Some common diseases in medieval Europe included the bubonic plague (Black Death), smallpox, dysentery, typhus, and leprosy. These diseases spread easily due to poor sanitation, crowded living conditions, and lack of medical knowledge at the time. The impact of these diseases was significant, leading to high mortality rates and shaping medieval society.
Unhealthy living conditions and the lack of understanding ofhow diseases spread caused many illnesses and deaths.
