MUMBAI: It has been a month after swine flu claimed its first victim, Fehmida Panwalla, in Mumbai, and the crowds outside the H1N1 screening centres are growing thinner with every passing day. On Monday, 708 Mumbaikars turned up for testing at the 41 screening testing as against the 4,000-odd who would turn up a month back when the swine flu panic was at its peak.
