How it Spread
The population of the peasants dropped so dramatically, and more lords wanted the serfs, so they gave more money to the peasants. Their value increased.
If the black death didn’t happen, the social status would have looked different.
Because people know the disease could happen again and know how much it is serious, they are aware of the disease to happen, which makes us safer.
Some people like the scots thought the god was punishing them. Because of the thought, they invaded others, like England, but the soldiers started to get the plague too and spread it to others.
Symptoms
-High fever
-Chill
-Blackened skin
-Vomiting
Some were bitten by fleas and got infected. Also, the bacteria in the air, formed by people who had the virus coughing, was a cause too.

Historians believe Spanish Flu originated in Asia, but the first to report the disease was from the United States. The disease quickly spread to Europe, Asia, Africa, and South America.

Same as the Black Death, people who got the flu coughed or sneezed, and healthy people inhaled the virus in the air, which made so many people sick and die.
-Fever
-Chills
-Headaches
-Body aches
-Fatigue
The flu mainly killed young people, age 20 to 40.
Because the flu occurred in World War II, people thought the soldiers spread the virus.
In the United States, some schools, churches, and other public gathering places were closed.
People were ordered to wear masks, and public places were closed. Also, many businesses closed, and some places didn’t have enough workers. For example, there not enough farmers to harvest crops.
Some countries got more scientific after the virus. And they got better with public health, organizing health data, and other methods. Like black death, people got more aware after the disease happened.

Introduction
There are deadliest diseases that happened in the past affecting the world negatively and also positively. The black death, also known as bubonic plague, and the Spanish flu are two of the diseases. Both populations decreased so much. The black death killed one-third of the population at that time, and the Spanish flu killed 600,000 people in the United States and 500 million people worldwide.
Conclusion
The black death, and the Spanish flu hugely impacted the world, good and bad. The virus spread all over the world, causing many problems. The population dropped, and the jobs and works didn't go well. But, there aren't only bad things, the flu helped develop public health, which is important today. Now people have awareness of the disease to come again, and we can prevent it from occurring. If it didn't happen, then people wouldn't be so mindful about it to happen.
Both the diseases impacted the past, and the future, which is now. For the black death, it impacted a good way for some people like the peasants, but there was damage in the church and other high classes people.
Everybody didn't look at the causes of the same perspectives. Some people blamed others for it, some thought it was a punishment from the god, and many more.
The disease ended killing many people, causing an economic problem, and feudal system, but for some it was good.
In conclusion, both diseases were a problem for most people, but there were benefits, too.
