Bengaluru: Karnataka confirmed a record 2228 new covid-19 cases that takes its total to 31,105 cases of which 17,782 are active.The surge was driven by its growth capital, Bengaluru, that broke its own record of highest single day spike as 1373 persons tested positive in the 24 hours until 5 pm on Thursday, according to the daily bulletin of the state health department.The number of fatalities rose to 490 as 17 more people died on Thursday.The surge in cases has put the B.S.Yediyurappa-led state government on the backfoot as it continues to rely on the success it achieved during the three months of covid-19 induced lockdown.Not just has the case count in Bengaluru gone up, but around 50 persons with travel history to India's technology.
