Total lockdown helped the Greater Chennai Corporation to ramp up testing and effectively detect symptomatic cases as most people stayed home, said Commissioner G. Prakash.
In a release, Mr. Prakash said: “The tracing of contacts during the lockdown was more effective and we did it swiftly.”
“Most of the COVID-19 patients were asymptomatic. Scores of persons who would have been earlier infected and in the incubating cycle, remained indoors and the spread from them was, to a great extent, avoided. Yes, lockdown has been a definite hit,” he added.
