The Maharashtra government Monday decided to close down all schools, colleges, cinema halls and malls in the Pune-Pimpri-Chinchwad region to arrest the spread of the swine flu.

However two Mumbai schools -- St. Dominic Savio National Open School in Andheri East and Arya Vidya Mandir school in Juhu -- were shut for a week Monday after three students were found positive.

Last week, the Dhirubhai Ambani International School, Bandra-Kurla Complex and the J.B. Vachha School, Matunga, were shut for a week after some of their students were detected with H1N1 virus.

In Delhi three schools closed down for at least a week after some students tested positive for the H1N1 virus.

In Bangalore, the Frank Anthony Public School announced it will remain closed for a week from Monday as a 14-year-old boy tested positive.
