However, what has the state health department worried is that these cases continue to occur, despite the sweltering heat, in which the virus is believed to become dormant or less active at the least.
The department has now sent samples to the National Institute of Virology (NIV), Pune and hoping to find the answers.
"We do not exactly know the reason why the virus is still active in the hot climate. Last week, we have sent samples for laboratory testing to NIV, Pune. We will be able to comment once the report comes," Dr Aditya Atreya, incharge, Integrated Disease Surveillance Programme (IDSP) said.
The health department had sent a total of 810 samples for laboratory testing and found 228 found confirmed H1N1 virus positive.
