HIV (Human Immunodeficiency Virus) is the virus that causes AIDS (Acquired Immune Deficiency Syndrome). HIV is a retrovirus that needs human cells to replicate itself.
HIV is covered in receptors that allow it to attach to human white blood cells. After attaching to the cell, the virus "reprograms" the way the white blood cell (or "T Cell") to become what could effectively be called a virus factory.
It teaches the cell how to replicate itself.
The process by which HIV reproduces is fairly complex and involves several steps. However, put simply, this is what happens:
- The virus enters the blood stream and directs itself to specific white blood cells called CD4 T helper cells (or T-cells)
- It attaches itself to the CD4 cells and works its way inside the cell
- Using the CD4's biological structure, the virus releases its genetic material (RNA) converts it into DNA and forces the cell to make a copy of the HIV virus.
- Once this process is completed, a new HIV virus breaks free of the original host cell and in most cases, destroys the original CD4 cell.
- The new HIV virus now moves on to another CD4 cells and begins the replication process all over again.
A person contracts HIV from another HIV infected person through unprotected vaginal, anal and possibly oral sex, or through the sharing of needles.
Once HIV is introduced into the body, it enters certain cells and reproduces in them. This produces many copies of the virus and kills the cell. This eventually leads to a working infection which cannot be eliminated.
So practice safe sex!
If you're talking about time, each person is different, but it can begin reproducing immediately.
Keep in mind, HIV and AIDS are 2 different things. HIV turns into AIDS without treatment. You can live with HIV, but by the time it turns into AIDS, it's too late.
HIV reproduces by getting attached to a CD4/T-Cell
its like bacteria, it multiples it self, therefore proliferating until hundreds are made resulting in the infects becoming aids.
They can reproduce but in doing so there is a danger of passing the HIV virus on to the partner they are reproducing with and also passing the infection on to the children they make. Obviously it is a couples choice but many feel that the do not want to expose their partners/offspring to this risk.
Because HIV needs human immune cells to reproduce and does not survive in an insect.
The HIV is a virus and does not perform the bacterial reproduction of binary fission or conjugation in order to reproduce. The only way a virus reproduces is by infecting a host cell.
Viruses need any kind of cell. Some have "favorites" like white blood cells (HIV).
HIV is a retrovirus as it transcribed mRNA into DNA. It invades a host cell and uses the cells machinery to copy its own genetic material. This produces multiple copies of the virus within the host cell, which then ruptures releasing the virus and the process is repeated.
It is not. HIV is a virus. It has a completely different make-up from a bacteria. The most important difference between a bacteria and a virus is that a virus does not have the ability to replicate on its own. It needs a host, another cell, to reproduce, unlike bacteria which can reproduce on their own.
No; it is not possible unless there are large amounts of blood that comes out of the persons mouth when they sneeze.
T helper cells, also called CD4+ T cells (or just CD4 cells) are part of the immune system, but they are also the main target cells that HIV infects and uses to reproduce.
It is better to be HIV negative than HIV positive. An HIV positive person is infected with HIV.
HIV-positive means you are infected with the human immunodeficiency virus. HIV-negative means that you are not infected with the HIV.
No
anyone can get hiv
