A total of 14 deaths have been reported from the state since January 1 till Friday, of which Ahmedabad Municipal Corporation (AMC) and Rajkot Municipal Corporation (RMC) recorded four deaths each.
State health officials have attributed this sudden rise in the cases to the cold weather.
“We are seeing a rise in the number of cases this month but it is a phenomenon being reported in other states as well, like Rajasthan. There is a certain level of peaking around August (monsoon) and in winter months, especially January, aided by the cold and cloudy weather which often leads to the manifestation of this (H1N1) virus,” Health Commissioner Dr Jayanti Ravi.
According to official data, Ahmedabad and Rajkot have been reporting high incidence of the flu.
As many as 17 cases were reported in AMC area, two in RMC area and one each in Bhavnagar, Vadodara, Surat and Gandhinagar, on Friday itself.
