New Delhi/ Mumbai | Jagran News Desk: Delhi and Maharashtra witnessed another spike in COVID-19 cases on Tuesday, sounding an alarm as several state governments and union territory (UT) administrations reimpose minor restrictions to avoid a fourth wave of the pandemic, which some experts have claimed will hit India in late May or early June.

Centre writes to states

With a slight rise in COVID-19 cases in India, Union Health Secretary Rajesh Bhushan on Tuesday wrote a letter to state governments of Haryana, Uttar Pradesh, Delhi, Maharashtra, and Mizoram, expressing concerns over the increasing positivity rate and fresh infections.

In his letter, Bhushan directed the state governments to 'strictly' keep a watch on rising cases and take pre-emptive action in areas witnessing a spike. He also asked states to ensure that people wear masks in crowded places.

"India has witnessed a sustained and significant decline in the number of COVID-19 cases over the past 2 months, with the country reporting less than 1000 daily new cases for the past few days. The weekly positivity rate has remained below 1 per cent. There are few states which are reporting a higher contribution to India’s daily new cases," he wrote.
