There are many different factors to think about when learning about HIV. It is important to start from the beginning and look at the development of HIV and how it jumped from chimps to humans in the early 1900s. It is also important to think about how it is transmitted between humans and why HIV became so rampant in America during the 1980s. Lastly it is important to look at both the processes of the HIV life cycle, along with HIV evading the immune system.
There are multiple different theories about the origin of HIV and how it jumped to humans. One of which is called the ‘cut hunter theory.’ This theory begins about one million years ago in Cameroon, with a chimp eating both a red cap mangabey and a spot nosed guenon. The mingling of the

Within the immune system, there are four important parts within the blood: platelets (form blood clots), red blood cells (transfer oxygen), white blood cells (fight infection), and plasma (surrounds blood). Starting with white blood cells—there are two different types: phagocytes and lymphocytes. Within phagocytes, there are also dendritic cells and macrophages. Lymphocytes are located within the lymph nodes and include both T Cells (which mature in the thymus) and B Cells. Both of these cells come from bone marrow. It is also important to note that there are two different type of T cells: CD4 and CD8. After HIV enters the immune system, the first step is infection. This is the step where people can take medication to prevent the HIV from maturing. The second step is when the viruses and their proteins land on infected cells and stimulate the macrophages. Next, the interleukin 1 is released and the virus replicates itself within the T helper cell. After this, the interleukin 2 is released and the cytotoxic T cells activate and kill infected cells. B cells then activate as well, then multiply and release a multitude of antibodies that go on to kill either the virus, or the infected macrophages. Although with other viruses and bacterium, cells see the antibodies attached to a particle, and they go on to kill it—with HIV—the particle oftentimes doesn’t have enough receptors for the antibody to take an affective hold. It is important to note the three cells that can be infected by HIV: T helper cells, macrophages, and dendritic cells. If any of these cells are infected, the immune system process cannot continue. It is also important to talk about the dendritic cell. While oftentimes HIV reaches the dendritic cell through tears in the skin, it is also possible for HIV to reach the cell from within the body. The job of the dendritic cell is to catch viruses within the body, and bring them to the
This eliminates the infected cell" before it has time to multiply. (Alberts, B. 1970) 2. Your immune system is constantly working to fight off foreign invaders. The body recognizes its own cells from foreign cells by protein markers or antigens. As the B and T cells form the can tell the difference between your own cells and foreign cells.
As well as Preston’s point of view that AIDS also must be taken under considerations because the AIDS symptoms progress slowly, onset of the disease usually occurs in adulthood, and it might be asymptomatic that can be as lethal as the Ebola
If I was diagnosed with HIV, I would be in shock/disbelief, and I may ask to repeat the blood test, to make sure that the diagnosis is correct. HIV is going to make drastic changes in my life. My days would not be the same. I would worry about my husband and children, and be embarrassed to tell my relatives and friends. I would feel terrible about the whole situation, isolation, pain, suffering, and helplessness.
The virus had no cure yet, and there was research going on to see if it was possible to get its treatment. Similarly in the current world, humans protect themselves from contracting infectious diseases such as HIV or malaria. They apply all the preventive ways to curb the danger of contracting the diseases. In the film, Selena is seen to kill her fellow survivor Mark, who had been infected with the virus and Selena did not want to be infected. In the current setting, there are over one billion people in the world who are living with HIV/AIDS, and it does not have a cure.
There are four ways that you can catch HIV. The four ways are; Sexual intercourse (vaginal and anal),Oral sex (mouth-penis, mouth-vagina),Sharing injection needles, and Mother to Child. To continue,Mary fisher contracted HIV from her husband during marriage. Throughout Mary Fisher's speech she says that “It does not care whether you are Democrat or Republican. It does not ask whether you are black or white, male or female, gay or straight, young or old.”
Hello Professor and Classmates, As a human service professional I would have to intercede differently with a client who has a diagnosis of AIDS from a client who has been diagnosed as HIV positive for many reasons. HIV is a virus that gradually attacks the immune system, which is our body’s natural defense against illness. AIDS is a syndrome caused by the HIV virus. It is when a person’s immune system is too weak to fight off many infections.
The second theory used to explain the origin of primates is the visual predation hypothesis. This theory states that, the ability to move
The work of people being evil accusing people of crimes that was not attempted yet The salem witch trials all started in the year 1692. There was thousands of people was accused of witchcraft. And for others was accused of kidnapping little girls. twenty people died during the salem witch trials. Local people was almost everyday was getting harassed for them possessing witchcraft.
The Hunters Ed course taught me the necessary information and skills, to hunt safely and responsibly. The Hunters Ed course educates hunters on how to avoid accidents and be safe when hunting. Although this course is predominantly focused on hunting, the values, and skills can still be applied to other situations in life. In my essay, I will go over how hunters ed can be used in future life situations. One of the ways Hunters Ed can be applied in the future is the preservation of wildlife and nature.
The demise of the hunter gather society is a result of the beginning of an ice age and the need for a reliable food source. In turn, they completely reinvented basic means for obtaining food through the development of agriculture, refocusing energies to innovations and cultural development. The methods that hunter gather societies used to track food was not time efficient as stated in the Guns, Germs, and Steel video with Jared Diamond. It is not productive to track down each animal, spot the quarry, and use primitive bows and arrows for it is not guaranteed capture.
People create stereotypes based on race, gender, age, and even a person’s job or hobbies. There are many stereotypes that people have towards hunters. People have many different ideas and opinions of what a hunter looks like or acts like. Many of these stereotypes refer to the look or attitude of a hunter. Many of these thoughts may be true to a certain extent but do not necessarily accurately represent the modern hunter.
OUTBREAK Questions: 1. When and where was the Motaba virus first discovered, and what did the government do in order to try and destroy it? The Motaba virus was first discovered in an Motaba River Valley, Zaire in a mercenary camp in 1967. The government sent two soldiers to bomb the camp and try to destroy it, so that the disease would not spread.
A virus is considered non- living but shows two things of living, they are made up of protein and genetic material. Viruses are very small, they can be seen with a microscope, and invade living cells. Since viruses don’t consist of cells, they have to depend on a host cell to help them make copies of their selves. When a virus enters a cell it uses that cells ATP to replicate.
A hunter’s life was never an easy one; not only were they raised and conditioned into the violent lifestyle, but they were coached to be willing to take their own lives if they were compromised. It was the golden rule, as far as hunters were concerned. If there was any chance of one of them becoming a danger to others they would be required, by the hunter’s laws, to prevent the disease from spreading; such as werewolf bites. For many, there was no option with what they had to do, it was incredibly well ingrained in them to believe that they were doing themselves a mercy, as well as other hunters and possible victims. However, this was not the case when a young huntress found herself in a distressing situation.
