Kerala reported more than half of the total COVID-19 cases recorded in the country in the previous seven days, according to the central government on Tuesday.
An official said at a joint press conference on the pandemic that 37 districts across nine states, including Kerala (11 districts) and Tamil Nadu (seven districts), had seen an increase in daily new COVID-19 cases over the last two weeks.
According to the official, 44 districts across 11 states and union territories reported a weekly positivity rate of more than 10%.
Kerala accounted for 51.51 percent of all COVID-19 cases reported in India in the previous seven days, he said.
The reproduction number, which indicates the spread of COVID-19, was greater than one in five states, according to the central government: Himachal Pradesh, Punjab, Gujarat, Madhya Pradesh, and Uttar Pradesh.
Although there has been a stabilisation in COVID-19 cases in the country, the increasing trend of reproduction number in some states is cause for concern, it said, adding that there are significant reasons to enforce pandemic control measures.
As of August 9, the government reported that the Delta Plus variant of SARS-CoV-2 had been detected in 86 samples across India, including 34 in Maharashtra.
According to Union Health Ministry data updated on Tuesday, India recorded 28,204 new coronavirus infections, the fewest in 147 days, bringing the total number of cases to 3,19,98,158, while active cases fell to 3,88,508, the fewest in 139 days.
