TPURAM: With summer advancing in Kerala, five persons were treated for sun stroke symptoms in Palakkad District where mercury soared to 41.5 degree celsius Wednesday.
The victims -- taxi drivers and vegetable venders -- were treated at a primary health centre at Pathiripala and sent home after first aid, officials said.
According to officials of Integrated Rural Technology Centre at Mutoor in Palakkad, average temperature in the district varied between 30 to 40 degree celsius during February-March.
Normally, Kerala experiences summer from the end of March but this year the heat has been intense since the last two weeks.
Water table in all the major rivers and dams in the state have started receding resulting in drinking water problems.
The water level had also come down in the famous tourist spot of Thekkady lake.
