As many as 25 medical teams have been constituted which would visit various parts of the state.
"Each team would prepare a comprehensive, comparative report on flu-prone and non flu-prone regions, helping identify the basic principles behind the transmission of the virus, such as interplay of humidity, rainfall and low temperature," said Dinkar Raval, Deputy Director (Epidemics) and the state nodal officer for swine flu.
Of the 65 persons who died of swine flu this year, Raval said, 25 per cent were pregnant women, 15 per cent were diabetics and 10 per cent were patients with major chest illnesses.
"The team will also study whether doctors are aware of the latest modalities of the treatment," he said.
