the most common and the most believed theory of how HIV came into existence is the " Hunter" theory. in this theory, SIV was given or transferred to humans from chimps when the chimps blood got in a hunters cut or wound or raw chimp meat was consumed by hunters. during those processes, SIV was transferred to a hunter. usually the human body would fight off the disease very easily, but in some cases(depending on the person and the immune system) the SIV would have spread in the body causing strains at first and then leading to HIV then later into AIDS. there has been many bans on the butchering and consumption of ape and chimpanzee meat to stop any diseases like HIV to happen again.
Best educated guess currently - it mutated from a similar disease in monkeys in equatorial Africa, at least 60 years ago - the last I heard was that the first known death was of an English merchant seaman who died of what was an unknown disease at the time, in the 1950's.
How it transferred to man is open to conjecture (some of it pretty colourful), but it may have been via the bushmeat trade.
HIV is a virus that causes AIDS
HIV- Human Immunodeficiency Virus *HIV is not a pathogenic organism, but a virus. To be an organism it must be able to replicate on its own, which it cannot. It needs a host to do so.
No HIV is not bacteria or any other organism. HIV is a retrovirus. It infects the T helper cells of human, cause AIDS disease.No, it is a virus.No, it is not a virus.
HIV cells are not found in plants. Forms of the HIV virus only exist in Primates and Felines.

decibe an organism that can exist only as a group of cells
HIV is the Acronym for Human Immunodeficiency Virus. It is caused by a Virus.
HIV is a virus, and since viruses require another organism to carry out the functions that would classify it as a living organism, it's considered "dead," that is until it finds a host.
It would be an IMAGINARY organism. Sorry- but they do not really exist, so they are not an organism.
No; it does not exist at this time in 2011.
NOOOOO! It can be life threating. It is anything BUT helpful
An organism that only exist as a group of cell is called multicellular organism. It is a living thing that is made of more than one cell.
