It is very unlikely to transmit/contract the HIV virus in this manner. The "scratcher" could only plausibly do so if there is an open sore(s) under his/her nails, or abrasions caused by violent fighting back and forth. This however is even less likely since the HIV retrovirus is not viable for very long outside of the bodily fluids (esp. blood.) Although it is a bit of a fighting point between caregivers and researchers, it is likely that the virus is rendered noninfectious when it comes in contact with the air.
If you are asking because of a personal incident or a similar event a friend of yours encountered, and the person is known to have HIV, It still would be the best choice to get tested (getting tested periodically is a good idea anyway). But it is very unlikely that HIV was transmitted in this manner. I don't believe there are any documented case where a similar route lead to an infected individual.
The only way HIV can be transmitted is if the fluids of an HIV infected person come into contact with the fluids of a person who is not infected.
A mere scratch will not result in transmission of the virus, particularly if the skin is not broken and the person doing the scratching is not HIV positive.
In order to pass on HIV from an open wound there would have to be a transmission of bodily fluids from one person to another. Simply touching a scratch or wound would not lead to an infection, the skin acts a barrier preventing liquids, including blood from 'seeping' into the body. Even when HIV infected blood comes into contact with broken skin of a negative person transmission is unlikely. In the very small number of documented cases where this has occurred there have been significant quantities of blood involved in the transmission, e.g. from a serious accident.
Other factors are also relevant: someone living with HIV would need to have enough virus in their blood (viral load) to be able to pass it on to another person. Typically this would be someone newly infected (and they may not know this is the case) or someone who is not yet receiving antiretroviral drugs.
The development of opportunistic infections marks the transition from HIV to AIDS.
The scratch marks on rocks left by moving glaciers are called glacial striations. These marks are typically parallel and indicate the direction in which the glacier was moving.
Yes
It certainly is possible to scratch it, but this stand is scratch resistant and won't scratch easily - but almost nothing out there is really "scratch proof". Generally, no it won't scratch easily.
Most scratches from fingernails leave red marks where the scratch occurred.

The HIV (the AIDS virus) is transmitted through blood and bodyfluids. If you scratch a HIV+ person so s/he starts to bleed and you get that blood into your bloodsrtream through an open wound, cut or similar, you may get Hiv. But it is important to know that unless blood is transferred from the HIV+ to your blood there is no danger of being contaminated. Yo can hug, drink of the same teacup, eat from the same spoon etc without any risks. If you on the other hand is speaking about an HIV+ person scratching you ( as in a fight) there are no risk at all Unless the other person was bleeding.
So small the chance does not even exist. There has to be a trasmission of body fluid which is not likely to occur via scratching.
Yes, just don't pick at them.
Uh, maybe. If everybody is OK with it.
Yes. But it is most unlikely to happen.
