Bioterrorism: Smallpox Smallpox is a highly infectious and fatal disease caused by the Variola virus. It causes extremely painful pustules to sprout across the entire body. Spread from human to human, it has since been eradicated from the world through the efforts of the World Health Organization. However, there is a distinct possibility that it may be reintroduced through bioterrorism. Biological weapons may cause another pandemic to erupt across the world and kill millions of individuals.
It has greatly influenced human populations and human history, and even today, malaria is a leading cause of disease and death in the world with over one million deaths every year (Sherman 91). This means that every 30 seconds, a person dies from malaria. Unfortunately, the general public knows only little about the disease, which is one of the key reasons as to why so many people suffer from malaria. However, since the turn of the 20th century, a great deal of knowledge has been uncovered by microbiologists about this merciless killer. The biology behind malaria is extremely complex.

Variola rex (Smallpox) Smallpox is a virus that was first founded in ancient times. The virus?s proper name is Variola rex, and it has various different forms as well as various symptoms. Among these forms are typical smallpox, hemorrhagic smallpox, and malignant smallpox, all of which usually always cause death in their victims. Some of the typical symptoms of smallpox include red vesicles and pustules all over, bleeding from all orifices of the body, swelling in the face, throat, and eyes, difficulty eating and swallowing, delirium, malaise, deterioration of the bone marrow, lymph nodes and mucus membranes of the body, and a multitude of other secondary symptoms. Smallpox is typically diagnosed by ruling out the possibility of other viruses, which manifest themselves initially in a similar way, such as measles, and chicken pox.
Bioterrorism and Plague Plague, also known as Yesirnia pestis, has wreaked havoc since the first documented outbreak in the 6th century, along with changing the course of history. Although bubonic plague is the most common form of plague, pneumonic plague is the more fatal form of the bacteria. It is the only form that has been successfully aerosolized by man and has the potential of taking down a mass of people in days. If used as a bioweapon, it would cause major damage. This paper is designed to inform you of the history, the facts, and the precautions needed to prevent a bioterrorist attack.
From the common cold to cancers, viruses plague humans with disease and misery. Some of them, such as influenza, adapt and evolve as quickly as defenses are built against them. Some get into cells and start replication immediately. Others lie dormant like opportunistic predators until conditions are ripe for them to propagate. The herpes viruses can do this over and over again.
This part of the essay will give you the who, what, when, where, why, and how of the rabies infection. The infectious disease known as rabies is a virus that spreads from the wound to the central nervous system, causing the body to malfunction until finally crashing down. This virus is a transmittable disease that that runs in both humans and animals. In order for the virus to be transmitted, the saliva from the rabid animal needs to enter the open wound. There are many symptoms that prove that the bitten victim has rabies, one of them being death.
Today, bacteriologists and other scientists have discovered a great deal regarding this deadly disease. We now know that it is a zoonosis disease that begins in rodent-like animals, like mice, squirrels, chipmunks, among other things (Shannon 2014). Scientists have categorized the types if the plague into three groups, and determined the vectors for each. They also revealed that it is caused by a bacterium, that evolved throughout time and is responsible for the certain epidemics and pandemics that occurred in the past. The three types of plague are pneumonic, bubonic and septicemic plague.
VHF is caused by four different RNA viruses, which are all coated in fatty material made of lipids (Center for Disease Control n.p.). The four families, filovirus, arenavirus, bunyavirus and flavivirus, are considered VHFs because they have been known to cause fever and bleeding diathesis (Fong, Alibek, 169). In other words, VHF causes severe hemorrhaging, or bleeding, and destroys the body?s ability to recover (Center for Disease Control n.p.). Most VHF viruses except Rift Valley fever virus and the flaviviruses can b... ... middle of paper ... ... Network, ?Marburg Virus Death Toll Hits 180.? cnn.com.
