Contact-tracing of the 11 patients in the region will be conducted on Thursday, he said.

All the fresh COVID-19 patients from three districts had recently returned from other states and were in quarantine facilities, Jampa said.

Barring one, all of them are asymptomatic and have been admitted to various COVID Care Centres, he said.
