Four of the people are being kept for observation in a hospital in the western state of Maharashtra.
The state's minister for animal husbandry says 50,000 birds have died in the past few days at a poultry farm in Nandurbar, north of Bombay.
In Vienna, Austrian officials say the H5N1 virus is spreading in the country with the discovery of a dead swan in the city and other birds in the countryside.
