Preexposure Prophylaxis for the Prevention of HIV Infection in the United States – 2014 Clinical Practice Guideline. Centers for Disease Control and Prevention. May 2014. Available at http://www.cdc.gov/hiv/pdf/PrEPguidelines2014.pdf.
The goals of antiviral therapy are to enhance immunity and delay or prevent clinical advancement to symptomatic disease without inducing important side effects or selecting for drug-resistant virus. Currently, the best marker of a drug’s activity is a decrease in the viral load.
A final prevention strategy of last resort is the use of antiretrovirals as post-exposure prophylaxis, so-called “PEP,” to prevent infection after a potential exposure to HIV-containing blood or genital secretions. Animal studies and some human experience suggest that PEP may be effective in preventing HIV transmission, and it is based upon these limited data that current recommendations have been developed for health care workers and people in the community exposed to potentially infectious material. Current guidelines suggest that those experiencing a needle stick or who are sexually exposed to genital secretions of an HIV-infected person should take antiretrovirals for four weeks. Those individuals considering this type of preventative treatment, however, must be aware that post-exposure treatment cannot be relied upon to prevent HIV infection. Moreover, such treatment is not always available at the time it is most needed and is probably best restricted to unusual and unexpected exposures, such as a broken condom during intercourse. If PEP is to be initiated, it should occur within hours of exposure and certainly within the first several days. Updated guidelines are published and available at https://aidsinfo.nih.gov/.
As the center of the epidemic has moved from New York and San Francisco to the smaller cities in the South, and from gay white men of means to poorer people of color, L.G.B.T. advocacy and fund-raising has shifted to marriage equality. In 2013, H.I.V. activists persuaded 35 L.G.B.T. leaders to sign a statement and create a video imploring the greater gay community to recommit to the AIDS struggle. The message: “We need you to come back.” But of $168 million in H.I.V./AIDS philanthropic dollars spent in the United States in 2015, $31 million was disbursed to the South, just 19 percent of total H.I.V. philanthropy in the United States; only $26 million directly targeted African-Americans, and just $16 million went directly to gay and bisexual men, according to the organization Funders Concerned About AIDS.
Problems surrounding AIDS education are unlikely to go away. Communities frequently disagree on sex education itself, and compromise is often difficult on such a divisive issue of values. As the experience of the Clinton administration suggested, Washington, D.C., could easily exacerbate an already contentious area, with policy coordinators becoming lightning rods for criticism. On the matter of what to say to kids about AIDS, poll data have been misleading. U.S. citizens are of three minds: say a lot, say a little, and do not say what the other side thinks.
Diagnostic blood tests for AIDS are given to individuals in high-risk populations, pregnant women, health care and public service workers who have been exposed to HIV, those who have symptoms associated with AIDS, or others who fear they may have been exposed to the virus. The first blood test for AIDS was developed in 1985. Patients who are being tested for HIV infection are usually given an enzyme-linked immunosorbent assay (ELISA) test for the presence of HIV antibody in their blood. Positive ELISA results are then tested with a Western blot or immunofluorescence (IFA) assay for confirmation. The combination of the ELISA and Western blot tests is more than 99.9% accurate in detecting HIV infection within four to eight weeks following exposure. The polymerase chain reaction (PCR) test can be used to detect the presence of viral nucleic acids in the very small number of HIV patients who have false-negative results on the ELISA and Western blot tests. These tests are also used to detect viruses and bacteria other than HIV and AIDS.
“Terminal Velocity,” a 1994 film in which he played a skydiving instructor, fared even worse. Critics wondered whether the film was a goof, comparable to Sheen’s “Hot Shots!” parody series. It made just $17 million at the box office on a $50 million budget.

HIV is the virus that’s passed from person to person. Over time, HIV destroys an important kind of the cell in your immune system (called CD4 cells or T cells) that helps protect you from infections. When you don’t have enough of these CD4 cells, your body can’t fight off infections the way it normally can.
June Gipson, president and chief executive of My Brother’s Keeper, the Jackson nonprofit Cedric Sturdevant works for, believes that the repeal of the Affordable Care Act wouldn’t have an immediate catastrophic effect in her state — but only because things are already so dire. Like most of the South, Mississippi refused Medicaid expansion, and nearly half of its citizens who are living with H.I.V. rely on the Ryan White H.I.V./AIDS Program to stay alive. Named for an Indiana teenager who contracted H.I.V. through a blood transfusion in the ’80s, this federal program provides funding for H.I.V. treatment and care for those who have no other way to finance their medication. If the A.C.A. is repealed, Gipson said, “it just means that the entire country becomes Mississippi.”
Sturdevant, born and raised in Metcalfe, a tiny Mississippi Delta town of about 1,000, understands all too well the fear, stigma and isolation that can come with being a black gay man in the South. “Growing up, I was taught that God was not fixing to forgive a person who was homosexual,” Sturdevant said. “The Bible supposedly said you’re going straight to hell, automatically, there’s no forgiveness. There were several times I thought about suicide. There were several times I wanted to get sick and die. Finally, my thought was, I just want to get out of here.” He moved to Dallas, and then to Memphis.

Not everyone who has HIV have AIDS. When people first get HIV, they can be healthy for years. A person is diagnosed as having AIDS when he or she gets specific types of illnesses or gets sick in certain ways due to their HIV. Once a person’s HIV progresses to (or turns into) AIDS, the person will continue to have AIDS for the rest of their life. While there are many treatments for HIV/AIDS, at this point there is no cure.

After this earliest stage of HIV infection, HIV continues to multiply but at very low levels. More severe symptoms of HIV infection, such as signs of opportunistic infections, generally don’t appear for many years. (Opportunistic infections are infections and infection-related cancers that occur more frequently or are more severe in people with weakened immune systems than in people with healthy immune systems.)
“Charlie does not have AIDS,” Huizenga said. “AIDS is a condition where the HIV virus markedly suppresses the immune system and you are susceptible to rare, difficult cancers and infections. Charlie has none of those. He is healthy; he does not have AIDS.”
This past July, results came in on the third case. In 2010, a girl known as the Mississippi baby was born to an H.I.V.-positive mother who had taken no antiretrovirals, and the baby had the virus in her blood. Thirty hours after delivery, the newborn started on antiretroviral therapy. Within weeks, the viral count fell below the limit of detection. The baby was eighteen months old when the treatment was interrupted, against medical advice. For two years, the girl’s blood showed no trace of the virus, and researchers speculated that very early HAART might prevent the virus from forming a dormant reservoir. Twenty-seven months after going off the drugs, however, the child tested positive for the virus. Though researchers were impressed that early intervention had temporarily banished H.I.V., she was not cured.

Side effects vary and may include headache and dizziness. Serious side effects include swelling of the mouth and tongue and liver damage. Some people eventually develop drug-resistant strains of HIV. If you have serious side effects, your medications can be adjusted.
In August, Janet and Robert Siliciano wrote about the Brigham men and the Mississippi baby in Science, saying that the cases confirmed that researchers were on the right path in attacking latent infection. The Berlin patient was an even more compelling example. Karl Salzwedel, the chief of Pathogenesis and Basic Research in the Division of aids at the National Institute of Allergy and Infectious Diseases, told me that until Timothy Brown “it wasn’t really clear how we would go about getting rid of the last bits of virus that remain in the reservoir.” Brown’s case provided “a proof of concept: it may be possible to eradicate latent H.I.V. from the body. It may be from a very risky and toxic method, but it’s proof of concept nonetheless.”

While sporadic cases of AIDS were documented prior to 1970, available data suggests that the current epidemic started in the mid- to late 1970s. By 1980, HIV may have already spread to five continents (North America, South America, Europe, Africa and Australia). In this period, between 100,000 and 300,000 people could have already been infected.1
Push Congress and the White House to mount the strongest possible response to the epidemic in the form of fully funded public health programs, as well as common sense policy solutions such as comprehensive sex education and syringe/needle exchange.
Sexual contact. People at greatest risk are those who do not practice safer sex by always using a condom, those who have multiple sexual partners, those who participate in anal intercourse, and those who have sex with a partner who has HIV infection and/or other sexually transmitted diseases (STDs). In the United States and Europe, most cases of sexually transmitted HIV infection result from homosexual contact, whereas in Africa, the disease is spread primarily through sexual intercourse among heterosexuals. Most people with AIDS in the United States are between 25 and 44 years of age.
