The black death spread from human to human mainly in seliva. When somebody who had the plague kissed a preist for instance, the priest would have the plague. In those times, kissing each other on the lips was a sign of gratitude and friendship and love. It was common to kiss each other which didnt make the plague easy to contain instead of spreading it by kissing their loved ones before they died.
It was spread by fleas, who normally host on rats, yet in some cases, they used humans as a host, and thus started the plague. It cannot be spread from human to human; only way is for the flea to infect you.
poor hygiene
Not usually unless the person who had bubo had started developing septicaemic plague. septicaemic- this plague (there are three different types) affected the lungs and was transmitted from human to human.
One human activity that contributed to the spread of the bubonic plague was the movement of infected rats on ships, which carried the disease from one place to another.
Eating rotten food
Well the plague started to spread because when the rat goes around where the human are , the fleas from the rats it jumps onto the human and sucks the blood and it also spread the plague when the human is not well it spreads to another person, when they can't cure it , mostly millions of people died from plague. Hope this help you :)
