Cluster of Candida auris Cases Found in Elderly Care Home Sparks Concern

CHP follows up on cluster of Candida auris carrier cases

The Centre for Health Protection (CHP) of the Department of Health is today (August 12) following up on a cluster of Candida auris carrier cases announced earlierinvolving a residential care home for the elderly (RCHE) in Sha Tin, with a new case recorded. The CHP reminded members of the public about the proper use of antimicrobials and maintaining personal hygiene against infection.

The CHP received notification from the Hospital Authority (HA) that an 83-year-old male resident of the aforementionedRCHE, who was earlier admitted to Prince of Wales Hospital, was confirmed to have carried Candida auris upon testing. The patient, with underlying illnesses, has no symptoms of infection and is in stable condition. Epidemiological investigations by the CHP revealed that the patient shared the same room with one of the cases (another 83-year-old male patient) of the cluster at the RCHE that was earlier announced (involving two cases related to clusters of Candida auris cases in Prince of Wales Hospital and Shatin Hospital as well as one infection case at the RCHE). Currently, the Candida auris carrier cases cluster of the RCHE concerned involves two patients, including the case announced today. The two other patients earlier announced had passed away due to their underlying medical conditions.

The CHP has immediately carried out follow-up actions and site inspection at the RCHE, and found that the physical limitations at the RCHE have contributed to the transmission of Candida auris in the RCHE. In light of the new case in the RCHE, the CHP has informed the Social Welfare Department and the Community Geriatric Assessment Team of the HA to strengthen the relevant support to the RCHE and assist the RCHE to implement appropriate infection control measures. The epidemiological investigation of the CHP is ongoing.

Apart from the follow-up measures mentioned above, the CHP has again provided infection control advice and training to staff of the RCHE. The RCHE is advised to follow the prevailing guidelines to enhance infection control measures, including appropriate placement of carrier residents, strict implementation of contact precautions, enhancement of environmental cleansing and disinfection, and the use of dedicated medical equipment, toilet and bathing facilities, to prevent the spread of Candida auris. The CHP will keep in close liaison with the RCHE concerned, monitor the situation of the residents and ensure the RCHE has carried out the various infection control measures.

A spokesman for the CHP explained that Candida is a fungus commonly found in the natural environment, particularly in moist and warm environments. In humans, it is commonly found in body sites such as the oral cavity, the digestive tract, the skin and the vagina. It is a common fungus living on or in the human body but can occasionally cause infections, especially in individuals with impaired immunity.

​Among the different candida species, Candida auris is more drug-resistant. Infections vary from being mild to potentially life-threatening or fatal, depending on which part of the body is affected and the general health condition of the patient. The spokesman stressed that proper use of antimicrobials and maintaining personal hygiene, especially hand hygiene, are crucial to the prevention of the emergence and cross-transmission of Candida auris.

CHP reminds public on precautions against heat stroke during very hot weather

The Centre for Health Protection (CHP) of the Department of Health (DH) today (September 13) reminded members of the public, particularly those undertaking outdoor activities, to take heed of necessary measures against heat stroke and sunburn in very hot weather.

"The public should carry and drink plenty of water to prevent dehydration while engaging in outdoor activities," a spokesman for the CHP said.

"Those engaged in strenuous outdoor activities should avoid beverages containing caffeine, such as coffee and tea, as well as alcohol, as they speed up water loss through the urinary system," the spokesman explained.

"Infants and children, the elderly, pregnant women, those with chronic illnesses such as heart disease or high blood pressure, outdoor/manual workers, and individuals who are overweight are more vulnerable to heat stroke. They should pay special attention," the spokesman added.

The public should adopt the following precautions:

​The public should also note the latest and the forecast Ultraviolet (UV) Index released by the Hong Kong Observatory (HKO). When the UV Index is high (6 or above):

​If symptoms develop, such as dizziness, headache, nausea, shortness of breath or confusion, rest and seek help immediately, and seek medical advice as soon as possible.
