Even as the Union Health Ministry seems to be searching for an explanation behind the sudden spurt in the incidence of the disease, official data said that the total number of cases of swine flu reported till Feb. 12 this year has reached 6,298.
After the ministry reported 216 deaths due to swine flu in the first 10 days of February -- which had put the toll between Jan. 1 and Feb. 10 at 407 -- it today said that the number of casualties till Feb. 12 stands at 485.
"This year, there have been 6,298 cumulative cases while there have been 485 deaths from January 1 to February 12," said Arun Panda, additional secretary, Health ministry.
As per the data, Rajasthan has seen the maximum 130 deaths due to swine flu while 1,631 cases have been reported in the state till Feb. 12. In Gujarat, in the same period, 117 people have died of swine flu with the state reporting 1,233 cases.
Fifty-six people died in Madhya Pradesh, which reported 192 cases, while there have been 51 casualties in Maharashtra out of the 352 cases which came to light there till Feb. 12.
"The incidence (of swine flu) and deaths happen during this time of the year. It does not happen in May, June or even March. It is inversely proportional to the ambient temperature. Once the temperature shoots up, the incidence comes down.
"There is no explanation and reason behind this spurt... The virus is the same H1N1 strain since 2009. There has been no mutation.
