The Nigeria Centre for Disease Control (NCDC) reports an outbreak of highly pathogenic avian influenza (HPAI) H5N1 in poultry on 30 farms from seven states in Nigeria.
The affected states include Kano, Plateau, Bauchi, Gombe, Nasarawa, Kaduna and the Niger States.
In addition the European Centre for Disease Prevention and Control (ECDC) reports:
As of 28 March 2021, 83 human nasopharyngeal/oropharyngeal samples have been collected from contacts of confirmed birds in four states: Kano (27), Bauchi (19), Gombe (19), and Plateau (18). All contacts were farmers, farmworkers, bird-handlers, and traders, and all were asymptomatic. Of the 83 collected samples, 64 samples were analyzed using real-time RT-PCR (rRT-PCR). From the 64 analyzed samples, seven were positive for influenza A virus, including six samples of influenza A(H5) neuraminidase (NA) remains undetermined) and one sample of unsubtypable influenza A virus. These seven confirmed samples have been reported in Kano (four) and Plateau (three) states and have been shipped to the WHO Collaborating Centre in the US for further characterization.

Vietnam has culled more 100,000 poultry so far this year in a bid to contain the spread of bird flu in the Southeast Asian country, the government said on Monday.
The country has reported outbreaks of the highly pathogenic H5N1 and H5N6 bird flu strains in 14 provinces, the government said in a statement on its website.
“The risk for the outbreaks to spread on a larger scale is very high,” the statement said.
Vietnam has a poultry flock of around 460 million birds, and small-scale bird flu outbreaks have occurred sporadically in the country during the past few years.

New cases of avian influenza believed to be of a highly pathogenic strain have been confirmed at poultry farms in both Chiba and Miyazaki prefectures, their prefectural governments announced on Sunday.
Chiba Prefecture decided to cull all of some 1.15 million chickens raised at the affected farm in the town of Tako to prevent the spread of the virus and requested the dispatch of the Self-Defense Forces for help to complete task swiftly.
This is the seventh bird flu outbreak at a farm in Chiba since December last year, following an outbreak confirmed at a farm in the nearby city of Asahi only on Saturday.
Meanwhile, the 11th farm bird flu case in Miyazaki this season hit a poultry facility in the town of Shintomi. The prefectural government is culling all of around 240,000 chickens raised there. The facility is located only about 500 meters away from a farm where the viral outbreak occurred in late January.
Restrictions have been imposed on the transfers of eggs and chickens from all farms within 10 kilometers of the facilities newly hit by the disease in the two prefectures.

Avian influenza outbreaks continue to ravage the poultry sector in France, leading to the culling of over a million birds in the southwest region.
Since the first case was detected in mid-November, the number of outbreaks has increased to 264.
In a statement released on Friday, the Food and Agriculture Ministry said as a preventive measure 1.116 million poultry, mostly ducks, have been culled in the municipalities of Gers, Landes, Pyrenees-Atlantiques and Hautes-Pyrenees.
Around 12 cases have been recorded outside the south-west region.
The highly contagious H5N8 virus was also found to have spread among wildlife. Authorities recorded at least 10 deaths among wild birds due to the virus.
To control the risk of spreading the virus, the movement of poultry has been prohibited in these areas.
The H5N8 virus exclusively affects birds and is not transmissible to humans through the consumption of meat or eggs.

Russian authorities have reported 7 poultry farm workers aged 29 to 60 years infected with the A(H5N8) strain of avian influenza, also known as bird flu. This is the first reported detection of this strain of avian influenza in humans. The human infections occurred on a poultry farm in Astrakhan, Russian Federation, and were reported to WHO by Russian health officials via channels of the International Health Regulations (2005).
Concerns were raised when 101 000 out of 900 000 egg-laying hens on the farm died in early December 2020. An investigation by Russian veterinary public-health authorities detected avian influenza A(H5N8), which was then confirmed by the World Organisation for Animal Health (OIE) Reference Laboratory and the Federal Centre for Animal Health in the city of Vladimir, Russian Federation.
Follow-up tests on the 7 workers from the poultry farm suggested recent infection with the virus, though they showed no symptoms. There was no clinical evidence of onward transmission to families or close associates of the workers. Further information on serology among contacts of the positive cases is required to fully assess the risk.
Dr Richard Pebody, who leads the High Threat Pathogen Team at WHO/Europe, was quick to reassure: “The people who were reported to be infected did not develop symptoms and they were all exposed to an infected poultry flock in the course of their work. The infection does not appear to have come from other human beings – which is good news.”
Dr Pebody added, “The poultry flock has been culled and no further infections in humans have been found. It is also encouraging that this incident shows the system that alerts local and international authorities is working. However, this underlines the ongoing importance of global surveillance in the face of constantly evolving influenza viruses. Changes to the influenza virus must be closely monitored in animals and humans alike; this is a good example of the One Health approach, recognizing that human and animal health are intertwined and depend on each other.”
Based on available information, the risk of human-to-human transmission remains low and WHO recommendations have not changed as a result of the incident. When avian influenza is circulating in an area, farms and contact with live animals, for example in markets, should be avoided. Precautions must be taken by those working with poultry.
WHO is now following up with public health authorities in the Russian Federation and other relevant organizations. Although this strain of influenza has not previously been known to affect humans, it has been detected in farmed and wild birds in countries across the European Region, including Bulgaria, Czechia, Germany, Hungary, Kazakhstan, the Netherlands, Poland, Romania and now the Russian Federation.

Around 30,000 birds on a poultry farm in Northern Ireland have been culled following the detection of bird flu
Around 30,000 birds on a poultry farm in Northern Ireland have been culled following the detection of bird flu at the premises.
This marks the first time the disease has been confirmed in a commercial flock in the country since 1998. A 3-mile protection zone has been set up around the farm near Clough in County Antrim by the Department of Agriculture. Northern Ireland’s Chief Veterinary Officer (CVO) Dr Robert Huey has initiated disease control measures based on clinical signs and the initial results provided by the Agri-Food and Biosciences Institute (AFBI) as well as the recent detections of highly pathogenic Avian Influenza H5N8 in a number of wild birds across Northern Ireland (NI).
Dr Huey said: “The department was contacted on New Year’s Eve by a Private Veterinary Practitioner (PVP) reporting suspicion of notifiable avian disease at a holding in County Antrim. Since then, we have taken samples and initial results from AFBI suggest that notifiable Avian Influenza (AI) is present. We are now awaiting official confirmation from the National Reference Laboratory to determine pathogenicity and strain of the disease.” He continues: “Given the level of suspicion and the density of the poultry population around the holding, it is vital that as a matter of precaution, we act now and act fast. I have therefore taken the decision to cull the birds as well as introduce temporary control zones around the holding in an effort to protect our poultry industry and stop the spread of the virus.” An epidemiological investigation is underway to determine the likely source of infection and determine the risk of disease spread.

South Korea said Wednesday it is speeding up efforts to cull poultry around farms infected with highly pathogenic bird flu amid growing concerns over the virus spreading nationwide.
The country has culled 5.59 million birds as preventive measures since reporting the first farm-related case in late November, according to the Ministry of Agriculture, Food and Rural Affairs.
Chickens accounted for 3.5 million, followed by quails with 1.2 million and ducks with 880,000.
Local authorities slaughtered poultry within a 3-kilometer radius of infected farms.
South Korea has reported 16 cases of highly pathogenic bird flu from farms. South Jeolla Province accounted for six, and Gyeonggi and North Jeolla provinces accounted for three infections each.
There were also cases from the provinces of South and North Chungcheong, along with South Gyeongsang.
Highly pathogenic avian influenza is contagious and can cause severe illness and even death in poultry.
The country reported this year’s first highly pathogenic avian influenza case from wild birds in late October. Since then, a total of 29 cases have been found from wild bird habitats nationwide.
Authorities are currently investigating seven suspected cases from wild birds.
