The 2008 bird flu outbreak in West Bengal was an occurrence of avian influenza in West Bengal, India which began in January 2008.[1] The infection was caused by the H5N1 subtype of the Influenza A virus and impacted at least thirteen districts, including Birbhum, Nadia, Murshidabad, Burdwan, Hooghly, Cooch Behar, Malda, Bankura, Purulia, Howrah, West Midnapore, South 24 Parganas and South Dinajpur. A range of precautions were instituted including a large cull of chickens, eggs, and poultry birds, the imposition of segregation zones, and a disinfection programme for the plant.[citation needed] The government put a blanket ban on the movement of poultry birds from West Bengal 5 February 2008, but repealed it a week later.[2]

The first outbreak in 2008 began in January, with confirmation from the World Organisation for Animal Health established through lab tests on 15 January 2008.[3] This outbreak continued through 31 October 2008.[4] A second outbreak began in Assam in November 2008, confirmed through lab tests on 27 November 2008.[5] This outbreak continued through 27 October 2009.[6] A third wave occurred from 15 January 2010 through 2 June 2010.[7] A fourth wave followed in Assam in February 2011, confirmed through lab tests on 16 February.[8] That outbreak did not reach West Bengal.[9] A fifth outbreak began in August 2011, once again in Assam, confirmed through lab tests on 8 September 2011.[10] and continued through 28 December 2011; the district of Nadia was affected.[11]
