Prime Minister Narendra Modi on Wednesday expressed concern over a rise in COVID-19 cases in parts of the country and called for "quick and decisive" steps to check the "emerging second peak".

In a virtual interaction with the chief ministers of different states over the pandemic situation and the ongoing vaccination drive, Modi said in states like Maharashtra, Punjab and Madhya Pradesh the number of COVID cases has seen a rise while nearly 70 districts in the country have seen an increase in the positivity rate by over 150 per cent of late.

"If we do not stop it here, then a condition for a nationwide outbreak may emerge," he said and called for quick and decisive steps to stop it, reported PTI.

The confidence brought by India's fight against the pandemic so far should not cause carelessness, he said, and asked chief ministers to take measures, including more testing, enforcement of preventive measures as well as increase in number of vaccination centres to curb the virus.

People should not be put on panic-mode but need to ensure that they get rid of this problem as well, he said.

"Test, track and treat" should be taken as seriously now as it has been for over a year since the outbreak, he added.

The Prime Minister reiterated that RT PCR tests should make up for over 70 per cent of overall Coronavirus testing, while noting that states likes Chhattisgarh, Uttar Pradesh, Kerala and Odisha have been mostly dependent on antigen tests, the report said.

Modi also spoke against the wastage of vaccines and called for more vaccination centers.
