During a yellow fever outbreak in 1878, doctors would observe young men jumping into the beds of people who had just died from the disease in hopes of catching it. Beating the disease was thought to give you a better social status and make you immune. In current times, the idea of an ‘immunity passport’ has been floated around for the coronavirus. This would mean that those who have caught and recovered from the coronavirus would be allowed to travel and enter the workplace. However, researchers are warning against this idea as the coronavirus can be deadly, and purposeful infections would lead to more deaths.
