Recommended: Rabies History
Rabies a viral disease to warm blooded animals, its timeline dates back as far to 2300 BC. Research shows that dog owners of Babylonian city of Eshnunna (modern Tell Asmar in Diyala Province, Iraq) were fined for their dogs biting and causing death to people of the city. Rabies causes panic and fear into people in 1759-1762 making it a grim barbaric scene in London where street dogs were shot and given a reward restricting dogs to a month of confinement. In the 1800 hundreds becoming a widespread problem to the Western, Northern and Eastern part of Europe, Presenting itself back in North America and Canada to England to never go away. A mass of foxes become infected in France in 1803 this to date has been the largest outbreak to be seen killing …show more content…
The virus is classified in the Rhabdoviridae family, a bullet shape virus. That consists of five proteins nucleoprotein (N), Phosphoprotein (P), Matrix protein (M), Glycoprotein (G) and Polymerase protein (L). Rhabdoviruses have two major structures the helical ribnucleoprotein core (RNP) and a surrounding envelope. Shortly after a human or animal is bitten the virus will move along up to the nerves and multiply inside the brain, once inside the brain it will travel back down into the rest of the bodies nerves. Once inside the brain the virus has multiplied and the animal will show signs of …show more content…
In dogs a funny sound to their bark or a droopy tongue will appear, prodromal is the stage of behavior uncommon traits in animals such as wild animals being friendly the second stage is the excited, furious stage where an animal will appear hyperactive and attack any inanimate object. Lastly the paralytic stage the animal has lost mobility in the hind limbs eventually causing death. In human’s hydrophobia a (fear of water) the furious stage is seen in the later stages of the disease, the human has difficulty swallowing shows signs of panic, and cannot quench thirst. Since saliva is the route of transmission when presented with liquids into the infected human it causes muscle and painful spasms. Symptoms can be paralytic, anxiety, insomnia, confusion and abnormal behavior the first signs in a human are flu like
Rabies is a deadly virus that occurs in the brain. It can affect all mammals but the ones that are most commonly found with the virus are dogs, bats, raccoons, skunks, and coyotes. This means that any non-mammal can not contract the virus, such as fish, birds, and reptiles (2). The virus can be contracted by humans with saliva transfer with broken skin contact from an animal which has the disease. As this is the most common form of transferring the disease it is very believable that Tea Cake contracts the virus from the wild dog that “managed to bite [him] high up on his cheek bone once” (1). The rabies virus works by being a bullet shaped virus that directly attacks th...
This virus is similar to Ebola, because it started in the same place. Lab workers in Germany, in 1967, contracted the new virus while working with African Green Monkeys, which had the virus. The virus is described as a hemorrhagic fever. It has a fatality rate up to 90% and spreads through human to human contact. The first symptoms can be as simple as a fever and a headache, then can progress to organ failure, and fatal internal bleeding.
Almost 2,000 died the night of the 1928 storm in Florida. Their Eyes Were Watching God by Zora Neale Hurston realistically depicts the Okeechobee hurricane that struck the coast of South Florida. The incredulous, category four storm produced winds as high as 150 mph and flood waters of up to eight feet. Hurston describes their heart wrenching experience throughout the end of the novel when Janie, the protagonist of the story, survives the devastating hurricane with her husband, Tea Cake. The book shows similarities between the overflow of Lake Okeechobee and the specific weather conditions of the hurricane, but differs regarding the aftermath of the storm.

Josh Boylan, Crawford County Coon Club President states, “Raccoons are one of the smartest animals”. As a veteran coon hunter, he has encountered numerous amounts of raccoon. Not only does he say that raccoons are one of the smartest, he also states they are one of the meanest animals that he has encountered in close quarters, “They will attack anything, they may get there ass kicked in some of the battles, but they will give it hell.”
RSV is an enveloped, cytoplasmic, pleomorphic virus with negative single stranded RNA (3). This virus belongs in the paramuxoviridae family and in the subfamily Penumovirinae. It has a single serotype and two antigenic subtypes, A or B. In total, 8 out of the total ten RSV proteins are seen in infected cells and virions, eight being structural and two being non-structural (3). The viral envelope has three glycoproteins: G, F, and SH protein (4). In addition, RSV has 5 other structure proteins which include L, N, P, M and M2-1 (4). Two non-structural proteins: NS1 and NS2 are identified with RSV, but it is still unknown whether these two proteins are a part of the assem...
The virus is primarily spherical shaped and roughly 200nm in size, surrounded by a host-cell derived membrane. Its genome is minus-sense single-stranded RNA 16-18 kb in length. It contains matrix protein inside the envelope, hemagglutinin and neuraminidase, fusion protein, nucleocapsid protein, and L and P proteins to form the RNA polymerase. The host-cell receptors on the outside are hemagglutinin and neuraminidase. The virus is allowed to enter the cell when the hemagglutinin/ neuraminidase glycoproteins fuse with the sialic acid on the surface of the host cell, and the capsid enters the cytoplasm. The infected cells express the fusion protein from the virus, and this links the host cells together to create syncitia.
Back in the ancient’s time during the pre-historic era as far as 1000 AD this disease was not very much known to people but have said to be found on an Egyptian Pharaoh Ramesses V mummy who died in 1157BC (Henderson, Fenner, Arita, Ladnyi, 1988 p 209-210). There was evidence of pustule eruption and rash that have been seen on the mummy similar to the description of a variola virus. Part of the idea of where this disease came from is unknown and where the origin of this disease is very much not clear. This disease that is known to be contagious and deadly at times is called smallpox. The early civilization had believed smallpox was originated from Africa and soon had spread though out the world like China and India (Fenn, 2003).
A “vaccine” or otherwise known as a vaccination, is something that stimulates someone’s immune system from a disease. Vaccines can prevent infections and actually cause it to not re-occur again. The invention of the Rabies, and Anthrax vaccines not only saved life’s, but helped scientist conduct and produce more accurate and successful research. Discovered by Louis Pasteur, in 1882, the innovation of the rabies vaccine was invented. Rabies is a critical and sometimes fatal infection that one could get with coming in contact with a “rabid” or wild animal. When this virus enters the body and spreads, it travels slowly through all the nerves and all the way to the brain. Once it reaches the brain, it becomes fatal. The number of deaths due to rabies worldwide each year is approximately 55,000. However, due to the invention of the rabies vaccine, the number of fatalities and illnesses decreased by a substantial amount.
Long before humans established their existence on Earth, microorganisms have always existed. Such is the case for a specific virus named rabies. People in the past could easily identify the presence of this tiny killer. Extending way back to about 2300 BC, people in ancient Babylon have acknowledged the presence of this terrifying disease. Furthermore, they even set up written laws, requiring owners to quarantine their rabid animals or risk being fined a certain amount of money if the animals attacked anyone (West 12-13). In the fifth century BC, a few famous Greek and Roman writers, such as Democritus, Aristotle, Hippocrates, Plutarch, Xenophon, Epimarcus, and Virgil, also mentioned rabies in their writings. However, during times where culture played a bigger influence than science, people typically documented the disease in an ambiguous and vague fashion. In Greek mythology, the god Aristaeus cancelled out the effects, while the goddess Artemis spread the disease to humans and animals alike, cursing them to a state of madness (Baer 1). Only until the first century AD that a Roman celebrated physician called Aulus Cornelius Celsus accurately described the disease (Rabies.com). He also stated “saliva was ‘venomous’ and the means of transmitting the disease” (West 13). In American culture, this disease has also made its mark on humanity because of the way one dies but also the way the person’s death affects everyone around them. In the two famous novels Their Eyes Were Watching God by Nora Hurston and Old Yeller by Frederick Gipson, the great emotional pain deeply scars the heroes of the stories. In Gipson’s novel, Old Yeller, a young boy’s beloved dog, is injured while saving his human family.
Viruses can do many different things to a body, they can destroy, corrupt, and take over cells in the body. They can damage parts of the body or make your body destroy itself, viruses are dangerous but sometimes can be cured. Viruses do not have the enzymes needed to carry out life so they use other’s cells, called a host cell, to live and to perform their functions, such as reproduction. Viruses inject their genetic instructions into a cell causing the cell to create viruses materials, which become new viruses, and usually break the side of the cell destroying it. The viruses can cause parts of the brain to react and activate, causing behavioral changes. For example a disease called Toxoplasmosis can alter rat behavior, while it affects humans in a different way than rats, its an example of what viruses can do. The virus switches the triggers that causes neuronal reactions for fear and arousal, so that what causes fear actually cuses arousal. This is so that the rat gets eaten by a cat and a parasite (which injects the virus) inside the rat can reproduce in a cat. A virus doesn’t simply just head to the brain to cause these things, as there is a “shield” around the brain that protects it from everything. This “shield” is called the Blood Brain Barrier, the BBB, which molecul...
Vaccines have been around for hundreds of years starting in 1796 when Edward Jenner created the first smallpox vaccine. Jenner, an English country doctor noticed cowpox, which were blisters forming on the female cow utters. Jenner then took fluid from the cow blister and scratched it into an eight-year-old boy. A single blister came up were the boy had been scratched but it quickly recovered. After this experiment, Jenner injected the boy with smallpox matter. No disease arose, the vaccine was a success. Doctors all around Europe soon began to proceed in Jenner’s method. Seven different vaccines came from the single experimental smallpox vaccine. Now the questions were on the horizon. Should everyone be getting vaccinations? Where’s the safety limit? How can they be improved? These questions needed answers, and with a couple hundred years later with all the technology, we would have them(ncbi.nlm.nih.gov).

The virus was the biological agent that lived in the host monkey which is the reservoir. Since it was residing in the monkey, it is known as a zoonosis. The portal of exit and transmission is the reason why the virus was able to spread to the people. The monkey is able to spread the virus to the people by direct contact such as spitting, biting or scratching. The portal of entry is when the agent enters humans via respiratory or skin contact. The epidemiological triangle included the pathogen, which was the virus, the host, which was the monkey and the environment. The host is immune to the mutated virus because it has antibodies that can cure the
