hiv transmission through small blood events

[MateKing]

Hello,
For sure below questions are not new, but there are many places in net where are some doubts and different answers etc.

1. Can hiv be transmitted by other way than sex or injection drugs equipment. If yes in which conditions? (If yes, are available any confirmed evidences of that?)
2. Can hiv be transmitted through blood to blood contact but when is no massive exposure of blood (I mean that infected blood on the skin of one person touch other's one wound but blood is not interted in body by any equipment like syringes etc.)
For example handshake when two people (one is positive) have small open wounds with small blood and is the contact of these wounds.
3. Can hiv be transmitted throught air (just a tiny bloody splash to damaged mucous membrane or skin)? If yes, could it also be done by dried blood as dust?
4. Can hiv be transmitted throught object (or animals etc.) contamineted with small amount fresh blood but with no direct contact with infected person (the contact with fresh blood is after few seconds)?
5. Can hiv be transsmitted through skin rush, ezcema or papercuts?
6. Can hiv be transmitted at hair salon by clipper or scissors?
7. Can hiv be transsmitted with invisible amount of blood?

Thanks,

Thanks for your answer.  But, are any documentation refers to that there are ony 4 transsmission modes? Are all new transmissions from the world be connected with these four ways and no other case were documented in the history?

Your situation is straightforward, so reread the advice because you must be too anxious to understand it.

Agree.  As long as you don't have unprotected vaginal or anal sex or share IV drug needles, you are not at risk.  The HIV virus is quite fragile and is inactivated in air and saliva.

When you talk about HIV transmission, remember it is transmitted through

1. Unprotected anal and / or vaginal sex
2. Sharing works (needles/syringes) in drugs
3. From mother to child
4. Transfusion of blood without screening. (this is not a threat any more in the developed world)

There is no other mode of transmission, therefore no point in going point by point of your post
