The Variola Virus
The Variola virus otherwise known as the Small pox is an enveloped protected DNA containing virus that causes severe illness. Small pox has a history dating back to prehistory times. It is believed to have appeared around 10,000 BC in northeast Africa. Evidence was suggested by medical examination of mummies ; their skin appeared have contain skin lesions resembling those ones that have had small pox. The infection of the variola virus seemed uncontainable during the prehistory times and even during known history dating back to the 18th century. The clearest record for the study of the virus dates back to the well -known Microbiologist Edward Jenner. Because the disease was almost 100% fatal there were scientist searching for ways to perhaps …show more content…
The immunology, however, is quite similar. The Centers for Diseases Control and the World Health Organization has and continues to do research on developing, studying long term immunity, and herd immunity.

First, it is necessary to understand the structure and normal characteristics of the variola virus. The Variola virus is a double-stranded DNA virus, it contains two envelopes; the outer envelope is present only in the extracellular state. The core of the virus contains lipids and proteins and has complex symmetry. The core of the structure contains double stranded DNA and to date, ten enzymes are known to mediate its gene expression and tons of nucleoproteins. The most widely used virus for smallpox inoculation has been vaccinia, which belongs to the genus Orthopoxvirus along with variola virus. Other species of Orthopoxvirus include cowpox (the virus used by Jenner and mentioned above), monkeypox, and camelpox, among others. Its origin is uncertain, and there are many strains of vaccinia with different biological properties. Vaccinia induces both cellular and

To date, there are six vaccines used to vaccinate the public. Each vaccine elicits its own response. The development of Dyvax was created using a similar virus to that of the small pox. It was created from the cowpox virus. The vaccine is administered with a lancet on the arm. After a few days there will be a pustule which suggest that there was an immunity reaction. The Dryvax vaccine red flags the humoral and the adoptive immunity by producing effector B cells and plasma cells. In an experiment conducted by Dr.Shane Crotty of the La Jolla Institute for Allergy and Immunology and colleagues, Crotty cleverley performed

    At the time, weapons for smallpox were being manufactured by two older methods at a top-secret virus-munitions production plant near the city of Sergiyev Posad, forty-five miles northeast of Moscow. At another virus-munitions plant, near Pokrov, about two hundred miles southeast of Moscow, military virus-production specialists converted the plant to the new Vector method of making smallpox in the large virus bioreactors, but they never started the reaction. If one considers that a single person is infected with smallpox it would be considered a global medical emergency.…

    First and foremost, smallpox first diffused from India and Egypt. It diffused all over the world mostly in Europe. Smallpox were first introduced to the Aztecs by the Spaniards. When Europeans got to the Americas they brought more than just smallpox, they brought disease like Cholera and Dengue fever, influenza, measles, and even High fevers, and these diseases were incurable at that time. Not only did the Europeans and Spaniards…

    Black Pox is a symptom of smallpox that is caused by bleeding under the skin which makes it look charred or black. this symptom usually indicates that a person with smallpox is going to die. smallpox was an infectious disease caused by one of two virus variants: Variola major or minor. Variola major was the more severe and more common form, it included higher fevers and extensive rashes. Variola minor was the less common form and far more less severe with death rates of only 1 percent. The Variola virus evolved from a rodent virus between 16,000 to 68,000 years ago.…

    Smallpox is an extremely deadly disease which, in one point in time, was the most feared disease on the planet. In the book Pox Americana, Elizabeth A. Fenn writes about the encounter with the deadly disease in the 1770's to the 1780's. Her book was first published in 2001 in New York City, where she originally wrote it. Her book contains just under 400 words that explain the disease, some of the first encounters with it, who and where it affected people, and how they got the epidemic under control. Pox Americana is a very informative book that teaches the reader various things.…

    There aren’t many cures for Variola Major. But, if a smallpox vaccine is given within 1-4 days after an infected person is exposed to smallpox, it may prevent sickness or make it less brutal. After the symptoms begin, there isn’t much that can be done. Sometimes, medicine can be given for infections that happen to people who have VM. A man named Donald Henderson came up…

    Small Pox History

    The reason for this is that in spite of its indeterminate origin vaccinia virus was the basis for extremely effective vaccines. It is important to notice that orthopoxviruses are known to be immunologically cross-reactive and cross-protective, therefore infection with any member of this genus provides protection against infection with any other member of the genus (10, 13). Systematic vaccination against smallpox began in the early 19th century, but the real breakthrough in the eradication of smallpox happened in 1967 when the World Health Organization (WHO) initiated worldwide vaccination campaigns. The last known natural case of smallpox occurred in 1977 (14). Consequentially, in May 1980 the WHO declared that smallpox had been eradicated, ceasing the vaccination (10, 15 - 17). Because of the cessation of the vaccination against smallpox after its eradication 36 years ago, a tremendous part of the world human population currently has no immunity not only against smallpox, but also against any other orthopoxvirus infections (13, 18). As a consequence of this new situation, there is a possibility for the orthopoxviruses to circulate in the human…

    The “vaccine clerk to the world”, is how Jenner referred to himself, since he travelled the world transferring pock material (Smallpox - The Speckled Monster). The British government compensated him for his service to the world (Smallpox - The Speckled Monster). In order to, honour Blossom (the cow) and Sarah Neimus, the name vaccine was based after the Latin word for cow, vacca (Edward Jenner - Biography, Facts and Pictures). One-hundred years post smallpox vaccine, Louis Pasteur created the rabies and anthrax vaccines (Smallpox - The Speckled Monster). According to Jenifer Ehreth, 5,977,855 lives are prevented annually from vaccination.…

    The discovery of the vaccine for smallpox disease ended a global outbreak of death and helped keep powerful empires from falling. Smallpox ranks among the most devastating illnesses ever suffered by humankind, smallpox is an acute contagious disease caused by the variola virus. The disease is spread through direct contact with infected people or body fluids or with contaminated objects. The disease is thought to have originated in India or Egypt about 3,000 years ago, with the earliest evidence dating back to 1157 B.C. In the 20th century it killed some 300 million people globally (National 1).…

    Smallpox is a lethal infection cause by the variola virus in which pus filled bumps called pox, spread across the body of a person who has a disease. The virus is only susceptible to humans, insects and other animals could not transmit or sustain the virus within themselves. Coming into contact with a person carrying the disease, usually face to face interaction, was the only way to obtain it. Since there is still no known cure for smallpox, scientists use the last two remaining samples on earth to study and find a cure. These two samples are located and hidden in laboratories in the United States and Russia. The risk of the two remaining samples falling into the wrong hands is low but not impossible. The two samples, if used for something like bioterrorism, could wipe out millions of people in a world wide epidemic.…

    Smallpox In Boston

    • 1234 Words
    • 5 Pages

    Between April and December of 1721, over six thousand colonists in Boston contracted a world-wide feared viral infection known as smallpox. After the occurrence of over nine hundred deaths in Boston alone, the infestation of this disease in the colony became known as the Smallpox Epidemic. During the epidemic, it became widely acknowledged that survivors of smallpox were immune to later occurrences of the disease. This led to the consideration of the medical practice of inoculation—the deliberate introduction of the living smallpox virus to cause a mild case of the disease that would provide immunity. In contrast to the claims of its creators, inoculation was not always successful and did result in a small number of deaths in patients, but…

    Varicella zoster is a highly infectious viral disease, known familiarly as chickenpox, which is a member of the herpes group of viruses. Varicella zoster is a DNA virus and is a member of the herpes virus group. Like other herpes viruses, VZV has the capacity to persist in the body after the primary (first) infection as a latent infection.It is usually a mild disease that lasts a short time in healthy children. However, it can be severe in adults and may cause serious or even fatal complications in people of any age. Chickenpox is a vaccine preventable disease, and vaccination is recommended as part of routine childhood immunisation. The vaccine should not be given to children with severe immune deficiency diseases, including HIV/AIDS, or to…

    Every day the body is under attack by microscopic viruses and bacteria. Vaccines work with the immune system, which is the first line of defense against these pathogens, to strengthen its protective response. It can distinguish self from non-self and thus detect and destroy foreign material (VanMeter & Hubert, 2014). Natural active immunity comes from acquiring an illness or disease which means that it takes getting sick to develop resistance (VanMeter & Hubert). A vaccine is an artificial active immunity that stimulates the production of memory T and B cells, thereby reducing the occurrence of infectious diseases (VanMeter & Hubert).…

    Different approaches are employed to generate and also deliver a vaccine; each method has its own merits and demerits. Few of these merits are discussed below: The main advantage of genetically engineered organisms used as vaccines is that the proteins that are formed do not contain the complete viral strain. So it has no risks related to accidental immunization with live virus. Direct cloning into the DNA of vaccinia virus is promising, however vaccines using this method have not been released into the market yet (Nagy, 2001).…
