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 Tuesday night.
