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:
- Unprotected sexual interaction with an already infected person.
- Reusing needles used by an infected person.
- From an infected mother to the baby through the placenta.
- 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 Property | AIDS | HIV |
Full form | Acquired Immunodeficiency Syndrome (AIDS) is the disease. | Human Immunodeficiency Virus (HIV) is the causal factor (reason) for AIDS. |
Spread | AIDS is a condition acquired only after the contraction of HIV | HIV is a virus and like other viruses, can spread from person to person. |
Kill | Complications and secondary infections from this disease kill the host. | The virus is incapable of killing a host by itself. |
Infection | While 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 for | AIDS stands for acquired immune deficiency syndrome. | HIV stands for human immune deficiency virus. |
Refers | AIDS 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. |
