Chennai: Though fresh Covid-19 cases are steadily coming down in Tamilnadu, the presence of delta plus variants and new clusters have forced the health department to stay cautious particularly in the Chennai and Coimbatore regions and at least four districts around Thanjavur.
According to Health Secretary Dr J Radhakrishnan, some places like Chennai, with a positivity rate below one, are reporting new clusters. So, we are looking at a combination of epidemiological factors, he added.
On Tuesday, Chennai was back on top – overtaking Coimbatore – in the State’s daily number of coronavirus cases.
On 26 May , for the first time since the spread of Coronavirus in India in March 2020, Coimbatore surpassed Chennai in terms of the maximum number of daily new cases by reporting 4,268 cases while Chennai reported 3,561.
