Investigations are ongoing to identify potential sources of infection, if any,” a spokesman for the CHP said.

     “The CHP has already collected relevant water samples from potential sources, namely a water fountain at the main entrance and a waterfall between Towers 2 and 3, in The Wings IIIA for testing. As a precautionary measure, the management office of The Wings IIIA suspended the operation of the water fountain and the waterfall,” the spokesman added.
 
     “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 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 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 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:
     1. Wear gloves and a face mask;
     2. Water gardens and compost gently using low pressure;
     3. Open composted potting mixes slowly and make sure the opening is directed away from the face;
     4. Wet the soil to reduce dust when potting plants; and
     5. Avoid working in poorly ventilated places such as enclosed greenhouses.

CHP investigates influenza A outbreak at primary school in Southern District

     The Centre for Health Protection (CHP) of the Department of Health is today (December 4) investigating an influenza A outbreak at a primary school in Southern District, and again reminded the public to maintain strict personal and environmental hygiene against influenza.
 
     The outbreak involves nine boys and nine girls aged 5 to 8, as well as three female staff members, who developed cough, sore throat and fever since November 22. All of them sought medical attention. Among them, one student required hospitalisation and was discharged following treatment. All patients are now in a stable condition.
 
     The respiratory specimens of eight students and three staff members tested positive for influenza A virus. 

     Officers of the CHP have conducted a site visit and advised the school to adopt necessary infection control measures against respiratory infections. The school has been put under medical surveillance.
 
     A spokesman for the CHP said, “To prevent outbreaks of influenza and other respiratory infections, it is of prime importance that children with fever, regardless of the presence of respiratory symptoms, should not be allowed to attend school. They should seek medical advice and avoid school till 48 hours after the fever has subsided. Schools should also measure and record students’ body temperature properly.”

     Schools are reminded to follow the Guidelines on Prevention of Communicable Diseases on preventive and control measures as well as management of outbreaks, which should be reported to the CHP for prompt follow-up.

      “Influenza can cause serious illnesses in high-risk individuals and even healthy persons. Given that influenza vaccines are safe and effective, all persons aged 6 months or above, except those with known contraindications, are recommended to receive Seasonal Influenza Vaccine(SIV) for personal protection,” the spokesman said.
 
     As it is already December and Hong Kong will soon enter the winter influenza season, eligible persons are urged to receive SIV early for protection against seasonal influenza as it takes about two weeks to develop antibodies. Vaccination among family members is key to protecting their personal and family’s health.”
 
     Besides receiving seasonal influenza vaccine for personal protection, the public should maintain good personal and environmental hygiene for protection against influenza and other respiratory illnesses.

A gloomy and warm November

     As the northeast monsoon affecting the south China coast was relatively weak, southerlies dominated in the lower atmosphere and water vapour built up, causing Hong Kong’s weather in November 2018 to be cloudier and gloomier than usual. The mean amount of cloud in the month was 79 per cent, 25 per cent above the normal figure of 54 per cent – the highest on record for November. The duration of bright sunshine in the month was only 123.9 hours, about 31 per cent lower than the normal figure of 180.1 hours and the eighth lowest on record for November. Despite the gloomy weather, the month was warmer than usual. The mean temperature of 22.9 degrees and mean minimum temperature of 21.4 degrees were 1.1 degrees and 1.6 degrees above the respective normal figures, and were the ninth and fourth highest on record for November. The month was also wetter than usual with 73.4 millimetres of rainfall, about 95 per cent above the normal figure of 37.6 millimetres. The accumulated rainfall up to November this year was 2151.0 millimetres, a deficit of about 9 per cent compared to the normal figure of 2371.7 millimetres for the same period.
 
     Tropical cyclone Yutu edged north slowly towards the coast of eastern Guangdong and weakened gradually on November 1 and 2. It eventually dissipated over the northeastern part of the South China Sea in the morning of November 3. Under the combined effect of the northeast monsoon and tropical cyclone Yutu, it was windy and dry with sunny periods in Hong Kong on the first day of November. While local winds subsided gradually, it was mainly cloudy with a few rain patches over the next two days.
 
     Affected by the northeast monsoon, the weather turned windy with a few light rain patches in Hong Kong on November 4. As the cloud band covering the coast of Guangdong dissipated gradually, the weather in Hong Kong became generally fine over the next three days. With a replenishment of the northeast monsoon arriving at the coastal areas of Guangdong in the morning of November 8, there were sunny periods with one or two light rain patches in Hong Kong. The weather turned cloudier and windier with light rain on November 9 and 10 as winds from the east strengthened. With the easterly airstream moderating gradually, there were sunny periods during the day on November 11 and 12. The temperature at the Hong Kong Observatory rose to a maximum of 28.0 degrees in the afternoon of November 12, the highest of the month. Under the influence of the northeast monsoon, winds strengthened on November 13, though the weather remained generally fine apart from a few light rain patches in the morning and at night.
 
     Under the influence of a fresh to strong easterly airstream, the weather in Hong Kong became mainly cloudy again with a few light rain patches from November 14 to 17. The weather improved with sunny periods during the day on November 18. With a replenishment of the northeast monsoon reaching the south China coastal areas, it was slightly cooler with sunny intervals on November 19 and 20.
 
     There were sunny periods during the day in Hong Kong on November 21. As a cold front moved across the coastal areas of Guangdong and winds from the north strengthened, the weather turned cloudy with a few rain patches at night. Affected by the northeast monsoon behind the cold front, the weather became appreciably cooler and drier, with sunny periods from November 22 to 24. With a broad rain-bearing cloud band covering southern China, local weather became cloudy and rainy from November 25 to 28. More than 20 millimetres of rainfall were recorded on November 25. Under the rain, the temperature at the Hong Kong Observatory dropped to a minimum of 17.0 degrees in the morning of November 26, the lowest of the month. With the cloud band thinning out gradually, sunshine returned on the last two days of the month.
 
     Four tropical cyclones occurred over the South China Sea and the western North Pacific in November 2018.
 
     Details of issuance and cancellation of various warnings/signals in November are summarised in Table 1. Monthly meteorological figures and departures from normal for November are tabulated in Table 2. read more
