Mansoor Khan and his wife Latifa Bibi (pictured below) have been collecting scraps of plastic and other items at an enormous landfill site on the outskirts of New Delhi for nearly 20 years. The $5 daily earnings enable their three children to go to school, in search of a better future than their parents' lives amid the stench of rotting garbage. But over the past few months, increasing amounts of biomedical waste have been arriving at the dump - a result, experts say, of the novel coronavirus pandemic and a huge risk for those who work there. Spread over 52 acres and rising more than 60 metres, the site is littered with used, plastic coronavirus test kits, protective gear and cotton stained with blood and pus - among hundreds of tonnes of waste coming daily from across the Indian capital, including small hospitals and nursing homes. Sifting with bare hands, hundreds of scavengers including children expose themselves to a disease that has infected more than 15 million people globally and claimed over 600,000 lives.
