Four members of a family, who arrived here from Australia last week, tested positive for swine flu today.
Health Department officials said the persons, including three males aged 38, eight and six years and a three-year-old girl, tested positive for the flu in the medical tests of their swabs.
They would be administered with Tamiflu drugs after being quarantined in the Government Communicable Diseases Hospital (CDH) at Tondiarpet here, the officials said.
Meanwhile, four more suspected cases of the flu were reported in the city, officials said without revealing their identity other than confirming that they were all adults.
The persons found having symptoms such as cough have been quarantined at the CDH and their swabs sent for medical tests, officials said.
