Anjali Bali, a teacher of the school, said: 'On Thursday a student was suspected to have contracted swine flu. In the evening the child was said to have tested positive, therefore the school decided to remain closed today as a precautionary measure.'

'We had got in touch with students and parents immediately and told them about the school's decision,' she added.

'However, after the student's sample was tested negative at the NICD we are now re-opening on Monday,' Bali, a member of the school's Parents-Teachers Association (PTA), told IANS.

Abha Sehgal, principal of the school, said that after the swine flu scare the school was immediately sanitised.

'We informed the New Delhi Municipal Council (NDMC) about the suspected swine flu case and they took prompt action in sanitising the school,' Sehgal said.
