Health officials in Kerala have confirmed a bird flu outbreak at a government-run hatchery in Kollam district. The virus detected at the Thottathara layer birds hatchery in Ayur is a low-pathogenic H9N2 strain. Authorities emphasize this particular strain does not spread to humans and presents no immediate public health danger.
Laboratory Tests Rule Out Dangerous H5N1
Specialists at the National Institute of High Security Animal Diseases in Bhopal conducted detailed laboratory analysis. Their tests clearly identified the H9N2 virus. More importantly, they ruled out the presence of the highly pathogenic H5N1 strain. H5N1 is known for causing severe and widespread outbreaks in poultry populations.
Outbreak Timeline and Initial Response
The situation first came to light on January 2nd when workers reported the death of eight chickens at the facility. As deaths continued in the following days, the local animal husbandry department sprang into action. They collected samples from the affected birds and sent them for expert virological analysis.
The hatchery housed a substantial flock of 9,318 laying hens of various breeds. Officials traced the initial infection to Kaveri breed hens. These birds were brought to the farm from Hazargatta approximately one year ago.
Current Status and Containment Efforts
The total number of bird deaths has reached 1,283. However, officials report a positive development. The mortality rate has shown a noticeable decline since Sunday. This trend suggests that the outbreak is being successfully contained through swift intervention.
Despite the virus's mild nature, veterinary experts are not taking any chances. They have initiated postmortem examinations on recently deceased birds. The goal is to determine if any secondary infections or other health complications contributed to the fatalities. These examinations are being carried out under the strict supervision of the State Institute of Animal Diseases in Palode.
Wide-Ranging Surveillance Intensified
As a precautionary measure, authorities have significantly ramped up disease surveillance. Monitoring efforts now cover 16 panchayats surrounding the outbreak epicenter. The list includes Ilamad, where the hatchery is located, and numerous neighboring areas.
These areas are Ittiva, Idamulakkal, Kalluvathukkal, Ummannoor, Kadakkal, Veliyam, Velinalloor, Vettikkavala, Chadayamangalam, Nilamel, Pooyappally, Anchal, Alayamon, Madavoor, and Pallikkal. Notably, several of these regions share a border with Thiruvananthapuram district, highlighting the geographical spread of the vigilance operation.
Next Steps and Official Statement
District Animal Husbandry Officer Dr. D. Shinekumar provided clarity on the government's plan. He stated that final control measures for the outbreak will be decided at the state level. This ensures a coordinated and comprehensive response across Kerala.
The confirmation of a low-pathogenic strain, coupled with declining death rates, offers some reassurance. However, the intensified surveillance and planned state-level strategy demonstrate a committed effort to fully eradicate the virus and prevent any future spread.
