Several types of avian flu viruses are not creating concern in India as they are in Eurasian countries and North America, Dr Robert G Webster, a World Health Organisation (WHO) expert, said here today.
Dr Webster was delivering the Foundation Day lecture ofthe Department of Biotechnology, Government of India, hosted by the Rajiv Gandhi Centre for Biotechnology (RGCB) here, on the topic 'Pandemic and Avian Influenza: the Need for Surveillance in India', a release said.
"But that aspect cannot be interpreted as Indians are notbeing susceptible to bird flu viruses because these viruses are constantly mating and re assorting to create newer strains. Some of these viruses may attain the capability for a human-to-human infection which can be lethal," explained the virologist.
Other than H1N1, highly pathogenic subtypes like H5N1 and H7N9 can spread across the borders since in neighbouring China new viruses and avian flu are constantly evolving, which creates a major concern. Wild birds are crossing the Himalayas to spread the flu in India like the H5N1 attack, he said.
