The chief minister, however, said that despite the panic buying of face masks, there was 'no scarcity'.

Asked if there was a shortage of masks and the consequent black marketing of the product in Delhi as reported in the media, Dikshit said: 'No I don't think so - so far we have had no scarcity. We are reviewing it all the time and our ministers, the health minister and secretary are doing it. In fact, I called myself last night and I was told there is no scarcity.'

She held that quarantine was important in swine flu patients. 'Finally, quarantine is very important - both at home and work places and other places.'
