What is HIV and five symptoms of hiv?

Answer 1

Aids is a disease caused by the human immunodeficiency virus (HIV), which kills or impairs cells of the immune system and progressively destroys the body. So the difference would be HIV is the disease which causes the symptom AIDS.
HIV is the virus that causes AIDS.

Answer 2

The symptoms of AIDS are primarily the result of infections that do not normally develop in individuals with healthy immune systems. These are called opportunistic infections.

People with AIDS have had their immune system depleted by HIV and are very susceptible to these opportunistic infections. Common symptoms are fevers, sweats (particularly at night), swollen lymph glands, chills, weakness, and weight loss.

See the signs and tests section below for a list of common opportunistic infections and major symptoms associated with them.

Note: Initial infection with HIV may produce no symptoms. Some people, however, do experience flu-like symptoms with fever, rash, sore throat, and swollen lymph nodes, usually 2 weeks after contracting the virus. Some people with HIV infection remain without symptoms for years between the time they are exposed to the virus and when they develop AIDS.

Answer 3

• HIV stands for the human immunodeficiency virus. It is one of a group of viruses known as retroviruses. After getting into the body, the virus kills or damages cells of the body's immune system. The body tries to keep up by making new 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 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.
• AIDS stands for the acquired immunodeficiency syndrome. It is caused by HIV and occurs when the virus has destroyed so much of the body's defenses that immune-cell counts fall to critical levels or certain life-threatening infections or cancers develop

SYMPTOMS

• Many people do not develop symptoms after they first get infected with HIV. Others have a history of a flu-like illness within several days to weeks after exposure to the virus. Early HIV symptoms also include fever, headache, tiredness, and enlarged lymph nodes in the neck. These symptoms usually disappear on their own within a few weeks. After that, the person feels normal and has no symptoms. This asymptomatic phase often lasts for years.
• The progression of disease varies widely among individuals. This state may last from a few months to more than 10 years.
• • During this period, the virus continues to multiply actively and infects and kills the cells of the immune system.
  • The virus destroys the cells that are the primary infection fighters, a type of white blood cell called CD4 cells.
  • Even though the person has no symptoms, he or she is contagious and can pass HIV to others through the routes listed above.

AIDS is the later stage of HIV infection, when the body begins losing its ability to fight infections. Once the CD4 cell count falls low enough, an infected person is said to have AIDS. Sometimes, the diagnosis of AIDS is made because the person has unusual infections or cancers that show how weak the immune system is.

• The infections that happen with AIDS are called opportunistic infections because they take advantage of the opportunity to infect a weakened host. The infections include (but are not limited to)
• • pneumonia caused by Pneumocystis, which causes wheezing;
  • brain infection with toxoplasmosis which can cause trouble thinking or symptoms that mimic a stroke;
  • widespread infection with a bacteria called MAC (mycobacterium avium complex) which can cause fever and weight loss;
  • yeast infection of the swallowing tube (esophagus) which causes pain with swallowing;
  • widespread diseases with certain fungi like histoplasmosis, which can cause fever, cough, anemia, and other problems.
• A weakened immune system can also lead to other unusual conditions:
• • lymphoma in (a form of cancer of the lymphoid tissue) in the brain, which can cause fever and trouble thinking;
  • a cancer of the soft tissues called Kaposi's sarcoma, which causes brown, reddish, or purple spots that develop on the skin or in the mouth

Answer 4

HIV=Human Immunodeficiency Virus. There are no reliable signs or symptoms of HIV infection. The only way a person can know if they are infected is to get tested.

Answer 5

its when a person with the hiv strain passes bodily fluids to another person causing the spread. the symptoms are being gay.
