How does HIV attack and spread?
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.

Answer . Regardless of whether you ejaculate inside or outside of your partner, they have still been exposed to your body fluids by way of seminal fluid (AKA: Pre-cum), whi…ch contains HIV. Seminal fluid is the body's natural production of lubrication in preparation of a sexual event. Seminal fluid may not contain as much concentration as in semen, but it is still exposure and potentially infective due to the exposure of bodily fluids between two people.
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.
replicating inside the cells of the immune system.
No, mosquitoes drink and consume the blood. They don't inject it into a new person. No one has ever gotten HIV from a mosquito. The short answer is that you cannot get HIV fro…m a mosquito bite. The mosquito itself cannot be infected with the human immunodeficiency virus. It cannot spread the virus from one human to another. HIV can be ingested by a mosquito, but it can't infect the mosquito and replicate in it, so the mosquito can't spread HIV. Mosquitoes lack the ability to transmit the HIV virus. Mosquito-HIV transmission has become the ultimate QTND (question that never dies!). See below for a small sampling of what's in the archives. Your HIV risk from smashing a blood-filled mosquito on your leg is exactly zero! There is a technical scientific explanation why this is the case, but it's rather tedious. It involves what happens to HIV once it leaves the human host and enters the mosquito. In addition, there would not be enough HIV to cause an infection via this route. Please note we've been monitoring HIV for over 27 years. This question has been studied from every possible angle. Mosquitoes don't transmit HIV. That is not enough blood to give you HIV. There must be a significant amount for you to get infected and a mosquito cannot give you HIV/AIDS. Besides, the blood doesn't go directly into your bloodstream because the blood from the mosquito might be going into your muscle, fatty layer, etc. It just doesn't work with something as small as a mosquito. HIV does not survive long enough to be transmitted from person to person by a mosquito bite. The disease does not work like that. AIDS attacks cells as a retrovirus. So, it basically works backwards. That and the mosquito has enzymes that break down certain viruses and bacteria. Also, usually after one feast, the mosquito is at its fill. The blood would need to be injected into your body, which is not what happens during a mosquito bite.
HIV attacks and destroys the immune system, specifically the white blood cells that fight infection.
\n. \nHow 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)
The answer to this question varies by circumstance and location. In the United States, the states make the specific laws that deal with HIV transmission. Some states have leg…islation in place while others have yet to address the topic. In states where HIV transmission is legislatively regulated, like Indiana, these laws are often called "Duty to Warn" laws. In short, the laws usually require that, when a person is aware they are HIV positive, they are required to warn any furture partners before engaging in at-risk behaviors with them. However, if a person is unaware of their HIV status, they would not be liable for transmitting infection. These laws vary by state. Some states, like Kentucky, do not have regulations in place at this time.
In the first place it took time before anyone realised that it even existed, by this time it had already spread all over the world. secondly it is spread through a thoroughly …pleasant pastime, sex, it was also spread through contaminated blood products. But the thing that probably had more to do with the uncontrolled spread of aids is the outlook that the churches and so called respectable people and the church had towards it. Rather then behave in a responsible and compassionate way they used it to scare people they fought safer sex methods tooth and nail and did whatever they could to misinform and to put fear into the hearts of people.
No. Condoms effectively protect against infection.
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 cannot spread through skin unless there are cuts or open wounds or sores. HIV can spread through mucous membranes which is the soft, often moist tissue in some organs, …for example the tissue that layers the inside of the vagina, the head o f mans penis or the inner foreskin or an uncircumcised man.
Insects such as mosquitoes, flies, ticks, fleas, bees, and wasps cannot spread HIV. If an insect bites a person with HIV, the virus dies as the insect digests the blood. HIV i…s only able to live in human cells.
Not if the woman is not infected with HIV.
HIV can be spread via vaginal, oral, or anal sex. It can be spreadbetween heterosexual couples and homosexual couples. It can also bespread if someone shares an infected needl…e (usually for drugs)with another person.
Yes. Though blood donation and having sex with someone who has it.
