New Delhi, Mar 31 (IANS): Twenty-six athletes of the National Centre of Excellence in Patiala have tested positive for Covid-19, the Sports Authority of India (SAI) said on Wednesday.

"Of the 313 tests conducted in Patiala, 26 people have tested positive while out of the 428 tests conducted in Bengaluru, four have been found positive for virus," the SAI said in the statement.

"Those who have tested positive are being isolated in the residential facilities within the campus. The campus has been sanitised and all precautionary measures are being taken to ensure complete safety of athletes," it said.

As a precautionary measure, the SAI also conducted Covid-19 RT-PCR tests for Olympic Games-bound athletes, coaches, and support staff. According to SAI, the reports received on Wednesday indicate that all Olympic-bound athletes in Patiala and Bengaluru have tested negative.

Patiala is the main hub of track and field athletes. Besides a core group of 400 metres sprinters and throwers, top boxers and weightlifters train at the National Institute of Sports (NIS).
