India's southern state of Kerala on Thursday announced a two-day lockdown as federal authorities planned to send experts to fight the spread of infections in the country's leading COVID-19 hotspot.
India's daily cases have fallen after a devastating second wave that overwhelmed the healthcare system, and vaccination efforts are gaining steam. But experts have warned the authorities against swiftly reopening cities.
Kerala, with an active case load of around 154,000, accounts for 37.1% of India's total active cases. Its case positivity rate indicating the pace of spread in infections is now the country's highest.
"Special intensified stringent restrictions are being implemented in the areas where the test positivity rate is high," the state's department of disaster management said in a statement announcing a "complete lockdown" from Sunday.
During the last four weeks, seven of Kerala's 14 districts reported an increasing trend in daily new infections, government data released earlier this week showed.
On Thursday, the federal government said it was sending half a dozen experts to monitor Kerala's worst-hit areas and work with state authorities on strategies to contain the outbreak.
India's central government has left decisions on lockdowns and reopenings to local state authorities, leading to an uneven response that experts say has allowed new hotspots to develop even as infections fall in previous epicentres.
India on Thursday reported 43,509 new coronavirus cases in the previous 24 hours, taking the overall tally to 31.53 million, though experts believe the actual figure could be much higher.
It is second only to the United States in the number of cumulative infections.
The western state of Maharashtra, India's industrial hub, was the second-most affected in the country, accounting for over 20% of the overall cases, official data showed.
Maharashtra, the state hit hardest by a devastating second wave of infections, began lifting lockdown restricts last month to revive the economy.
The reproduction rate, or R value, of COVID-19 in India hit 1 on July 24 for the first time since May when daily infections were near a peak of 400,000, raising the risk of an even faster spread of infections.
"The increase (in R value) is expected as we are opening up the country," Bhramar Mukherjee, a professor of epidemiology at the University of Michigan, wrote in a tweet.
"Where it goes from here depends on the public and the policymakers."
