The Second plauge to make the black Death was the pneumonic plague, This plauge was very deadly because it infacted the lungs and it was very easy to get because it travelled thourght the air and to person to person.
The final plauge of the combtion was the Septicemic plague and it was the most aggressive. This plauge flow into the blood steam or your organs and it would go so fast that the person would be able to live one more day.
When the black Death started to die out the Fleas did not have a person to infact so the people could not tranport it to other people
