Hong Kong: Arrival of the winter influenza season in Hong Kong (1/30/2009) [CHP]

The Centre for Health Protection (CHP) of the Department of Health today (January 30) called on people to take precautionary measures against seasonal influenza.


Head of the Emergency Response and Information Branch of the CHP, Dr Thomas Chung, said the Centre had been closely monitoring influenza activity.

Most recent data showed an increasing number of influenza isolates, which signalled the arrival of the winter influenza season. Traditionally, the winter influenza season in Hong Kong tends to arrive between January and March. Influenza virus isolation in the CHP's Public Health Laboratory Centre (PHLC) showed a steady rise, Dr Chung said.

The PHLC recorded 105 influenza detections last week (from January 18-24) as compared with 69 influenza detections from January 12-17.

Dr Chung said CHP also received 10 influenza-like-illness outbreaks in institutions affecting 59 people in the same week and among them, two were confirmed to be caused by influenza. The consultation rates for influenza-like-illness in private doctors and general out-patients clinics (GOPC) have not yet shown obvious signs of increase.

During the week ending January 24, consultation rates for influenza-like illness in private doctors and GOPC were 27.7 and 4.9 per 1000 consultations respectively while the corresponding figures for the week before were 38.5 and 5.2 respectively.

"CHP will monitor these consultation rates in anticipation of their rise over the next few weeks as the flu season progresses," Dr Chung said. He said that as a prudent and preventive measure, the CHP would send letters to doctors, schools and institutions alerting them to the most current influenza situation and providing advice on prevention and control.

The Government launched the Influenza Vaccination Programme in November last year. So far more than 270,000 doses of flu vaccine have been administered to eligible target groups. The programme will last until March 31 and eligible people are urged to receive vaccinations as soon as possible.

Dr Chung reminded people to take the following measures to prevent influenza and other respiratory illnesses:
* Build up good body immunity by having a proper diet, regular exercise and adequate rest, reducing stress and avoiding smoking;
* Maintain good personal and environmental hygiene;
* Wash hands after sneezing, coughing or cleaning the nose;
* Maintain good ventilation; and
* Avoid visiting crowded places with poor ventilation.

People, particularly young children, elderly people and those with chronic diseases, should wear face masks and consult their doctors for medical advice promptly if they developed influenza-like symptoms.

Hong Kong: Eighteen persons with contact of dead birds put under medical surveillance (1/31/2009) [CHP]

Following the finding of dead birds in Sha Lo Wan, Lantau, the Centre for Health Protection (CHP) of the Department of Health is liaising with the Agriculture, Fisheries and Conservation Department in tracing people who had potential contact with the dead birds suspected of being infected with H5 avian influenza.


CHP contacted six members of the public who reported the incident and 12 staff involved in the operation of collecting dead birds.

Seventeen of them are asymptomatic and have been put under medical surveillance, a CHP spokesman said today (January 31).

The 26-year-old driver who had participated in collecting the dead birds on January 29 developed fever and symptoms of upper respiratory infection since January 27. He denied having contacted with the birds during the operation.

Given the fact that the driver developed symptoms two days before the operation, the spokesman noted that the chance of him being infected with avian flu was low.

''However, as a precautionary measure and in order to follow up his condition more closely, the driver has been admitted to the Princess Margaret Hospital for observation and further investigation,'' he added.

The spokesman reminded members of the public to remain vigilant against avian influenza infection and to observe the following measures:
* Avoid direct contact with poultry and birds or their droppings; if contacts have been made, they should wash hands thoroughly with soap and water;
* Poultry and eggs should be thoroughly cooked before eating;
* Wash hands frequently;
* Cover nose and mouth while sneezing or coughing, hold the spit with tissue and put it into covered dustbins;
* Avoid crowded places and contact with sick people with fever;
* Wear a mask when you have respiratory symptoms or need to take care of patients with fever; and
* When you have fever and influenza-like illnesses during a trip or when coming back to Hong Kong, you should consult doctors promptly and reveal your travel history.

Hong Kong: Carcasses of a goose and two ducks tested positive for H5 virus (1/31/2009) [AFCD]

Preliminary testing of a dead goose and two dead ducks found in Sha Lo Wan, Lantau has indicated a suspected case of H5 avian influenza, a spokesman for the Agriculture, Fisheries and Conservation Department (AFCD) said today (January 31), adding that further confirmatory tests were being conducted.


The carcasses of a goose and a duck were found and collected on January 29 at a beach near Sha Lo Wan football pitch.

They were highly decomposed when being found.

Today AFCD staff collected another dead duck at the same location. The spokesman said there were no poultry farms within three kilometres of where the carcasses were found.

This morning AFCD staff conducted inspection of the beach and the nearby villages of Sha Lo Wan Tsuen and Sha Lo Wan San Tsuen. There was no evidence of any backyard poultry being kept there.

AFCD is very concerned about the incident and will continue to monitor the situation. Inspections of the beach and its vicinity will be stepped up. The department is looking into different possibilities of why the goose and duck carcasses were found at the beach, including whether they had been washed ashore or dumped. The spokesman said a ban on backyard poultry has been in force since 2006. Unauthorised keeping of five kinds of poultry -chickens, ducks, geese, pigeons or quails ¡V is an offence with a maximum fine of $50,000. Repeat offenders are subject to a maximum fine of $100,000.

"The public can call 1823 Call Centre for follow up if they come across suspicious sick or dead birds, including carcasses of wild birds and poultry," the spokesman said.

The Centre for Health Protection of the Department of Health (DH) is contacting relevant parties and has put them under medical surveillance. People are advised to consult their doctors for medical advice promptly if they develop symptoms of influenza.

Members of the public are reminded to observe good personal hygiene. They should avoid personal contact with wild birds and live poultry and their droppings. They should clean their hands thoroughly after coming into contact with them. Poultry and eggs should be thoroughly cooked before consumption.

"In view of the case, the AFCD has phoned poultry farmers reminding them to strengthen precautionary and biosecurity measures against avian influenza. Pet bird shop owners, licence holders of pet poultry and racing pigeons have also been reminded to take proper precautions," the spokesman said.

The spokesman said that the department would conduct frequent inspections of poultry farms, the wholesale market and the Yuen Po Street Bird Garden to ensure that proper precautions against avian influenza had been implemented.

The department would continue its wild bird monitoring and surveillance.

The Food and Environmental Hygiene Department (FEHD) will continue to be vigilant over imported live poultry as well as live poultry stalls. It will also remind stall operators to maintain good hygiene. DH will enhance health education and distribute health advice leaflets.

AFCD, FEHD, the Customs and Excise Department and the Police will strive to deter the illegal import of poultry and birds into Hong Kong to minimise the risk of avian influenza outbreaks brought by imported poultry and birds that had not gone through inspection and quarantine.

The spokesman said the threat of avian influenza remained. The relevant departments will remain vigilant and continue to strictly implement preventive and control measures against avian influenza.

Dead H5 Confirmed Waterfowl in Hong Kong Raise Concerns
Recombinomics Commentary 20:16
January 31, 2009


Preliminary testing of a dead goose and two dead ducks found in Sha Lo Wan, Lantau has indicated a suspected case of H5 avian influenza, a spokesman for the Agriculture, Fisheries and Conservation Department (AFCD) said today (January 31), adding that further confirmatory tests were being conducted.

The carcasses of a goose and a duck were found and collected on January 29 at a beach near Sha Lo Wan football pitch.

Today AFCD staff collected another dead duck at the same location. The spokesman said there were no poultry farms within three kilometres of where the carcasses were found.

The above comments describe lab confirmed H5 in waterfowl in Hong Kong (see updated map). Dead waterfowl that are H5 positive are almost always H5N1 positive. The discovery of these three birds is cause for concern. They were found at a location which is adjacent to Hong Kong International Airport. Moreover, one of the drivers of the cullers has developed symptoms, which he had prior to collection of the birds, raising concerns that he is H1N1 positive, which is likely to be Tamiflu resistant, based on H1N1 circulating in Hong Kong at this time.

He was also likely to have been on prophylactic Tamiflu, as part of the culling team, raising concerns of an H1N1 / H5N1 dual infection leading to Tamiflu resistant H5N1.

More information on the status of the suspect case, and the sequence data of the H5 from the waterfowl, would be useful.

Hong Kong: Case of necrotizing fasciitis under investigation (2/2/2009) [CHP]

The Centre for Health Protection (CHP) of the Department of Health today (February 2) received a report of a necrotizing fasciitis case (flesh-eating disease) involving a 60-year-old man.


The man, living in Kwun Tong, injured his left middle finger when handling a crab on January 25. The finger later became swollen and he was admitted to United Christian Hospital on January 27.

He later underwent surgery and is currently in stable condition. Laboratory tests on pus from his left middle finger yielded Vibrio vulnificus, a type of bacteria causing necrotizing fasciitis.

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

People are reminded to adopt the following preventive measures:
* Avoid exposure of open wounds or broken skin to seawater or salty water;
* Wounds should be thoroughly cleansed and properly covered;
* Wear thick rubber gloves when handling raw shellfish.

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

Hong Kong: AFCD continues investigation into discovery of bird carcasses on Lantau (2/2/2009) [AFCD]

A spokesman for the Agriculture, Fisheries and Conservation Department (AFCD) said today (February 2) that following the H5 virus test results of a dead goose and two dead ducks last Saturday (January 31), nine more carcasses of birds were collected at Sha Lo Wan and Sham Wat Wan, Lantau between February 1 and 2 after a series of inspections around the area, adding that preliminary testing for the H5 virus is being arranged.

The government is very concerned about the incident and has launched a three-pronged investigation on the possible causes of the recent discovery of bird carcasses:

i)to step up inspections to ascertain whether illegal backyard poultry keeping is involved;

ii)to see if prevailing water currents and the weather are factors related to the discovery of the bird carcasses; and iii)to patrol along the waterfront to see if there are further findings of dead birds.

Of the carcasses found these two days, one dead goose was found in Sham Wat yesterday.

AFCD staff also collected a dead Cattle Egret and four dead chickens in Sha Lo Wan, as well as a dead chicken and two dead ducks in Sham Wat Wan today.

AFCD will continue to closely monitor the situation.

Checks have been strengthened against illegal keeping of backyard poultry throughout the territory.

The inspections in North Lantau are expected to complete in two days.

So far unauthorised keeping of poultry has not been observed in Sha Lo Wan and Sham Wat Wan.

The spokesman said that as a precautionary measure to reduce the risk of an avian influenza outbreak, a ban on backyard poultry keeping has been in force since 2006.

Unauthorised keeping of five kinds of poultry - chickens, ducks, geese, pigeons or quails - is an offence with a maximum fine of $50,000. Repeat offenders are subject to a maximum fine of $100,000.

"Apart from the increased inspections to strictly enforce the ban, leaflets will also be distributed during the inspections and publicity against backyard poultry keeping will be enhanced," the spokesman said.

"The public can call 1823 Call Centre for follow up if they come across suspicious sick or dead birds, including carcasses of wild birds and poultry," the spokesman added.

Members of the public are reminded to observe good personal hygiene.

They should avoid personal contact with wild birds and live poultry and their droppings. They should clean their hands thoroughly after coming into contact with them. Poultry and eggs should be thoroughly cooked before consumption.

Hong Kong: Latest avian influenza test results (2/5/2009) [AFCD]

Under the present surveillance programme on dead wild birds, preliminary testing of three bird carcasses collected in the past few days has indicated suspected cases of H5 avian influenza, a spokesman for the Agriculture, Fisheries and Conservation Department (AFCD) said today (February 5), adding that further confirmatory tests were being conducted.


The bird carcasses included a Grey Heron, a Peregrine Falcon and a chicken.

The spokesman said the dead Grey Heron was collected at Mai Po Nature Reserve on February 2.

There is a chicken farm within three kilometres of where the bird was found. AFCD has immediately dispatched staff to inspect the farm and found no abnormal mortality or symptoms of avian influenza among the chicken flocks. The farm will be put under enhanced surveillance.

"As a precautionary measure, the Mai Po Nature Reserve will be temporarily closed to visitors for 21 days starting tomorrow. We will monitor the situation closely and review the closure period as necessary," the spokesman said.

On February 3, AFCD staff collected the dead Peregrine Falcon near Long Beach Gardens, Ting Kau, Castle Peak Road, Tsuen Wan and the dead chicken in Butterfly Beach, Tuen Mun respectively. There were no poultry farms within three kilometers of where the two dead birds were found.

The spokesman said that two more dead chickens were found at Lung Kwu Tan, Tuen Mun today, adding that preliminary tests for the H5 virus will be arranged.

As regards the avian influenza test results of the 20 bird carcasses collected on Lantau from February 1 to February 4, preliminary testing showed that three chickens and two ducks were suspected of the H5 virus and further confirmatory tests were being conducted; a duck was confirmed to be H5N1 positive; seven birds tested negative for the H5 virus; and the test on the remaining seven birds is still going on.

Separately, AFCD staff collected a dead chicken and a dead duck in San Shek Wan today. Preliminary tests for the H5 virus are being arranged.

AFCD staff inspected 169 villages in Hong Kong today and found two live chickens illegally kept by a man in a household at Ng Ka Tsuen, Pat Heung. The man will be prosecuted under the Public Health (Animals and Birds) Ordinance for unauthorised keeping of poultry. During the inspection, one live chicken in San Uk Tsuen, Fanling and five live pigeons in Kam Sheung Road, Pat Heung were found unattended.

After taking samples for testing, AFCD has disposed of all the poultry.

The spokesman said a ban on backyard poultry has been in force since 2006. Unauthorised keeping of five kinds of poultry -chickens, ducks, geese, pigeons or quails '' is an offence with a maximum fine of $50,000. Repeat offenders are subject to a maximum fine of $100,000. All relevant government departments will continue to remain highly vigilant and strictly enforce preventive measures against avian influenza.

"The public can call 1823 Call Centre for follow up if they come across suspicious sick or dead birds, including carcasses of wild birds and poultry," the spokesman said.

The spokesman reminded the public to observe good personal hygiene and avoid contact with wild birds or live poultry.

Hong Kong: SFH on avian influenza (2/5/2009) [SFH]

Following is the transcript of remarks made by the Secretary for Food and Health, Dr York Chow, at a stand-up media session after attending Hospital Authority Spring Gathering 2009 today (February 5):


Reporter:
(inaudible)

Secretary for Food and Health:
It is very difficult to postulate where the three carcasses came from. But from the various investigations we have done, it is most likely drifting down from the Pearl River in the last week or two. Some of the new carcasses we have found are still under investigation. So far we have not found any extra H5 affected carcasses.
But as you know that we are doing wild bird and dead bird surveillance all the time. We test about 40 to 80 dead birds all over the territory every day. These include both those we have discovered in North Lantau and other areas. If we found any positive test results, we will announce right away. Every year we found some 10 to 20 such cases. As long as they are limited to wild birds, the risk to Hong Kong people is not that high because it has not been reported that wild birds can transmit the disease directly to human beings. It is usually through infection of poultry, and then the sick poultry would affect human beings.

Reporter:
(about the risk of avian influenza)

Secretary for Food and Health:
I don't think so because the whole region is still under the threat of avian flu, particularly during the whole winter. It is usually after May that the whole region starts to warm up, we will then see a decline of these incidents.

Reporter:
(about the H5N1 virus)

Secretary for Food and Health:
Let me talk about the virus samples we have collected so far. In the three carcasses which we have isolated the virus, the preliminary discovery is that it is related to a similar type of virus that happened in the southern part of China in the last two years, which is clade 2.3.2.
But it is slightly different from what we have discovered last year in our market and the outbreak in our local farm in December, which is clade 2.3.4.
But these are quite common clades of avian flu in the southern part of China and Hong Kong. It is certain that there is no significant mutation of the virus.
That is actually what we have discovered so far.
On the eight human infections of avian flu in the Mainland, we do not have the full report yet. But according to the preliminary information that is given to us, it is similar to the various virus that was isolated in northern China in the last one or two years.
So there is no significant epigenic mutation.
As far as the nature of the virus is concerned, we are confident that at this moment there is no evidence of human to human transmission and no significant epigenic change.

Reporter:
(inaudible)

Secretary for Food and Health:
What I have told you is that the virus has not changed that much. Whether the poultry and reaction to the virus, and whether the type of vaccine that is given to the various poultry in different parts of China might have slightly different response, these are something that we cannot conclude at this moment.

Reporter:
The threat of avian influenza is still there, right?

Secretary for Food and Health:
The threat is always there. We should always be vigilant against infectious diseases, particularly new diseases.For avian flu, the most important aspect is to prevent any people from approaching sick poultry or poultry from unknown source. This is the most important point I want to stress. If we can stay away from live poultry, particularly sick poultry or poultry from unknown source, I think we are pretty safe. I hope this will be the message you can tell all the citizens, particularly those who might have a habit of shopping in places where the poultry might come from unknown source, whether it is in Hong Kong or across the border. This is a very important message for them. (Please also refer to the Chinese portion of the transcript.)

Hong Kong: A case of dengue fever confirmed (2/6/2009) [CHP]

The Centre for Health Protection (CHP) of the Department of Health today (February 6) urged members of the public to guard against dengue fever following the laboratory confirmation of a case.


The case involved a 14-year-old boy who travelled to Indonesia with four relatives between January 21 and February 3. He developed fever, headache, muscle pain and rashes on January 29 and sought medical treatment in Indonesia the next day. He consulted private doctor upon returning to Hong Kong on February 3 and was admitted to Princess Margaret Hospital the same day. He is now in stable condition.

The CHP's investigation revealed that two of his travel companions had had fever while the rest are asymptomatic.

The CHP will continue to follow up the case.

This is the second case of dengue fever reported to the CHP this year. A total of 42 cases of dengue fever were reported in 2008. 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.

The latest information on dengue fever in other places can be found under "Travel Health News" on the Hong Kong Travel Health Service website at www.travelhealth.gov.hk/eindex.html .

"Though our analysis shows that the virus has no mutation for the time being and there is no sign of human-to-human transmission, we should not be off our guard against the disease.

''While the Government is highly vigilant and will continue to strictly enforce preventive measures against avian influenza, members of the public also have a role to play. The spokesman reminded members of the public to remain vigilant against avian influenza infection and to observe the following measures:

* Do not bring live poultry into Hong Kong;

Schools urged to boost flu precautions

Schools are urged to adopt precautionary measures against seasonal influenza as an increase in institutes reporting flu-like illness outbreaks is expected as Hong Kong has entered the flu season.

The Centre for Health Protection today announced 11 new institutional outbreaks affecting 51 people on its daily update, mostly involving schools.

During 2005-07 the highest number of institutional outbreaks reported every week during the flu season was between 10 and 32. In 2008 the highest weekly number of outbreaks was 106.

The centre anticipated the rise of reported outbreaks will persist over the next four to six weeks as Hong Kong stays in the influenza season.

An updated guideline with highlights on hygiene and infection control measures was sent to schools, kindergartens and childcare centres before the flu season.

School management have been briefed on the criteria of class suspension when there is a flu outbreak in their schools. They are also advised to keep parents properly informed about the latest situation.
