"The boy, who was admitted in a critical condition seven days back at BC Roy Hospital in Beliaghata, died early this morning. He stopped responding to treatment and was put on ventilation," Principal Secretary (Health and Family Welfare) Moloy Dey told PTI.
The boy was suffering from high fever for a few weeks and was brought to BC Roy Hospital only when the private hospital failed to treat him, Dey said.
So far, 47 people have been infected by the H1V1 virus in the state though nobody is critical, he said.
The state government has created a ward specially meant for swine flu patients at BC Roy Hospital.
