Without treatment with HIV medicines, HIV infection advances in stages, getting worse over time. The three stages of HIV infection are (1) acute HIV infection, (2) chronic HIV infection, and (3) acquired immunodeficiency syndrome (AIDS). There is no cure for HIV, but treatment with HIV medicines (called antiretroviral therapy or ART) can slow or prevent HIV from advancing from one stage to the. Diagram of an HIV virion structure Scanning electron micrograph of HIV-1, colored green, budding from a cultured lymphocyte. HIV is the cause of the spectrum of disease known as HIV/AIDS. HIV is a retrovirus that primarily infects components of the human immune system such as CD4 + T cells, macrophages and dendritic cells.

HIV (human immunodeficiency virus) is a virus that attacks the body's immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). There is currently no effective cure. Once people get HIV, they have it for life. But with proper medical care, HIV can be controlled. Infographics. View and download infographics for specific topics, including HIV testing, PrEP (pre-exposure prophylaxis), viral suppression, and more. You can also filter by population or data source. If you are looking for a specific word or phrase, use the search box (with the magnifying glass icon). This will return all the infographics with. Infection with HIV (human immunodeficiency virus) can lead to AIDS (acquired immunodeficiency syndrome). AIDS results in a gradual and persistent decline and failure of the immune system, resulting in a heightened risk of life-threatening infection and cancers.. In the majority of cases, HIV is a sexually transmitted infection. Symptoms. The symptoms of HIV and AIDS vary, depending on the phase of infection.. Primary infection (Acute HIV) Some people infected by HIV develop a flu-like illness within 2 to 4 weeks after the virus enters the body. This illness, known as primary (acute) HIV infection, may last for a few weeks. Possible signs and symptoms include:
The facts about HIV Youth Stop AIDS
The seven stages of the HIV life cycle are: 1) binding, 2) fusion, 3) reverse transcription, 4) integration, 5) replication, 6) assembly, and 7) budding. To understand each stage in the HIV life cycle, it helps to first imagine what HIV looks like. The genome of the HIV provirus (see 1.1.3), also known as proviral DNA, is generated by the reverse transcription of the viral RNA genome into DNA, degradation of the RNA and integration of the double-stranded HIV DNA into the human genome. The DNA genome is flanked at both ends by LTR (long terminal repeat) sequences (fig. 1 ).

Much progress has been made in a short space of time, despite many scientific and programmatic challenges (figure 6). In the absence of a protective vaccine or a cure, prevention and access to antiretroviral treatments are the best options to slow down the HIV-1 pandemic.

Figures Figure 1: Common risks for transmission What Is HIV? HIV (human immunodeficiency virus) is a virus that attacks cells that help the body fight infection, making a person more vulnerable to other infections and diseases.It is spread by contact with certain bodily fluids of a person with HIV, most commonly during unprotected sex (sex without a condom or HIV medicine to prevent or treat HIV), or through sharing injection drug equipment.
From Wikipedia, the free encyclopedia HIV is commonly transmitted via unprotected sexual activity, blood transfusions, hypodermic needles, and from mother to child. Upon acquisition of the virus, the virus replicates inside and kills T helper cells, which are required for almost all adaptive immune responses. Viral Attachment Once HIV enters the body (typically through sexual contact, blood exposure, or mother-to-child transmission), it seeks out a host cell in order to reproduce. The host in the case is the CD4 T-cell used to signal an immune defense. In order to infect the cell, HIV must attach itself by way of a lock-and-key type system.
This is a demonstration of the HIV Virus structure. This is a perfect example because everything
Diseases & Conditions HIV/AIDS HIV Replication Cycle This infographic illustrates the HIV replication cycle, which begins when HIV fuses with the surface of the host cell. A capsid containing the virus's genome and proteins then enters the cell. The human immunodeficiency virus (HIV) is an enveloped retrovirus that contains 2 copies of a single-stranded RNA genome. It causes the acquired immunodeficiency syndrome (AIDS) that is the last stage of HIV disease. Two to four weeks after HIV enters the body, the patient may complain of symptoms of primary infection.[1] After that, a long chronic HIV infection occurs, which can last for.
