Hong Kong: A case of necrotising fasciitis confirmed [CHP]

The Centre for Health Protection (CHP) of the Department of Health is investigating a case of necrotising fasciitis (flesh-eating disease) involving a 61-year-old man today (September 17).


The man, living in Wong Tai Sin, reported a painful swelling in his left foot and fever on September 10.

He was admitted to Prince of Wales Hospital on September 13 and is now in critical condition.

Laboratory tests on his wound swab yielded vibrio vulnificus, a type of bacteria that causes necrotising fasciitis.

A CHP spokesman said necrotising fasciitis was a serious bacterial infection of the soft tissue and fascia. It can destroy tissue and cause death within 12 to 24 hours after infection.

Members of the public are reminded to adopt the following preventive measures:
- Avoid exposure of open wounds or broken skin to sea water or salty water
- Wounds should be thoroughly cleaned and properly covered
- Wear thick rubber gloves when handling raw shellfish

Patients should seek medical advice promptly if symptoms and signs of infection like increasing redness, pain and swelling are found.

Hong Kong: Public urged to be vigilant against bacillary dysentery [CHP]

The Centre for Health Protection (CHP) of the Department of Health today (September 18) urged members of the public to observe personal and food hygiene following the notification of 19 cases of laboratory-confirmed bacillary dysentery (shigellosis) so far this month.


Initial investigations by the CHP indicated that 18 of these cases acquired infection locally while the remaining one was an imported case. These cases, comprising 10 females and nine males aged between two and 58, developed gastrointestinal symptoms including fever, diarrhoea, vomiting and abdominal pain from August 26 to September 12. All of them have recovered and their stool samples were positive for Shigella sonnei.

Their family contacts presently do not have any symptoms.Health advice has been given to them.

According to the food histories provided, five of the local cases,involving two males and three females aged from two to 28 who did not know each other, had taken meals from a fast food restaurant in Tsuen Wan one to four days before the onset of symptoms. Further investigations are underway.

There were 17, 17 and six cases in September of 2005, 2006 and 2007 respectively.

Bacillary dysentery is an intestinal infection caused by a group of Shigella bacteria which can be found in the human gut. The illness is characterised by the sudden onset of fever, diarrhoea with abdominal cramps and nausea or vomiting. The stool may contain blood and mucus. The incubation period usually lasts for one to three days, but can be up to seven days. The disease is transmitted directly by faecal material of a patient/carrier or indirectly through contaminated food and water. Infection may occur after consuming a small number of the germs. The infection can spread among household members or in institutions.

The public are reminded to observe good personal, food and environmental hygiene at all times to prevent food-borne diseases.

When dining out:
* Only patronise reputable and licensed restaurants;
* Do not patronise illegal food hawkers;
* Cook food thoroughly;
* Avoid eating raw seafood;
* Be a discerning consumer in choosing cold dishes, including sashimi and raw oysters in a buffet;
* Drink boiled water;
* Use two sets of chopsticks and eating utensils to handle raw and cooked food;
* Do not try to use salt, vinegar, wine and wasabi to kill bacteria as they are not effective;
* Always wash hands before eating and after going to toilet.

Hong Kong: Case of Streptococcus suis infection under investigation [CHP]

The Centre for Health Protection (CHP) of the Department of Health is today (September 25) investigating a case of laboratory confirmed infection of Streptococcus suis, a kind of bacteria isolated from pigs.


The case involved a 50-year-old man living in Sham Shui Po who developed fever, back pain and left shoulder pain on September 18. He was admitted to Caritas Medical Centre two days later and is now in stable condition. A CHP spokesman said the patient had no recent travel history. His home contacts did not have any symptoms.

This is the fourth reported case of Streptococcus suis infection in 2008.

Six cases were reported in 2007, eight in 2006 and 13 in 2005.

The spokesman said Streptococcus suis infection may present as meningitis (inflammation of the membrane enclosing the brain), septicaemia (blood stream infection), and less commonly endocarditis (inflammation of the inner lining of the heart chambers), arthritis and bronchopneumonia (a kind of lung infection involving the bronchioles).

Streptococcus suis infection could be treated with appropriate antibiotics.

To prevent the disease, people are advised to always observe personal and environmental hygiene practices and avoid contact with pigs that are sick or dead from diseases and their excreta or body fluid. If contact with pigs or raw pork is necessary, one should:

- Use protective gloves;
- Wash hands after handling pigs or raw pork; and

Re: Hong Kong, PRC SAR: Epi-Surveillance (September 2008, Govt Press Releases)

Hong Kong: A probable case of classical Creutzfeldt-Jakob Disease in Pamela Youde Nethersole Eastern Hospital [CHP]

The following is issued on behalf of the Hospital Authority: In response to media enquiries about a probable case of classical Creutzfeldt-Jakob Disease (CJD), the spokesperson of Pamela Youde Nethersole Eastern Hospital (PYNEH) gave the following reply today (October 2):


A female patient, aged 83, was admitted to the medical ward through the Accident and Emergency Department (AED) of PYNEH on August 8, 2008 for recurrent episodes of positional vertigo with tinnitus and hearing impairment.

Her condition continued to deteriorate afterwards, with deteriorating cognitive function, occasional confused speech and twitching of the face and limbs. She passed away on September 22.

Clinical presentations and Electro-encephalogram (EEG) screening confirmed it was a probable case of classical Creutzfeldt-Jakob Disease (CJD).

Further confirmation has to be made through post-mortem investigation.

Hospital record shows that the patient received a cataract operation in PYNEH on January 8, 2004.

Although the surgical instruments had undergone thorough sterilization process according to protocol after each operation, the risk of cross-contamination, which is extremely low, could not be absolutely eliminated as Prion-Protein is unlikely to be inactivated by normal sterilization procedure as indicated in some literature and by specialist advice on CJD.

Upon retrieval of surgery records, there are 10 patients who had undergone cataract from January 9 to 13, 2004 and might have contacts with related surgical instruments. PYNEH has started to contact affected patients and their families.

They will be given an explanation about the case and informed of the extremely low potential exposure to the risk of CJD by being operated on with those identified instruments. So far there is no reported case of transmission of CJD through cataract surgery.

However, as a prudent step for precaution, PYNEH would arrange related investigations and follow-up for them.

The post-mortem finding of the case and the concerned 10 patients will be under close surveillance of PYNEH.

CJD is one form of transmissible spongiform encephalopathies (TSE) and a very rare degenerative brain disease. No cause can be determined for most of the cases, with some caused by faulty Prion-Proteins.

In the early stages of the disease, CJD patients may exhibit failing memory, behavior changes and other dementia-like symptoms. As the illness progresses, involuntary twitching of limbs, visual disturbances, dyasesthesia and seizures becomes more pronounced.

Variant CJD (vCJD, also know as "Mad-cow Disease") is also caused by faulty Prion-Proteins, but with a higher risk for transmission than classical CJD. The cause of vCJD is probably consumption of meat products and internal organs of infected cattle.

A Task Force has been set up by PYNEH to oversee the necessary follow up actions. The case has been reported to the Hospital Authority Head Office and the Centre for Health Protection for necessary follow up.

Hong Kong: Travellers urged to be vigilant against viral hepatitis [CHP]

The Centre for Health Protection (CHP) of the Department of Health today (October 9) called on people travelling to viral hepatitis endemic areas, to be vigilant against infection following the confirmation of six sporadic cases of hepatitis A infection involving children who had recently travelled to Pakistan.


The six cases involved four boys and two girls aged between 7 and 12. They developed symptoms of fever, vomiting, abdominal pain, loss of appetite and jaundice between September 5 and October 1. They sought treatment at public hospitals and are in stable condition.

One of them, a 12-year-old boy, is still being treated at Queen Elizabeth Hospital.

CHP's investigations revealed that they had travelled to Pakistan within six weeks before the onset of symptoms.

CHP has contacted the six schools they are attending and learnt that there were no other cases in these schools.

CHP has given health advice to the school managements.

The Port Health Office of the department has informed the tourism industry of the cases and the Pakistan Consulate has also been alerted.

A CHP spokesman said hepatitis A was one form of viral hepatitis and was transmitted by faecal-oral route through contaminated food, drinks and shellfish or directly from person-to-person.

"The incubation period of the disease is usually around four weeks but may range from 15 days to 50 days.
"Affected persons of Hepatitis A may be asymptomatic. Those who have symptoms may have poor appetite, tiredness, nausea, vomiting, diarrhoea, fever, upper abdominal discomfort, jaundice and tea-coloured urine.
"The illness lasts a few weeks but may sometimes last months. Most patients have a complete recovery but in a few cases, the damage on the liver may be prolonged. Immunity is usually life-long and there is no chronic carrier state," the spokesman said.

People looking after patients with viral hepatitis should wear gowns if soiling is likely and they should used gloves when handling contaminated materials.

Patients will usually be given conservative treatment such as bed rest.

The spokesman appealed to the public, in particular people travelling to areas with viral hepatitis, to observe good personal hygiene and food hygiene to prevent infection.

"People should always wash their hands before preparing food, before meals and after going to toilet. They should also avoid drinking contaminated water or beverage with ice of doubtful origin, eating uncooked or undercooked food, particularly shellfish, and eating cut or peeled fruit.
"These measures can also effectively prevent other infectious food-borne illness," the spokesman said.

The spokesman said hepatitis A vaccine should be considered for travellers visiting high risk areas.

"It is used in those two years or older. The vaccine is administered in two doses six months apart. Protection against hepatitis A begins four weeks after the first dose.
"It is safe and does not cause serious side effects. Current evidence suggests that the protection of hepatitis A vaccination lasts for at least 10 years," he said.

Hong Kong: A confirmed case of dengue fever [CHP]

The Centre for Health Protection (CHP) of the Department of Health today (October 10) urged people to guard against dengue fever following the confirmation of a case by laboratory test.


The case involved a 30-year-old tourist who arrived at Hong Kong on October 2. He developed fever, muscle pain and eye pain on October 1. He sought medical treatment from a private doctor on October 2 and later was admitted to Princess Margaret Hospital. He was discharged on Tuesday (October 7).

CHP's investigations revealed that he had travelled to Malaysia between September 20 and 26 and Taiwan between September 28 and October 1. His home contacts in Malaysia also developed dengue fever but his travel collateral was asymptomatic.

A total of 34 cases of dengue fever have been reported to the CHP so far this year. Last year, 58 cases were reported and all were classified as imported cases.

A spokesman for CHP urged the public to stay alert to the threat of dengue fever and to help prevent mosquito breeding by taking the following measures:
* Put all used cans and bottles into dustbins with covers;
* Change water for plants at least once a week, leaving no water in the saucers underneath flower pots;
* Tightly cover all water containers, wells and water storage tanks, and
* Keep all drains free from blockage.

Travellers should take the following preventive measures:
* Wear long-sleeved tops and trousers;
* Use insect repellent on the exposed parts of the body, and
* Use mosquito screens or nets when rooms are not air-conditioned.

Anyone feeling unwell after returning from their trip should consult a doctor as soon as possible and provide details of their travel to the doctor.
