People in London tried many different things to try to treat the plague and stop it from spreading. At the time, nobody understood what caused the plague, how it spread, or how to treat it. Antibiotic medications, which are the only treatment for plague, would not be discovered for another 300 years. People were so afraid of catching the plague from other people that they threw dead plague victims' bodies in overcrowded pits and buried them all together, as quickly as possible. In one parish in London, 1,114 dead plague victims were buried together in a hole that was fifty feet long and twenty feet wide.
