Why the Black Death was so dangerous: < it had three different forms,No natural Immunity, people had already been sick from other diseases> < It was easily carried by flees, as the Black Death had already killed a 3rd or Europe’s population it was very serious and scary to know a bug could pass it on to you >
the black death was a widespread disease which was also very lethal and killed many humans and because so many people had it they speard it to other people very quickly
