There is no cure for HIV infection. Before there were treatments for the virus, people with AIDS lived only for a couple of years. Fortunately, medications have substantially improved the outlook and survival rates. Prevention efforts have reduced HIV infection in young children and have the potential to limit new infections in other populations.

From a legal, ethical, and moral standpoint, they should warn any prospective sexual partner of their HIV positive status. They should not exchange body fluids during sexual activity and must use whatever preventative measures (such as a latex condom) will afford the partner the most protection.

Human immunodeficiency virus (HIV) associated cholangiopathy has been described in children.95 As in adults, the biliary abnormalities include irregularities of contour and caliber of the intrahepatic and extrahepatic ducts and papillary stenosis. The changes may result from concomitant infection with opportunistic organisms such as cytomegalovirus and Cryptosporidium parvum.

HIV is an enveloped retrovirus whose structure is shown in Fig. 11.22. Each virus particle, or virion, contains two copies of an RNA genome, which are transcribed into DNA in the infected cell and integrated into the host cell chromosome. The RNA transcripts produced from the integrated viral DNA serve both as mRNA to direct the synthesis of the viral proteins and later as the RNA genomes of new viral particles, which escape from the cell by budding from the plasma membrane, each in a membrane envelope. HIV belongs to a group of retroviruses called the lentiviruses, from the Latin lentus, meaning slow, because of the gradual course of the diseases that they cause. These viruses persist and continue to replicate for many years before causing overt signs of disease.
Health care professionals who fail to provide care to women who are infected with HIV because of personal practice preferences violate professional ethical standards. The public appropriately expects that health care practitioners will not discriminate based on diagnosis, provided that the patient’s care falls within their scope of practice. Physicians should demonstrate integrity, compassion, honesty, and empathy. Failure to provide health care to a woman solely because she is infected with HIV violates these fundamental characteristics. As with any other patient, it is acceptable, however, to refer women who are infected with HIV for care that the physician is not competent to provide or if care elsewhere would be more convenient or associated with decreased financial burden to the patient.
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.
Although epidemics are public crises, they begin with individuals. The rights of people who have AIDS and those who do not are often in contention and seldom more so than in private life. It is no surprise that people with HIV continue having sex, nor is it a surprise that this behavior is, usually, legal. Unfortunately, some do so without knowing they have the virus. Even more unfortunately, others do so in full knowledge that they are HIV-positive but without informing their partners. This dangerous behavior has opened one area of AIDS law that affects individuals: the legal duty to warn a partner before engaging in behavior that can transmit the infection. A similar duty was recognized by courts long before AIDS ever appeared, with regard to other sexually transmitted diseases.
These sub-epidemics each follow their own pattern, although there is some degree of interdependence. Early on, nearly all cases of HIV infection detected in the Western Hemisphere were in homosexual men, the spread of the disease to female partners of bisexual men with HIV infection gave rise to an increased rate among heterosexual persons.

Since the discovery of HIV and its link to AIDS, great strides have been made in understanding its biology and in developing effective treatments. The difficulty in dealing with HIV on a global scale is largely due to the fact that HIV infection is far more common in resource-poor countries.
A. there are no effective natural remedy for HIV. the medications are very hard ones that try to control the virus from spreading (cannot eliminate it though). no herbal remedy or nutrition change will do that.
According to the Centers for Disease Control and Prevention (CDC), from 2010-2015, the estimated rate of HIV infection diagnoses in all 50 US states decreased from 14.2 per 100,000 population in 2010 to 12.3 per 100,000 population in 2015.  In 2015, 39,513 individuals were diagnosed with HIV infection. From 2010 to 2014, the annual number of new HIV infection diagnoses decreased 9%.
Because HIV infection produces a wide range of symptoms, the CDC has compiled a list of conditions regarded as defining AIDS. The physician will use the CDC list to decide whether the patient falls into one of these three groups:
“Resistance occurs when the virus replicates in the presence of the drugs,” said Dr. Stephen Boswell, president and CEO of Boston’s Fenway Health, a healthcare organization that works with lesbian, gay, bisexual and transgender people. “Missed dosages lead to lower concentrations in the bloodstream and in the body, so the virus can become resistant and spread. So staying on your medications and not missing dosages is absolutely critical.”
Stein-Leventhal syndrome; polycystic ovary syndrome multiple ovarian cyst formation, with associated menstrual abnormalities, infertility, enlarged ovaries, insulin resistance, obesity, acne, evidence of masculinization (e.g. hirsuitism) and increased tendency to type 2 diabetes mellitus; responds to treatment with oral contraceptive pill and/or metformin
In addition to the concern for new opportunistic infections, pre-existing infections can reactivate and cause significant disease in people with AIDS. The most important example on a global scale is that of tuberculosis, as reactivated tuberculosis can cause symptomatic disease with lower levels of reactivation.
Nef also interacts with SH3 domains. The Vpu protein (p16) influences the release of new virus particles from infected cells. The ends of each strand of HIV RNA contain an RNA sequence called the long terminal repeat (LTR). Regions in the LTR act as switches to control production of new viruses and can be triggered by proteins from either HIV or the host cell. The Psi element is involved in viral genome packaging and recognized by Gag and Rev proteins. The SLIP element (TTTTTT) is involved in the frameshift in the Gag-Pol reading frame required to make functional Pol.
HIV is a preventable disease. Effective HIV prevention interventions have been proven to reduce HIV transmission. People who get tested for HIV and learn that they are infected can make significant behavior changes to improve their health and reduce the risk of transmitting HIV to their sex or drug-using partners. Recent scientific advances have demonstrated that early initiation of antiretroviral therapy (ART) not only preserves the health of people living with HIV but also reduces their risk of transmitting HIV to others by 93%.3
PrEP is short for pre-exposure prophylaxis. People who do not have HIV can take a daily pill to reduce their risk of becoming infected. PrEP is not right for everyone and must still be used in combination with safer sex and injection practices. It requires commitment to treatment and does not replace other prevention measures like condom use. It also requires very regular medical visits and frequent blood tests for STDs and HIV, because unknowingly continuing PrEP medication while HIV-infected can lead to resistance and limit HIV treatment options. Resistance has already been reported in a person who became infected while taking PrEP.
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.
AIDS is caused by a virus called HIV, the Human Immunodeficiency Virus. If you get infected with HIV, your body will try to fight the infection. It will make “antibodies,” special molecules to fight HIV.
Some people with HIV infection have no symptoms until several months or even years after contracting the virus. However, around 80 percent may develop symptoms similar to flu 2–6 weeks after catching the virus. This is called acute retroviral syndrome.
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 prefer 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).

Human T-cell lymphotropic virus type III; a cytopathic retrovirus that is 100-120 nm in diameter, has a lipid envelope, and has a characteristic dense cylindric nucleoid containing core proteins and genomic RNA; two types exist: HIV-1 infects only humans and chimpanzees and is more virulent than HIV-2, which is more closely related to Simian or monkey viruses. HIV-2 is found primarily in West Africa. It is the etiologic agent of acquired immunodeficiency syndrome (AIDS).
