16,000 ducks killed due to bird flu in Biddinghuizen, Netherlands

Bird Flu
A reassortant H5N6 avian flu virus detected in three Asian nations over the past few weeks has been confirmed in an outbreak in the Netherlands.
 
In other developments, South Korea—one of the countries that has already reported outbreaks from the H5N6 reassortant this season—reported another at a duck farm. And Cambodia reported an H5N1 avian flu outbreak in poultry, its first in nearly a year.
 
The outbreak in the Netherlands was first reported on Dec 8, and government officials had said initial tests from the duck farm near the city of Dronten was likely a highly pathogenic strain. In a notification yesterday from the World Organization for Animal Health (OIE), the country’s economic affairs ministry said the outbreak began on Dec 7 at a fattening-duck farm near the town of Biddinghuizen.
 
The virus killed 40 of 15,985 birds, and the surviving ducks were culled to curb the spread of the virus. Tests revealed the H5N6 subtype is a reassortment linked to H5N8 and not the Asian zoonotic H5N6.
 
Animal health authorities have established surveillance and protection zones around the farm. Screening at four farms in the 3-kilometer (km) surveillance zone was negative for H5N6.
 
A report from the country’s Wageningen Bioveterinary Research Institute, translated and posted by the infectious disease news blog Avian Flu Diary (AFD), said the farm was one of the first to be hit by H5N8 last season. The institute said initial tests suggest that it is not related to the zoonotic H5N6 strain. The virus’ H5 is related to the highly pathogenic H5N8 found in the Netherlands in 2016, and the N6 is related to low-pathogenic viruses previously found in wild birds in Europe.
 
The Netherlands is the fifth country to report the H5N6 reassortant, which is similar to a virus fist identified in Greece during last winter’s extensive H5N8 outbreaks that struck Europe and other parts of the world. The virus is a reassortant of highly pathogenic H5N8 and endemic Eurasian viruses.
 
In late November, South Korea reported its first outbreak involving the H5N6 reassortant, and the following day, Japan reported a detection in samples from a dead wild swan. A few days later, preliminary tests in Taiwan identified the same reassortant in a sample from a wild bird found dead in a national park.
 
In a related development, South Korea’s agriculture ministry today confirmed another H5N6 outbreak, this time at a commercial duck farm in the city of Yeongam in North Jeolla province, the country’s Yonhap News reported. The ministry said 76,000 ducks were slaughtered at five duck farms within a 3-km radius of the outbreak site to control the spread of the virus.
 
Officials said the virus is probably highly pathogenic, but more test results to further characterize it are expected.
 
Elsewhere, Cambodia’s agriculture ministry reported a highly pathogenic H5N1 outbreak at a local chicken farm in Kampong Chang province, according to a Dec 9 notice from the OIE.
 
The event began on Nov 22, killing nearly all of the 1,763 chickens at the location. The farm’s owner reported the sick and dead birds to provincial authorities on Nov 28. The surviving 24 birds were culled. So far the source of the virus isn’t known. Kampong Cham is in south central Cambodia.
 
The country’s previous H5N1 outbreak occurred in January.

66,500 chickens killed due to bird flu in Inner Mongolia, China

China’s Inner Mongolia region has culled 66,500 chickens following an outbreak of bird flu that has affected 35,000 birds, the Ministry of Agriculture said on Tuesday.
 
The H5N1 strain of the virus was confirmed at a hen farm in Tongliao city, which has of 3 million people, and has killed 15,000 birds, the ministry said in a statement on its website.
 
The outbreak is now under control, the ministry said.
 
The last bird flu outbreak in March killed 134 birds at a duck farm in central Hubei province.
 
The most recent case is the first confirmed major bird flu outbreak among poultry after winter months and brings the total culled since October to more than 240,000 birds.
 
Additionally, the H7N9 strain of the virus has caused at least 281 deaths since October in China.
 
Live poultry markets were shut down in many provinces following human infections, forcing egg producers to keep their hens beyond their prime time, as demand also plunged amid public fears over bird flu.
 
Flocks are particularly vulnerable to avian flu during the winter months and outbreaks usually die down afterwards.

5,000 chickens dead due to bird flu in Dawei, Myanmar

About 5,000 chickens have died of H5N1 bird flu, also known as avian influenza at a farm in Dawei, southern Tanintharyi region as of Friday, official media reported Saturday.
 
Sales of eggs and chickens are strictly prohibited in the affected area and cleansing measures in the farming area are being taken.
 
Other regions and states are also being examined after the avian flu’s outbreak in Dawei.
 
As the avian flu is usually classified into three groups, type A, B and C, Type A outbreak in Myanmar’s Tanintharyi region is the virus type which can easily infect both humans and animals.
 
The first outbreak of A/H5N1 avian flu occurred in 2006 in Myanmar.

25,000 birds dead due to bird flu in Kelantan, Malaysia

KUALA LUMPUR: Malaysia’s northeastern state of Kelantan on Wednesday (Mar 15) declared a disaster to fight the outbreak of H5N1 avian flu after the virus spread to two more districts – Pasir Putih and Bachok.
 
The highly pathogenic bird flu virus was first detected on Mar 6 after a few free-range chickens died outside the state capital Kota Bharu.
 
Eighteen villages in Kota Bharu have been affected and almost 25,000 birds – mainly chickens, ducks and geese – have been culled since the infection was reported.
 
The Kelantan Agriculture and Veterinary Services Department declared the outbreak a state disaster and ordered all agencies and departments to control the outbreak. 
 
The Malaysian Health Ministry’s director general, Noor Hisham, said no human infection has been detected so far but that the ministry is nevertheless on the alert. He added that the virus has not spread to other states, and that the outbreak seems to be contained in Kelantan, which borders Thailand.
 
The public has been told to take precautions, such as reporting to the authorities if they come into contact with dead birds, and to take care of their personal hygiene.
 
The state’s veterinary department believes that the virus could have been spread though infected fighting cocks, like in the last outbreak which occurred in 2004. State authorities have asked the community to avoid cockfighting activities for now.

MASSIVE deaths of chickens killed due to bird flu in Cao Bang, Vietnam

VIET NAM – Viet Nam reported outbreaks of avian flu H5N1 and H5N6 in northern Cao Bang province, the National Institute of Hygiene and Epidemiology (NIHE) said on Monday.
 
Accordingly, in 34 households in Quoc Toan community, Cao Bang’s Tra Linh district and one household in Cao Bang City’s Song Bang ward, massive deaths of chicken with unknown reason were recorded, the local Tien Phong (Pioneer) newspaper reported.
 
Local animal health officials took samples and sent them to the NIHE for tests. The test results showed that dead poultry in Tra Linh district were positive with avian influenza H5N1 while those in Cao Bang City were positive with H5N6 strain.
 
Cao Bang’s authorities have culled a total of 4,015 chicken and 18 doves as well as sterilized poultry cages and surrounding environment in two virus-hit areas.
 
The province has over 330 km of shared border with China, where avian influenza H7N9 virus is detected.

Nearly 6,000 birds killed due to bird flu in Southern Vietnam

Bird Flu
Nearly 6,000 chickens have been killed or culled after four months of no reported cases.
 
Two bird flu outbreaks among poultry have emerged in Vietnam’s central and southern regions, the animal health department said, warning the disease could spread to more areas.
 
Animal health officials culled around 2,800 birds after the H5N6 virus had been detected infecting the birds in the central province of Quang Ngai, the agriculture ministry-run department said in a statement posted Sunday. Quang Ngai is about three hours drive to the south of the popular tourist town of Hoi An.
 
Some 3,000 chickens infected by the H5N1 virus, another strain, have also been killed in the Mekong Delta province of Bac Lieu, the department said in another report. Bac Lieu is some 300 kilometers (190 miles) southwest of Ho Chi Minh City.
 
The outbreaks were the first reported in Vietnam four months after the country had successfully contained the disease in Ca Mau, Bac Lieu’s southwestern neighbor. A place is considered free of bird flu after 21 days without new infections.
 
Vietnam has reported no human infections of bird flu in the past two years.
 
The country is facing “very high” risks of bird flu spread in the coming time, the department said, warning about possibility that new virus strains could enter Vietnam due to the busy trade and smuggling activities in border areas. The virus often resurfaces in winter and spring.
 
Vietnam raised bird flu alerts last week as neighboring countries Cambodia and China reported ravaging outbreaks. The H7N9 bird flu virus, which was first detected in China in March 2013, has infected 340 people in China since January, 40 percent of whom have been killed.
 
In Vietnam the H5N1 strain has killed 65 people, one of the highest fatality rates in the world, since it recurred in 2003.
 
Health officials are urging the public to avoid consuming poultry with unknown origins and immediately seek help when they find sick or dead poultry.
 
Flu-like symptoms, such as fever, cough, chest pain or breathing difficulty should also be taken seriously.

Deadly Flu Virus Kills 79 Humans And Getting Worse In China

H7N9 Virus Alert
An avian influenza virus that emerged in 2013 is suddenly spreading widely in China, causing a sharp spike in human infections and deaths. Last month alone it sickened 192 people, killing 79, according to an announcement this week by China’s National Health and Family Planning Commission in Beijing.
 
The surge in human cases is cause for alarm, says Guan Yi, an expert in emerging viral diseases at the University of Hong Kong in China. “We are facing the largest pandemic threat in the last 100 years,” he says.
 
As of 16 January, the cumulative toll from H7N9 was 918 laboratory-confirmed human infections and 359 deaths, according to the World Health Organization (WHO). Despite its high mortality rate, H7N9 had gotten less attention of late than two other new strains—H5N8 and H5N6—that have spread swiftly, killing or forcing authorities to cull millions of poultry. But so far, H5N8 has apparently not infected people; H5N6 has caused 14 human infections and six deaths.
 
All human H7N9 cases have been traced to exposure to the virus in mainland China, primarily at live poultry markets. The strain likely resulted from a reshuffling of several avian influenza viruses circulating in domestic ducks and chickens, Guan’s group reported in 2013. Studies in ferrets and pigs have shown that H7N9 more easily infects mammals than H5N1, a strain that sparked pandemic fears a decade ago. There have been several clusters of H7N9 cases in which human-to-human transmission “cannot be ruled out,” but there is “no evidence of sustained human-to-human transmission,” according to an analysis of recent developments that WHO posted online last week. WHO’s analyses of viral samples so far “do not show evidence of any changes in known genetic markers of virulence or mammalian adaptation,” WHO’s China Representative Office in Beijing wrote in an email to Science.
 
Still, there are worrisome riddles. One is that H7N9 causes severe disease in people but only mild or even no symptoms in poultry. The only previous example of that pattern, Guan says, is the H1N1 strain responsible for the 1918 flu pandemic, which killed 50 million to 100 million people.
 
A menace again
 
After two quiet years, human cases of the H7N9 bird flu virus in mainland China spiked sharply at the end of last year, provoking renewed fears of an influenza pandemic.
Because poultry infected with H7N9 show few symptoms, the virus has spread stealthily, coming to the attention of authorities only after human victims appeared. Determining where the virus is circulating requires testing chickens and collecting environmental samples from live poultry markets.
 
Human infections have followed a consistent pattern, dropping to zero during summer, picking up in the fall, and peaking in January. During the fifth wave of H7N9 that began last fall, authorities noticed an early and sudden uptick in cases, with 114 human infections from September to December 2016, compared with 16 cases during the same months in 2015 and 31 in 2014, according to a surveillance report. The report notes that the virus has spread geographically, with 23 counties in seven eastern Chinese provinces reporting their first human cases last fall.
“It is too late to contain the virus in poultry,” Guan says. He predicts that the virus will continue to spread in China’s farms, possibly evolving into a strain that would be pathogenic for poultry. Authorities have culled more than 175,000 birds this winter to stamp out local outbreaks of H7N9 and other avian flu strains. Further spread of H7N9 “will naturally increase human infection cases,” Guan says. 
 
H7N9 may also spread beyond China’s borders, either through the poultry trade or through migratory birds. The virus has not been reported in poultry outside China. However, warns WHO’s Beijing office, “continued vigilance is needed.”
