to deal with anything like this plague. Doctors then started to wear bird masks, which has a bird-like beak, to prevent getting sick as they believed it was airborne. Witchcraft was another reason they used for the plague, as witch investigators and civilians needed a scapegoat to better explain mass hysteria. But when burning the “witches’ did not affect the plague’s causalities, doctors turned to the astrological zodiac signs for guidance, as they were believed to be associated with several humours, which is another word for cures, in the middle ages. In general, people assume the plague killed people indifferently.
However, the plague was found to have killed more people of old age and poor sickness than those young and healthy. This is because of their poor nutrition that weakened the already feeble immune system, making them even more susceptible to the plague. Scientist Sharon DeWitte conducted a research of the plague’s victims by going to a cemetery and inspecting the bones. “It makes sense that the Black Death would kill people who are already weak,” DeWitte told LiveScience. “What’s important is that we’ve provided quantitative evidence to counter the assumption it killed indiscriminately.” This also gave researchers the idea that plague survivors’ kin would have stronger genetics in the post-plague
era.
