#China | #HongKong – Oriental magpie robin tests positive for #H5N6 virus

The Agriculture, Fisheries and Conservation Department said today (May 5) that an oriental magpie robin found in Sai Kung was confirmed to be H5N6 positive after a series of laboratory tests.

The sick bird was found and collected near 10B Sha Kok Mei First Lane, Sai Kung, on April 29.

The AFCD will continue to conduct inspections of poultry farms to ensure that proper precautions against avian influenza have been implemented.

The spokesman reminded people to observe good personal hygiene. “They should avoid personal contact with wild birds or live poultry and clean their hands thoroughly after coming into contact with them,” he said.

#China | 20 additional confirmed cases of human infection with avian influenza #H7N9 – including 4 deaths

On 10 April 2015, the National Health and Family Planning Commission (NHFPC) of China notified WHO of 20 additional laboratory-confirmed cases of human infection with avian influenza A (H7N9) virus, including 4 deaths.

Onset dates ranged from 14 February to 21 March 2015. Cases ranged in age from 32 to 80 years with a mean age of 55 years. Of these 20 cases, 15 (75%) were male. The majority (18 cases, 90%) reported exposure to live poultry. One case is a health care worker, who had also poultry exposure. No clusters were reported. Cases were reported from five provinces: Anhui (3), Fujian (2), Guangdong (4), Shandong (1), and Zhejiang (10).

The Chinese Government has taken the following surveillance and control measures
  • Strengthen epidemiological and etiological monitoring and situation analysis;
  • Strengthen case management and medical treatment;
  • Provide information to the public and conduct risk communication with the public.

WHO is assessing the epidemiological situation and conducting further risk assessment based on the latest information. Overall, the public health risk from avian influenza A(H7N9) viruses has not changed. Comparing with the previous two months, the infection case number is decreasing and no new infected province has been reported. Further sporadic human cases of avian influenza A(H7N9) infection are expected in affected and possibly neighboring areas. Should human cases from affected areas travel internationally, their infection may be detected in another country during or after arrival. If this were to occur, community level spread is considered unlikely as the virus does not have the ability to transmit easily among humans.

WHO advice

WHO advises that travellers to countries with known outbreaks of avian influenza should avoid poultry farms, or contact with animals in live bird markets, or entering areas where poultry may be slaughtered, or contact with any surfaces that appear to be contaminated with faeces from poultry or other animals. Travellers should also wash their hands often with soap and water. Travellers should follow good food safety and good food hygiene practices.

WHO does not advise special screening at points of entry with regard to this event, nor does it currently recommend any travel or trade restrictions. As always, a diagnosis of infection with an avian influenza virus should be considered in individuals who develop severe acute respiratory symptoms while travelling or soon after returning from an area where avian influenza is a concern.

WHO encourages countries to continue strengthening influenza surveillance, including surveillance for severe acute respiratory infections (SARI) and to carefully review any unusual patterns, in order to ensure reporting of human infections under the IHR (2005), and continue national health preparedness actions.

#China | First case of #H5N6 virus found in wild bird in #HongKong

A spokesman for the Agriculture, Fisheries and Conservation Department (AFCD) said today (April 16) that the carcass of a peregrine falcon found at a construction site on Hung Yuen Road, Hung Shui Kiu, Yuen Long on April 9 was confirmed to be H5N6-positive after a series of laboratory tests.

It is the first case of H5N6 virus found in a wild bird in the territory. The AFCD will closely monitor the situation.

The AFCD will continue to conduct inspections of poultry farms to ensure that proper precautions against avian influenza have been implemented.

The spokesman reminded people to observe good personal hygiene. “They should avoid personal contact with wild birds or live poultry and clean their hands thoroughly after coming into contact with them,” he said.

China | 59 additional confirmed cases of infection with avian flu H7N9 including 17 deaths

On 9 March 2015, the National Health and Family Planning Commission (NHFPC) of China notified WHO of 59 additional laboratory-confirmed cases of human infection with avian influenza A(H7N9) virus, including 17 fatal cases. Onset dates ranged from 21 January to 25 February 2015.

Below is a breakdown of the 59 cases included in this notification by epidemiological week of symptom onset:

  • Week 4 (19 – 25 January) 5 cases
  • Week 5 (26 January – 1 February) 13 cases
  • Week 6 (2 – 8 February) 9 cases
  • Week 7 (9 – 15 February) 15 cases

Of these 59 cases, 44 (75%) were male. The majority (49 cases, 83%) reported exposure to live poultry or live poultry markets; the exposure history of six cases is unknown or unavailable. Three family clusters were reported, each comprised of two cases; four of the six cases had exposure to live poultry or live poultry markets, one case had no exposure to poultry, and one case is still under investigation. Cases were reported from nine provinces: Anhui (4), Fujian (1), Guangdong (35), Guizhou (1), Hunan (2), Jiangsu (3), Jiangxi (1), Shanghai (1), and Zhejiang (11).

The Chinese Government has taken the following surveillance and control measures

  • Strengthen epidemiological and etiological monitoring and situation analysis.
  • Strengthen case management and medical treatment.
  • Further strengthen measures like disinfection of commercial live poultry markets, closure of live poultry markets in places where infections occurred, and promotion of centralized slaughter and frozen products.
  • Provide information to the public.

WHO is monitoring the epidemiological situation and conducting further risk assessment based on the latest information.

Further sporadic human cases of avian influenza A(H7N9) infection are expected in affected and possibly neighbouring areas. Should human cases from affected areas travel internationally, their infection may be detected in another country during or after arrival. If this were to occur, community level spread is considered unlikely as the virus does not appear to have the ability to transmit easily among humans.

China | Hong Kong – Priority flu care for seniors as death toll rises to 228

The elderly may be given priority allocation of influenza vaccines when new supplies become available later this year.

Scientific Committee on Vaccine Preventable Diseases Chairman Dr Chow Chun-bong told reporters today the infection situation for seniors aged 85 and above is very serious, so giving them priority is being considered.

The committee will also analyse the infection figures in chronic disease patients to see which diseases bring a higher risk of flu complications, and may also give these patients priority in getting flu vaccinations.

He said the committee will make its recommendation when more information on the vaccine supply is available.

Centre for Health Protection Controller Dr Leung Ting-hung said the Government is forming a working group to implement the committee’s recommendations, and will discuss ways to boost vaccine coverage.

He also reported 22 new severe adult influenza cases were recorded from noon yesterday to noon today, including 18 deaths. It brings the total number of severe adult cases to 322, including 228 deaths.
