AIDS and HIV Differences in Biology Import Concepts Must to Know

Question. Difference Between AIDS and HIV.

Answer:

HIV (Human Immunodeficiency Virus) :

HIV originated in non-human primates and eventually spread to humans over the axons. Even though the disease had been around for a long time, it was clinically diagnosed in the . Ever since then, it has spread all over the world, killing over million people till date.

The HIV infection spreads through the following ways:

  1. Unprotected sexual interaction with an already infected person.
  2. Reusing needles used by an infected person.
  3. From an infected mother to the baby through the placenta.
  4. Blood transfusion from an infected person.

This virus has a long incubation period before it starts to attack the immune system ( years) . The immune system is the human body՚s natural defence mechanism; hence HIV can make it harder for the patient to fight off infections and diseases.

HIV demolishes a particular type of WBC (White Blood Cells) and the T-helper cells. This virus also makes copies of itself inside these cells. T-helper cells are also known as cells.

AIDS (acquired immunodeficiency syndrome) :

  • AIDS or Acquired Immune Deficiency Syndrome is a disease caused by the HIV virus. In this condition, a person՚s immune system becomes too weak to fight any kind of infection or disease. AIDS is usually the last stage of HIV infection; a stage where the body can no longer defend itself and thus spawn various diseases. AIDS, when untreated, leads to death.
  • AIDS is an advanced HIV infection or late-stage HIV. Someone with AIDS may develop a wide range of health conditions like – pneumonia, thrush, fungal infections, TB, toxoplasmosis.

Symptoms of AIDS

  • As AIDS is a virus infection, the symptoms related to acute HIV infection can be similar to flu or other viral illnesses, like: Fever, Muscle & Joint Pain, Chilis, Headaches, Sore throat, Night Sweats, Red rashes, Mouth sores, Tiredness, Swollen lymph glands, Weakness, Weight Loss, Diarrhoea.

Differentiating PropertyAIDSHIV
Full formAcquired Immunodeficiency Syndrome (AIDS) is the disease.Human Immunodeficiency Virus (HIV) is the causal factor (reason) for AIDS.
SpreadAIDS is a condition acquired only after the contraction of HIVHIV is a virus and like other viruses, can spread from person to person.
KillComplications and secondary infections from this disease kill the host.The virus is incapable of killing a host by itself.
InfectionWhile a person can have an HIV infection without having AIDS, anyone diagnosed with AIDS. Already has HIV.HIV infection doesn՚t always progress to AIDS. Many people with HIV live for years without developing AIDS.
Stands forAIDS stands for acquired immune deficiency syndrome.HIV stands for human immune deficiency virus.
RefersAIDS refers to a spectrum of conditions, usually seen during the later stage of infection by the virus – HIV.HIV refers to the virus that invades and weakens the immune system.
