Overview Acquired immunodeficiency syndrome (AIDS) is the condition that results from long-term (chronic) HIV infection and is defined by an absolute CD4 cell count of less than 200 cells/µL and specific opportunistic infections or malignancies.

- Skin, mouth, genital symptoms — One characteristic feature of acute HIV infection is open sores or ulcers. These sores or ulcers can develop in the mouth, the esophagus (the tube that extends from the mouth to the stomach), the anus, or the penis. The ulcers are usually painful.

- Symptoms of HIV and AIDS. The symptoms of HIV vary widely and depend on both the individual and the stage of the disease. Acute stage symptoms. In the first stage of HIV, 2 to 4 weeks after getting the virus, people can experience flu-like symptoms including: aching muscles; chills; fatigue; fever; mouth ulcers; night sweats; rashes; sore throat; swollen lymph nodes

Comprehensive, up-to-date information on HIV/AIDS treatment and prevention from the University of California San Francisco The infections are called opportunistic because they take the opportunity to attack you when your immune system is weak. The cancers are called AIDS related because they appear mostly in people who have advanced, later-stage HIV infection, known as AIDS. Most people who die of AIDS do not die from the virus itself. They die from opportunistic infections (or OIs). Often, people are infected with the OI long before they become infected with HIV. Their functioning immune system keeps the OI under control, so they don't have any symptoms of the infection.

- Stage 1: Acute HIV infection. Within 2 to 4 weeks after infection with HIV, people may experience a flu-like illness, which may last for a few weeks. This is the body’s natural response to infection. When people have acute HIV infection, they have a large amount of virus in their blood and are very contagious.

AIDS During the late stage of this disease an organism is very prone to opportunistic infections (infections caused by organisms that normally do not cause disease) and tumours (abnormal growth of an organ's tissue). Today, AIDS is still an incurable and fatal disease.t is hard to believe but HIV is actually a very fragile organism. If HIV is outside the body, its capsid disintegrates very quickly which instantly 'disarms' the virus. That is why infection is virtually impossible without direct blood-to-blood contact or through the mixing of body fluids containing the virus.

- 1 PCP is still the most common opportunistic infection in people with HIV/AIDS. Those with a CD4 cell count less than 200 are at highest risk. (CD4 cells are a type of immune system cell. HIV attacks these cells.)  About 9% of patients with HIV/AIDS who are hospitalized have PCP.

- The symptoms of HIV and AIDS vary, depending on the phase of infection. Primary infection (Acute HIV) The majority of people infected by HIV develop a flu-like illness within a month or two after the virus enters the body. This illness, known as primary or acute HIV infection, may last for a few weeks. Possible signs and symptoms include: Fever.

Early Signs of HIV Depending on the phase of HIV, symptoms can vary. The first stage of HIV is known as acute or primary HIV infection. It’s also called acute retroviral syndrome. During this stage, most people experience common flu-like symptoms that may be hard to distinguish from a gastrointestinal or respiratory infection.

Complications of HIV Infection: A Systems-Based Approach Patients with human immunodeficiency virus (HIV) infection often develop multiple complications and comorbidities. Opportunistic infections should always be considered in the evaluation of symptomatic patients with advanced HIV/AIDS, although the overall incidence of these infections has decreased.

HIV The human immunodeficiency virus (HIV) is a lentivirus (a subgroup of retrovirus) that causes HIV infection and acquired immunodeficiency syndrome (AIDS).AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive.Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype.nfection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.

OPPORTUNISTIC INFECTIONS. 2  In general, people with CD4 counts greater than 500 cells/mm 3 are not at risk for opportunistic infections. 3  For people with CD4 counts around 500, however, the daily fluctuations in CD4 cell levels can leave them vulnerable to minor infections, such as candidal vaginitis or yeast infections.

What Are HIV and AIDS? AIDS is the most severe phase of HIV infection. People with AIDS have such badly damaged immune systems that they get an increasing number of severe illnesses, called opportunistic illnesses. Without treatment, people with AIDS typically survive about 3 years. Common symptoms of AIDS include chills, fever, sweats, swollen lymph glands, weakness, and weight loss.

HIV & AIDS guide The Symptoms of HIV/AIDS-the First Stage. HIV infection comes in three stages. The first stage is called acute infection or seroconversion, and it typically happens within two to six weeks after exposure or becoming infected. This is when the body's immune system puts up a fight against HIV.uring this period without symptoms, HIV is slowly killing the CD4 T-cells and destroying the immune system. Blood tests during this time can reveal the number of these CD4 T-cells. Normally, a person has a CD4 T-cell count between 450 and 1,400 cells per microliter.

- Lasting for just a few weeks, this stage of HIV often goes completely unnoticed. This stage, known as the asymptomatic stage is the second of all the stages of HIV. As inferred by the name, this stage is lacks any apparent symptom, and is literally the chronic stage of HIV.

Opportunistic Infections Opportunistic infections (OIs) are infections that occur more frequently and are more severe in individuals with weakened immune systems, including people with HIV.

Opportunistic infection 1 In patients with HIV, starting antiretroviral therapy is especially important for restoration of the immune system and reduces the incidence of all opportunistic infections.  In patients undergoing chemotherapy, completion of and recovery from treatment is the primary method for immune system restoration.

AIDS The definition of AIDS has been refined as more knowledge has become available. In general it refers to that period in the infection when the CD4 count goes below 200 (from a normal count of 1,000) or when the characteristic opportunistic infections and cancers appear.

- Advanced Symptoms of HIV/AIDS. As HIV progresses, there may be bouts of diarrhea, nausea, vomiting, and weight loss. Other symptoms include severe headache, joint pain, and muscle aches. Shortness of breath, chronic cough, and difficulty swallowing are not uncommon. In the later stages, HIV can lead to short-term memory loss, mental confusion, and coma. The most advanced stage of HIV is called acquired immune deficiency syndrome (AIDS). At this stage, the immune system is severely compromised and infections become increasingly difficult to fight off.
