The inner ear (internal ear, auris interna) is the innermost part of the vertebrate ear. In vertebrates, the inner ear is mainly responsible for sound detection and balance. In mammals, it consists of the bony labyrinth, a hollow cavity in the temporal bone of the skull with a system of passages comprising two main functional parts:
In a laboratory setting, HIV has been kept alive for as long as 15 days after the body fluid has dried, but this was controlled at a stable temperature and humidity that would be nearly impossible to reproduce in the natural world.
hiv survival outside of the body -- divergence of opinions. I've seen many people say that the virus dies very quickly when exposed to air but I've found information elsewhere saying HIV can survive for 5-6 days outside the body in room temperature and drying does not affect its infectivity.
