cbs' chris livesay has the story from new dheli. >> reporter: his name was dal chand sagar. a bank teller, a father and a covid victim. his son says the government is too busy to remove his body. only this charity will. it's horrible to think how long this person would have been left inside of their home to decay, if it weren't for volunteer's like these risking their lives to give them a proper cremation. just one of the latest casualties in this country's battle with covid.vi since sagar died at home, rather than a hospital, he's not even included in the official death toll of more than 380,000. the real number could stretch into the millions. and if that wasn't bad enough, doctors are now seeing another disease, specifically, in rural areas that attacks covid survivors, and it kills half the people who get it. it's called mucormycosis, a fungus found in soil, dangerously prevalent where hygiene is lacking and deadly when a patient's immunity is weakened by coronavirus and the steroids used to treat the severely ill says dr. chand wattal of new delhi's ganga ram hospital.

in ancient times it held workers, fighters and exotic animals, and our chris livesay joins from us deepent romans screaming for blood. but not a single one of those spectators ever got to see the coliseum from down here. as a theater in the round, the coliseum had no backstage. instead, as russell crowe's character in "gladiator" found out the hard way, it had an understage teeming with surprises. >> you can imagine how astonishing it could be for the public and also for the animal. >> like a jack in the box. >> and now the coliseum is allowing visitors inside the deepest depths of this layer known as the hypogeum. it's been a while. it hasn't raised the curtain since the year 523, says technical director barbara nazio. >> more or less 100,000 people could work here in the backstage. so just imagine to keep alive a hippo. >> there were hippos here? >> reporter: you can still see the hoists that housed the greatest effects the world had ever seen. >> it was a very, very beautiful show. >> but a very bloody show, too, no? >> everything was bloody. >> reporter: not just gladiators. even co

chris livesay visited the specialized company in northern italy that makes steering wheels and embroideryrn italy, plus an attention to detail that's even caught the eye of two popes. what do 200-mile-an-hour race cars have to do with a 2,000-year-old catholic church? well, it's all in the stitching. the stitching of handmade steering wheels and the stitching of popes' hats. johnny anzi managed mpi, a company that makes the steering wheels. >> it's all handmaid. >> first, the base is aluminum covered in leather. this may seem like a small part of the car, but when you consider this is where the driver's skill comes in direct contact with the machine, every tiny detail here packs a huge punch on the track. and a huge punch in the catholic church. you see, each steelering wheel is done by a husband and wife team. >> you made this for the pope. >> si. >> both john paul ii and benedict xvi not to mention dozens of cardinals have worn the hats called mitres to the stolls around the collar. they always pay obsessive attention to detail. you have to be crazy to do this work, he says. we don't do

chris livesay has the story from new delhi. >> reporter: good morning.. now as the pandemic rages, they're also typifying efforts to save lives. one rushes a 60-year-old patient to the hospital. another zooms food to victims and their families. it's a lot to ask of these modest three-wheeled taxis, but as india reels in a catastrophic second wave of covid, heroes have emerged in unlikely shapes and sizes. new delhi is choking under covid, says cabbie raj kumar. "i'm provided this ambulance service to help the public. if everyone stayed home because they were scared, who's going to help those in need?" other rickshaw drivers organize here at the gurudwara bangla sahib, a sikh temple where cooks prepare 35,000 hot meals every day. zipping them out to the poor among those hit hardest by this pandemic. this country is so huge and the virus so punishing, we have no idea how many people are sick or dead. what we do know is food deliveries like these are one thing helping keep them alive. once they arrive, drivers descend by foot into some of the poorest neighb
