Following the discovery, the first test for HIV was approved in 1985. Over the years, medications to combat the virus were developed as well as medicine to prevent infection all without a successful result. HIV/AIDS remain one of the greatest health and social problem threatening humanity. The basic biology of the virus from inside out include RNA which contains all of its genetic information, a key enzymes it uses to replicates (reverse transcriptase) and a binding proteins that allow it to binds to human cell, (USAID,2007).…
Vaccines work by stimulating our immune system to produce antibodies without actually infecting us with the disease.…
There is currently no publicly available HIV vaccine or cure for HIV or AIDS. The only known methods of prevention are based on avoiding exposure to the virus or, failing that, an antiretroviral treatment directly after a highly significant exposure, called post-exposure prophylaxis (PEP). PEP has a very demanding four week schedule of dosage. It also has very unpleasant side effects including diarrhea, malaise, nausea and fatigue.…
Robert Gallo and his colleagues had isolated the retrovirus HTLV-III and a diagnostic blood test was well into development. Less than a year later, FDA licenses HIV blood tests for sale (CDC).This was a momentous achievement; in such a short time the scientific community had persevered against this faceless, mysterious threat and were making progress. Prior to this, the scientific community saw viral infections as impossible to treat, and not serious enough to finance thorough research for a cure (Zurger). “Immunologists now have a far better understanding of the primary immune cells called T-lymphocytes that the virus particularly strikes [...] and the complex links between cancer, immunity and infection have also been cemented by findings in H.I.V.-infected people” (Zurger). The field of retrovirology was born; scientists were able to gain from the massive inflow of data collected over the next years how retroviruses alter the DNA of their host cells, how they evade immune detection, and were able to draw parallels between the spread of cancer and and spread of HIV infection. This provided the necessary context for inferences on the bases for RNA genetic code, sparking research that was able to assess and explain the function of reverse transcriptase (Broder). In 1985, the first treatment for HIV/AIDS, Zidovudine (commonly referred to as AZT), was sold and several wellness programs…
Human Immunodeficiency Virus (HIV) is a virus that affects the human immune system and leads to a stat makes the patient unable to fight against diseases and so opportunistic diseases such Tuberculosis and others affect the individual (Worthington et al., 2010). HIV/AIDS was first realized in 1981 by the Center for Disease Control and Prevention and is believed to have originated from West-Central Africa. HIV/AIDS has been termed as one of the greatest causes of death in the global society (Gibbs, 2010). The virus is spread when body fluids of a victim gets into contact with the body fluids of another person. Due to the nature of the disease, even unsuspecting individuals such as patients undergoing blood transfusion, unborn babies and others can become victims. HIV is primarily spread through sexual intercourse without any form of protection (Ford et al., 2007; Gardezi et al., 2008).…
Vaccines today work the same way. They are developed to be less harmful to a person then the actual disease. Often a dead virus or part of the virus is used to make the vaccination that is injected into an individual. This vaccination shot causes a child’s immune system to develop a future defense against the disease. They are now immunized against certain viruses or…
HIV is the human immunodeficiency virus that causes AIDS. A member of a group of viruses called retroviruses, HIV infects human cells and uses the energy and nutrients provided by those cells to grow and reproduce. Most people are not aware of even carrying the disease. In order for you to be clear of this disease always make sure you maintain yourself well and stay protected.…
“HIV is the virus that causes AIDS” (2010). The virus weakens the body’s defense system, this makes it hard on the body to fight off other health problems and as time goes by the body becomes less able to fight off diseases. In the United States there was one in four new cases, which women account for and two in three are African American women who got HIV from unprotected sex with a man.…
It was the eighth-most common cause of death, behind diabetes (just under 80,000 deaths). It’s also the only cause of death in the top 10 that could be significantly reduced by a vaccine. Lowering risks of heart disease, cancer or Alzheimer’s are much, much harder to do. In 1995, the worst year of the AIDS epidemic in the United States, fewer than 51,000 people died of it. In 2014, just over 6,700 deaths were attributable directly to H.I.V.…
The human immunodeficiency virus (HIV) is a virus that attacks the body by weakening the immune system. Once people get infected by the virus it remains in the body for life; some of the symptoms that can be expected are diarrhea, fever, headache, mouth soar, night sweat, and swollen lymph nodes, followed more serious illness with progression of the virus. However, many people reported having no symptoms and don’t even know they have the virus until they are diagnosed. After the patient is diagnose the patient can lived for a number of years before experiencing severe health issues, during this period the person with the disease could transfer the virus from one person to another. The virus is transfer from one…
Viruses have been co involving with us for millions of year that is why it is so important to vaccine children. To understand the importance of vaccines we must understand immunity. Our immune system depends on the white blood cells of the body and it is our best defense against foreign pathogens and diseases. Immune cells are on the lookout for specific germs and move in on the germs immediately with their antibodies to remove the germs. After antibodies remove the germs, memory cells are left behind to memorize the germs for future defense system.…
Human immunodeficiency Virus also known as HIV is a sexually transmitted disease. It attacks your body's immune system. The virus destroys CD4 cells, which help your body fight diseases. HIV damages your immune system and it leads to acquired immune deficiency syndrome also known as AIDS. AIDS is the final stage in HIV, and it’s a disease where severe loss of the body's cellular immunity occurs. The disease lowers the resistance to infection and malignancy. Anyone can get HIV/AIDS. Men, women, and children, of all different races and descents can get infected with the virus. People who are gay or straight can also be infected with HIV/AIDS. There is currently no cure for HIV/AIDS. HIV treatments may reduce the amount of HIV in your blood. Treatments may also help to increase the number of CD4 cells in your blood which help fight off other infections. Patients who go through treatments for the virus must stay on continuous HIV therapy to control infection and decrease HIV related illnesses. Many studies and researchers are looking for cures.…
Vaccines work well with a 90-100 percent success rate. Tobias been argued that with besser hygiene and better sanitation the disease would go away , which is not true because the germs causing the disease would still be around . The vaccines need to be approved by the FDA and undergo extensive research be fore being used on humans.children should get vaccinated at two months, a second dose at four months and another dose at four to six years. Adults should get vaccinated at a first done anytime, a second one to two months later a nd a third dose six to twelve moth later. Advantages are that vaccines help to deacrease the spread of disease , the chance of falling I'll is far greater than that of getting a side effect. Getting a vaccine is cheaper thatbtreatong someone who is ill.disadvanges are that some people may have very bad reactions tovthe vaccines . Some parents think the MMR vaccines for measles mumps and tubella may cause autism in children so therefore won't take the risk. Ethicall issues inclise that some cultures believe that putting foreign substancesninto your body Mattake you less holy. Testing vaccines on vaulrnable populations such a children is unethical.the test in of the HIV vaccine may have a risk to the trial participant because of the stigma attached to…
Vaccines were invented in 1796 by Edward Jenner. It was more primitive than what we are used to today. In 1796 smallpox was still a big problem and Jenner noticed that milkmaids infected with the cowpox virus were immune to the smallpox virus as their body had already been familiar to the less potent virus and was able to fight the stronger virus with ease. So he decided to take infected pus of a milkmaid with the cowpox virus and give it to a eight year old boy to see if he would be immune to the smallpox virus. Sure enough when brought into a room with the smallpox virus he had not caught it and Jenner knew he made a breakthrough. However there has been turbulence when vaccines were newly being made, for example if they use a weaker live virus but not make it weak enough the person infected could catch the virus and become sick.…
It’s common knowledge all over the world that HIV infection is the leading cause of death. “Human immunodeficiency virus HIV and AIDS remain the leading causes of illness and death in the United States. As of December 2004, an estimated 944,306 persons had received a diagnosis of AIDS, and of these 529,113 (56%) had died” (Center for Disease Control, 2010). “Approximately 40,000 new cases of HIV infection occur each year and 40 million people worldwide are now living with HIV” (Falvo, 2010, pg. 318). Everyone knows, or should be aware that there’s no way to restore their damaged immune system, and no cure for HIV, nor for AIDS. Advances in medical systems today have shown improved life expectancy.…
