The main treatment for HIV is antiretroviral therapy (ART), a combination of daily medications that stop the virus from reproducing. This helps protect your CD4 cells, keeping your immune system strong enough to fight off disease.

‘second-class travel’ syndrome pulmonary thromboembolism due to prolonged periods of inactivity, e.g. passengers (who have been static for > 4 hours during long-haul intercontinental air flights) develop deep-vein thrombosis; the clot detaches, passing through venous circulation and heart, to block the pulmonary artery; characterized by sudden collapse and death; passengers on long-haul flights are advised to undertake leg muscle exercises regularly throughout the duration of the flight, wear ‘antithrombotic’ elasticated hosiery and consider medication with aspirin in the weeks before long-haul flight

A transmissible retrovirus that causes AIDS in humans. Two forms of HIV are now recognized: HIV-1, which causes most cases of AIDS in Europe, North and South America, and most parts of Africa; and HIV-2, which is chiefly found in West African patients. HIV-2, discovered in 1986, appears to be less virulent than HIV-1 and may also have a longer latency period.

I tended to our Kaposi-sarcoma patients. I was the most junior person on staff and had no expertise in the tumor, but none of the senior faculty wanted the job. My first patient, a middle-aged fireman nicknamed Bud, lived a closeted life in West Los Angeles. Not long before he checked in to the hospital, he had started to find growths on his legs that looked like ripe cherries. Then they appeared on his torso, on his face, and in his mouth. Despite strong doses of chemotherapy, the standard treatment for advanced Kaposi sarcoma, his tumors grew, disfiguring him and killing him in less than a year. By 1982, men with highly aggressive kinds of lymphoma had started to arrive at the hospital. They, too, failed to improve with chemotherapy. Patients were dying from an array of diseases that had overcome ravaged immune systems. All my patients had one disorder in common, which the C.D.C., that year, had named acquired-immunodeficiency syndrome, or AIDS. Scientists did not yet know what caused it.

Antiretroviral therapy (ART) is the use of HIV medicines to treat HIV infection. People on ART take a combination of HIV medicines (called an HIV regimen) every day. (HIV medicines are often called antiretrovirals or ARVs.)

HIV is a virus spread through certain body fluids that attacks the body’s immune system, specifically the CD4 cells, often called T cells. Over time, HIV can destroy so many of these cells that the body can’t fight off infections and disease. These special cells help the immune system fight off infections. Untreated, HIV reduces the number of CD4 cells (T cells) in the body. This damage to the immune system makes it harder and harder for the body to fight off infections and some other diseases. Opportunistic infections or cancers take advantage of a very weak immune system and signal that the person has AIDS. Learn more about the of HIV and how to know whether you’re infected.

Unlike cellular organisms, viruses do not contain all the biochemical mechanisms for their own replication; they replicate by using the biochemical mechanisms of a host cell to synthesize and assemble their separate components. (Some do contain or produce essential enzymes when there is no cellular enzyme that will serve.) When a complete virus particle (virion) comes in contact with a host cell, only the viral nucleic acid and, in some viruses, a few enzymes are injected into the host cell.

State Legislation and the Courts To stem transmission of HIV, states have adopted several legal measures. Two states attempted to head off the virus at the pass: Illinois and Louisiana at one point required HIV blood testing as a prerequisite to getting a marriage license. Both states ultimately repealed these statutes because they were difficult to enforce; couples simply crossed state lines to be married in neighboring states. Several states have taken a less stringent approach, requiring only that applicants for a marriage license must be informed of the availability—and advisability—of HIV tests. More commonly, states criminalize sexual behavior that can spread AIDS. Michigan law makes it a felony for an HIV or AIDS-infected person to engage in sex without first informing a partner of the infection. Florida law provides for the prosecution of any HIV-positive person committing prostitution, and it permits rape victims to demand that their attackers undergo testing. Indiana imposes penalties on persons who recklessly or knowingly donate blood or semen with the knowledge that they are HIV-infected.

Most (95%) new infections occur in the developing world. Almost 70% of new HIV infections occur in sub-Saharan Africa, with more than half occurring in women and 1 in 10 occurring in children under 15 years old. However, in many sub-Saharan African countries, the number of new HIV infections decreased by 41% between 2000 and 2014., partly because of international efforts to provide treatment and strategies for prevention.

The size of the proviral reservoir correlates to the steady-state viral load and is inversely correlated to the anti-HIV CD8+ T-cell responses. Aggressive early treatment of acute infection may lower the proviral load, but generally, treatment in newly infected (but postseroconversion) patients yields no long-term benefit.

Cultural factors (e.g., stigma, fear, discrimination, and homophobia) might contribute to longer diagnosis delays in some populations (12). Asians accounted for the highest percentage of persons living with undiagnosed HIV infection compared with all other race/ethnicity groups (13). Although blacks were more likely than whites to report testing in the past 12 months across all groups at risk, the median diagnosis delay was 1 year longer for blacks (median = 3.3 years) than for whites (median = 2.2 years). The testing results might reflect national efforts to improve access to testing among blacks, and black MSM in particular, through prevention programs and media campaigns. In 2007, CDC launched the Expanded Testing Initiative (https://www.cdc.gov/hiv/policies/eti.html) to facilitate HIV diagnosis and linkage to care among blacks and continues to support high levels of testing. CDC’s MSM Testing Initiative (https://www.researchgate.net/publication/287201580) scaled up HIV testing and linkage-to-care activities among black and Hispanic or Latino MSM in 11 cities. In addition, CDC implemented Testing Makes Us Stronger (https://www.cdc.gov/actagainstaids/campaigns/tmus), a public education campaign to increase testing among black MSM, from 2011 to 2015.
