Virus have been in the air as long as the start of the world as the roman ages there have been a lot of virus. There was the black plauge which killed a lot of people and disrupted the world like when the yellow fever ended farmers wanted more land and the people who surivied the virus got good names and became famous. In the article it pointed out a lot of viruses but I want to do the yellow fever one.
The yellow fever started in the eastern side of the US then when people started running to the western side people got caught and was sent back in fear that they had it so when people found out they couldn’t get through they hid in the forests and fired guns and cannons in to clean the air so in Fever 1793 it said that people threw up black stuff and their eyes became yellow and they saw stuff that other people couldn’t and they got really scared.
