Virus Human Immunodeficiency Virus (HIV) is a microorganism that attacks the immune system of people, causing weakening and making it more vulnerable to a range of infections, endangering life, in some cases.
This virus cannot do anything without living cells; It is like a disembodied brain. So to create more viruses (and all the other nasty things that trigger), the virus has to infect a cell.
It is scientifically proven that this virus mainly attacks the CD4 cells, also known as T cells or helper T cells, which are white blood cells that coordinate the immune system so that the fight against infections and all kinds of diseases.
It is estimated that around 37 million people in the world living with HIV / AIDS. Where more than 40% of these people are concentrated in sub -Saharan Africa and the vast majority are women. HIV can be transmitted through contact with a body fluid (semen, blood, breast milk) from an infected person to a healthy person’s body.
Routes of Transmission of Virus
- sexual contact, unprotected, with an infected person
- Pre-ejaculatory fluid (pre-cum)
- Blood (including menstrual blood)
- Transmission from mother to child.Babies born to infected mothers may become infected with HIV before or during birth; or when they are being breastfed.
- Transmission to receive a donation of blood or blood clotting factors.
Also, several studies show that this virus is not transmitted through saliva, touch by touch, hug and kiss on the cheek, breathing, and masturbation, shaking hands or sharing utensils such as cups, forks or spoons.
The virus HIV must enter the bloodstream, so it is not enough to have just been in contact with an infected fluid for contracting HIV. The skin does not allow HIV to enter the body, this can only enter only through a new cut open or cut brush, or through contact with mucous membranes.
