New Delhi, Feb. 19:
A day after the outbreak of bird flu in the country, the Union government remains clueless about how the infection reached Nandurbar district of Maharashtra. "We have not yet established how the bird flu reached Nandurbar. Migratory birds are believed to spread the infection, but there is no evidence of this," said animal husbandry joint secretary Upma Chawdhry. Migratory birds fly to the country from China and Central Asia during winter to escape the extreme cold in those regions.
"Our information is that there are no water bodies (believed to be frequented by migratory birds) in Nandurbar. So it?s surprising how migratory birds could have spread the infection there," pointed out animal husbandry commissioner S.K. Bandhopadhyay. "We may also check for signs of any illegal import of birds by traders in the region. Import of poultry from outside the country was banned two years ago," said Mr Bandhopadhyay. "We will check for signs of any illegal import of vaccines for the poultry. We will also explore whether any wild birds in the region could have picked up the flu from migratory birds," he added.
Health ministry officials say that "the role of migratory birds in the spread of the highly pathogenic avian influenza is not fully understood". But officials say "considerable circumstantial evidence suggests that migratory birds can introduce low pathogenic H5 and H7 viruses to poultry flocks, following which the virus mutates to a highly pathogenic form", resulting in the deaths of lakhs of poultry and creating the danger of the infection spreading to human beings as well.
"We propose to conduct an epidemiological study of the Nandurbar region after the process of culling of birds is over," revealed Mr Bandhopadhyay. The epidemiological study will comprise both geographic and human studies in the region as well as disease patterns. "Only then can something be conclusively stated," the animal husbandry commissioner said.
