The Chinese woman, who arrived at the pilgrimage site around 12.30 pm as a tourist, was diagnosed by a team of doctors and found to have no symptoms of coronavirus, such as fever, cough and breathing difficulty.
After the doctors screened her, she was sent back. She had plans to stay in Rameswaram and travel to Hong Kong on Tuesday, sources from the Department of Health Service said.
A mobile medical team comprising a doctor, a block health supervisor and a health inspector, was put in place at Rameswaram to monitor any such cases and render medical service, if required.
To check out suspicious symptoms of such infectious disease, an isolation ward was set up at Ramanathapuram Government Hospital.
