India cities see sharp fall in Covid cases

India's capital Delhi and financial hub Mumbai have reported a big fall in Covid-19 infections in the past two days and most of those who contracted the virus have recovered at home, authorities said yesterday.

Mumbai's daily new infections fell below 10,000 on Sunday for the first time since early this month, after touching an all-time high of 20,971 on January 7. It reported 7,895 infections late on Sunday, Mumbai's municipal corporation said.

Delhi's cases have fallen consistently since hitting a peak of 28,867 on January 13 and was expected to be fewer than 15,000 yesterday, for the first time since early January, the city government's health minister told reporters.

Both cities have said more than 80% of their Covid-19 hospital beds have remained unoccupied since the fast-transmitting Omicron variant led to a massive surge in cases from the start of the year.

"With very large numbers of sub-clinical, asymptomatic and undetected cases, it is difficult to pinpoint a peak by new cases," Rajib Dasgupta, head of the Centre of Social Medicine & Community Health at New Delhi's Jawaharlal Nehru University, said in an email.

"In this situation, monitoring hospitalisation is more prudent; today's case can be next week's hospitalisation."

Other epidemiologists say a national peak in cases could come by early- or mid-February.

Experts have attributed the low hospitalisations to high levels of previous infections and vaccination. India has fully vaccinated about 70% of its 939 million adults and hopes to give the primary two doses to another 70 million by next month.
