CHENNAI: The number of new Covid-19 infections in Tamil Nadu has continued to rise with another 771 people testing positive in the past 24 hours.
The state directorate of public health (DPH) has attributed the sudden surge in Covid cases to
sub-variants. For instance, the percentage of BA.5 cases had rapidly increased from 4% in May to 25.2% in June 2022. However, BA.2.38 continued to be the predominant variant in May and June (35%), according to DPH data.
Among the 771 new cases reported on Wednesday, almost three-fourths of the cases were from Chennai (345) and its neighbouring districts of Chengalpet (126), Thiruvallur (32) and Kancheepuram (18). This has forced the government to introduce stricter Covid protocols here.
For instance, Kancheepuram district collector has barred commercial establishments from switching on air-conditioners and wedding halls were told to accommodate only up to 100 people. Others have almost doubled the number of people tested this week as they have started collecting samples from those who were in contact with the infected.
TN overall screened more than 20,000 samples and the Test Positivity Rate (TPR) has jumped to 4.4%. Given the spread has started in a few other districts, the total number of active cases in the state has also gone up to 4,678.
However, less than 5% among them need hospitalisation. The rest with mild symptoms are in home isolation. Health authorities are monitoring their status by conducting saturation tests, health minister Ma Subramanian told reporters on Wednesday.
“Getting vaccinated is as important as following protocols now. More than 1.5 crore are due for their first and second doses and the forthcoming mega vaccination camp on July 10 across the state will focus on administering vaccine to them,” he said. There was no change in TN’s Covid death toll.
