Human Immunodeficiency Virus (HIV) is a retrovirus so humans are one species.
They also infect mammals and other vertebrates such as birds and some forms infect fungi and insects. There is also one that infects yeasts.
It is called a Retrovirus HIV is an example of a Retrovirus
No. Though measles contains an RNA genome like retroviruses, it does not have the distinctive enzyme reverse transcriptase, and therefore does not change its genome to DNA before transcription.
Yes, viruses can mutate to infect new species.
Yes, they do.

A pandoravirus is any of a species of very large viruses which infect amoebas.
Aids/ HIV is actually caused by a retrovirus. These retroviruses are viruses that uses reverse transcriptase, an enzyme that is used when RNA transcribes into DNA. And then translation of the DNA into RNA, producing the genetic information to produce for retroviruses. This process happens as many times when the retrovirus needs to infect the cell. If a Leech sucks on infected blood, will the leech cure AIDS? No because it wouldn't "kill" that retrovirus.
no
No, the Ichthyophthirius multifiliis parasite does not infect humans. It is a parasite that specifically infects fish, particularly freshwater fish species.
The difference between a common animal virus and a retrovirus is that a retrovirus only contains RNA while a common animal virus will have DNA or RNA.
no
Yes. Some species of infection causing organisms are very particular and only infect one species, or a small group of related species, but there are a few that are much less picky. One example is the virus that causes rabies. Rabies can infect almost anything that's warm-blooded.
