At least 10 girl students of a government-run school have tested positive for coronavirus infection in Madhya Pradesh's Betul district, an official said on Saturday.

The local administration has decided to shut the school for a week after the infections were detected among Class 12 students.

Swab samples of 10 students from Government Girls Excellence School in Shahpur, about 36 km from the district headquarters, were collected for testing on January 13, school principal Virendra Namdeo said.

The reports of these students came out positive for the infection on Saturday, he said, adding that reports of 25 more students are awaited.
