NEW DELHI, Aug 14 (Reuters) - India is intensifying preparations to deal with avian influenza as it borders countries with "uncontrolled outbreaks" in poultry and is also close to nations with human cases, its top health official said.

Federal Health Secretary Naresh Dayal referred to Myanmar and Bangladesh -- which have seen several outbreaks in poultry this year and share a long border with India"e;s remote northeast.

"We are surrounded by countries with uncontrolled outbreaks in poultry and birds," Dayal told Reuters in an interview on Tuesday. "And further, there is Vietnam and Indonesia."

Indonesia and Vietnam -- both within a couple of hours flying distance from some Indian cities -- have reported human deaths from bird flu this year.

Indonesia says it has 83 confirmed bird flu deaths since 2003, the highest for any nation.

"Worldwide, human-to-human transmission is feared. We have to be able to tackle that if, God forbid, it starts," Dayal said.

Globally, there have been more than 300 confirmed human cases of bird flu since 2003 due to the H5N1 strain and nearly 200 deaths, according to the World Health Organisation.

The H5N1 virus remains mainly a disease affecting birds, but experts worry it may mutate into a form easily transmitted from person to person.

SELF-INTEREST

India this month managed to contain an outbreak of bird flu in chickens in its remote Manipur state bordering Myanmar, which had two flare-ups in poultry in July alone.

India has stepped up vigil on its borders with Myanmar as well as Bangladesh, said Dayal, adding that New Delhi had offered to help its two neighbours fight the disease.

"We are willing to provide help to Bangladesh. It is also in our own interest," he said, adding India was also ready to help Myanmar fight the virus if requested.

New Delhi has reported no human case from its three major outbreaks in poultry since 2006, but health officials are worried about its northeast region, which also borders China, where 16 human deaths have been reported since 2003.

Authorities are increasing the number of laboratories that can test for bird flu in humans.

Besides the three existing facilities, New Delhi will set up a new laboratory in the northeastern state of Assam as well as the eastern city of Kolkata, Dayal said.

India has an emergency stock of 900,000 anti-viral Tamiflu tablets and has prevented its sale at retail outlets to ensure no one self-medicates and develops resistance to the drug.

Dayal said more "regional response teams" were being trained to react quickly to deal with any suspected human cases, a crucial need in a densely populated country where the state medical infrastructure is overstretched and of poor quality.

"We will have to react fast but there is no need for panic," he said.
