TOKYO, April 7 (CNN) -- Japanese Prime Minister Shinzo Abe formally declared a one-month state of emergency just now at a task force meeting.

The state of emergency will last from today through May 6, and be in place across seven virus-hit prefectures, including Tokyo.

Abe had announced yesterday that he would make the declaration today, as the country sees increasing spikes in cases.

Under the declaration, "basic economic activity" will still continue, with public transport and supermarkets remaining open. People are urged to stay at home and not make unnecessary trips.
