The Only Ways The HIV Can Be Transmitted

HIV awareness plays an extremely important role in today’s society. There are a lot of different reasons wherefore you should educate both yourself and your kid. A discussion about drug use and sex might be a little embarrassing for both you and your little one, but keep in mind that sooner or later, they will be exposed to these things anyway. Someone in their entourage will do drugs, just like one of their friends will have sex sooner or later. And when time comes, you clearly do not want your baby to go through this issue without any education at all. This is when big problems show up. So what should you know about the HIV? How is it transmitted?

How The HIV can be transmitted

First of all, the HIV is transmitted through unprotected sexual intercourse, regardless of its nature. Oral, anal and vaginal sex might be responsible for the transmission if one of the partners is infected and not protected. Second, blood is another common way for the HIV transmission. Open wounds should never be exposed to blood contact. From this point of view, all kinds of blood related tools can lead to an unwanted infection – syringes, needles, contaminated medical equipments, tattoo related needles and so on. This is how the HIV is transmitted among drug addicts who share the same syringes and needles. When it comes to getting a tattoo, make sure that the artist uses a brand new needle.

Other than that, the HIV might be transmitted from mothers to their babies as well.
