Over 85 people have tested positive for the disease in the premises of the Governor's residence. Is it all bad news? Not really. The Chief Minister, during his meeting with officials Wednesday, said aggressive testing, contact tracing and effective treatment was helping the state fight the pandemic. Palaniswami told officials the fatality rate in Tamil Nadu has dropped to 1.6 per cent, which he claimed was the lowest in the country. He also said the recovery rate had risen to 73 per cent with more than one lakh people recovering from the disease so far. Tamil Nadu has tested the most number of samples for Covid-19 in the country at nearly 25 lakh. And, therefore, the more tests conducted, the higher the detection of cases. The state has now begun using the antigen tests, which provide results within half an hour. What's the situation like in Chennai? Palaniswami on Wednesday said Chennai numbers were on gradual decline. There are 97,575 people infected in the city so far. Meanwhile, Chennai crossed a grim milestone on Wednesday, reporting over 2,000 deaths due to Covid-19. With 2,076 deaths so far, Chennai has a fatality rate of 2.1 per cent. The recovery rate, on the other hand, is 84.5 per cent.
