It usually is transmitted directly to humans from birds in their saliva or feces. It is very rare to begin with in humans and only rarely is transmitted from human to human. Birds transmit it to each other in feces and saliva and direct contact.
One human disease caused by an RNA virus is influenza, which is transmitted through respiratory droplets. One human disease caused by a DNA virus is herpes, which is usually transmitted through direct contact with infected lesions or through sexual contact.
Yes, Lymes disease can be transmitted trough contact with blood, for it is spread through the Deer Tick, which is a blood sucking insect that carries the disease . Because of this, it can be transmitted trough the blood, but not other bodily fluids.
If an animal carries a disease, it can be transmitted to a human through saliva, bite or scratches. These diseases include: avian influenza, rabies, E. coli, giardiasis, lyme disease and many more.

Xenozoonosis is an infectious disease transmitted from animal to human by transplantation of animal tissue into a human body.
HPV spreads by human to human contact. There are about 120 different kinds of HPV viruses. About 40 types are transmitted through sexual contact. The rest are transmitted skin to skin contact and both produce what we call warts.
"A vector is an animal, insect, or living organism that can carry and transmit communicable diseases to humans. The abatement or proper handling of vectors is important to the prevention of human illness." - http://www.yolocounty.org/org/Health/eh/general/bitesandvectors.asp#vector Therefore, a bat, a skunk, a dog or whatever animal carrying rabies is a vector... meaning rabies (a communicable disease) is a vector transmitted disease.
AIDS (Acquired Immune Deficiency Syndrome) is not an infectious disease. AIDS is a diagnosis given to HIV+ patients when they exhibit certain clinical criteria. HIV (Human Immunodeficiency Virus) is the virus that causes AIDS. HIV is transmitted through contact with infected blood, semen, vaginal fluid or breast milk.
If I'm understanding your question correctly, then the answer is no. HIV can only be transmitted when the bodily fluids (not saliva) of an infected person comes into contact with your blood. So via sex, or sharing needles/infected needles.
Lyme Disease is transmitted to a human through a tick bite if the tick is carrying the spirochete, Borrelia burgdorferi. The tick transmits the spirochete which causes the disease. It is most commonly found in the brown deer tick.
