News Update February 19, 2014


Avian Influenza in Wild birds

Hong Kong (possible H7N9). Officials reported on February 17 that thirteen birds were found dead on the pavement in the Hong Kong region of New Territories. Photos in the local media suggest that all 13 were red-whiskered bulbuls. The birds are being examined to see if H7N9 was a factor in their deaths, although this virus is not known to be pathogenic to birds. This news comes after poultry markets on the mainland have been closed in Guangzhou and Shenzhen to prevent further spread of the virus. A spokesperson from the Hong Kong Bird Watching Society believes “there is no direct connection between the death of birds and H7N9. Red-whiskered bulbuls do not move among poultry or eat their food so there is little chance they would be affected with H7N9.” Lab results should be available within the next couple of days.

Avian Influenza in Poultry

Cambodia (HPAI H5N1). Cambodian health officials confirmed an outbreak of H5N1 in Kampong Champ province. Of 5,250 birds, 4,466 died while the remaining 784 were destroyed to prevent the disease from spreading.

Indonesia (HPAI H5N1). The head of Trenggalek Animal Health Center confirmed an outbreak of H5N1 after thousands of birds were found dead in the East Java province. The 20 samples that were tested were identical to the virus that had previously killed poultry in the area.

To date, about 30,777 birds have been culled to prevent the disease from spreading further. Additionally, Vietnam's Ministry of Agriculture and Rural Development (MARD) has banned all poultry sales both in and out of the country, is requesting that all live poultry markets be closed at least one day per month so the area can be sterilized, and is working on increasing people’s awareness of the deadly virus.

Avian Influenza in Humans

Canada (HPAI H5N1). The Alberta woman who died in early January after contracting the H5N1 virus may have caught it at an illegal live bird market.

Live bird markets, although illegal in Beijing since 2005, are customary and remain open throughout the municipality illegally. Chinese officials are testing the area around the former bird market to confirm the source of the infection.
