However, the woman's eight-year-old daughter who travelled along with her mother is tested negative for swine flu. But all three have been put in quarantine at isolated facility in Coimbatore and have been administered with Tamiflu.
Speaking to media, health secretary, Naresh Dayal said, "The family was checked for fever both in US and Chennai and they had tested negative. They started getting symptoms only after they reached Coimbatore."
India is trying to track down other 55 domestic passengers who travelled with the family on the Kingfisher flight IT-2901 from Chennai to Coimbatore. They are also advised to check for the symptoms at the earliest, before it becomes a full fledged outbreak.
The family who tested positive reported to health facility after the boy had fever. The health ministry said, "The patients are presently afebrile (have no fever). All their local contacts have been traced. They too are afebrile and their health status is being monitored. Passengers of the Kingfisher flight and those of EK-542 are being traced and advised to monitor their health status."
