Japan expanded its Coronavirus state of emergency on Wednesday for a second week in a row, adding eight more prefectures as a surge in infections fuelled by the Delta variant strains the country’s health care system.

The government last week extended the state of emergency until September 12 and expanded the areas covered to 13 prefectures from six including Tokyo. With four new prefectures added to a separate “quasi-emergency” status, 33 of Japan’s 47 prefectures are now under some type of emergency measures. Eight prefectures were upgraded from quasi-emergency status to a full emergency.
