Hyderabad, Aug 11 - After the reported terror threat, influenza A (H1N1) cast its shadow over the World Badminton Championship here Tuesday with the doubles coach of the Malaysian team displaying symptoms of the viral disease that has killed eight people in India.

Jeremy Gan has been quarantined at the Andhra Pradesh Chest Hospital, the nodal centre to deal with swine flu cases, and his samples have been sent for testing for influenza A (H1N1) virus, organisers of the event said.

'The Malaysian doubles coach complained of throat pain last evening. His samples have been sent for testing. We don't want to take any chance. We are taking all precautions,' Pullela Gopichand, director of the organising committee and Indian team coach, told IANS.

Gopichand had earlier said the other Malaysian coach, Misbun Sidek, had shown swine flu symptoms.

Since the city has no testing facility, the samples would be sent to the National Institute of Communicable Diseases (NICD) in New Delhi. The reports are likely to be available Wednesday.

A player from Singapore was also hospitalised Monday evening due to ill-health.
