In the Radio Lab the Authors illustrates how HIV is spreading in United States and how the starting point begins as Patient Zero. Jad Abumrad and Robert Krulwich along with Carl Zimmer and David Quammen discuss how in 1981 a mysterious syndrome it became in a pandemic among homosexual people in important cities such as Los Angeles Ney York and San Francisco. Young men were dying in inexplicable conditions that the CDC had to intervene with a several researches, surveys and studies about those cases. During the research noticed that one man were most related with more cases, this person was Gaetan Dugas, a Canadian young men, who travel to US. As he knew he was going to die, he stared to spread the disease for something he called a “gay cancer”.

According to a report published in the February 1998 edition of “Nature”, scientists identified what they believe is the earliest case of AIDs in a man from the Congo in 1959. (Lerner and Hombs 39) By the end of the year 1980, 80 men would have been diagnosed with at least of the opportunistic infections that are a characteristic of AIDs. (Lerner and Hombs 40) AIDs cases in the 1980s increased dramatically not only around the world but in the United States, primarily in larger cities like Los Angeles, New York City and San Francisco. The numbers of AIDs diagnoses and deaths spiraled out of control throughout the 1980s and towards the end of 1989 there were 117,500 cases of AIDS reported and 89,000 related deaths.(Lerner and Hombs 54) In the

In the 1980s, a mysterious disease began to take the lives of Americans. With the cause unknown, a fear grew among Americans. An unusually high rate of people was becoming sick with strange and rare diseases. When experimental treatments failed to work, people died. This mysterious disease is what we now know as HIV–Human Immunodeficiency Virus. In the past thirty-five years, the HIV has taken many turns in history. Although we do not hear about HIV and AIDS now, it is still a prevalent issue in the United States and in the world.

infected family members in several ways. “In many cases, the presence of AIDs causes the

To begin with, many scientists found that HIV is related to a similar virus found in chimpanzee after conducting many researched they believe the virus was passed down from monkey hunters to human. Moreover, the first known case of HIV was reported in 1920 in

When it was first reported, scientists were unaware of the how many people were infected with HIV and how many developed AIDS. By the mid-1980 it was suggested that more than 100,000 men would have already been infected with the virus. In 1983, females were infected with this virus, and at that time, scientists believed it come from heterosexual sex. In the same year, children were infected with this virus. The Centers for Disease Control and Prevention (CDC) reported that casual contact could transmit that virus. However, later that year, scientists said that HIV/AIDS could only pass to someone through sex, by sharing and injection syringe, though breastfeeding, and through contact with the blood of someone infected with the virus (History of HIV/AIDS Overview).

This book talks about how recent genetic evidence form new discoveries have traced the birth of AIDS to being rooted in the southeastern forests of Cameroon in Africa, where chimpanzees had a very similar strain of Human Immunodeficiency Virus in their blood. They carried this simian immunodeficiency virus for hundreds of years without creating any major, large-scale outbreak in humans. The birth origin story of HIV may have been happened sometime around 1880 to 1920. TImberg and Halperin discuss that the birth of HIV most likely occurred when a European hunter traveling in

One of the growing public health problems in the United States today is the spread of the human immunodeficiency virus, or HIV, among the American population. Beginning in the 1980s, the U.S. public health system has been working vigorously to come up with effective methods for preventing the spread of this debilitating virus. HIV has persistently stayed within the human population due to the continual transmission of the disease. Before widespread transmission of HIV, the two most transmissible way of contracting the disease was either using unsterile needles for drug use or by unprotected sex with partners who were infected – most of the infected individuals in the 1980s were those who were or had been in homosexual relationships.

History: HIV was believed to have originated in the Congo, where it was transmitted when a human came in contact with a species of chimpanzee that had acquired the virus. From then on, the virus only continued to spread, where it could have been believed to infect anywhere from 100,000 to 300,000 people (“History of HIV and AIDS Overview”). The first forms of confirmed HIV discovered in the world took forms in two highly dangerous illnesses, Pneumocystis carinii pneumonia (PCP) and Kaposi’s Sarcoma. These rare diseases were first discovered and researched, although they didn’t know they were directly linked

HIV and AIDS have affected millions of people throughout the world. Since 1981, there have been 25 million deaths due to AIDS involving men, women, and children. Presently there are 40 million people living with HIV and AIDS around the world and two million die each year from AIDS related illnesses. The Center for Disease Control estimates that one-third of the one million Americans living with HIV are not aware that they have it. The earliest known case of HIV was in 1959. It was discovered in a blood sample from a man in Kinshasa, Democratic Republic of the Congo. Looking further into the genetics of this blood sample researchers suggested that it had originated from a virus going back to the late 1940’s or early 1950’s. In 1999,

These behaviors, sedentary lifestyle and poor food choices, are further supported by both Patient A and B’s healthcare behavioral display in the hospital. Patient B would not allow the nursing staff or the phlebotomist to draw any blood specimen from him (to include finger stick for glucose checks) unless he has a can of a caffeinated-carbonated drink with all his meals to include breakfast. While Patient A admitted, “I stop eating when I get full,” with his family members bringing in fast-food bought sandwiches in addition to his hospital meal.

The virus has been divided up into three patterns. Pattern 1 is the type of AIDs in North America, Western Europe, Australia, and New Zealand. In these parts of the world AIDs is spread mostly by homosexual intercourse and found in homosexual and bisexual men most often. The number of cases has drastically dropped from blood transfusion due to routine screenings. The sharing of needles by intravenous drug abusers seems to be becoming a huge problem in helping to spread the disease faster. Since homosexual and bisexual men seem to be at a greater risk for the virus, the ratio of men to women is 20:1 in the pattern 1 countries.

That is not to say that an HIV infection among the heterosexual community is unlikely to happen. The CDC reports in 2014, new HIV diagnoses was transmitted through four main ways: male to male sexual contact (67%), male to male sexual contact with injected drug use (3%), inject drug use, and heterosexual contact (24%). Yet, 19% of the heterosexual contact transmission was among women. Of the 19%, the majority of women (87%) primarily encountered the virus through heterosexual contact and the other portion, contracted the virus through IDUs (13%). More specifically, an estimated 6% (2,635) of HIV diagnoses was due to IDUs. The figure below represents disparities in newly HIV diagnoses among the most affected populations in 2014 according to race, gender, and sexual relationships such as MSM and heterosexual.

In 1993, The New York Times wrote an article about a dentist in Florida who infected six of his patients. It had become an unsolved mystery as no one is sure how it happened. It is thought he might have accidently cut himself or poked his finger with a needle and infected the patients that way. The articles went on to discuss whether AIDS testing should be mandated for all healthcare professionals. Some people viewed the dentist as being no better than a murder.

AIDS (Acquired immunodeficiency syndrome) is disease caused HIV (human immunodeficiency viruses). This research paper describes the evolution and origination of HIV and AIDS. There are two types of HIVs. These are called HIV-1 and HIV-2. HIVs result multiple cross species transmission from SIV (simian immunodeficiency viruses) that is viruses that infects primates. HIV-1 comes from SIV from chimpanzees whereas HIV-2 comes from sooty mangabeys. HIV-1 has four sub groups these includes M, N, O, and P. Each of groups has resulted from independent cross-species transmission event. Group M is the most virulent, and it is the first to be discovered. HIV-2 has groups that ranges from A to H. SIV are infecting West Africa primates. This fact is based on the first pandemic HIV-1 has emerged in colonial West African, and most researchers have sampled primates from this region only. Newly emerged SIVs are resulted from multiple cross species transmission and recombination. The cross species transmission occurs from non-humans to humans through eating bushmeat. The cross transmission influenced by host restriction factors, but HIVs were able to pass this barriers. Most SIV are non-pathogenic to the host; however, there is some evidence that some are pathogenic to their host. The age of the virus determined by using molecular clock method. Other studies have estimated the evolutionary timescale with same age as
