The outbreak of the plague:What caused the black death.The Black Death was caused by house rats also called as black rats. It could be spread from rat to person if a flea that bit the rat, then bit a person. Scientists thought that the plague started at lake Issyk because places around the lake were infect with the Black Death.

Blood, death and boils:Before you would ever die you would have a boil. A boil starts as a hard, red, painful lump usually about half an inch in size. After you get one boil you may get a fever or get more boils. The boil would ose puss on the victim. Then the victim would cough up blood. Then vomit for two to four days and then die very soon. Bloodletting: People thought they could be cured by using the bloodletting technique. First you cut the victims arm open, next you let it bleed in a bowl for a bit. This technique was you because doctor thought that the plague was in your blood and could be bled out.The only people that did bloodletting was plague doctors. This technique did not work and could kill a person if they bleed too much. Hygiene: Part the reason they got the plague is that people back then did not dispose waste properly and did not have good hygiene. They rarely took baths or showers. They wash hands in cold water because only rich could afford warm water., that meant that bacteria could still be there. They thought that jews were the cause, because few of them got sick.
