A 24-year-old man was admitted to a hospital in Chennai on Saturday with suspected symptoms of swine flu on his arrival from Singapore.
The youth, who arrived along with his family members at the airport here last night, was suffering from cough and fever following which he was quarantined.
A special team of doctors attended on him and he was sent to the Government Communicable Diseases Hospital (CDH) in Chennai, where he has been quarantined this morning, airport officials said.
Earlier this week, a couple who was admitted to the CDH had tested positive for the virus. An eight-year-old boy in Madurai, who complained of fever, cough and sore throat on return from New Jersey, had also tested positive for the A(H1N1) influenza.
