Shanghai reported the fewest new COVID-19 cases in a week for Wednesday, with all infected people already in government-run quarantine, a sign the financial hub may avoid tighter restrictions as the outbreak comes under control.

The city recorded 47 infections for Wednesday, down from 55 on Tuesday. While daily cases have jumped from single digits last week, they are no longer rising precipitously.

Still, concern Shanghai could be headed for another citywide lockdown — with a number of apartment blocks and neighborhoods already subject to movement restrictions — remains. That angst was fueled Monday by two neighborhood committees issuing an open letter calling on residents to stockpile enough food and medical supplies to last 14 days, according to reports carried in media outlets including eastday.com Tuesday night.

Speculation a wide-ranging lockdown is coming coursed through China’s social media platforms earlier in the week, spurring the government to say the claims were false and "pure rumors” on its official WeChat account. Some online claimed that a phased lockdown, akin to the first stage of Shanghai’s move in March, could be imposed once high school entrance exams slated for this week had been completed. The anxiety mirrored concerns in Beijing in May, when online rumors of a lockdown there saw residents flocking to grocery stores and hoarding food.

Even as the rest of the world moves to live alongside the virus, lockdowns remain commonplace in China, which continues to stick to a policy of keeping out the virus with stringent curbs. The "COVID zero" strategy is leaving the country isolated as travel barriers fall elsewhere, and is impacting the world’s second-largest economy, with lockdowns and restrictions affecting the operations of traders to manufacturers. But President Xi Jinping remains undeterred, doubling down on the policy in an address last month.

Shanghai’s spike in infections after weeks of few cases comes after the detection of the more contagious BA.5 sub-strain of the omicron variant. Nine of the city’s 16 districts are currently undergoing mass testing in response, along with other areas where cases have been found.

While denying rumors of an imminent lockdown, officials said the directive to stockpile food and medicines was aimed at "stimulating people’s epidemic prevention awareness,” according to the reports.

Shanghai’s flareup is just one of the resurgent outbreaks China is currently grappling with.

Lanzhou, the capital of Gansu province in northwestern China, shifted into a full lockdown Wednesday with its more than 4 million residents ordered to stay in their homes. One person from each household is allowed to go out once a day for essentials. Wugang, a steel and iron-making city of some 300,000 inhabitants in Henan Province, announced a lockdown on Tuesday after finding a single Covid case.

Zhuhai, which neighbors Macau, has shut all kindergartens and entertainment venues in the Xiangzhou district after a cluster emerged at a kindergarten, infecting 35 people as of July 13. Some compounds in the district have also been locked down and residents ordered to stay at home.

As of Monday, some 30 million people across China were under some form of movement restrictions to quell transmission, but authorities have so far steered clear of strict lockdowns in key economic regions.
