Such testing is confidential and often free of charge. The current 4th-generation combination screening test tests for two things that suggest HIV infection:. Antibodies to HIV. Antibodies are proteins produced by the immune system to help defend the body against a particular attack, such as that by HIV. Antigens are foreign substances that can trigger an immune response. The body takes several weeks to produce enough antibodies to be detected by the test, so results of the antibody test are negative during the first few weeks after the virus enters the body.
However, results of the p24 antigen test can be positive as early as 2 weeks after the initial infection. The combination tests can be done quickly by a laboratory. Also, a version of these tests can be done in a doctor's office or clinic called bedside testing. The newer combination screening test is quicker and less complex than older screening tests, which use enzyme-linked immunosorbent assay ELISA to detect HIV antibodies and then confirm positive results using a separate, more accurate, specific test such as the Western blot test.
Other, older rapid bedside tests are also available. These tests can be done using a sample of blood or saliva.
If results of these rapid screening tests are positive, they are confirmed by ELISA with or without Western blot or by repetition of one or more other rapid tests. If people at low risk have a negative test result, the screening test is not repeated unless their risk status changes.
With good and consistent care, you can live a long and healthy life. The virus pushes buds through the membrane of the cell, wrapping itself in a fragment of the cell membrane and pinching off from the infected cell. The next morning, I had another article to write. This provided morning sessions in the sanatoria as part of an eight-week program. You might also like Daryll Rowe.
If people at the highest risk have a negative test result especially if they are sexually active, have several sex partners, or do not practice safe sex , testing should be repeated every 6 to 12 months. HIV RNA tests often use techniques to produce many copies of an organism's genetic material called nucleic acid amplification. If the CD4 count is low, people are more likely to develop serious infections and other complications of HIV such as certain cancers. Viral load helps predict how fast the CD4 count is likely to decrease over the next few years.
With successful treatment, the viral load falls to very low levels within weeks, and the CD4 count begins a slow recovery toward normal levels. AIDS is diagnosed when the CD4 count falls below cells per microliter of blood or when extreme wasting or certain serious opportunistic infections or cancers develop. Various tests may be done to check for conditions that can accompany HIV infection. These tests include the following:.
Bone marrow aspiration and biopsy: To check for low blood cell counts including anemia , which may be due to lymphomas, cancers, and opportunistic infections. Computed tomography CT with a contrast agent or magnetic resonance imaging MRI : To check for damage to the brain or spinal cord. However, treating people who have HIV infection reduces the risk of their transmitting the infection to other people. However, the measures required for prevention—sexual abstinence or consistent condom use and access to clean needles—are sometimes personally or socially unpopular.
Many people have difficulty changing their addictive or sexual behaviors, so they continue to put themselves at risk of HIV infection. Also, safe sex practices are not foolproof. For example, condoms can leak or break. Use a latex condom for each act of intercourse with an infected partner or a partner whose HIV status is unknown vaginal spermicides and sponges do not protect against HIV infection.
For men, get circumcised circumcision reduces a man's risk of being infected with HIV during vaginal sex with an infected woman. For newly monogamous couples, get tested for HIV infection and other sexually transmitted diseases STDs before engaging in unprotected sexual intercourse. Wear rubber gloves preferably latex when touching body fluids of a person who might be infected with HIV.
If accidentally exposed to fluids containing HIV for example, after a needlestick , seek treatment with antiretroviral drugs to prevent infection.
Condoms made of latex provide good protection against HIV as well as other common sexually transmitted diseases , but they are not foolproof. Oil-based lubricants such as petroleum jelly should not be used because they may dissolve latex, reducing the condom's effectiveness.
Other measures can help. For men, circumcision, an inexpensive, safe procedure, reduces the risk of becoming infected during vaginal intercourse with an infected woman by about half.
Whether circumcision reduces the risk of HIV infection in other circumstances is unclear. Because circumcision provides only partial protection against HIV infection, people should also use other measures to prevent HIV infection. For example, if either partner has a sexually transmitted disease or HIV infection, it should be treated, and condoms should be used correctly and consistently. People who are likely to come into contact with blood or other body fluids at their job should wear protective latex gloves, masks, and eye shields. These precautions apply to body fluids from all people, not just those from people with HIV, and are thus called universal precautions.
Universal precautions are taken for two reasons:. Viruses that cause other serious disorders such as hepatitis B and C can be transmitted by body fluids. Surfaces contaminated with HIV can easily be cleaned and disinfected because HIV is inactivated by heat and by common disinfectants such as hydrogen peroxide and alcohol. Because HIV is not transmitted through the air or by casual contact such as touching, holding, or dry kissing , hospitals and clinics do not isolate HIV-infected people unless they have another contagious infection.
In the United States, the following have almost eliminated transmission of HIV infection by organ transplantation or blood transfusion:. Risk is reduced further by asking people with risk factors for HIV infection, regardless of their test results for HIV, not to donate blood or organs for transplantation.
However, developing countries have not consistently used sensitive HIV screening tests and have not restricted donors. Consequently, transmission by these routes is still a problem in these countries. The following can help prevent HIV transmission from mother to newborn :. If they are infected, treating them with antiretroviral drugs during pregnancy and labor treatment during labor is especially important. After birth, treating the newborn with zidovudine , given intravenously, for 6 weeks.
Such preventive treatment is called preexposure prophylaxis PrEP. However, PrEP is expensive and is effective only if people take the drug every day. Thus, PrEP is recommended only for people who have a very high risk of becoming infected, such as people who have a partner who is infected with HIV. PrEP may also be recommended for people who engage in high-risk sexual activities, such as the following:.
Heterosexual men and women who do not regularly use condoms during sex with partners whose HIV status is unknown and who are at increased risk of HIV infection.
People who use PrEP still need to use other methods to prevent HIV infection, including consistent use of condoms and not sharing needles to inject drugs. People who have been exposed to HIV from a blood splash, needlestick, or sexual contact may reduce the chance of infection by taking antiretroviral drugs for 4 weeks. These drugs are more effective when they are started as soon as possible after the exposure.
Taking two or more drugs is currently recommended. Doctors and the person who was exposed typically decide together whether to use these preventive drugs. They base the decision on the estimated risk of infection and the possible side effects of the drugs. If they do not know whether the source is infected with HIV, they consider how likely the source is to be infected. However, even when the source of the exposure is known to be infected with HIV, the risk of infection after exposure varies, depending on the type of exposure. For example, risk from a blood splash is less than that from a needlestick.
People with HIV infection should have the following vaccinations for more information, see CDC immunization recommendations :. Influenza vaccine every year.
Hepatitis B vaccine if they have not had the vaccine before or have not completed the series of 3 vaccinations. Hepatitis A vaccine if they are at increased risk of or desire protection from hepatitis A. Human papillomavirus HPV vaccine to prevent HPV-related cervical and anal cancers given to females and males at the recommended ages. Meningococcal vaccine if adults have not had the vaccine before doses are given at least 2 months apart.
Tetanus-diphtheria vaccine Td with a booster every 10 years if people have not previously received the tetanus-diphtheria-pertussis vaccine [Tdap], Tdap is substituted for one Td booster. The herpes zoster vaccine may be useful. However, the original live-attenuated zoster vaccine is not given in people with a weakened immune system and if the CD4 count is below cells per microliter of blood. However, recommendations regarding use of the newer recombinant zoster vaccine in people with HIV have not yet been made.
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. Research has shown that people who are promptly treated with antiretroviral drugs are less likely to develop AIDS-related complications and to die of them. Treatment cannot eliminate the virus from the body, although the HIV level often decreases so much that it cannot be detected in blood or other fluids or tissues.
The goals of treatment are. Thus, people need to take antiretroviral drugs for their lifetime. Taking the drugs as directed for a life time is demanding. Some people skip doses or stop taking the drugs for a time called a drug holiday. These practices are dangerous because they enable HIV to develop resistance to the drugs.
Because taking HIV drugs irregularly often leads to drug resistance, health care practitioners try to make sure that people are both willing and able to adhere to the treatment regimen. To simplify the drug schedule and to help people take the drugs as directed, doctors often prescribe treatment that combines two or more drugs in one tablet that can be taken only once a day. Exposure to HIV does not always lead to infection, and some people who have had repeated exposures over many years remain uninfected.
Moreover, many HIV-infected people remain well for more than a decade. A very few HIV-infected, untreated people have remained well for over 20 years. Why some people become ill so much sooner than others is not fully understood, but a number of genetic factors appear to influence both susceptibility to infection and progression to AIDS after infection. If infected people are not treated, AIDS develops in most of them.

This is an excellent book full of good sound advice that individuals can follow to help decrease some of the side effects of HIV/AIDS.
Generally, experts estimate that if untreated, people develop AIDS at the following rates:. However, with effective treatment, the HIV RNA level decreases to undetectable levels, CD4 counts increase dramatically, and people can continue to lead productive, active lives.
The risk of illness and death decreases but remains higher than that of people who are of similar age and who are not infected with HIV. However, if people cannot tolerate or take drugs consistently, HIV infection and immune deficiency progresses, causing serious symptoms and complications. Usually, HIV infection does not directly cause death. Instead, HIV infection leads to a substantial loss of weight wasting , opportunistic infections, cancers, and other disorders, which then lead to death. Cure has been thought to be impossible, although intensive research on how to eliminate all of the latent HIV from infected people continues.
Because death rarely occurs suddenly in people with AIDS, people usually have time to make plans for the kind of their health care they want if their condition worsens. Nonetheless, people should record such plans in a legal document early and should include clear instructions about the kind of care they want called advance directives. Other legal documents, including powers of attorney and wills, should be prepared.
These documents are particularly important for same-sex couples because they may wish to protect the assets and rights including visitation and decision-making of their partners. Near the end of life, many people have pain and other distressing symptoms such as agitation and usually lose their appetite. Hospice programs are particularly equipped to deal with such problems.
They can provide comprehensive support and care, which focuses on managing symptoms, helping dying people maintain their independence, and supporting their caregivers.
