HIV means Human Immunodeficiency Virus. The virus that makes the immune system of a person weak by destruction of vital cells in charge of fighting infection and diseases. There is no HIV cure in the world.

Description of AIDS
- AIDS means Acquired Immunodeficiency Syndrome
- AIDS is a full-blown disease caused by HIV virus.
- Once a person’s immune system is very weak, he\she is said to have AIDS.
- The immune system is not able to fight diseases or infection.
- Certain illnesses and symptoms develop as a result of a person contracting AIDS.
- This happens at the last HIV stage since at this moment the infection is highly advanced.
- Failure to control or treat AIDS can cause death (Avert, 2017).
AIDS is a full-blown disease caused by the HIV virus. A person contracts AIDS after immune system becomes very weak. An AIDS victim is not able to fight infection. AIDS can also be described as the last HIV stage since at this moment the infection is highly advanced. If the symptoms of this disease are not controlled or treated, a person ends up dead
- HIV attacks human’s T- helper cells which are some forms of white cells.
- T-helper cells fight infections and diseases.
- HIVreproduces or grows inside the T-helper cells.
- The virus reproduces while inside these cells.
- The reproduction damages the cells which then causes a person’s natural immune system to be weak.
- A person’s health is the main determinant of how the HIV virus grows.
- Other determinants include treatment and how early a person gets diagonalized (May, 2011).
HIV attacks some forms of white cells called T- helper cells. These cells main duty is to fight infections and diseases. HIV to reproduces in the T-helper cells. The virus makes many copies or reproduces while inside these cells. As a result of the reproduction, the immune system gets damaged which causes it to weak a person’s natural immune system. Other determinants of HIV growth is how constant a person takes treatment and how early a person gets diagonalized. If the antiretroviral treatment is taken correctly, then the immune system remains healthy hence preventing illnesses and symptoms that are associated with development of AIDS

HIV Life Cycle.
- There are a number of stages involved in the HIV life cycle.
- First, the virus attaches itself on the T-helper cell before releasing HIV inside the cell.
- Secondly HIV virus gets inside the T-helper cell where it alters its genetic material
- Third, the virus gets into replication stage where HIV proteins are produced facilitating more production of HIV.
- Lastly, more particles of HIV are released from CD4 cells into a person’s bloodstream (Avert, 2017).
HIV life cycle includes four steps. First, the virus attaches itself on the T-helper cell before releasing HIV inside the cell. After HIV virus gets inside the T-helper cell, it alters its genetic material with an aim of getting into the cell nucleus where it overtakes it. After that the virus gets into replication stage where HIV proteins are produced facilitating more production of HIV. The last stage in the HIV life cycle is the assembly, budding and maturation stage. At this stage more particles of HIV are released from CD4 cells into a person’s bloodstream

- Mild symptoms of HIV may include:
- Swollen lymph nodes
- Yeast infection
- Loss of weight and herpes.
- The only share of knowing if a person is infected with HIV or not is through getting tested.
- HIV testing enables people to make healthy decisions of either preventing the infection or iving positively with the virus (HIV Gov., 2017).
As the HIV virus continues to destroy the immune cells in a person’s body, the person may begin developing some chronic or mild symptoms that may include fatigue, fever, diarrhea, swollen lymph nodes, yeast infection, loss of weight and herpes zoster. It is not advisable to rely on the above symptoms alone because they are familiar with symptoms of other illnesses. The only share of knowing if a person is infected with HIV or not is through getting tested. It is important to get tested for HIV because a person is able to make healthy decisions of either preventing the infection or living positively with the virus
- The late HIV infection stage or full- blown AIDS has symptoms that may include:

- ART is a combination of a number of drugs.

- Factors considered in drug prescription include allergy presence, costs and side effects.
HIV treatment involves use of ART. ART is basically a combination of a number of drugs. Currently, there are 25 varying medicines that have been approved by FDA to treat HIV (Kalichan, 2013). The ART drugs function through preventing HI V virus from duplicating. As such, the immune system of the victim is maintained while the HIV progression is slowed down. Before prescribing these drugs to a patient, a doctor considers a number of factors such as allergy presence, costs and side effects
HIV drugs classification
- HIV drugs is classified into six classes that include
- CCR5 antagonists
- Fusion inhibitors
- Intergrase stand transfer inhibitors
- Non-nucleoside reverse transcriptase inhibitors
- Nuleoside reverse transcriptase inibitors
- Protease inhibitors (Health-line, 2017).

- One should avoid unprotected sex and avoiding sharing of needles.
- Avoid anal, oral and vaginal sex.

The only way HIV virus can be prevented is through avoiding risky behaviors. Among risky behaviors that can help prevent AIDS is avoiding unprotected sex and avoiding sharing of needles. HIV can also be prevented through avoidance of anal, oral and vaginal sex. Another prevention measure is to ensure that one only engages in sex with a single partner who is known to be free from HIV infection. A condom can also be used to prevent HIV infection if they are well and consistently used
- Avoid risky sexual behaviors with multiple partners.
- Avoid street drugs that require injections
- Sharing of injections should also be avoided.
- Drugs should be fixed with sterile water
- The skin of a patient should be cleaned with alcohol swab during injection.
- Needles should be disposed in the right manner.
- Avoid contact of body fluids with naked hands
It is also important to avoid risky sexual behaviors with multiple partners. Avoidance of street drugs that require injections is also important in the effort to avoid HIV virus. Sharing of injections is also very risky when it comes to spreading HIV virus. Drugs should be fixed with sterile water with the skin of a patient being cleaned with alcohol swab during injection. Needles should also be disposed in the right manner.
- Use ART to prevent transmission of HIV from a mother to the baby during pregnancy
- Mothers should ensure that they are tested of HIV early in pregnancy
- In case of infection the right precautions are taken to secure the baby from infection.
- Drugs can be taken by people that are not infected to lower their chances of infection (NAP, 2018).
To prevent transmission of HIV from a mother to the baby during pregnancy, ART drugs should be used. Mothers should ensure that they are tested of HIV early in pregnancy to ensure that the right precautions are taken to secure the baby from infection. Most importantly, there are drugs that can be taken by people that are not infected to lower their chances of infection
