Among dangerous diseases HIV infection is one of the first. The most usual way to be infected is while sex contact. Read the article to find preventive ways.
The human immunodeficiency virus (HIV) is a lentivirus that causes HIV infection and over time acquired immunodeficiency syndrome (AIDS). AIDS is a condition in humans in which progressive failure of the immune system allows life-threatening opportunistic infections and cancers to thrive. Without treatment, average survival time after infection with HIV is estimated to be 9 to 11 years, depending on the HIV subtype. Infection with HIV occurs by the transfer of blood, semen, vaginal fluid, pre-ejaculate, or breast milk. Within these bodily fluids, HIV is present as both free virus particles and virus within infected immune cells.
HIV infects vital cells in the human immune system such as helper T cells (specifically CD4+ T cells), macrophages, and dendritic cells. HIV infection leads to low levels of CD4+ T cells through some mechanisms, including pyroptosis of abortively infected T cells, apoptosis of uninfected bystander cells, direct viral killing of infected cells, and killing of infected CD4+ T cells by CD8 cytotoxic lymphocytes that recognize infected cells. When CD4+ T cell numbers decline below a critical level, cell-mediated immunity is lost, and the body becomes progressively more susceptible to opportunistic infections.
Three decades later after the world became known to the human immunodeficiency virus (HIV) that causes AIDS, the disease has spread widely around the world. Now few people are surprised that among patients may be a family member, childhood friend or colleague
HIV infection probability
It is possible while unprotected (without a condom) penetrative sexual intercourse.
It is possible while sharing needles, syringes, and other injecting equipment.
It is possible while the use of contaminated equipment for tattoos and piercing.
It is possible while using other people's shaving supplies, toothbrushes with visible remnants of blood.
It is possible during transmission of the virus from HIV-positive mother to child during pregnancy, childbirth, and breastfeeding.
Thus, HIV is transmitted through blood, semen, vaginal fluids and breast milk, but not through other body fluids (such as saliva, sweat, tears, urine, and feces).
Using alcohol and drugs, you also run the risk
It must be remembered that alcohol is a drug too, under its influence, the person often loses control over a situation that may cause you to make hasty and risky actions.
How is HIV not transmitted? HIV and AIDS cause fear and anxiety, which often appear exaggerated. People are afraid of contracting HIV through normal household contact. In fact, these concerns are unfounded, and regular contact with people living with HIV/AIDS, it is safe. All modes of HIV transmission are well-researched and scientifically proven.
HIV is not transmitted:
when shaking hands or the arms;
through sweat or tears;
when coughing and sneezing;
when using common utensils or linens;
when you use the shared bath and toilet;
during group activities;
if you stay in the same room;
in public transport;
through animals or insect bites;
While kissing, through saliva, as the concentration of virus in saliva is insufficient for transmission. In the history of the study of HIV/AIDS has not been a single case of infection this way.
HIV protected sex
So to prevent HIV infection. There is a very straightforward and affordable way to keep the health of yourself, and your partner is safe sex.
Safe sex is sex in which eliminated the ingested someone else's blood, semen, or vaginal secretions.
This means that you can kiss, lying together, hugging, caress and massage each other.
However, if you commit penetrative sexual intercourse, you should always use a CONDOM.
It should be borne in mind that some STIs can be transmitted through contact with mucous membranes. Therefore, when you engage in oral sex also need to use a condom and latex pad (which is to be cut along a condom, or even food wrap).
You must know that when sharing dildos, it is also the possible transmission of HIV and STIs. Therefore, these contacts should always be protected by a condom - separate for each partner.
Safe sex is the surest way of preventing HIV/AIDS and other sexually transmitted infections. It is also a convenient and secure method of family planning because the use of a condom solves another important problem - prevention of unwanted pregnancy.
