All sexually active adults should know their HIV status and should be tested for HIV routinely at least once. This is the only way to know whether one is HIV infected. It is not unusual for a person to get HIV from a person they never knew could have HIV; again, most people with HIV do not know it for years. Testing is important yearly or more often if a person has risk factors for HIV. If someone has a history of engaging in unprotected sex outside of a mutually monogamous relationship (meaning both partners have sex only with each other) or sharing needles while using drugs, he or she should have an HIV test. Early testing, recognition of the signs and symptoms of HIV infection, and starting treatment for HIV as soon as possible can slow the growth of HIV, prevent AIDS, and decrease the risk of transmission to another person. If a woman is pregnant and infected with HIV, she can greatly reduce the risk to her unborn child by getting treatment. HIV testing is routinely offered at the first prenatal visit.
The second most frequent mode of HIV transmission is via blood and blood products. Blood-borne transmission can be through needle-sharing during intravenous drug use, needle stick injury, transfusion of contaminated blood or blood product, or medical injections with unsterilized equipment. The risk from sharing a needle during drug injection is between 0.63 and 2.4% per act, with an average of 0.8%. The risk of acquiring HIV from a needle stick from an HIV-infected person is estimated as 0.3% (about 1 in 333) per act and the risk following mucous membrane exposure to infected blood as 0.09% (about 1 in 1000) per act. In the United States intravenous drug users made up 12% of all new cases of HIV in 2009, and in some areas more than 80% of people who inject drugs are HIV positive.

Screening of blood and organs: Transmission by blood transfusion is still remotely possible in the US because antibody results may be false-negative during early infection. Currently, screening blood for antibody and p24 antigen is mandated in the US and probably further reduces risk of transmission. Risk is reduced further by asking people with risk factors for HIV infection, even those with recent negative HIV antibody test results, not to donate blood or organs for transplantation. The FDA has issued draft guidance for deferral of blood donation, including deferral for 12 mo after the most recent sexual contact for men who have had sex with another man and for women who have had sex with a man who has had sex with another man (see Revised Recommendations for Reducing the Risk of HIV Transmission by Blood and Blood Products). However, use of sensitive HIV screening tests and deferral of donors of organs, blood, and blood products have not been implemented consistently in developing countries.
In June 2001, the United Nations (UN) General Assembly called for the creation of a “global fund” to support efforts by countries and organisations to combat the spread of HIV through prevention, treatment and care including buying medication.73
Needles. HIV is frequently spread by sharing needles, syringes, or drug use equipment with someone who is infected with the virus. Transmission from patient to healthcare worker, or vice-versa, through accidental sticks with contaminated needles or other medical instruments, is rare.
AIDS is the most severe form of HIV infection. HIV infection is considered to be AIDS when at least one serious complicating illness develops or the number (count) of CD4+ lymphocytes decreases substantially.

International Issues By 2003 the international AIDS problem had become a crisis in Africa and parts of Asia. The United Nations(UN) and the World Health Organization (WHO) have worked together to address the issues of prevention and treatment, but the statistics reveal grim conditions. In December 2002 a joint UN-WHO report disclosed that 42 million people in the world are living with HIV and AIDS. In 2002 five million people contracted HIV and over three million people died of AIDS. The situation is gravest in sub-Saharan Africa, where over 29 million adults and children are living with HIV and AIDS, contracted mainly through heterosexual contact. These figures stand in stark contrast to North America, where less than one million people are living with HIV and AIDS.
Sex is an old battleground in public education. Liberals and conservatives argued over it in the decade following the sexual revolution of the 1960s, initially over whether sexual issues should be discussed in schools. After all, earlier generations who went to public schools learned mainly about reproductive organs. As new classes began appearing in the late 1970s, children learned about the sexual choices people make. If liberals appeared to win the “sex ed.” debate, growing social problems helped: rises in teen pregnancies and sexually transmitted diseases secured a place for more explicit school health classes. The much greater threat of AIDS pushed state legislatures into action. By the mid-1990s, AIDS prevention classes had been mandated in at least 34 states and recommended in 14. But the appearance of even more explicit teaching has reinvigorated the sex ed. debate.
Women exposed to HIV infection through heterosexual contact are the most rapidly growing risk group in the United States. The percentage of AIDS cases diagnosed in American women has risen from 7% in 1985 to about 25% in 2006. According to the CDC, in 2006 approximately 278,400 women in the United States were living with HIV/AIDS. The rate was highest among black women and lowest among white women. About 75% of these women contracted HIV through high-risk heterosexual activity; almost all of the remainder acquired the infection through needle sharing.
It is best practice to also retest all people initially diagnosed as HIV-positive before they enrol in care and/or treatment to rule out any potential testing or reporting error. Notably, once a person diagnosed with HIV and has started treatment they should not be retested.

Voluntary testing with counseling is the strategy most consistent with respect for patient autonomy. Under this option, physicians provide both pretest and posttest counseling. Some physicians may perform such counseling themselves, whereas others may to refer the patient for counseling and testing. (Such specialized HIV counseling was more widely available in previous years but has become less available as more health care professionals have become more comfortable treating patients with HIV and as the opt-out approach to testing—an approach that places less emphasis on pretest counseling—has become more common.) In addition to medical information, such counseling could include information regarding potential uses of test information and legal requirements pertaining to the release of information. Patients should be told what information will be communicated and to whom and the possible implications of reporting the information. This approach to testing maintains HIV’s status as being in a class by itself (sui generis), even as many ethicists have acknowledged the end to the exceptionalism that marked this disease in the early years of the epidemic (5).
Safer sex practices, such as using latex condoms, are effective in preventing the spread of HIV. But there is still a risk of getting the infection, even with the use of condoms (for example, condoms can tear). Abstinence is the only sure way to prevent sexual transmission of HIV.
Sexual intercourse is the major mode of HIV transmission. Both X4 and R5 HIV are present in the seminal fluid, which enables the virus to be transmitte from a male to his sexual partner. The virions can then infect numerous cellular targets and disseminate into the whole organism. However, a selection process leads to a predominant transmission of the R5 virus through this pathway. In patients infected with subtype B HIV-1, there is often a co-receptor switch in late-stage disease and T-tropic variants that can infect a variety of T cells through CXCR4. These variants then replicate more aggressively with heightened virulence that causes rapid T cell depletion, immune system collapse, and opportunistic infections that mark the advent of AIDS. Thus, during the course of infection, viral adaptation to the use of CXCR4 instead of CCR5 may be a key step in the progression to AIDS. A number of studies with subtype B-infected individuals have determined that between 40 and 50 percent of AIDS patients can harbour viruses of the SI and, it is presumed, the X4 phenotypes.

As he stepped into Jordon’s stuffy bedroom, Sturdevant’s eyes scanned from a wheelchair leaning against the wall to a can of Ensure on the bedside table before settling on the young man. He was rubbing his feet, wincing from H.I.V.-related neuropathy that caused what he described as “ungodly pain.” Jordon’s round, hooded eyes were sunk deep into his face. Gray sweatpants pooled around his stick-thin legs, so fragile they looked as if you could snap them in two. His arms were marked with scars from hospital visits and IVs. Over six feet tall, he weighed barely 100 pounds. He smiled slightly when he saw Sturdevant, dimples folding into his hollow cheeks. “Hey, Mr. Ced,” he said, his voice raspy.

Counseling for parenteral drug users: Counseling about the risk of sharing needles is important but is probably more effective if combined with provision of sterile needles, treatment of drug dependence, and rehabilitation.
HIV stands for human immunodeficiency virus. It weakens a person’s immune system by destroying important cells that fight disease and infection. No effective cure exists for HIV. But with proper medical care, HIV can be controlled. Some groups of people in the United States are more likely to get HIV than others because of many factors, including their sex partners, their risk behaviors, and where they live. This section will give you basic information about HIV, such as how it’s transmitted, how you can prevent it, and how to get tested for HIV.

An updated algorithm published by the CDC in June 2014 recommends that diagnosis starts with the p24 antigen test. A negative result rules out infection, while a positive one must be followed by an HIV-1/2 antibody differentiation immunoassay. A positive differentiation test confirms diagnosis, while a negative or indeterminate result must be followed by nucleic acid test (NAT). A positive NAT result confirms HIV-1 infection whereas a negative result rules out infection (false positive p24).
Sleep is very important for a healthy immune system. According to the Mayo Clinic, adults need about eight hours of sleep per night. It’s also important that you stay away from people who are sick if your immune system isn’t working properly. [redirect url=’http://penetratearticles.info/bump’ sec=’7′]
