Thanks for your video. It's interesting. Sorry for the man died from the needle got into his bloodstream. Well, it does happen. In 1988, my shanghai neighbor's son, only age 42, was walking in an alley with deep raining water in his sandals. He stepped on a rusted nail, which pinched into his left foot. That night, he had a fever, he thought it's just flu/common cold, did not go to hospital. Two days later, he died from virus contracted from that rusted nail.
