Thailand shut down a large market complex in Bangkok after it emerged as a new cluster of Covid-19 cases, prompting authorities to ramp up testing and order vaccination for those at high risk of infection.

The Bang Khae Market compound, which houses six markets selling everything from fresh vegetables to raw meats and cooked food, will remain closed for three days after Tuesday’s cleaning and disinfection, the Bangkok Metropolitan Administration said. The Thai capital reported 100 new infections on Tuesday, majority of which came from active case finding efforts to curb the spread, officials said.
