China has reported the world’s first case of a human infected with the H10N3 bird flu, which is usually found in poultry. Health authorities said the risk of a large-scale outbreak is “extremely low.”
The patient is a 41-year-old man from Zhenjiang, a city in the eastern coastal Jiangsu province, China’s National Health Commission (NHC) announced on Tuesday. The man was originally hospitalized on April 28 after having fever and other symptoms.
“No human cases of H10N3 have been reported in the world, and the H10N3 virus among poultry is low pathogenic,” the NHC said, adding that the risk of large-scale spread of the infection among the human population is “extremely low.”
The NHC said the man became infected from poultry but did not provide any details regarding how it happened. The patient’s condition is stable, and he is ready to be discharged from the hospital, the health agency said.
H10N3 is a subtype of the avian influenza virus, which is lethal to wild birds and poultry, and can spread by air among animals through breathing just like the normal flu.
There are several strains of the bird flu of varying contagiousness that lead to sporadic outbreaks and usually affect poultry workers.
A major infection of humans by avian viruses in China was last observed during outbreaks of the H7N9 strain in 2013 and 2016-17. According to the UN’s Food and Agriculture Organization (FAO), 616 people have died from H7N9 since early 2013.

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.

Bulgarian veterinary authorities will cull 55,000 hens in the northern town of Slavyianovo after a bird flu outbreak was confirmed at a industrial farm there, the fourth since February 3, the food safety agency said late on Monday.
The agency said the four farms have been hit by highly pathogenic avian influenza type A, but did not disclose the strain of the disease.
The predominant strain in Europe at present is H5N8.
Some 160,000 ducks and 99,000 have been culled at three farms in Slavyianovo, some 190 km northeast of Sofia, this month as authorities try to contain the spread of the disease.

Maharashtra has been struggling with bird flu or avian influenza since more than a month. It has reported deaths of over 40,213 birds in the state since January 8 and has culled over 200,000 poultry birds following confirmation of bird flu from ICAR-National Institute of High-Security Animal Diseases (NIHSAD), Bhopal, till date. The figures include around 137,305 poultry birds in Navapur tehsil of Nandurbar district in the last two days (Sunday and Monday).
On Monday, 105,305 poultry birds were culled at four farms in Navapur to contain the spread.
The culling process is started only after receiving a confirmation of bird flu from ICAR-NIHSAD – the central laboratory for bird flu testing. The culling is being done within a one-km radius of the poultry farm affected by the virus.
This is the second time the state is dealing with bird flu in the last 15 years. In 2006, it was limited to Navapur, which was the epicentre of the disease in the Nandurbar district, but this time, the scenario is different. The zoonotic disease has spread to 45 epicentres covering 20 districts across the state.
However, 41 epicentres have been issued sanitisation certificates, indicating they are free from the virus and consumption of poultry products has been allowed in these areas. These epicentres will continue to be monitored for the next three months, government officials said.

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.

Around 190 pigeons were found dead in Ahmedabad city of Gujarat in over a period of two days, said officials on Thursday. Bird flu is been suspected as the probable cause of death in these pigeons.
Dr Rajendra Patel, assistant director, animal husbandry department, Ahmedabad district, said, to ascertain the exact cause of death of the pigeons in the Narol area, two carcass samples were sent to a Bhopal laboratory for testing for avian influenza.
“Around 190 pigeons were found dead in the Narol area of the city during the last two days in a suspected case of bird flu. We have discarded the carcasses as per protocols and sanitised the area.
“We have sent two samples to a Bhopal-based laboratory for confirmation (of bird flu),” said Patel.
Bird flu cases were first reported in Gujarat on January 8 when samples of some dead birds, found near a dam in Junagadh district, later tested positive for avian influenza.
Later, bird flu cases were also reported from Surat, Vadodara and Valsad districts, where samples of dead crows returned positive tests for the virus.
Bird flu is a highly infectious and severe respiratory disease in birds caused by the influenza virus.

Bird flu killed at least 750 pelicans found dead in Senegal’s Djoudj bird sanctuary, after authorities had initially ruled out the disease, scientific analysis has shown.
The birds – 740 juveniles and 10 adults – were discovered in the Djoudj national bird sanctuary on 23 January, and the country’s environment ministry said on Wednesday it had been closed to the public.
Now “we have the results of the analysis. It is indeed bird flu type A H5N1,” national parks director, Bocar Thiam, told Agence France-Presse.
The environment minister, Karim Sall, confirmed the bird flu diagnosis to RFM radio.
A mixture of wetlands, savannah, canals, marshes and lakes nestled in the Senegal river delta, Djoudj harbours more than 3m individual birds from almost 400 species.
Thiam had initially ruled out bird flu, claiming that it only affected birds that eat grains, rather than fish-eating birds like pelicans.
But the analysis by the ministry of livestock disproved that theory.
While the pelicans’ bodies and waste have been destroyed, parks chief Thiam said on Friday that “we’ll have to do more” to prevent the disease from spreading.
At the start of the year, Senegal culled more than 40,000 poultry after an outbreak of bird flu was detected on a farm in Thies in the west of the country.
Almost 60,000 birds had died in the preceding weeks, the livestock ministry said.
Authorities now believe that cluster has been stamped out.
Senegal’s borders have been closed to poultry products since a 2005 bird flu epidemic to prevent contaminations, but the government struggles to prevent illicit imports from neighbouring countries.
Several European countries are also suffering bird flu outbreaks, with 2m animals – mostly ducks – culled in France in December to try and keep it in check.

Japan has been hit by a major avian influenza outbreak, particularly in the west of the country. During the 2020/2021 season, since the first case confirmed in November 2020 at an egg-laying chicken farm in Mitoyo, Kagawa Prefecture, there have been a further 41 farms affected in 17 prefectures (as of February 2, 2021) with 7.1 million birds culled. This is a record high for a single season. Chicken farms have been most affected, including those for egg-laying birds and broilers for meat production, as well as those for raising chicks. On January 21, an outbreak was also confirmed at a farm producing duck meat in Chiba Prefecture.
A poultry farm where avian influenza was confirmed on February 2 was one of the largest in Ibaraki Prefecture and all 840,000 of its egg-laying hens were culled. This is the first time since 2006 that there has been an outbreak in Ibaraki.
According to livestock statistics from the Ministry of Agriculture, Forestry and Fisheries, Ibaraki is the prefecture with the highest number of egg-laying hens at 15.5 million, followed by Chiba with 12.4 million. Miyazaki has the highest number of broilers in the country with 28.2 million, while the neighboring prefecture of Kagoshima ranks second for broilers and third for egg-laying hens. The long-term spread of avian influenza in leading production areas has inevitably affected supply and demand of chicken and eggs.
The common factor in all the poultry avian influenza outbreak cases so far this season is the highly pathogenic avian influenza H5N8 virus with a high fatality rate detected each time. In 10 prefectures yet to experience farm outbreaks, the same virus has been found in wild birds and feces at and alongside rivers and lakes.
