Bird Flu Outbreak: Nagpur Zoos Restrict Entry Amid H5N1 Scare

A recent highly pathogenic avian influenza (HPAI), or bird flu, outbreak has been confirmed at the Central Hatchery at Seminary Hills in Nagpur, Maharashtra, sparking immediate concern and precautionary measures among local animal facilities. The outbreak, detected on March 24, 2026, led to the deaths of approximately 800 to 1,000 birds, with subsequent laboratory tests by the Bhopal-based CSIR-National Institute of High Security Animal Diseases (NIHSAD) confirming the presence of the avian influenza virus. In response to this localized outbreak, zoos and animal rescue centers within Nagpur have swiftly implemented stringent biosecurity protocols to safeguard their captive animal populations. The Gorewada Rescue Centre and Balasaheb Thackeray Gorewada International Zoo have restricted entry to all individuals except essential caretakers and veterinarians near animal and bird enclosures. Furthermore, these facilities have ceased feeding chicken and eggs to animals and are conducting continuous health monitoring of all residents. The Transit Treatment Centre (TTC) at Seminary Hills, situated within a two-kilometer radius of the outbreak site, has taken extra precautions, including shifting all birds to an isolation ward and strictly limiting access to these areas. Maharajbagh Zoo is also undertaking similar disinfection processes and special care to protect its animals. This localized incident in Nagpur is not an isolated event but part of a broader, ongoing challenge with H5N1 avian influenza across India in early 2026. Multiple states have reported outbreaks, necessitating extensive containment and surveillance efforts. In January 2026, Kerala experienced a re-emergence of the H5N1 virus in poultry, impacting numerous farms and resulting in the culling of approximately 84,400 birds to curb further spread. Stricter hygiene and biosecurity measures were consequently enforced in Kerala and neighboring Tamil Nadu. Tamil Nadu faced its own significant H5N1 alarm in late January and early February 2026, with over 1,000 to 1,500 crows found dead in and around Chennai. Samples from these wild birds tested positive for the H5N1 virus, prompting statewide surveillance and rapid testing initiatives. Similarly, Bihar reported H5N1 infections in dead crows across several districts, including Darbhanga and Bhagalpur, and later in poultry in Patna. This led to the establishment of surveillance alert zones and culling operations for affected poultry farms. Chhattisgarh also confirmed an H5N1 outbreak at a state-run poultry farm in Bilaspur in March 2026, which resulted in the deaths of 4,400 chickens. Authorities responded by intensifying surveillance within a 10-kilometer radius of the affected farm. Andhra Pradesh likewise grappled with a widespread outbreak affecting around 500,000 chickens in early 2026, leading to extensive culling and movement restrictions to control the viral spread. The Nagpur region has a history of avian influenza incidents. In February 2025, an H5N1 outbreak at the Gorewada Rescue Centre resulted in the tragic deaths of a captive tiger and two leopards. This severe incident prompted the Central Zoo Authority (CZA) to issue a nationwide circular advising all zoos across India to enhance their preparedness and adhere to the National Action Plan for 'Prevention, Control and Containment of H5N1'. Earlier, in February 2025, poultry samples from Bada Tajbagh in Nagpur had also tested positive for H5N1. Despite the widespread presence of the H5N1 virus in avian populations and isolated incidents in mammals, it is crucial to note that as of early 2026, India has reported zero confirmed human cases of H5N1 avian influenza in connection with these ongoing outbreaks. Globally, human infections with H5N1 remain uncommon, but when they do occur, they can be severe. The general public's risk is considered low, however, individuals with close or prolonged contact with infected birds, other animals, or contaminated environments face a higher risk. Public health advisories emphasize maintaining strict hygiene, avoiding contact with sick or dead birds, and ensuring poultry and eggs are thoroughly cooked to mitigate any potential risk.
