Where does HIV/AIDS come from for staters?
Well the Aids Institute states “Scientists identified a type of chimpanzee in West Africa as the source of HIV infection in humans. They believe that the chimpanzee version of the immunodeficiency virus (called simian immunodeficiency virus or SIV) most likely was transmitted to humans and mutated into HIV when humans hunted these chimpanzees for meat and came into contact with their infected blood. Over decades, the virus slowly spread across Africa and later into other parts of the world.
The earliest known case of infection with HIV-1 in a human was detected in a blood sample collected in 1959 from a man in Kinshasa, Democratic Republic of the Congo. (How he became infected is not known.) Genetic analysis of this blood sample suggested that HIV-1 may have stemmed from a single virus in the late 1940s or early 1950s.
We know that the virus has existed in the United States since at least the mid- to late 1970s. From 1979–1981 rare types of pneumonia, cancer, and other illnesses were being reported by doctors in Los Angeles and New York among a number of male patients who had sex with other men. These were conditions not usually found in people with healthy immune systems.
In 1982 public health officials began to use the term “acquired immunodeficiency syndrome,” or AIDS, to describe the occurrences of opportunistic infections, Kaposi’s sarcoma (a kind of cancer), and Pneumocystis jirovecii pneumonia in previously healthy people. Formal tracking (surveillance) of AIDS cases began that year in the United States.
In 1983, scientists discovered the virus that causes AIDS. The virus was at first named HTLV-III/LAV (human T-cell lymphotropic virus-type III/lymphadenopathy-associated virus) by an international scientific committee. This name was later changed to HIV (human immunodeficiency virus).
For many years scientists theorized as to the origins of HIV and how it appeared in the human population, most believing that HIV originated in other primates. Then in 1999, an international team of researchers reported that they had discovered the origins of HIV-1, the predominant strain of HIV in the developed world. A subspecies of chimpanzees native to west equatorial Africa had been identified as the original source of the virus. The researchers believe that HIV-1 was introduced into the human population when hunters became exposed to infected blood.”
HIV is a lenti virus which is a subgroup of the retrovirus. For starters they affect the white blood cells (WBCs) in this sense:
We have types of WBC’s and one type is called CD4. That is the cell the HIV binds to when it gets in your blood stream. Another name for them is T-helper cells. CD4 cells are made in the spleen, lymph nodes, and thymus gland, which are part of the lymph or infection-fighting system. CD4 cells move throughout your body, helping to identify and destroy germs such as bacteria and viruses. Without going into specific medical terminology there is replication of this virus in the DNA and RNA killing out the normal white blood cell type of CD4 and other things like macrophages which are reproduced into CD4 cells with the virus with the body not knowing or able to detect this error in DNA and RNA of the CD4 white blood cells which ending line allows the immunity to go down. Remember the HIV virus binds to the surface of the CD4 cells. The virus entering CD4 cells now allows them to become a part of CD4 replicated cells regarding their make up due to changes made in the DNA and RNA cause the virus has invaded the bloodstream. As CD4 cells multiply to fight infection, they also make more copies of HIV now. Continuing to replicate, leading to a gradual decline of CD4 cells in decreasing that individuals immunity to infection.
There are two types of HIV have been characterized: HIV-1 and HIV-2. HIV-1 is the virus that was initially discovered and termed both LAV and HTLV-III. It is more virulent, more infective and is the cause of the majority of HIV infections globally. The lower infectivity of HIV-2 compared to HIV-1 implies that fewer of those exposed to HIV-2 will be infected per exposure. Because of its relatively poor capacity for transmission, HIV-2 is largely confined to West Africa.
The CD4 count measures the number of CD4 cells in a sample of your blood drawn by a needle from a vein in your arm. Along with other tests, the CD4 count helps tell how strong your immune system is. By knowing this when the blood test is done the CD4 helps the following for the doctor
-it indicates the stage of your HIV disease
-it guides the treatment
– it predicts how your disease may progress.
**Keeping your CD4 count high can reduce complications of HIV disease and extend your life.**
HIV is transmitted via the exchange of body fluids—such as pre-ejaculate fluid, semen, vaginal fluid secretions, blood, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.
Within a month or 2 of contracting HIV, about 40 to 90-percent of those afflicted suffer from flu-like symptoms including fever, fatigue, achy muscles, swollen lymph glands, sore throat, headache, skin rash, dry cough, nausea, rapid weight loss, night sweats, frequent yeast infections (for women), cold sores, and eventually, pneumonia. Luckily, many individuals who are diagnosed early can live a long, productive life with HIV thanks to a combination of highly active anti-retroviral drug therapy, which prevents to progression to AIDS.
So what is the answer to prevent this from happening by doing a few things:
-In safe sex from the front (through the vagina) or back (through the rectum-buttock); no matter what sex preference you are.
-When you use various sex partners get checked every 6 months to a year and have sex safely.
-The + HIV pt or now AIDS pt be compliant with the medications and RX the M.D. gives you if you choose to do so, unfortunately like many who chose to do unsafe sex in getting this or worse those getting it through blood with transfusions or needle sticks, or even sex partners who weren’t told their sex partner had it. There are the those who got this disease innocently with not doing unsafe sex but for that percentage it is much lower than those who caused this disease to go up higher in the USA and all over for being foolish. To all the people in the world let’s deal with this disease safely for yourselves and others around you. Let us all make a safer world for this is one small way which is greater than you may think.
