Some enveloped RNA viruses can be produced in infected cells that continue growing and dividing without being killed. This probably involves some sort of intracellular regulation of viral growth. It is also possible for the DNA of some viruses to be incorporated into the host cell DNA, producing a carrier state. These are almost always retroviruses, which are called proviruses before and after integration of viral DNA into the host genome.
Two distinct species of HIV (HIV-1 and HIV-2) have been identified, and each is composed of multiple subtypes, or clades. All clades of HIV-1 tend to cause similar disease, but the global distribution of the clades differs. This may have implications on any future vaccine, as the B clade, which is predominant in the developed world (where the large pharmaceutical companies are located), is rarely found in the developing countries that are more severely affected by the disease.
The virus that causes AIDS, which is the most advanced stage of HIV infection. HIV is a retrovirus that occurs as two types: HIV-1 and HIV-2. Both types are transmitted through direct contact with HIV-infected body fluids, such as blood, semen, and genital secretions, or from an HIV-infected mother to her child during pregnancy, birth, or breastfeeding (through breast milk).
Founded in June 1987, South Side Help Center (SSHC) is purposed to help people of all ages embrace a lifestyle of prevention against mental, physical and social ills by providing positive, healthy alternatives so that community residents can lead productive lives. SSHC purpose and legacy is in serving the people of the community. We actualize our mission of “Providing people with positive and healthy alternatives” through many programs and services.

*PEP is optional and should be based on an individualized decision by the exposed person and the treating clinician. If PEP is offered and taken and the source is later determined to be HIV-negative, PEP should be stopped.
The HIV virion enters macrophages and CD4+ T cells by the adsorption of glycoproteins on its surface to receptors on the target cell followed by fusion of the viral envelope with the target cell membrane and the release of the HIV capsid into the cell.
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are commonly used in combination with NRTIs to help keep the virus from multiplying. Examples of NNRTIs are efavirenz (Sustiva), nevirapine (Viramune), delavirdine (Rescriptor), etravirine (Intelence), and rilpivirine (Edurant). Complete HIV treatment regimens that combine two NRTIs and one NNRTI in one pill taken once a day are available for convenience; these include Atripla (efavirenz/emtricitabine/tenofovir) and Complera (rilpivirine/emtricitabine/tenofovir).

Blood transmission — the risk of transmitting HIV through blood transfusion is extremely low in developed countries, thanks to meticulous screening and precautions. However, among people who inject drugs, sharing and reusing syringes contaminated with HIV-infected blood is extremely hazardous.
Through an approach of outreach, prevention and community information programs, AOC educates the public about HIV prevention while offering free and/or low-cost services to HIV+ individuals and their families.
If treatment fails, drug susceptibility (resistance) assays can determine the susceptibility of the dominant HIV strain to all available drugs. Genotypic and phenotypic assays are available and can help clinicians select a new regimen that should contain at least 2 and preferably 3 drugs to which the HIV strain is more susceptible. The dominant HIV strain in the blood of patients who are taken off antiretroviral therapy may revert over months to years to the wild-type (ie, susceptible) strain because the resistant mutants replicate more slowly and are replaced by the wild type. Thus, if patients have not been treated recently, the full extent of resistance may not be apparent through resistance testing, but when treatment resumes, strains with resistance mutations often reemerge from latency and again replace the wild-type HIV strain.
Treatment with antiretroviral drugs is recommended for almost all people with HIV infection because without treatment, HIV infection can lead to serious complications and because newer, less toxic drugs have been developed. For most people, early treatment has the best results.

Acquired Immune Deficiency Syndrome (AIDS) is an illness caused by HIV. AIDS is the stage of infection that occurs when your immune system is badly damaged and you become vulnerable to opportunistic infections. Without treatment, people who are living with AIDS typically survive about 3 years. There are medications, such as Non-nucleoside reverse transcriptase inhibitors […]

Body fluid exposure – exposure to HIV can be controlled by employing precautions to reduce the risk of exposure to contaminated blood. Healthcare workers should use barriers (gloves, masks, protective eyewear, shields, and gowns) in the appropriate circumstances. Frequent and thorough washing of the skin immediately after coming into contact with blood or other bodily fluids can reduce the chance of infection.
The time from HIV infection to the development of AIDS varies. Rarely, some individuals develop complications of HIV that define AIDS within one year, while others remain completely asymptomatic after as many as 20 years from the time of infection. However, in the absence of antiretroviral therapy, the time for progression from initial infection to AIDS is approximately eight to 10 years. The reason why people experience clinical progression of HIV at different rates remains an area of active research.
By January of 2000, the Centers for Disease Control reported that, for the first time since the beginning of the AIDS epidemic, the majority of new HIV/AIDS cases could be found among African American and Latino men.

At the present time, there is no cure for AIDS. It has proven to be a universally fatal illness. However, most patients survive many years following diagnosis. HAART has dramatically increased the time from diagnosis to death, and research continues in drug treatments and vaccine development.

…highest rate of HIV and AIDS infection of any country in Asia. Aggressive programs launched by the government to promote safe sex practices, however, have reduced the rate of increase in new HIV infections significantly. Nonetheless, AIDS has continued to claim the lives of several tens of thousands of people…
During this time, many scientists, researchers and government administrators were afraid to speak openly about condoms, needle exchange and L.G.B.T. issues for fear of reprisal and loss of funding. Community organizations became targets of anti-gay crusades, subjected to intense scrutiny, including exhaustive audits, by federal agencies. “It is no coincidence that new rates of H.I.V. infection among gay men, especially gay black men, began to spike sharply from 2000 on, because of an anti-science campaign that allowed for little or nothing to be done for a maligned community simply due to ideology and bigotry,” Millett said. “The hostile environment made funding effective H.I.V.-prevention programs, messages or research impossible for U.S. communities most impacted by H.I.V.”
A type of white blood cell. T-lymphocytes are part of the immune system and develop from stem cells in the bone marrow. They help protect the body from infection and may help fight cancer. Also called T cell and thymocyte.
In June 1995, the FDA approved the first protease inhibitor beginning a new era of highly active antiretroviral treatment (HAART). Once incorporated into clinical practice HAART brought about an immediate decline of between 60% and 80% in rates of AIDS-related deaths and hospitalisation in those countries which could afford it.62
In addition, each person’s blood is either Rh-positive or Rh-negative. It is important to know what to expect before, during, and after a blood transfusion, and the risk factors or complications of a blood transfusion. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
