As India battles the second Covid wave, Maharashtra, the worst-hit state in the country, saw the highest-ever daily surge with 57,074 fresh infections on Sunday.

Delhi also recorded a huge spike of 4,000 fresh infections taking the Covid tally to 6.76,414 infections. This is the highest daily surge this year. It was one of the top five states that reported the highest number of cases in the last 24 hours.
Chhattisgarh (5,250), Karnataka (4,553) and Uttar Pradesh (4,136) are the other three states that saw the biggest spike in cases in the last 24 hours, the government data shows.

The surge in cases comes ahead of polling in four states - Assam, Bengal, Tamil Nadu and Kerala - and Pondicherry, a union territory. The Election Commission has ensured Covid protocols are strictly followed at polling booths.
