【明報專訊】Yesterday (1 May) Shanghai reported 7,872 cases of COVID-19 infection, marking the fourth consecutive day with less than 10,000 cases. Six districts, which account for 60% of the city's population, have basically achieved zero COVID ''society-wise'', meaning that citizens in these districts can move freely within the area. If things continue along this trajectory for one or two more weeks, it can be expected that the situation in Shanghai will fully return to normal.
