Those things must be gold mines for genes. I only recall learning that a dozen transcription/translation targets were packed into a virus.

HIV is an enveloped virus. This means that the core of the virus, which contains the genetic information, is wrapped up in an oily layer. Sticking out of this oily envelope are the "receptor" molecules that are used by the virus particle to attach to - and infect - target cells.
What is the oil made of?QuoteThe envelope is stable only in an aqueous (watery) environment. This means that while it is in blood the virus remains viable. But transferred to an external surface, which will dry out, the virus will also dry and the envelope will be disrupted. When this happens the receptors upon which it depends for infectivity will also be disrupted and hence the virus is incapable of infecting.
How does an oily virus gain access to an aqueous environment when oil and water don't mix?Quote
At the same time, in the environment the virus is exposed to ultraviolet rays which chemically destroy the nucleic acid (RNA) that comprises the viral genomes (each particle has 2 copies of its genome). This mutates the virus out of existence, further reducing viability.
How can a virus which is dead by ultraviolet light can infect other people at the same time?
Of course the earth is flat... there is so much here to prove it......
