By the end of 1990, over 307,000 AIDS cases had been officially reported with the actual number estimated to be closer to a million. Between 8-10 million people were thought to be living with HIV worldwide.50

HIV is passed from person to person through bodily fluids such as blood and semen. Once the virus enters your body, it attacks your immune system by destroying CD4 cells, which help keep you from getting sick.
If you have these symptoms, that doesn’t mean you have HIV. Each of these symptoms can be caused by other illnesses. But if you have these symptoms after a potential exposure to HIV, see a health care provider and tell them about your risk. The only way to determine whether you are infected is to be tested for HIV infection.

People with AIDS have had their immune system damaged by HIV. They are at very high risk of getting infections that are uncommon in people with a healthy immune system. These infections are called opportunistic infections. These can be caused by bacteria, viruses, fungi, or protozoa, and can affect any part of the body. People with AIDS are also at higher risk for certain cancers, especially lymphomas and a skin cancer called Kaposi sarcoma.

Seroconversion may take a few weeks, up to several months. Symptoms during this time may include fever, flulike illness, lymphadenopathy, and rash. These manifestations develop in approximately half of all people infected with HIV.

Patients with AIDS have had their immune system depleted by HIV and are very susceptible to such opportunistic infections. Common symptoms are fevers, sweats (particularly at night), swollen glands, chills, weakness, and weight loss.
Historically, the greatest success in preventing viral transmission has resulted from the development of preventative vaccines. Unfortunately, decades of research to develop an HIV vaccine has led to little hope for success. In 2007, a major setback in this area occurred when the STEP study investigating a promising vaccine candidate was prematurely stopped due to the lack of evidence that it produced any protection from HIV infection. In contrast, a glimmer of hope did emerge with the report in 2009 of the results of the RV 144 Thai HIV vaccine trial, which demonstrated borderline effectiveness in the more than 16,000 recipients. While this vaccine demonstrated only limited evidence of protection, research is under way to further explore what can be learned for future vaccine development from this modest success.
Protease inhibitors. Protease inhibitors work by disabling protease, an enzyme necessary for HIV reproduction. Protease inhibitors include saquinavir (Invirase), ritonavir (Norvire), indinavir (Crixivan), nelfinavir (Viracept), amprenavir (Agenerase), kaletra, and many others.
At the same time, it is important to recognise that reaching an undetectable viral load is determined by many factors, including treatment adherence, HIV resistance to certain anti-retroviral drugs, stigma, and inadequate health systems.
The incidence of AIDS by date of diagnosis (assuming an almost constant population at risk) has roughly doubled every half-year since the second half of 1979 (Table 1). An average of one to two cases are now diagnosed every day. Although the overall case-mortality rate for the current total of 593 is 41%, the rate exceeds 60% for cases diagnosed over a year ago.
Studies with powerful drugs that completely block the cycle of HIV replication indicate that the virus is replicating rapidly at all phases of infection, including the asymptomatic phase. Two viral proteins in particular have been the target of drugs aimed at arresting viral replication. These are the viral reverse transcriptase, which is required for synthesis of the provirus, and the viral protease, which cleaves the viral polyproteins to produce the virion proteins and viral enzymes. Inhibitors of these enzymes prevent the establishment of further infection in uninfected cells. Cells that are already infected can continue to produce virions because, once the provirus is established, reverse transcriptase is not needed to make new virus particles, while the viral protease acts at a very late maturation step of the virus, and inhibition of the protease does not prevent virus from being released. However, in both cases, the released virions are not infectious and further cycles of infection and replication are prevented.
Some people may develop a flu-like illness within a month or two after exposure to the HIV virus, although many people do not develop any symptoms at all when they first become infected. Many people mistake this flu-like illness as being caused by something else. Persistent or severe symptoms may not surface for 10 years or more, after HIV first enters the body in adults, or within two years in children born with an HIV infection.

There are medicines that help people with AIDS. These are called antiretroviral medicines (or antiretrovirals.) Anti- means against. HIV is a retrovirus. So antiretroviral means it fights retroviruses.
HIV is one of a group of viruses known as retroviruses. After getting into the body, the virus enters many different cells, incorporates its genes into the human DNA, and hijacks the cell to produce HIV virus. Most importantly, HIV attacks cells of the body’s immune system called CD4 or T-helper cells (T cells). These cells are destroyed by the infection. The body tries to keep up by making new T cells or trying to contain the virus, but eventually the HIV wins out and progressively destroys the body’s ability to fight infections and certain cancers. The virus structure has been studied extensively, and this ongoing research has helped scientists develop new treatments for HIV/AIDS. Although all HIV viruses are similar, small variations or mutations in the genetic material of the virus create drug-resistant viruses. Larger variations in the viral genes are found in different viral subtypes. Currently, HIV-1 is the predominant subtype that causes HIV/AIDS. HIV-2, another form of HIV, occurs almost exclusively in West Africa.
