The minister conducted a review meeting on COVID control and prevention measures with Chengalpattu district officials amid rising COVID cases in the district.
Director of Medical Education Dr R Narayana Babu said that an 18-year-old girl with no comorbidities was tested positive for COVID-19 at a private hospital.
In his letter, he said there was no cause for panic or new restrictions, but urged officials to plan for the special mega vaccination camp on June 12.
Health and Family Welfare Secretary Dr J Radhakrishnan said that with COVID-19 cases on the decline, people have thrown caution to the wind and don't feel the need to get vaccinated.
Health Secretary J Radhakrishnan on Wednesday instructed all district collectors to ensure that the public observe COVID-appropriate behaviour.
On Sunday, 41,933 samples were tested for COVID, of which 95 returned positive, yielding a test positivity rate of 0.2 per cent.
Due to the poor patronage for Russian-made Covid vaccine Sputnik V, many private hospitals in Tamil Nadu haven’t been buying it for months now.
After the 19th mega vaccination camp, 89.06 per cent of people have received the first dose and 66.80 per cent received the second dose.
Apart from urging headmasters to conduct special camps to increase the coverage, authorities have also asked parents to take their children to nearby centres to get them the jabs.
Health Minister Ma Subramanian warned that the number of COVID cases in Tamil Nadu might rise further after the Pongal holidays as more than 8 lakh people from Chennai travelled to rural places.
Chengalpattu recorded 2,701, Tiruvallur 1,273, and Kancheepuram 831 cases on Sunday and they constitute 57.5 per cent of Tamil Nadu's cases.
He said that the analysis also showed that protective effect of vaccination 'is often scuttled by uncontrolled comorbidities', an issue that requires case-by-case analysis.
As of Wednesday, the daily cases grew to 28.47 lakh with the addition of 17,898 fresh infections while the toll climbed to 36,905 with 19 fatalities.
CM Stalin has asserted that the economy should not be affected, restricted lockdown enough for now, Subramanian said.
It was a feeling of déja vu for Chennaiites as lockdown returned on Jan 9, to contain the surge of Covid-19 cases.
