Pune, May 12: Two passengers, who arrived from Spain and the USA respectively, have been kept under observation at a hospital in Pune since they were suspected to be patients of swine flu.
Presently the suspected patients have been quarantined in the isolation ward of Naidu Hospital in Pune.

Till that time they will be treated with antibiotics and other drugs.

If the reports come negative they'll be sent out immediately," said Dr N B Kadam, physician-specialist, Naidu Hospital, Pune.
