[India has reported, since its 1st outbreak in January 2006, a total of 86 H5N1 outbreaks in domestic poultry; the 1st 7 outbreaks, in 2006, were located in the midwestern state Maharashtra. All the other outbreaks since then were located in the far northeastern parts of India, peaking in 2008 (70 outbreaks). There were 5 outbreaks in 2010 and, so far, 3 in 2011.
For the location of Dhuburi in India's northeastern state of Assam, between Bangladesh, Bhutan, and Nepal, go to the HealthMap/ProMED-mail interactive map at http://healthmap.org/r/1d-p.
