Decentralisation of vegetable trading, intensive fever camps and high number of COVID testing were among the intensive measures taken to contain the spread of the virus in the district.

“We have never decreased the number of persons subjected for COVID-19 testing right from April. An average of 2,000 samples were lifted per day. Based on the results, we mounted vigil over the primary and secondary contacts of those who tested positive to check whether they were infected. The line departments worked in tandem to subject the primary and secondary contacts to rule out the infection,” Mr. Sivarasu said.
