Other schools are also playing safe though there has been no such case among their students. They are taking all precautionary measures to avoid a swine flu outbreak in their campuses.

Said Shyama Chona, principal of the Delhi Public School, R.K. Puram: 'We have been sending SMSes to parents asking them not to send their child to school if they have a cold, a cough or even slight fever and get them checked by a doctor.'

'We have also ensured that all class teachers keep an eye for any flu symptoms amongst the students and inform the parents accordingly,' Chona told IANS.

Similarly Madhulika Sen, principal of Tagore International school, said: 'We have a well-equipped medical room in our school and any child who feels unwell in class with fever or a runny nose is immediately sent there.'

'Even then we don't keep the child in the medical room for too long and inform the parents straightaway so that they can pick him up and get him checked by a doctor,' she added.

Students with flu symptoms - fever, runny nose, sneezing, cough - that are common to swine flu as well are also tracked by the schools, Sen added. If any child is absent for three days, the school is getting in touch with the family to know why.

Students are also being sensitised about various precautionary measures like staying away from crowds and washing their hands regularly.
