Lata Ravikar doesn't have a medical degree. Nor does she have any experience of working in a hospital. But the 30-year-old housewife knows a thing or two about healthcare. She can rattle off the ideal height-to-weight ratio for babies, coax new mothers to breastfeed their infants, and show them how to claim government benefits. A mother of two, Lata doubles up as a voluntary community health worker for the Navi Mumbai Municipal Corporation, and she has now become a household name in a slum of Shivajinagar in Nerul, just outside the Maximum City. Thanks to her, the slum dwellers now go to doctors in the nearby public hospital when they need help.
