SHANGHAI, May 6 (Reuters): Shanghai said on Friday that it has brought China's worst outbreak of Covid-19 under effective control, following a month-long lockdown of nearly 25 million people, with the authorities vowing to stand by their Covid Zero strategy despite mounting economic costs.
The number of new Covid-19 infections in China's financial hub had been on a "continuous downward trend" since April 22, the city's Vice-Mayor Wu Qing said.
