The official, whose identity was not disclosed by the state government, is currently undergoing treatment at a private nursing home here.
“His condition is stable and he is showing signs of recovery after being administered the swine flu antidote Tamiflu,” an official of the state health department said.
His samples were sent to the New Delhi based National Institute of Communicable Diseases(NICD).
Health department sources said the official could have been infected in London from where he returned last week.
The influenza A (H1N1) virus has infected more than 1,900 patients in the country and killed 25.
