    In 1981, a new fatal, infectious disease was diagnosed--AIDS (Acquired Immuno-Deficiency Syndrome). It began in major cities, such as New York, Los Angeles, Miami, and San Francisco. People, mostly homosexual men and intravenous drug users, were dying from very rare lung infections or from a cancer known as Kaposis sarcoma. They have not seen people getting these diseases in numerous years. Soon, it also affected hemophiliacs, blood recipients, prostitutes and their customers, and babies born from AIDS-infected women. AIDS was soon recognized as a worldwide health emergency, and as a fatal disease with no known cure, that quickly became an epidemic. When high-profile victims began to contrac ...

  • The Impact Of Infectious Disease In The New World - 1,196 words
    The Impact of Infectious Disease in the New World "It is often said that in the centuries after Columbus landed in the New World on 12 October, 1492, more native North Americans died each year from infectious diseases brought by the European settlers than were born." (6) The decimation of people indigenous to the Americas by diseases introduced by European invaders is unprecedented. While it is difficult to accurately determine the population of the pre-Columbian Americas, scholars estimate the number to have been between 40 and 50 million people. The population in Mexico alone in 1519 is believed to have been approximately 30 million. By 1568, that number was down to 3 million inhabitants. ...

    ... period was a long 10-14 days and because of this unsuspecting traders carried the virus all over the New World. "In general, the epidemics moved from east to west, loosely following the extent of European-American Indian contact:" (4) This was compounded by the high population densities of large Inca and Aztec cities and a more sedentary lifestyle for the Indians. By the time Pizarro and his conquistadors reached Peru in the 1520's, the Incas had already suffered from the ravages of smallpox. The epidemic left their leader dead with no clear successors which caused political unrest and the civilization was split into two easily defeated armies. One Spanish contemporary wrote at the time ...

  • Abstinence - 1,012 words
    Abstinence With all the emphasis on the importance of using condoms and birth control to ensure safer sex, I feel an intelligent choice is being overlooked. What is this choice? Well, it is sometimes looked at as old-fashion or not as a plausible decision. I feel, though, that it is very possible, and I am living proof that it is. This decision that I have made is pre-marital sexual abstinence. First of all, I want to say that I feel that people should be educated about condoms and other forms of birth control. Being responsible enough to take those measures when dealing with sex is important in and outside marriage. Also, I would like to say that I am not looking down on anyone who chooses ...

    Aids In Africa Horrors in the news Action on AIDS in Africa Imagine 40 million hungry and destitute orphans in sub-Saharan Africa by the year 2010 roaming the streets without schooling and work, prime candidates for the criminal gangs, marauding militias and child armies that have slaughtered and mutilated tens of thousands of civilians in countries like sierra Leone and Liberia in the last decade. This is the kind of nightmare that prompted the united nations security council to convene yesterday for an unprecedented examination of health issue- the global spread of ADIS, especially in sub-Saharan Africa, where experts predict that more people will die off AIDS, in the next decade than have ...

    AIDS In Detail Acquired immunodeficiency syndrome (AIDS). Today, despite the continuing production of better antibiotics since the discovery of penicillin, we are facing an infectious disease against which all these drugs are virtually powerless. This disease is spreading inexorably, killing more people and more people each year. AIDS does not know no national boundaries and does not discriminate by race or sex. It is rampaging not only throughout the United States, but also through Africa, India, China, Russia, Europe, South America, and the Caribbean countries. Even infants and children are at risk. AIDS is similar to the bubonic plague or the "BLACK DEATH" that killed perhaps one-third in ...

Homosexual men have higher rates of sexually transmits diseases than heterosexual men and women because gay men tend to have larger numbers of different sexual partners, more often engage in furtive (anonymous) sexual activities, and more frequently have anal intercourse. PUZZLING SYMPTOMS Any theory of the new disease also had to account for a puzzling factor: the variety of symptoms seen in AIDS patients before they entered the final phase of complete susceptibility to opportunistic infections and cancers. Interviews with AIDS patients revealed many had been very sick for up to a year before they developed their first case of Pneumocystis pneumonia or sho ...

  • Biological Viruses: All Time Enemies - 1,170 words
    Biological Viruses: All Time Enemies First came fever. Then Hamid Mansaray, a young nurse's aide at a remote African hospital, began to hemorrhage. Blood erupted from his nose and mouth. It burst out of capillaries beneath his skin and eyes. By the time I reached the village of Panguma in Serria Leone, Mansaray lay isolated in a special ward. Doctors had diagnosed an obscure illness called Lassa fever. Its cause was a virus, an infective agent so small that 100,000 of them clumped together would still scarcely be visible. Viruses are little more than bundles of genes - strands of DNA or RNA, the molecules that carry the blueprints for all life. Yet viruses are far from simple. They invade ar ...

In 1882 Robert Koch discovered that the connection between human and animal Tuberculosis actually were established. When Koch realized that children were becoming infected from contaminated cows milk most nations brought out legal instruments designed to remove chronically infected animals and take a look at the public health aspect of the problem. The Disease Mycobacterium bovis is the bacterium that caus ...

  • Child Development - 623 words
    Child Development Chapter 9: Developmental Psychology I Teratogens are any medication, chemical, infectious disease or environmental factors that interfere with the normal development of a fetus that can result in a loss of pregnancy, birth defect, or a pregnancy complication. A wide variety of factors include: drugs, alcohol, and viruses. Through techniques of ultra sound and amniocentesis, one can determine the health of the fetus and determine whether terotagens have had any effect. Ultra sound involves directing high-pitched sound waves toward the fetus. A computer converts the waves into a sonogram (outline image of the fetus, uterus, placenta). Amniocentesis is the withdrawal and analy ...

    ... ltifactorial nature of viral evolution makes it difficult to predict such events. According to Doolittle, retrovirus evolution is sporadic, with retroviruses evolving at different rates in different situations. For instance, the human endogenous retroviral element is shared with chimpanzees, indicating no change in over 8 million years, whereas strains of HIV have diverged in mere decades. Endogenous retroviruses carried in the germline evolve slowly compared with infective retroviruses. Generation of new viral pathogens is rare, and often possible only because of high mutation rates that permit many neutral mutations to accumulate before selective pressure forces a change.

    ... free-rider problem applies to the situation of illegal immigration since these immigrants make use of public goods while not paying income taxes. One major problem of illegal immigration involves the fact that illegal immigrants do not spread out evenly across the nation. They concentrate in certain areas, and the destination states that they choose, like California, pay a heavy toll. U.S. households, in general, end up paying an enormous amount of money because of illegal aliens. A study has found that illegal immigrants drain about 2 billion dollars a year for incarceration, schooling, and Medicaid from destination states such as Texas, California, and Florida. In California for examp ...

They gave away their rights, and the Federal government does not have the money for water irrigation projects that would benefit so few people. There is another side to the Indian issue, "first in time, first in right". this means that the Indians were there first, before the laws, so therefore the Indians have first right to the water. This would put a totally different slant on distribution of Colorado River water, but most people feel that this issue would be tied up in litigation for years, and because of the benefits of so few, the Indians would likely lose. Citizens groups have become more vocal in the ...

  • Hamlet - 901 words
    Hamlet The story of Hamlet comes from a long line of revenge tragedies in which a character attempts to avenge the murder of a family member. Just as revenge is present in literature, it is also present in todays society. It is always there, lurking in the darkness of the human mind, watching, waiting for an opportunity to lash out at the surrounding world. Shakespeare suggests in Hamlet that revenge is a debilitating force, and the pursuit of it can infect the most noble of all souls. Once tainted by this infectious disease, no weak minded individual can be cured of it. Revenge is an unavoidable power moving the mind closer towards destruction. In order for revenge to truly corrupt Hamlet, ...
