Description - general:
Human immunodeficiency virus infection and acquired immunodeficiency syndrome (HIV/AIDS) is a disease (lentivirus) of the immune system caused by infection with human immunodeficiency virus. It is characterized by a short period of flu-like symptoms followed by a long period of little to no symptoms. As HIV progresses further eventually into AIDS, one’s chances of getting opportunistic infections and tumours that would not normally affect someone with a normally working immune system.
Description - cause:
HIV is transmitted from one person to another in numerous ways, sexual intercourse being the most common. Other methods of transmission include infected blood transfusion, mother to child during delivery when the mother is pregnant or through breastfeeding. Although it was previously thought that the virus was limited only to homosexual men this is not true and most transmissions today happen through heterosexual sex.
Description - system:
The main system being affected by the virus is the immune system however once the immune system is no longer rendered useful due to the virus, other infections and diseases such as cancer can begin to affect all the different systems.
Description - organs and cells:
HIV/AIDS does not affect any specific organ but the immune system as a whole. Once the virus weakens the immune system to a point where it no longer protects one against diseases, every organ can be affected by either an opportunistic infection or a tumour. A key specialized cell that is affected by HIV/AIDS is the CD4 cell or the t-cell. This cell helps humans protects themselves against very common but deadly diseases. The HIV virus attacks these cells and uses them to make more HIV cells. ...

...otested by many. While there are not many risks with HIV treatment there are many side effects that make it harder to commit to a full treatment. Some side effects include dry mouth, vivid dreams, anemia, insomnia and weight loss. Although side effects will appear it is important that one does not stop taking the drugs as the virus can develop drug resistance, and should instead talk with their doctor on a plan for further treatment. Although HIV treatment is very effective it does not always work amazingly. Reasons for this are because when the cells copy inside of a human they are not perfect and do not turn out to be the same every time. Some of these imperfect cells develop a resistance to the drugs administered. This can be avoided by taking another drug that helps prevent cells from developing a resistance to the other drugs however this does not always work.
It is crucial to understand that, unlike most transmissible diseases, AIDS/HIV is not transmitted through sneezing, coughing, eating or drinking from common utensils, or even being around an infected person. Casual contact with AIDS/HIV infected persons does not place others at risk. HIV/AIDS can be passed through unprotected sex with an infected person, sharing contaminated needles, from infected mother to baby during pregnancy, birth or breastfeeding, and through direct exposure to infected blood or blood
This virus searches for a new vulnerable host in order to survive and carry the disease to the next victim. The critical aspect around the spread of a virus is how drastically the reproduction process occurs. Without being controlled, the contamination throughout any species causes the spread to take place in a toxic way, “On day one, there were two people. And then, four, and then, sixteen. In three months, it’s a billion.
Different people define success in many different ways. What is considered success by one person may be viewed as failure by another person. Randy Shilts, a homosexual newspaper reporter / author, attempts to make fundamental changes in America’s opinion on AIDS. In Randy Shilts’s essay, "Talking AIDS to Death," he speaks of his experiences as an "AIDS celebrity." At the core of Shilts’s essay is the statement, "Never before have I succeeded so well; never before have I failed so miserably"(221). Shilts can see his accomplishments from two points of view- as a success and as a failure. Despite instant fame, Shilts is not satisfied with the effects his writings has on the general public. Shilts’s "success" and reasons for failure can both be considered when one decides whether or not his efforts were performed in vain.
Polio is a viral disease. It cripples thousands of people and infects even more every year. Even though millions are inoculated, and the polio disease has been successfully purged from hundreds of countries still thousands of people and developing countries are infected and still people are dying. According to the World Health Organization (WHO) polio affects the Central Nervous System, or CNS; by infesting the intestines and transmitting it into the nerves thought the blood vessels. There the virus spreads through the nerve cells to the brain stem or other motor units, while forever damaging the nerves.
Everyday researchers have proposed new methods of how to control the HIV virus from turning into AIDS. A combination of effective HIV medicines help stop the formation of new copies of HIV as it reproduces in your body. This technique helps to keep your CD-4 cell count up and your viral load down. CD-4 cells are one type of immune cells that assist to fight off the virus, the higher your count the stronger your immune system (Nakashima 77). Whereas, your viral load is a measure of HIV in your blood and your treatment goal is to have the lowest viral load possible. People with higher viral loads tend to progress to AIDS and become sick sooner than those with lower viral loads (Nakashima 80). Successful HIV medications can prevent other infections common with AIDS and can help you live longer.
According to the Public Health Agency of Canada HIV – the Human Immunodeficiency Virus - is a virus that attacks the immune system, resulting in a chronic, progressive illness that leaves people vulnerable to opportunistic infections and cancers. (Canada 2008) Essentially over time, when your body can no longer battle the virus it progresses into a disease know as Acquired Immunodeficiency Syndrome or AIDS. The transmition of HIV occurs when a person’s contaminated body fluids enter another individual. Unprotected sexual intercourse (vaginal, anal or oral), sharing needles, using unsterilized equipment for body modification, mother to infant transmition, as well as occupational exposure in health care are all ways HIV can be spread. HIV/AIDS as an illness is relatively new. The first reported case of AIDS in the world was in 1981, and a year later in Canada. Scientists all around the world are busy searching for a cure or vaccine to treat the millions of people internationally dying of HIV/AIDS.
HIV, also known as Human Immunodeficiency Virus, is a virus that attacks the body’s immune system. If left untreated, HIV reduces the number of CD4 cells in the body, which makes a person more likely to get infections or infection-related cancers. HIV can also lead to AIDS (acquired immunodeficiency syndrome), if it is not being treated (aids.gov). There is no effective cure for HIV, however with proper treatment and medical care, HIV can be controlled. In
Acquired Immune Deficiency Syndrome (AIDS) is a chronic, potentially life-threatening condition caused by the human immunodeficiency virus (HIV). AIDS weakens the immune system hampering the body’s defense mechanisms. AIDS is known to be a deadly disease, especially if it is not treated in a timely manner. AIDS and HIV is an epidemic that is increasing among the African American population with roots tracing back to Africa, AIDS and HIV needs greater exposure and more awareness within the African American community and in the homosexual community.
Human immunodeficiency virus (HIV) is a retro virus that causes AIDS. HIV is a virus that can only be contracted between human to human. HIV weakens your immune system because this virus is destroying cells that fight diseases and infection in your body. A virus can only produce itself by taking over a cell in the body of its h...
HIV is the human immunodeficiency virus; this virus can lead to acquired immune deficiency syndrome, or AIDS. According to Avert, 2.6 million people became infected with HIV in 2009, there are now an estimated 33.3 million people around the world who are living with HIV. HIV is transmitted by the exchange of bodily fluids via sharing contaminated syringes, from the infected mother to the child, and sexual contact. Contact with blood, semen, vaginal secretions, breast milk, or saliva that is contaminated with HIV, puts an individual at higher risk for contracting HIV. However, HIV cannot be transmitted by touch, coughing, or by bits from insect vectors.
Human Immunodeficiency Virus (HIV) is a virus that your body can’t get rid of. This virus sits in your body and attack your immune system and essential virus fighting cells. Acquired Immunodeficiency Syndrome (AIDS) is the final stage of HIV infection. At this point of HIV people have badly damaged immune systems, which put them at risk for other disease and infections.
for which no cure has yet been created. It is important to know however, that methods are currently available which can prevent the transfer of this virus, and even slow down its malicious effects. before they become fatal. It is equally important to know how to avoid getting the virus and also the symptoms in case you might run across them. They are all a lot.
Most people recently infected by the AIDS virus look and feel healthy. They may not show symptoms for several years, but the condition is eventually fatal. Even though one might not know that they have this deathly disease, and remain apparently healthy, they can still pass it along to others, and they then pass it on to others, etc, until an abundant amount of people are infected. Symptoms may include fever, fatigue, weight loss, skin rashes, a fungal infection of the mouth known as thrush, lack of resistance to infection, and swollen lymph nodes. HIV, the virus that causes AIDS, is transmitted through blood, semen, and vaginal fluid. The virus is usually transferred through sexual intercourse, the transfusion of virus-contaminated blood, or the sharing of HIV-contaminated intravenous needles. HIV cannot penetrate intact bodily surfaces, such as skin, and quickly perishes outside the human body. Consequently, AIDS is not spread by casual physical contact.
Acquired immune deficiency syndrome (AIDS) is a fatal physical condition that is caused by the human immunodeficiency virus (HIV). The virus damages the human body’s immune system, so that the body cannot protect itself from bacteria, viruses, and prions that cause diseases. With severely lowered defenses, AIDS patients die from common illnesses such as pneumonia, diarrhea, cold, and tuberculosis. The HIV virus does not directly attack its victim; the disease that patients suffer from after receiving the virus is what hurts and kills them.
The emergence of HIV/AIDS is viewed globally as one of the most serious health and developmental challenges our society faces today. Being a lentivirus, HIV slowly replicates over time, attacking and wearing down the human immune system subsequently leading to AIDS (Acquired Immunodeficiency Syndrome) at which point the affected individual is exposed to life threatening illnesses and eventual death. Despite the fact that a few instances of this disease have been accounted for in all parts of the world, a high rate of the aforementioned living with HIV are situated in either low or medium wage procuring nations. The Sub-Saharan region Africa is recognized as the geographic region most afflicted by the pandemic. In previous years, people living with HIV or at risk of getting infected did not have enough access to prevention, care and treatment neither were they properly sensitized about the disease. These days, awareness and accessibility to all the mentioned (preventive methods, care etc.) has risen dramatically due to several global responses to the epidemic. An estimated half of newly infected people are among those under age 25(The Global HIV/AIDS Epidemic). It hits hard as it has no visible symptoms and can go a long time without being diagnosed until one is tested or before it is too late to manage.
