A Hokkaido man in his 70s has died after being infected with COVID-19, the local government said Sunday, bringing the domestic death toll to 12.

The Japanese national, who had no record of overseas travel, died Saturday after developing a fever and pneumonia on Feb. 23 while hospitalized, the regional government said. He had tested positive for the virus two days after developing pneumonia.

The government also announced that a nurse in her 20s and a man in his 40s were confirmed to be infected.

Hokkaido, which recently declared a state of emergency over the outbreak, has the largest number of coronavirus cases in the country. At least 72 infections have been confirmed in the region.

When making the emergency declaration on Friday, Hokkaido Gov. Naomichi Suzuki requested that people refrain from going out over the weekend.
