How do AIDS attack and spread? the 5 ways it attacks the cells is: 1. HIV attaches to the surface. 2. Virus makes a copy of its genetic material. 3. Virus core enters cell and goes to the nucleus. 4. New virus assembles at cell suface. 5. New virus breaks away from the host cell. IT IS SPREADED BY 3 WAYS: 1. Sexual intercourse. 2. Sharing needles. 3. Mother to baby.

HIV (Human Immunodeficiency Virus) attacks the body through the immune system. It substantially weakens the body's ability to fight off common infections. Something as minor a…s the flu can be fatal when someone has an advanced stage of HIV or AIDS. From a more physiopathological angle, the HIV is a retrovirus whose portions of its capside are highly attracted to the CD-4 receptors located on the surface of certain cells. Unfortunately, these cells are T-helper lymphocytes. T-helper lymphocytes are the most important cells of the immunitary system, as they are responsible for both immune responses (humoral immunity [which includes the production of antibodies] and cellular immunity [which basically kills foreing cells]). The HIV virus reproduces by diverting the cellular factory of T-helper lymphocytes, which then kills the latters. Without the chemical action of T-helper lymphocytes, the whole immune system can't work normally anymore.
HIV attacks and destroys the immune system, specifically the white blood cells that fight infection.
How can you get HIV? You can get HIV from your mom or dad. When your mom and dad has sex, one of then has HIV. If your dad has HIV and he did sex with your mom and… than your mom get it. Then your mom has a baby and then your moms baby will get it. When she has the baby the baby will have it when he grow up. Then your mom and dad will die. Then the baby grow up he will not live long he will die when it comes time. How can HIV not be spread? The only thing is to be heath is to not have sex with no one or you could get HIV. You can't get HIV from kiss. DON'T HAVE SEX WITH NO ONE.
Yes Now this means they must have the HIV virus in their body rather than just have to have a positive HIV test (since sometimes they're wrong)
This question is better answered by covering which parts of the body DO cause the spread of HIV infection. HIV (Human Immunodeficiency Virus) is spread by contact with infecte…d body fluids (blood, semen, vaginal fluid or breast milk.) No other parts or fluids of the body carry any risk.
Tattooing may spread HIV if not done correctly. HIV is spread through contact with infected blood, semen, vaginal fluid or breast milk. Tattoo equipment must be properly clean…ed and new needles must be used with each different client. If necessary safety procedures are not followed, HIV infection could be transmitted.
They don't spread HIV.
it will if you make a wound or an opening to the body. The virus is very unstable and dies quite quickly if not protected in some sort of medium. so there may be a chance if… you are sharing a blade that cuts both users simultaneously. HIV can survive in dry blood and mucous ( nasal discharge) upto 48 hours. HIV is also present in sweat and saliva of a person and will cause infection if it gets into blood. Though medical research shows that percentage virus in saliva and sweat is low to cause infection, there are 15 percent of the cases whose cause if unknown. So the answer would be YES.
After sexual infection, HIV usually remains localised in lymph nodes close to the infection site, where it uses a type of immune cell called a CD4 cell to reproduce. After abo…ut two weeks, HIV then bursts out form these enlarged lymph nodes and spread widely to all parts o the body establishing a systemic (throughout the body) infection. This is when flu-like symptoms often occur. The body then controls HIV for most people, often over many years (commonly 2-10 years), but slowly the immune system becomes damaged. The CD4 cells are an important part of your immune system, but the virus gradually reduces them until the body is too weak to fight infections. HIV treatment reverses this damage allowing CD4 cells to increase again. For people able to access treatment, HIV is now a manageable infection rather than a fatal illness.
HIV is transmitted to any person by coming in contact with infected body fluids such as blood, genital secretions, breast milk, spinal fluid, and synovial fluid.
HIV/AIDS is typically spread via contact with infected bodily fluids/secretions (blood, vaginal secretions, semen, etc.). IV drug abuse with shared needles that have been …used with someone infected with the HIV virus is another way to contract the HIV virus (as well as other infections such as Hepatitis C). I'm not sure if it's possible for HIV to spread in the water, I've never heard of someone getting HIV that way, so I sincerely doubt it. The best way to protect yourself is to practice safe sexual practices (i.e., condoms for every sexual act) and to not share needles.
Not a doctor
Yes. Though blood donation and having sex with someone who has it.
Because the level of HIV virus present in saliva is generally insufficient to pass on the virus to a non-infected person.
