Arignar Anna Zoological Park in Vandalur will remain closed on October 22 and 23 after H5N1 Avian Influenza was confirmed in seven water birds by the National Institute of High Security Animal Diseases (NIHSAD), Bhopal, on October 21. The birds, including four painted storks, a grey pelican, a grey heron and an oriental darter, died between October 3 and 7.

The zoo had cordoned off the area and taken preventive measures, including disinfection and biosecurity protocols, after the first death, but remained open until the test results arrived. No further bird deaths have been reported since October 9. Zoo director Ritto Cyriac told TOI the outbreak is likely over.
As per central protocol, visitor entry must stop immediately upon confirmation of H5N1. The zoo urged public cooperation. Sampling must be repeated every 15 days at least four times, the zoo may reopen after two consecutive negative results are cleared by the competent authority.
Both The Hindu and TOI report the same core facts: NIHSAD confirmed H5N1 in seven water birds, and the zoo is closed on October 22 to 23 for sanitisation. The Hindu provides a detailed account of the Centre's post-confirmation protocols, including repeated sampling and the exemption of endangered birds from culling. TOI emphasises the human-interest angle, quoting zoo director Ritto Cyriac saying the outbreak is likely over and noting that 40 birds died at Guindy Children's Park seven months ago. Neither outlet adopts a critical or pro-government stance, the coverage is uniform, straight news reporting. The differences are purely in depth and emphasis, not in slant. The next concrete step is the mandated fortnightly sampling, the zoo can only reopen after two consecutive negative results.
