Rabies: The Infection
Rabies is an infectious disease that is hard to survive through. Although rabies is mostly found in animals, humans can also carry the virus and spread it amongst others. This virus is well known as the slow virus because it will slowly kill you. There are many symptoms of rabies, in both animals and humans, that reveal themselves only after they have been bitten. 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. This virus is really tricky because not only will you get the virus but you won’t really know if you have rabies until the symptoms reveal themselves.
At the time of the bite, saliva may enter the wound. The only way for the virus to be transmitted is if the saliva is in or close to the nerve tissue. From the nerve tissue, it travels until reaching the central nervous which then spreads to the spinal cord and brain. The virus incubates in the victim for approximately 1 to 3 months. The victim has no symptoms at this time. When it reaches the brain, the virus multiplies rapidly, passes to the salivary glands, and the victim begins to show symptoms. The infected victim usually dies within 7 days of being sick (“Transmission” 2).
We all hear stories about a rabid dog biting a human but we have to consider that not all rabies infections are transmitted by bites; the virus can also be transmitted by non-bites. The non-bites can be scratches, abrasions, open wounds, or mucus membranes contaminated with saliva or other potentially, infections material such as brain tissue from the rabid animal (Coye10). Mammals are the only species that can transmit rabies to one another. Although humans are mammals, they can’t transmit the disease the same way that animals transmit it. One way, which is the only recorded evidence where a human transmitted the virus to other humans, is by organ transplant (“Investigation” 2).
Andrew Suy Professor Owens History 1302 13 April 2016 Polio: An American Story Polio, formerly known as poliomyelitis, an infectious viral disease that affects the central nervous system and can cause temporary or permanent paralysis. A debilitating disease that was once the affliction of our very own republic. David Oshinsky’s Polio: An American Story chronicles polio’s progression in the United States, a feat it does quite well throughout the course of the novel.
[1, 4, 5, 9, 13] There have been no documented cases where a human has contracted the disease from another human. [4] It appears, based on field and lab data, that infection requires direct contact with the virus through means such as contact with infective bodily secretions, urine, or tissues. [12] It is unknown to scientists how the virus can be maintained in the bat populations and avoids extinction as the host species becomes immune to its presence. [14] The incubation period from time of infection to the onset of symptoms is about 5-14 days in experimentally induced animals [4] and 8-14 days in natural field cases.
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.
...at in domestic animals, which indicates wild animals cause a higher risk to humans. Controlling the disease in susceptible wild free-ranging animal populations is implemented by oral vaccination and recombinant rabies vaccine by use of vaccine-containing bait. The best prevention is decreasing chances to expose to the disease. Once a patient is suspected as a rabies case, the physician and local health administrator should decide whether infection actually occurs and whether a risk of rabies exists in the geographic area. Once the identification is completed, the patient should receive post-exposure prophylaxis immediately, which contains the combination of local wound cleansing, human rabies immune globulin (HRIG) and rabies vaccine. The population such as veterinarians, animal handlers that have higher risk to be infected should receive pre-exposure immunization.
The most common way this disease is transmitted from one animal to the next is through mosquitoes. A mosquito carrying infective heartworm larvae bites a dog and transmits the infection to them. The larvae grow, develop, and migrate in the body over a period of 6 to 7 months, in which time they become sexually mature male and female worms. this is the prepatent period. The worms then reside in the heart, lungs, and associated blood vessels. The worms begin to mate and release microfilaria into the blood stream. When a mosquito bites an infected dog it takes in some of the microfilaria in the blood. After 10 to 30 days there is larvae in the mosquito’s salivary gland which can then be passed on to the next dog the mosquito bites.
Rabies does not discriminate against any warm blooded mammal; all that come into contact with the virus are at risk. Those who choose to live, work, and recreation in areas with a larger wildlife population are understandably at higher risk. People should be extremely wary of unknown animals and heed behavior changes in familiar animals. The virus is usually spread from a bite wound when the saliva of an infected animal is introduced to the victim via the bite. The virus travels from the origin of the wound to nerves and onward to ultimately infect the brain.
As the late 19th century progressed, technological ideas and inventions began to thrive. The notion that technology would impact life as we know it was an unbelievable idea to comprehend. People had no idea that something so simple such as the light bulb would become so vital to them and for century’s to come. Inventions such as, the typewriter, barbed wire, telephone, Kodak camera, and electric stove were created, however the major inventions created and use tremendously today are, Medicine, Electricity, and Transportation.
After a few days after developing a rash, it may change into small lumps all over the body. These symptoms may come just after a week of being infected. "The first symptoms may appear 12 to 14 days after you're infected." A rash will appear in the mouth and throat in the first few days, it will then spread to the face and arms and finally, the legs. The rashes will grow bigger as days go by, eventually transforming into large bumps filled with puss and fluid. Then these bumps are replaced with blisters, which will drop off and that indicates that the person has become infected and can possibly spread the disease.
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...

Rabies is a deadly virus spread to people from the saliva of infected animals. The symptoms of rabies are perspiring heavily, shouting at nothing, and hallucination. Poe's doctor, Dr. Henry Wilde, said, "[Poe] had all the features of encephalitic rabies." While in the hospital, Pow was very confused and belligerent, he soon died. He had no bites or scratches, however, rabies can take up to a year to show symptoms. He could have been infected by cats, since he was fond of and had many of them. However, if he did die of rabies, the doctors would have known automatically and wouldn't rule cause of death "unknown." In the 19th century, the rabies virus was very common, all dogs had to be
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.
The discovery of the polio vaccine was an important medical and scientific breakthrough because it saved many lives since the 1950s. In the summer of 1916 the great polio epidemic struck the United states. By the 1950s hundreds of thousands of people had been struck by the poliomyelitis. The highest number of cases occurred in 1953 with over 50,000 people infected with the virus.
The septimic plague is transmitted through direct fleabite. With there being no incubation period the infection infects the bloodstream directly and immediately. In reaction the victim’s circulatory system collapses, they have a high internal bleeding rate, and are dead within the next twenty-four to thirty-six hours.
