HIV - Transmission and prevention

HIV is found in blood, semen / sperm, vaginal fluids and breast milk. Therefore, it can only be transmitted from person to person when one of the four types of fluids on HIV enters a person is inside the body of an uninfected person ...
How is HIV transmitted?
The easiest path of infection when the virus is HIV-infected people go directly into the bloodstream of the uninfected. For example, using and sharing needles with infected people or cylinder through a blood transfusion with HIV.
HIV can be transmitted through sexual behavior. Sex acts anal unprotected sex with HIV / AIDS spread most easily. Rectal mucosa are fragile, easily scratched or damaged when having anal sex. This time the damage will be opening for the type of STI (diseases transmitted through sexual contact) and HIV in the semen of the blood enters another person - in the case of two people having sex without protection defense. Sex anal therefore at risk of HIV infection and STI. The recipient of semen in the anus relations at risk than people.
Next is the relationship unprotected vaginal. Although lower than the risk of anal relations but relations vaginal HIV transmission is most common in the world. Chance of an HIV-infected men transmit HIV to uninfected female partners is greater than vice versa because the vaginal mucosa in women, where the virus enters the body has a larger area and vulnerable trade than the rules of the penis.
The probability of spread through oral sex is much lower. There was some evidence that HIV can be transmitted through oral sex but this possibility is very small. The infection can only occur when there are bleeding gums or mouth injuries, and disease risk in people who receive higher. However, these other STI such as chlamydia, gonorrhea, herpes and syphilis are easily transmitted through oral sex.
HIV is also spread from mother to child HIV-positive during pregnancy, at birth or through breastfeeding.
Will the HIV infection?
No known cure for HIV. This is why HIV prevention has become extremely important. So do not do anything to HIV infection:
No sex (vaginal intercourse, oral, anal). This is a method quite effective HIV prevention. But for many people this is not a viable solution because sex is part of life.
If your sex life needs:
- We fish from both sides (both do not know for sure when infected with HIV). Fidelity which is a virtue that Vietnam was the constant attention. Even without considering the ethical aspects can also be seen as a faithful bring many benefits. In modern times, faithful not only protection but also happiness can protect human health. If a spouse or lover, the more you should value more the faithful.
 The HIV transmission.
- Use a condom for each sex: condoms can be considered a "bodyguard" if we used condoms and used properly. It helps us avoid HIV and many other problems, including diseases transmitted through sexual contact. The simple reason that most need to use condoms is that we can not know other people have HIV or not, even HIV-infected persons most likely did not know they are infected. So if you have sex, remember one very important thing is: You can ensure that no HIV infection by always using a condom.
- Do not share needles or cylinders (if you are injecting drug users).
The behavior for HIV infection
- Kiss and hug: This behavior does not make the virus from blood or semen of infected persons entering the other person's body is.
- Mosquito bites: HIV does not survive long outside the human body. Besides mosquitoes do not suck their blood and release into the body of the other - they suck blood and "digested" blood. "H-Human" in HIV means "people". Thus the virus can only survive in the human body only.
- Shared bath with HIV: For fluids of infected persons can not enter the body through the tub is not infected.
- Sharing toothbrushes with people infected with HIV: Almost never happen HIV infection by sharing household items. HIV can not survive long outside the human body. After leaving the body of the people infected, the virus must find a way into the body to live another day - this can not happen without sex or sharing needles used.
- Sharing of razors and other sharp items: In theory, if there is fresh blood to stick sharp instruments and soon after this device is a non infected person use or risk being stabbed immediately infection can occur. But in fact, no one has been infected this way. But to be safe we ​​should recommend that people infected do not share razors with other people.
- The normal contact other: all types of casual contact such as eating together, even shared clothes, shared swimming pool, in the same house, sharing a bed (of course not sex), as agencies work together, sharing toilets, hair cut ... does not make anyone infected with HIV.
