The review by the team led to the conclusion that a delay in treatment and a large floating population in the state are some of the main reasons behind the deaths, a state health official said.

'The team observed that both Pune and Bangalore, which have recorded a large number of swine flu related deaths, have shown same kind of death patterns. Firstly, the climate of both the cities is almost similar. Both the cities have large numbers of floating population too,' Karnataka's Principal Secretary (Health and Family Welfare) I.R. Perrumal told IANS in Bangalore.

Of Wednesday's 214 fresh cases, 69 were reported from Tamil Nadu. The other states from where fresh cases were reported were Delhi (36), Karnataka (35), Maharashtra (28), Haryana (19), Andhra Pradesh (11) and Uttarakhand (5).

Health authorities in Delhi said most of those who have been affected with the virus are children. Of the 36 fresh cases, 20 are children.

'The situation is under control and the government is doing its best efforts in providing treatment to H1N1 patients,' Delhi Health Minister Kiran Walia said.
