As the immune system weakens, symptoms of acute HIV syndrome may appear. About 6 to 8 weeks after acquiring HIV infection, the body starts to defend itself by creating antibodies. The development of antibodies causes the amount of HIV virus to drop but the virus remains in your blood, and never completely goes away. As the amount of virus decreases the immune system gets stronger. The CD4 count can go back up to a near normal if not a normal level.
The period known as acute HIV infection can be referred to by different names such as primary HIV infection, acute retroviral syndrome and acute HIV syndrome. All these names describe this brief stage immediately following HIV infection.
To find out more, see below:
- Fever (usually 101°F or higher)
- Swollen lymph nodes
- Sore throat
- Weight loss
- Muscle aches
- Night sweats
Fever is the most common symptom. Because these symptoms are common in other viral illnesses, the diagnosis of acute HIV is often not suspected and the patient is sent home unaware that they have been recently infected with HIV. Having these symptoms does not mean that you have HIV. The same symptoms can occur with the flu, mononucleosis (mono), strep throat and other viral illnesses. However if you think you may have been exposed to HIV/AIDS and are experiencing some of these symptoms – GET TESTED.
If you don’t know your HIV status, get tested! There are many places around the Triangle region that offer free HIV testing.

The following is a glossary of frequent terms relating to HIV/AIDS and HIV/AIDS clinical trials. A complete glossary can be found at AIDSinfo.com.
|Acquired Immunodeficiency Syndrome (AIDS)||A disease of the immune system due to infection with HIV. HIV destroys the CD4 T lymphocytes (CD4 cells) of the immune system, leaving the body vulnerable to life-threatening infections and cancers. Acquired immunodeficiency syndrome (AIDS) is the most advanced stage of HIV infection. To be diagnosed with AIDS, a person with HIV must have an AIDS-defining condition or have a CD4 count less than 200 cells/mm3 (regardless of whether the person has an AIDS-defining condition).|
|Acute HIV Infection||Early stage of HIV infection that extends approximately 2 to 4 weeks from initial infection until the body produces enough HIV antibodies to be detected by an HIV antibody test. During acute HIV infection, HIV is highly infectious because the virus is multiplying rapidly. The rapid increase in HIV viral load can be detected before HIV antibodies are present.|
|Antibody||A protein produced by B lymphocytes (B cells) in response to an antigen. Antibodies bind to and help destroy antigens.|
|Antibody/Antigen Combination Test||A type of HIV test that can detect HIV-1 and HIV-2 antibodies and HIV-1 p24 antigen (a protein that forms the HIV core). Antigen/antibody combination tests can detect HIV earlier than tests that only detect HIV antibodies. The test is done using a sample of blood.|
|Antigen||Any substance that triggers an immune response. Antigens include bacteria, viruses, and allergens, such as pollen.|
|Antiretroviral (ARV)||A drug used to prevent a retrovirus, such as HIV, from replicating. The term primarily refers to antiretroviral (ARV) HIV drugs.|
|Antiretroviral Therapy (ART)||The daily use of a combination of HIV medicines (called an HIV regimen) to treat HIV infection. A person’s initial HIV regimen generally includes three antiretroviral (ARV) drugs from at least two different HIV drug classes.|
|Biopsy||Removal of tissue, cells, or fluid from the body for examination under a microscope. Biopsies are used to diagnose disease.|
|Broadly Neutralizing Antibodies (bNAbs)||A type of antibody that can recognize and block many types of HIV from entering healthy cells. Broadly neutralizing antibodies (bNAbs) may also activate other immune cells to help destroy HIV-infected cells. Researchers are investigating whether bNAbs could be used to develop a therapeutic HIV vaccine.|
|CD4 cells||A type of lymphocyte. CD4 T lymphocytes (CD4 cells) help coordinate the immune response by stimulating other immune cells, such as macrophages, B lymphocytes (B cells), and CD8 T lymphocytes (CD8 cells), to fight infection. HIV weakens the immune system by destroying CD4 cells.|
|CD4 cell count||A laboratory test that measures the number of CD4 T lymphocytes (CD4 cells) in a sample of blood. In people with HIV, the CD4 count is the most important laboratory indicator of immune function and the strongest predictor of HIV progression. The CD4 count is also used to monitor a person’s response to antiretroviral therapy (ART).|
|Chronic HIV Infection||The stage of HIV infection between acute HIV infection and the onset of AIDS. During chronic HIV infection, HIV levels gradually increase and the number of CD4 cells decrease. Declining CD4 cell levels indicate increasing damage to the immune system. Antiretroviral therapy (ART) can prevent HIV from destroying the immune system and advancing to AIDS.|
|Clinical Trial||A research study that determines whether a new drug (or other intervention) is both safe and effective for humans. People volunteer to participate in clinical trials (also called interventional studies) to help find better ways to treat, prevent, diagnose, and understand human disease. Clinical trials are conducted in “phases.” Results from Phase 1, 2, and 3 trials are used to determine whether a new drug should be approved for sale in the United States. Once a new drug is approved, researchers continue to track its safety in Phase 4 trials.|
|Colonoscopy||An outpatient procedure in which the rectum and the inside of the intestine are examined. During a colonoscopy, a physician uses a colonoscope (a long, flexible instrument about 1/2 inch in diameter) to view the lining of the colon. The colonoscope is inserted through the rectum and advanced to the large intestine. A small amount of tissue will be removed for analysis, this is called a biopsy.|
|DART (Dual Affinity Re-Targeting molecule)||Dual antibodies that engage cytotoxic T-cells with HIV infected cells.|
|Drug Resistance||The ability of some micro-organisms, such as bacteria, viruses, and parasites, to adapt so that they can multiply even in the presence of drugs that would normally kill them.|
|Efficacy||Effectiveness of a drug or other medical intervention under ideal conditions, such as during a clinical trial. Drugs are tested for efficacy to ensure they produce the desired effect on the disease or condition being treated.|
|Electroporation device||A device that delivers an IM vaccine with a small electric shock to increase the permeability
of the cell membrane which allows the vaccine materials to be introduced into the patient’s cells.
|Eligibility Criteria||Factors used to determine whether a person is eligible (inclusion criteria) or not eligible (exclusion criteria) to participate in a clinical trial. Eligibility criteria may include disease type and stage, other medical conditions, previous treatment history, age, and gender.|
|Elite Controllers||A small subset of people living with HIV who are able to maintain suppressed viral loads for years without antiretroviral therapy (ART). However, because HIV continues to replicate even in elite controllers, ART is recommended for elite controllers who have declining CD4 counts or who develop HIV-related complications.|
|Hepatitis B Virus Infection (HBV)||Infection with the hepatitis B virus (HBV). HBV can be transmitted through blood, semen, or other body fluids during sex or injection drug use. HBV infection progresses more rapidly in people with HBV/HIV coinfection than in people who have HBV infection alone.|
|Hepatitis C Virus Infection (HCV)||Infection with the hepatitis C virus (HCV). HCV is usually transmitted through blood and rarely through other body fluids, such as semen. HCV infection progresses more rapidly in people with HCV/HIV coinfection than in people who have HCV infection alone.|
|HIV-1||One of the two types of HIV, the virus that causes AIDS. AIDS is the most advanced stage of HIV infection. HIV-1 is transmitted through direct contact with HIV-infected body fluids, such as blood, semen, and vaginal fluids, or from a mother who has HIV-1 to her child during pregnancy, delivery, or breastfeeding (through breast milk). HIV-1 is responsible for the majority of HIV infections worldwide. In the United States, unless otherwise noted, the term “HIV” primarily refers to HIV-1.|
|HXTC (HIV-1 Expanded Specific T-Cell Therapy)||A patient’s own T-cells are enhanced ex-vivo to better recognize the HIV virus and are re-infused back into to patient.|
|Immune Modulators||Immune modulators are a class of drugs that help to activate, boost, or restore normal immune function after HIV has damaged the immune system. Researchers are investigating whether immune modulators can help change how the immune system functions as part of a strategy to treat or cure HIV. Currently, the immune modulators used to treat HIV infection are still under investigation and have not been approved by the Food and Drug Administration (FDA) for patient use.|
|Informed Consent||A communication process between a person and a health care provider or researcher to ensure that the person understands all relevant facts associated with a medical procedure or clinical trial. Before undergoing the procedure or participating in the trial, the person must sign an informed consent form that indicates understanding of the risks and benefits involved and of the risks and benefits of other options.|
|Institutional Review Board (IRB)||A committee of experts who review and monitor clinical trials to ensure that they are ethical and that the rights of study participants are protected. Federal regulations dictate that any institution that conducts or supports clinical trials must have an IRB.|
|Investigational Drug||A drug that is approved by the Food and Drug Administration (FDA) for testing in humans for a specified condition but not approved for commercial marketing and sale.|
|Kick and Kill Strategy||An experimental strategy to cure HIV infection that is currently under investigation. Finding a cure for HIV is challenging because the virus can remain hidden and inactive (latent) inside certain cells of the immune system (such as CD4 cells) for months or even years. While HIV is in this latent state, the immune system cannot recognize the virus, and antiretroviral therapy (ART) has no effect on it. The shock and kill strategy is a two-step process. First, drugs called latency-reversing agents are used to reactivate latent HIV hiding in immune cells (the “shock”). The reactivated cells can then be targeted and killed by the body’s immune system or anti-HIV drugs.|
|Latency-Reversing Agents||One of the main obstacles to curing HIV infection is that the virus can remain hidden and inactive (latent) inside certain cells of the immune system (such as CD4 cells) for months or even years. While HIV is in this latent state, the immune system cannot recognize the virus, and antiretroviral therapy (ART) has no effect on it. Latency-reversing agents reactivate latent HIV within CD4 cells, allowing ART and the body’s immune system to attack the virus. Currently, latency-reversing agents are still under investigation and have not been approved by the Food and Drug Administration (FDA).|
|Latent HIV Reservoir||Resting CD4 cells (or other cells) that are infected with HIV but not actively producing HIV. Latent HIV reservoirs are established during the earliest stage of HIV infection. Although antiretroviral therapy (ART) can reduce the level of HIV in the blood to an undetectable level, latent reservoirs of HIV continue to survive. When a latently infected cell is reactivated, the cell begins to produce HIV again. Although ART can suppress HIV levels, ART cannot eliminate latent HIV reservoirs. For this reason, ART cannot cure HIV infection.|
|Leukapheresis||The removal of white blood cells (leukocytes) from the peripheral blood. The process requires access to veins in both arms. Blood is extracted from one arm into a machine that sorts out the various blood components according to their density and weight. White cells are removed, and the rest of the blood is returned via a needle in the other arm. The procedure usually takes 3-4 hours.|
|Lumbar Puncture||A procedure in which a needle is inserted into the lower region of the spinal cord to collect cerebrospinal fluid (CSF). The CSF is examined in a laboratory to diagnose and monitor certain infections. A spinal tap may also be performed to inject drugs or to reduce spinal fluid pressure.|
|Nadir||The lowest point. For example, a person’s nadir CD4 count is the person’s lowest CD4 count.|
|Opportunistic Infections (OIs)||An infection that occurs more frequently or is more severe in people with weakened immune systems, such as people with HIV or people receiving chemotherapy, than in people with healthy immune systems.|
|Placebo||An inactive drug (or other intervention) that is identical in appearance to a therapeutically active drug. In some clinical trials, researchers compare the effects of a placebo with those of an active drug under investigation to determine if the active investigational drug is effective.|
|Pre-Exposure Prophylaxis (PrEP)||An HIV prevention method for people who are HIV negative and at high risk of HIV infection. Pre-exposure prophylaxis (PrEP) involves taking a specific combination of HIV medicines daily. PrEP is even more effective when it is combined with condoms and other prevention tools.|
|Protocol||The detailed plan for conducting an experiment such as a clinical trial. A clinical trial protocol is a lengthy document describing the trial’s rationale, purpose, information about the drug or vaccine under study, participant inclusion/exclusion criteria, study endpoints, and details of the trial design.|
|Rapid Test||A type of HIV antibody test used to screen for HIV infection. A rapid HIV antibody test can detect HIV antibodies in blood or oral fluid in less than 30 minutes. There is also a rapid antigen/antibody test available. A positive rapid HIV antibody test must be confirmed by a second test for a person to be definitively diagnosed with HIV infection.|
|Randomization||When participants of a clinical trial are assigned by chance to one of two or more treatment or placebo groups. A randomized trial design helps researchers gather meaningful information and make valid statistical calculations.|
|Toxicity||The extent to which a drug causes adverse effects. Drug toxicity is one of the factors considered when selecting antiretroviral (ARV) drugs to include in an HIV treatment regimen.|
|Treatment-Experienced||When a person with HIV is currently taking or has previously taken antiretroviral (ARV) drugs.|
|Treatment-Naive||When a person with HIV has never taken antiretroviral (ARV) drugs.|
||A combination of 3 broadly neutralizing antibodies against HIV in one molecule.|
|Undetectable Viral Load||When the amount of HIV in the blood is too low to be detected with a viral load (HIV RNA) test. A person’s viral load is considered “durably undetectable” when it remains undetectable for at least 6 months after a first undetectable test result. Antiretroviral (ARV) drugs may reduce a person’s viral load to an undetectable level; however, that does not mean the person is cured. Some HIV, in the form of latent HIV reservoirs, remains inside cells and in body tissues.|
|Vaccine||A substance administered to trigger an immune response against a particular disease. Most vaccines are designed to prevent a person from ever having a particular disease or to only have a mild case of the disease. However, therapeutic vaccines are intended to treat specific diseases.|
|Viral Load (VL)||The amount of HIV in a sample of blood. Viral load (VL) is reported as the number of HIV RNA copies per milliliter of blood. An important goal of antiretroviral therapy (ART) is to suppress a person’s VL to an undetectable level—a level too low for the virus to be detected by a VL test.|
|Virologic Failure||A type of HIV treatment failure. Virologic failure occurs when antiretroviral therapy (ART) fails to suppress and sustain a person’s viral load to less than 200 copies/mL. Factors that can contribute to virologic failure include drug resistance, drug toxicity, and poor adherence to ART.|
|VOR (Vorinostat)||An FDA approved medication for cancer that is being used experimentally as an HIV reservoir latency reversing agent.|
|VRC07-523LS||A Potent broadly neutralizing antibody against HIV with a long half-life.|
