SHANGHAI (Reuters) - Shanghai will ask all of its 26 million residents to take another round of tests for COVID-19, a city official said on Monday, adding that lockdown curbs will continue until the exercise is complete.

Some residents will be asked to take nucleic acid tests, while the rest will be asked to self-test using antigen tests, city officials said at a news conference.
