Even as the Tripura Government was fighting bird flu menace, the fresh outbreak of the disease was reported from Sidhai Mohanpur area, about 25 km from here. The area falls under the Indo-Bangladesh border and incidents of death of chickens and a few other birds were being reported from the area. However, official confirmation of the dreaded avian disease was still awaited though sources in the Animal Husbandry Department have found the presence of H5N1 virus in the blood samples of the sick birds.
