Nineteen Indian passengers tested positive for COVID-19 in a recent flight from New Delhi to the Chinese city of Wuhan under the Vande Bharat Mission (VBM), even as India on Monday announced plans to operate four more such flights to China beginning November 13.

The October 30 Air India flight, the sixth operated by India to China in recent months and the first to Wuhan where the virus emerged in December last year, brought 277 Indians from New Delhi and evacuated 157 on its return under India''s mega mission to evacuate stranded Indians from abroad.
