Ninety-one people at a high school in Shimane Prefecture have tested positive in recent days for the novel coronavirus in a cluster outbreak centered on the boys' soccer team, according to local authorities.

Of the total, 88 are members of the soccer team at the coeducational Rissho Shonan High School in the city of Matsue, and 82 of them live in the same dormitory. The team has played matches outside the prefecture since late July, fueling concerns about a wider spread of the virus.

The cluster of infections at the school, detected over the three-day holiday through Monday, raised the total number of novel coronavirus cases in Shimane Prefecture to 126.
