The Black Death caused many deaths. it was a disease spread by fleas and rodents. But also by interacting with someone who had it. They would die slowly. The symptoms are diarrhea and vomiting and etc. more than half of Europe died because they had Black Death.
The doctors tried many things. But most failed. They used rags and smashed garlic.
The doctors got rid of it but it spread some where else.
IIt is not as strong though.
