Rabies Virus Research Paper

Premises support (3): (9) Cats are more likely to carry rabies. (10) They also share parasites or infectious microbes with humans. (11) Outdoor cats are the primary hosts of toxoplasmosis, which effects around 30% of humans.

2 to 4 days after the incubation period, the infected person develops the initial symptoms of fever, chills, head and body aches, and vomit; then, the infected person becomes contagious. Afterward, a rash develops on and in the oral cavity area of the infected person causing the infected to become most contagious. After which, the rash develops to pustular rash, and the infected remains infectious. When the pustules form a crust and then a scab, the infected continue to be contagious. It is only after the scabs resolve and fall off, the infected is no longer infectious (World Health Organization,

Rabies is a fatal disease transmitted by the bite of an infected mammal. The disease travels from the saliva of the infected animal, into the wound of its victim, eventually attacking the brain and nervous system. At that time the virus get to the brain, the victim develops symptoms salivating, walking in circles, loss of appetite, fear of water, and aggression. After

The infected person could feel symptoms less than a week or over a year later (WHO, 2014), in the most extreme cases. Once the incubation period is over and enough of the virus has been replicated, it uses neurons in the peripheral nervous system and exploits axonal transport mechanisms so that it can eventually invade the central nervous system and reach its target – the brain (Gluska, S. 2014). Once in the central nervous system rabies causes acute brain inflammation, causing psychosis and extreme aggression (n.p. 2014). It then travels back through the peripheral nervous system, eventually concentrating in the salivary glands to be transmitted to the next victim. Because of the concentration in these glands, most victims suffer excruciating pain upon swallowing and develop a fear of liquids (Health Central, 2014).

As stated earlier, individuals carry the virus in their saliva, which means that it can be

Apart from food transmission the virus is most commonly contracted via person-to-person contact. Several other ways of transmission include touching surfaces or objects that are contaminated with the virus and then proceeding to

These vectors become infected via blood meals from an infected host which includes, but is not limited to, ground squirrels, wild mice, wood rats, marmots, deer, coyotes, and sheep. Most human cases occur between the months of March and September, with April through July being the peak months. The virus can be transmitted from person-to-person through blood transfusions and mother-to-infant in pregnant women. Laboratory transmission cases have also been reported. Extended viremia observed in both humans and rodents is attributed to the virus situating itself within red blood cells, which enables the viral particles to evade an immediate immune response. In the United States this virus is included on the list of agents screened prior to bone marrow

For one thing, when rabies affects humans that have very similar symptoms of the flu, including discomfort, headache, weakness and fever, and last for days. Though it also includes itching, around the site of the bite, anxiety, and abnormal behavior—[“Rabies -sign and symptoms” Centers for Disease Control and prevention], insomnia — inability to sleep—, hallucinations — an experience of something that is not present (Dictionary), sore throats, fear of water and stiff muscles. The virus soon as it’s in the humans’ body starts to move from the arm or leg, where it was a bit, within a short period of time; it spreads though-out the body and tends to fail internal organs (Rabies Vaccine: Medline Plus Drug Information). For example, according to “National Health Service Choices” in article about Rabies. Brierlie Godfrey, who is an Australian actress living in London, was bit by a wild baboon in Morocco while on holiday. However, some animals have the some similar symptoms such as: fear of water, and change in behavior or personality. Animals also become withdrawn or aggressive. For example, wild animals may lose their fear of humans or pets may become aggressive or withdraw. Often the animal does not eat, may fear water, and have an unsteady gait (Rabies Vaccine: Medline Plus Drug Information). Last of all, these symptoms can roughly permanently fatal. According

Rabies is a highly infectious viral disease that can easily ruin and eventually end the lives of both humans and animals alike. Rabies comes in two forms for animals. It comes in the form of paralytic rabies, which is the kind that puts you in paralysis right from the beginning, skipping the symptoms of agitation and excitability. Rabies also appears in the form of furious rabies, which is completely different in the way that it makes the victim restless, vicious and agitated. When humans get rabies, their symptoms start out with simple headaches and fevers and later progresses to terrible things such as becoming hydrophobic because of painful throat spasms and paralysis. A definite diagnosis of rabies needs lab analysis of

This report will educate the reader on rabies in canines (dogs). It will give the reader a basic understanding of the virus and disease, as well as information on prevention and treatment.

Measles virus, also called Rubeola virus, is a negative-sense, single stranded RNA virus, which belongs to morbillivirus genus in the Paramyxoviridae family. It consists of a helical nucleocapsid, 100-300 nm in diameter, surrounded by an envelope. The envelope is lined by matrix proteins and carries transmenbrane hemaglutinin and fusion glycoproteins which are the virulence factors.

RNA virus of paramyxovirus group causes the disease called Rubella. The whole family is responsible for the disease as it spreads throughout the family. The women who get infected with Rubella within the first 3 months of their pregnancy period ranges almost from 30%–50%, where the fetuses will be poorly affected by the virus. Gestation is the time when Rubella virus choose to invade the placenta and fetus. In this case, a woman in her initial months of pregnancy who is exposed to the virus may grow the infection and give birth to an infant who is seriously infected and displays the congenital faults such as hearing problems along with blindness.[3]

Once infected the typical incubation period for SARS is 2-7 days, however, in some cases it may be as long as 10 days. The illness usually begins with a fever. Sometimes chills accompany the fever and other symptoms including headache, general feeling of discomfort, and body aches. Some people also develop mild respiratory symptoms at the outset. After the incubation period of 2 to 7 days SARS patients may develop a dry nonproductive cough that might be accompanied by or progresses to the point where insufficient oxygen is getting to the blood. The CDC says that SARS

A number of studies have supported the theory that the virus had originally occurred in animals previous to human infections.5 The MERs-CoV virus is a type of coronavirus that has been known for infecting both birds and many species of mammals. These types of infections are commonly referred to as zoonotic diseases because the pathogens are able to be transferred from animals to humans. Zoonosis can happen with or without a vector in order to spread the infection. Although the exact origin of the MERs-CoV infections is unknown, there has been convincing research performed that has found related types of coronaviruses in bats and camels. According to the Center for Disease Control and Prevention, the coronavirus is found in multiple species and can cause respiratory illness and gastrointestinal upset.

Rabies has two phases that occur in both humans and animals: the predominal phase and the neurological phase. The predominal phase begins when the host experiences the first symptoms of rabies. In humans, some symptoms are fever, unconsciousness, vomiting, headaches, double vision, difficulty when speaking, and pain at the origin of the wound. During the neurological phase, paralysis (dumb rabies) and
