History of Avian Influenza
As per the media note Avian Influenza (AI) viruses have been circulating worldwide for centuries with four known major outbreaks recorded in the last century. India notified the first outbreak of avian influenza in 2006. Infection in humans is not yet reported in India though the disease is zoonotic. There is no direct evidence that AI viruses can be transmitted to humans via the consumption of contaminated poultry products. Implementing management practices that incorporate bio security principles, personal hygiene, and cleaning and disinfection protocols, as well as cooking and processing standards, are effective means of controlling the spread of the AI viruses.
In India, the disease spreads mainly by migratory birds coming into India during winter months i.e. from September – October to February – March. Due to past experience regarding the reports of the disease in winter season, periodic advisories have been issued to all states/UTs before commencement of winter for keeping necessary vigil, enhancing surveillance, keeping strategic reserves of supplies (PPE kits, etc.), and preparedness to handle eventualities and IEC for public awareness.
Besides due to threat of global outbreak of AI, the Department of Animal Husbandry and Dairying (DAHD), Government of India had prepared an action plan in 2005 which was revised in 2006, 2012, 2015 and 2021 for guidance of State Government for prevention, control and containment of Avian Influenza in the Country, stated the note.
Here it is pertinent to mention that the last advisory issued to all states in the matter was on Oct 22, 2020, as mentioned in the note. Had states taken the advisory more seriously, the outbreak could have been averted.
