3. a) The current status of Ebola and Leishmaniasis are deadly diseases according to the World Health Organization (WHO). Ebola is comprised of five distinct species: Zaïre, Sudan, Côte d’Ivoire, Bundibugyo and Reston, which causes 25-90% deaths found in African clinics. Leishmaniasis is caused by parasites which transmit this disease by the bite of a tiny female phlebotomine sand fly. This deadly disease is estimated to infect 1-2 million new cases every year. The two diseases that are similar to Ebola and Leishmaniasis are small pox and Leptospirosis. According to author Laurie Garrett the current status of small pox seems to have decreased over the years until there aren’t any cases remaining. “World Health Organization (WHO) had announced that the last known case of smallpox had been tracked down in Ethiopia and cured”P.2. This is majorly due to the fact of increase investigation of medicine which helped developed a cure. Leptospirosis disease can be found in areas where there is overcrowding, poor sanitation, and poor health care. Authors Colleen Lau, Lee Smythe, Scott Craig and Philip Weinstein said that “Leptospirosis is most likely to occur in urban slums, low-lying coastal areas and small island states”P.23. This tells us that the current status of Leptospirosis is not as common as before because of the advanced urbanization that has been developed in these past years.

b) The organism that caused smallpox to occur is known as variola virus. Variola virus is known as variola minor or variola major. The organism that caused Leptospriosis to occur is Leptospira interrogans which is a bacterium (spirochete).

c) Currently smallpox has been wiped out of the world meaning that there are no cases or prevalence to be found. As for Leptospirosis the last current outbreak of Leptospirosis was at June 17 2004 at Kenya. Nearly 143 cases have been confirmed including 8 deaths because of the outbreak.

d) The social factors which affect the spread of

    Guns Germs And Steel Book Review

    Pertussis was acquired from pigs & dogs. Farmers have increased exposure to the germs of their livestock. In addition, keeping pets, human intimacy with animals, and animal fecal contamination in crowded sedentary urban conditions contribute to the increased exposure of humans. Many disease manifestations serve the needs of the infecting organisms in providing a means of increasing transmission. The transformation to exclusively human diseases involves changes in the intermediate vector and/or changes in the microbe. Newly introduced infections, like smallpox, measles, flu, diphtheria, malaria, mumps, pertussis, plague, and yellow fever, decimated up to 95% or more of the Mississippian Indians, Peruvians, Mexico Indians, etc. Khoisan, Pacific Islanders, and Aboriginal Australians were also decimated by imported diseases. Only syphilis, with its unknown origin may have traveled from New to Old World. The insufficiency of domesticated animals and their noncuddly characteristics prevented New World acquisition of human epidemic diseases from their own domestic animals. Although native endemic tropical diseases did not…

    Small Pox Research Paper

    Smallpox emerged around 200 years after the Black Death, during the mid-14th century, and quickly became one of the biggest killers in the expanding world. (Dobson,p.130) Smallpox changed the beauty standards in Europe through the use of makeup, fashion, and accessories. This disease struck in all social classes of society and was not dependent on status, wealth, sanitary conditions, or hygiene. Because of that, smallpox was sometimes referred to as the “democratic” disease (Skold,p.145) People believe that the Inca and Aztec empire likely collapsed because of smallpox. Hernan Cortes and his 300 men attacked the Aztec capital a force of 300,00 and captured the city within the span of three months. (Altman. p.42) This likely occurred because the Spaniards have had years of exposure to smallpox due to Columbus crossing the Atlantic from Europe to Africa and carrying the disease. (Dobson,p.130) On the other hand, the Aztecs and Incas were not immune to the ravages of the disease and quickly became weak which led to the collapse of the civilizations. (Altman, p.42)…

    Greg Graffin Ebola

    In this excerpt, Greg Graffin exemplifies a specific topic that branches out from his evolution management thesis. He states that the fate of all populations in the end is extinction and to prevent this from occurring, people must come together and focus their attention to populations as a whole instead of individual. Graffin uses the recent war with bacteria, viruses, and other pest populations to offer solutions at how these populations can continue to persist without causing damage. The author previously stated in other chapters that populations tend to persist and are difficult to completely eradicate “artificially”. Nature on the other hand can wipe out entire populations whether by climatic or biological disasters. Therefore, managing…

    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…

    Spread in an almost domino effect, once one country was exposed it was only a matter of time before the next was hit. From Egypt and China the people of Japan developed the decreased because of an increase in trading between the countries. Then, in the 11th century Crusades further spread smallpox in Europe. In the 17th century we then see the movement of the disease over to North America after it is colonized by Europe. In Europe, smallpox is estimated to have claimed 60 million lives in the 18th century alone. In the 20th century, it killed some 300 million people globally (CDC 1). This…

    Hot Zone

    In the late 1900s there were these unknown diseases that were making people die out of nowhere. This made people all around frightened to their wits. No one knew a cure for it or where it originated from. A disease known as Marburg which was first thought to be found in a guy named Charles Monet, caused him to have massive hemorrhages and clotting. This was a deadly disease which could be caught by the person who has it by as easily as it seeping through an open wound. Marburg is a filovirus which can be comprised with two types of viruses called Ebola Zaire and Ebola Sudan. Ebola Zaire is the worst out of the three, killing nine out of ten humans who have it. An incident occurred in Reston, Virginia where monkeys were being transported from the Philippines to a monkey house. Some of the monkeys started to drop dead for some unknown reason, so Dan Dalgard, the veterinarian who cared for the monkeys, contacted the United States Army Medical Research Institute of Infectious Diseases (USAMRIID) to help diagnose the case. Dr. Peter Jahlring, who was a part of the USAMRIID institute, tested the blood of the monkeys. To his horror it came up positive for Ebola Zaire, the deadliest of the strains of Ebola. This caused a panic in him of which he rushed to his head leader and told him about it. No one wanted an outbreak to happen of Ebola Zaire so the C.D.C. and the army banded together to try and stop this horrific disease from spreading. Dalgard turned the monkey house over to them in which they terminated all the monkeys and bleached and scrubbed…

    Pros And Cons Of Ebola

    Ebola is a world issue at this point, as leaders of public health we have the responsibility to make an example of how to handle viral outbreaks. The current ban on visas to those who have been in west Africa is not the way to do this. While some believe that banning these people from entering Canada is the best way to protect our citizens, there are several arguments against the ban. Including that the bans gives incentive for countries to hide viral outbreaks, that this gives incentive for people to travel via les documented means in order to avoid these bans, that these people can not be tracked and helped if they are found to be infected, the several effects that disregarding the WHO, the experts leading world health, can have, and the unjustified reasons for implementation [1]. I will consider both sides.…

    Polio Essay

    Polio Essay

    In this world, there are over 12,000 diseases caused by either bacteria or viruses, and most of them are yet to be discovered. One of the dreadful diseases revealed is polio (which is shortened for poliomyelitis) (Ballard). The polio virus enters the body through the mouth, multiplies in the throat and intestine, and spreads through the blood to the central nervous system. Thus, the virus attacks the CNS, which can lead to paralysis. The paralysis would start with the legs, and would be visible due to the atrophy, and the muscles wasting away due to the lack of use (Hecht). Many have spent their whole life in iron lungs due to paralysis in the chest muscles (Ballard). There are three types of polio: mild, non paralytic and paralytic (Hecht). Only 1% of all polio patients develop paralytic polio (Hecht). In 1947, as Jonas Salk searched for a vaccination, he came upon the conclusion that a chemical called formaldehyde can eliminate the virus (Ballard). Another scientist named Albert Sabin desired to weaken the virus, instead of killing it (Ballard). Thus, this lead to the invention of oral vaccines that people can swallow (Ballard). A severe disease called post-polio syndrome, which is an illness of the nervous system develops, and can appear 15-50 years after a patient has been affected by polio (Hecht). People and children can contract polio due to a variety of factors, which are present in several third world countries. It still remains to be an underlying health problem in many developing countries (Ballard).…

    Ebola

    Nigeria and Ivory Coast restricted flights from Ebola-infected countries, emphasizing fears of the virus in West Africa spreading globally by air travel. The move Ebola is frightening and also it is scary how far it may travel. That is why hospitals from Hong Kong to New York to Cape Town are ready for whatever that comes through those emergency doors. Officials in Africa face a troublesome conclusion in deciding how to increase border controls without shutting off all the travels and trades. It’s hard to control the air travel because it can’t be completely shut down but it is a risk to let others come from West Africa because of the threat of Ebola traveling everywhere. The good thing is every country around Africa is basically ready. For example, airports in Hong Kong, South Korea, Saudi Arabia and the Philippines hospitalized feverish people and checked their blood for Ebola, all of which came out negative. Ebola has killed more than 961 people since the current outbreak and in addition it likely sickened 1,711 others.…

    Leptospirosis Intro

    Leptospirosis is an infectious disease caused by a type of bacteria called a spirochete. Leptospirosis can be transmitted by many animals such as rats, skunks, opossums, raccoons, foxes, and other vermin. It is transmitted though contact with infected soil or water. The soil or water is contaminated with the waste products of an infected animal. People contract the disease by either ingesting contaminated food or water or by broken skin and mucous membrane contact with the contaminated water or soil. The infection causes a systemic illness that often leads to renal and hepatic dysfunction. The disease was first recognized as an occupational disease of sewer workers in 1883. In 1886, Weil described the clinical manifestations in 4 men who had severe jaundice, fever, and hemorrhage with renal involvement.…

    Leptospirosis is a major public health problem worldwide, particularly in the tropics.The clinical presentation of leptospirosis in humans is variable, and can range from a mild flu-like illness to a severe disease with pulmonary hemorrhage, renal failure, and occasionally death. Consequently, leptospirosis is easily mistaken for other febrile illnesses including influenza, dengue fever, meningitis, or hepatitis. Therefore, rapid and appropriate laboratory diagnostic tests are needed to aid clinical case identification and to facilitate the implementation of rapid outbreak investigations for optimal treatment and patient management.…
