Breaking news: legionnaires' disease outbreaks and updates
The Centre for Health Protection (CHP) of the Department of Health today (April 22) reported the latest number of cases of Legionnaires' disease (LD), and stressed the importance of using and maintaining properly designed man-made water systems, adding that susceptible groups should strictly observe relevant precautions.
From April 14 to 20, the CHP recorded two community-acquired LD cases and two imported LD cases:
"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 April 20, 23 LD cases had been recorded this year. In 2023 and 2022, there were 121 and 80 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," 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 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:

High-level meeting with japanese officials: urgent concerns over fukushima's nuclear contaminated water discharge
The Secretary for Environment and Ecology, Mr Tse Chin-wan, met the Parliamentary Vice-Minister for Agriculture, Forestry and Fisheries, Mr Takahashi Mitsuo, and the Consul-General of Japan in Hong Kong, Mr Kenichi Okada, today (May 3) upon request and discussed about the discharge of nuclear-contaminated water in Japan.
Mr Tse reiterated at the meeting that the Hong Kong Special Administrative Region (HKSAR) Government has come to the view that there is currently no guarantee from the Japanese authorities that their purification and dilution system can operate continuously and effectively in the long term, and that the discharge will not pose any potential risks to food safety and marine ecology. Safeguarding food safety and public health in Hong Kong is the responsibility of the HKSAR Government, thus corresponding precautionary measures must be taken. The HKSAR Government will closely monitor developments of the discharge, so as to obtain more monitoring and scientific data in order to further examine the impact of the Fukushima nuclear-contaminated water discharge on food safety, and keep under review relevant counter measures. Should anomalies be detected, the Government does not preclude further tightening the scope of the import ban.
In response to the Japanese Government's earlier decision to discharge nuclear-contaminated water at the Fukushima Nuclear PowerStation into the sea, the Director of Food and Environmental Hygiene issued a Food Safety Order which prohibits all aquatic products, sea salt and seaweeds originating from the 10 metropolis/prefectures, namely Tokyo, Fukushima, Ibaraki, Miyagi, Chiba, Gunma, Tochigi, Niigata, Nagano and Saitama, from being imported into and supplied in Hong Kong.For other aquatic products, sea salt, and unprocessed or processed seaweed from Japan that are not prohibited from being imported into Hong Kong, the Centre for Food Safety of the Food and Environmental Hygiene Department will conduct comprehensive radiological tests to verify that the radiation levels of these products do not exceed the guideline levels before they are allowed to be supplied in the market.
Besides, all vegetables, fruits, milk, milk beverages and dried milk originating from Fukushima are banned from importing into Hong Kong while such foods originating from the four prefectures nearby Fukushima, i.e. Ibaraki, Tochigi, Chiba and Gunma, are allowed to be imported on the condition that they are accompanied with a radiation certificate and an exporter certificate issued by the Japanese authority. Chilled or frozen game, meat and poultry, and poultry eggs originating from the above five prefectures are allowed to be imported on the condition that they are accompanied with a radiation certificate issued by the Japanese authority which shows the radiation levels do not exceed the guideline levels of the Codex Alimentarius Commission.
