Gorakhpur poultry shops shut for 21 days after bird flu cases
Representative image GORAKHPUR: All poultry shops in Gorakhpur in Uttar Pradesh were asked on Saturday to shut for 21 days following detection of avian influenza strains, H5N1 and H9N2, in bird samples from five localities in the city. Samples were taken at Jhungia Bazar, Aluminium Factory area, Taramandal, Bhagat Chauraha, and Shaheed Ashfaqullah Khan Zoological Park. These were sent to the National Institute of High Security Animal Diseases (NIHSAD) at Bhopal in MP, which confirmed the presence of both strains of the virus. The chief veterinary officer (CVO) activated district-level Rapid Response Teams and set up a control room at the Sadar Veterinary Hospital to handle the outbreak. Following the confirmation, additional municipal commissioner, Nirankar Singh, said as per central govt guidelines, culling operations have begun within a 1km radius of the infected zones. All live birds within this zone will be culled and disinfection drives are underway there. The CVO appealed to the public not to heed to rumours and to cooperate with the administration. A total of 1,328 samples from Gorakhpur and 1,470 samples from the Gorakhpur-Basti division were tested during the surveillance exercise. The bird flu started from Gorakhpur zoo where four animals - a lion on April 30, leopard Mona on May 8, tigress Shakti on May 7, and a wolf - have so far succumbed to the virus. The zoo has already been shut for containment measures.

First bird flu death in Andhra Pradesh of same clade as first death in Haryana
Visakhapatnam: An analysis of the specimen from the recent fatal bird flu case in Palnadu district by the National Institute of Virology in Pune has revealed that the two-year-old girl, who succumbed to H5N1 infection, was infected with the clade 2.3.2.1a strain. The investigation further clustered the case with a 2024 travel-associated case from West Bengal. The death of the two-year-old girl from Narasaraopet was the second human death from H5N1 bird flu virus in India. Notably, India's first bird flu death in Haryana in 2021 was also linked to the same hemagglutinin gene clade, 2.3.2.1a, where a young boy fell victim to the illness. The observed clustering in the Palnadu case indicates that migratory wild birds or other cross-border transmission routes may be facilitating the spread of this lineage, highlighting an intricate network of viral evolution in the region. NIV-Pune has shared details of the Palnadu case with GISAID (Global Initiative on Sharing All Influenza Data), which monitors influenza virus evolution, transmission patterns, and genomic surveillance worldwide. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Addis Ababa: AI guru Andrew Ng recommends: Read These 5 Books And Turn Your Life Aroun... Blinkist: Andrew Ng's Reading List Undo Including the Palnadu case, India has so far reported a total of five human avian influenza cases involving H5N1 and H9N2. These include one case from Maharashtra in June 2019, one from Haryana in July 2021, and two from West Bengal in April and May 2024. In Andhra Pradesh, the recent infection marks the state's first human bird flu case and death. According to the phylogenetic tree dataset available on GISAID — which compiles genetic sequence records from influenza virus samples collected across various countries and hosts — the clustering observed in the Palnadu case strongly suggests cross-border or migratory bird transmission. The dataset features sequences from diverse geographical locations such as Bangladesh, Cambodia, Vietnam, and Australia, reinforcing concerns about the global movement of the virus. For instance, several entries in the dataset from domestic avian hosts such as ducks and chickens appear alongside isolates from wild birds, crows, and even non-avian hosts like tigers. This variety in host species not only points to the adaptability of the virus but also elevates its potential for interspecies transmission, posing an increased zoonotic risk not just in Andhra Pradesh, but nationwide. According to GISAID, limited surveillance of this lineage in India underscores the urgent need for expanded monitoring in poultry and wild birds to assess its spread, evolution, and zoonotic risk. Andhra Pradesh has recorded eight outbreaks of bird flu across the state in 2025, affecting more than 5.4 lakh birds and leaving 6.02 lakh birds susceptible. These outbreaks, which occurred in regions ranging from West Godavari, East Godavari, and Krishna in coastal Andhra Pradesh to Kurnool in Rayalaseema, took place in both large-scale commercial farms and small backyard settings. While some outbreaks began in mid-January, others were not detected until mid-February. According to experts, this staggered chronology suggests that the virus possibly spread from an initial focal point before seeding new areas through bird movement or lapses in biosecurity, highlighting significant challenges in controlling avian influenza outbreaks.

Two-year-old girl dies from bird flu after eating raw chicken
A two-year-old girl in southern India died from bird flu after eating raw chicken, the first fatality linked to the H5N1 strain since 2021. The toddler, from Palnadu district in Andhra Pradesh state, died on 15 March after developing fever, breathing difficulties and diarrhoea. Authorities said the child contracted the virus after consuming raw chicken. It was not clear if she had been deliberately fed the meat or accidentally eaten it. She was initially admitted to a local health centre but taken to a city hospital on 4 March after her condition deteriorated. A sample test for avian influenza of H5N1 strain at the hospital returned positive, and the patient eventually died despite receiving appropriate medical treatment, the hospital said in a statement. Damodar Naidu, director of animal husbandry in Andhra Pradesh, said the child was admitted to hospital two-three days after consuming the raw chicken, according to Down To Earth. Following the death, he said authorities conducted physical surveillance of all poultry farms in the region, but found no signs of bird flu among poultry. 'There were isolated outbreaks in February but effective control measures were implemented promptly,' Mr Naidu said. 'No traces of the virus were found in the surveyed areas.' However, he urged the public to consume only properly cooked chicken and eggs. 'Poultry should be cooked to at least 70C. Eggs should be boiled and not eaten raw,' he said. No one in the girl's family tested positive for the flu. The federal health ministry deployed an outbreak response team to Andhra Pradesh to assist in the case. Bird flu is caused by a virus that infects birds and sometimes foxes, otters and seals. It rarely infects humans, but a major strain known as H5N1 has caused global health concern. Only five cases of H5N1 and H9N2 strains have been detected in India over the past five years, the Andhra government reported in a statement. An 11-year-old in the northern Haryana state died in the last confirmed human fatality from H5N1 in 2021. The boy died after developing multiorgan dysfunction. According to the WHO, the first human outbreak of the virus took place in 1997 in Hong Kong. There have been a little more than 900 known cases globally since 2003 with nearly 50 per cent proving fatal. in an area where the disease had been confirmed in captive birds. Last year, the strain spread rapidly in dairy cow herds in the US and the US Centres for Disease Control described it as an "ongoing multi-state outbreak".

What to Know About the H5N9 Bird Flu
Credit - Getty Images In late January, scientists at the World Organization for Animal Health (WOAH) reported the first cases of H5N9 avian influenza in the U.S., on a duck farm in California. The latest strain isn't a surprise, say public-health experts, since influenza takes different forms in different species and is constantly mutating. But the appearance of H5N9 is still concerning, especially in light of the ongoing outbreaks in chickens and cows of H5N1. Here's what to know. 'We've never seen a global spread of avian influenza virus like this,' says Michael Osterholm, director of the Center for Infectious Disease Research and Policy at the University of Minnesota. 'We've seen an explosion in the number of outbreaks in poultry and duck operations over the course of recent weeks. This reflects the fact that there is so much H5N1 in migrating waterfowl." There are about 40 million migratory aquatic waterfowl in North America, Osterholm says—which means there are plenty of potential bird-flu hosts, whose poop spreads disease. Read More: Scientists Are Starting to Track Bird Flu in Farm Wastewater "What we are seeing more and more are outbreaks in poultry operations because this virus is common in the environment and it's blowing around," he says. "That's different from anything we've seen before.' H5N9 is 'not commonly seen in poultry in general,' says Eman Anis, assistant professor at the University of Pennsylvania School of Veterinary Medicine. (Anis is part of a lab that conducts national testing of poultry samples for avian influenza.) The virus is the result of a combination of H5N1, H7N9, and H9N2, according to researchers in China who studied samples isolated from bird markets in 2015. At the time, the scientists said it wasn't clear how adept the virus was at infecting people—which remains the case today—but warned it was "imperative to assess the risk of emergence of this novel reassortant virus with potential transmissibility to public health." When H5N9 was recently detected in ducks, H5N1 was detected along with it. That's concerning, since viruses are able to combine and reassemble their genetic material. With so much H5N1 circulating, the danger of that strain coming into contact with other avian viruses—like H5N9—increases the chances that new, mutant strains can emerge. The fear is that one of those reassortments could result in a strain that easily infects and spreads among people.

'When you take risks, sometimes you get lucky. I always say you can close your eyes and cross a busy street, and you might not get hit by a car. But that doesn't mean it's a good idea." "What absolutely needs to be happening right now is we need a global coordinated strategy," Jha says. "Migratory waterfowl do not observe national boundaries, and any surveillance for [avian influenza] has to be done in a multi-national way.' President Trump's decision to withdraw the U.S. from the World Health Organization (WHO), and his instructions for federal employees not to work with anyone from the global health agency, will make such a coordinated effort nearly impossible, Jha says—and that it will heighten the chances that viruses, including bird flu, cause larger outbreaks.
