Smallpox Advantages And Disadvantages

Introduction

In the past, people believed that the deities existed, and they controlled the world. Also, human beings were not defeated by some powerful diseases, and they believed that the diseases came from God’s punishment. It killed a great number of people. People felt weak, apprehensive, and terrified. The main reason why people were terrified of the diseases is that they couldn't find some methods to treat or prevent the diseases. In history, many deadly diseases caused huge damage to cultures or countries, so we should have known smallpox that had effect and cause many people between present and the past.

Background

Most people known that smallpox was a serious disease, but they were not clearly understanding what causes smallpox was. Some simple introductions about smallpox is that smallpox was one kind of contagion, and if you got it, the red spots appeared first on your face, hands and forearms, and later on your trunk. In fact, the origin of smallpox was one kind of powerful natural disease

that was lost in prehistory (Stefan Riedel, 2005). It means smallpox appeared early, and it affected people’s life a long time ago. However, people were not real aware of smallpox disease until they discovered smallpox vaccine. According to research by Stefan Riedel (2005), the only way to prevent smallpox is smallpox vaccine that was discovered by Dr. Edward Jenner in the late 18th century in Europe. It shows that people had been finding a method to prevent smallpox disease for several decades ago, and they began to research and treat smallpox. Thus, smallpox vaccine was discovered, that people were improved immunity by smallpox disease physically and mentally.
Cause
One cause of smallpox disease is a new virus into the human body. When this virus came to your body, it could live in everywhere and seem like to seed in your body. Smallpox is caused by a poxvirus called variola that contains double-stranded DNA (MedicineNet, 2015). It shows the variola could be easy to live because it had owner double-stranded DNA, and it didn’t need parasitism to another sell.
Another cause of smallpox is infectious ways that are too many and direct. A poxvirus can transit in the goods and air to spread another person. According to research by San Francisco Department of Public Health (n.d.), smallpox virus often rely on contact, coughing, sneezing, and talking to spread from an infected person to another person. This means the smallpox virus can be spread easily and fast in people’s live. In addition, some social problems can expedite transmission of poxvirus such as population crisis. In the article “Edward Jenner and and the history of smallpox and vaccination,” Stefan Riedel (2005) mentioned smallpox appeared in Americas because many slaves came from regions in Africa where smallpox was endemic. This shows the slave trade is one of factor that cause smallpox virus spread rapidly.
Effect
Smallpox affects people’s live. It was one of the most devastating diseases known to humanity in the world, and it caused over a million deaths. Smallpox killed too many people in history, so people never forgot that smallpox killed their friends or families. About 300 million to 500 million deaths from smallpox worldwide during the 20th century, and people who got smallpox disease could be blindness (MedicineNet, 2015). It shows that smallpox disease was terrified, and when people got smallpox virus, they could be die or . Indeed, they didn’t know what they should have done to prevent it, and they only accepted or suffered a result of death. According to research by Stefan Riedel (2005), smallpox was one of the reasons that caused the Roman Empire to die out. It also stated that smallpox is so powerful. We know Roman armies were very powerful, but they couldn’t defeat smallpox disease. It destroyed the powerful Roman Empire. On the other hand, smallpox existed a long time ago to kill people. Smallpox has been a scourge against humanity for at least the past 1500 years, and perhaps much longer than that. (Edward & Allison, 2003). This means we can’t count how many people died because of smallpox in the past 1500 ago. It must have been a lot of deaths. According to the article “A Look at Each Vaccine: Smallpox Vaccine” by Paul A. Offit (2014), smallpox has probably killed more people in the history of the world than all other infectious diseases combined. It also shows smallpox disease killed too many people.
However, smallpox not only affects people’s lives, but it can also appear in military. Because of the powerful smallpox disease, some people might generate a strong desire, that they want to control it to make the scary biochemical Weapon. After 911— the attack on the World Trade Center on September 11, 2001, smallpox has been identified agent of bioterrorism (Riedel, 2005). This event made the governments to pay more attention to the smallpox virus. In addition, smallpox is one kind of infectious disease. When it appears in developing countries which have a large population crisis, smallpox seems like a nuclear weapon. At the moment, smallpox could kill over a million people. In addition, many countries use the smallpox virus in the war. The devastating effects of smallpox have become a biological warfare—“ During the French and Indian War using smallpox diminished American Indian population hostile to the British ” (Riedel, 2005). In other words, people began to use the smallpox virus to create the war, and killed more and more people.
Solution—Development of smallpox vaccine
Now, smallpox is already becoming historical disease because we are successful to find a smallpox vaccine that can prevent smallpox virus.

The smallpox vaccine can protect people that is only way to prevent smallpox vaccine. In the article “ Smallpox Vaccine,” by FamilyDoctor (2012) stated that the smallpox vaccine was used to wipe out smallpox disease until the early 1970s in the world, and it much like other vaccines can protects people against infection by helping their body develop immunity to the smallpox virus. It shows the smallpox vaccine is a more effective method to prevent smallpox disease. Besides, people can get smallpox vaccine easily, and they can save it. According to research by World Health Organization (2014), the vaccinia virus is remarkably stable because it stored under appropriate conditions for as long as 18 years have not lost their potency. Therefore, the governments or some international organizations can save a lot of smallpox

vaccines.
Problem
The smallpox vaccine is not without some risks that has many limits and defects. The first risk is that not all people can get smallpox vaccines. Some specific throngs should not get the vaccine such as pregnant women, children younger than 12 months of ago, and people with weakened immune systems (CDC, 2007). This limits cause the specific throngs get smallpox virus easily because they all have a weaker immune system. Another risk is that the vaccine has many side effect, but the severe side effects following administration of the smallpox vaccine do occur are relatively uncommon. About two of every 10,000 people might get the vaccine will develop a generalized rash that spreads to the body, and about one of every 100,000 people who get the smallpox vaccine will develop an infection of their brain(Cleveland Clinic, n.d.). This shows the vaccine has a obvious risk even though it is uncommon.
Conclusion
Smallpox disease is not terrified, but the terrified thing is that people give up to find a way of treatment to prevent disease and understand disease. Therefore, we should have known some powerful disease such as smallpox that had effect and cause many people. Also, I hope this essay can help people understand smallpox disease. When we face a new disease that seems like smallpox, we can find the same way to research or overcome it. We can avoid waste of time in ignorance for a new disease.
