Avirusis an ultramicroscopic (20 to 300 nm in diameter), metabolicallyinert, infectious agent that replicates only within the cells of living hosts, mainly bacteria, plants, and animals: composed of anRNAorDNAcore, a protein coat, and, in more complex types, a surrounding envelope. Virus, e...
Many types of infections can cause adenoiditis. It's common to have a respiratory virus before an acute bout of adenoiditis. Viral infections can make infection with bacteria more likely.

It is suggested that these transporters may be part of a larger system of remote communication ('remote sensing and signalling') between cells, organs, body fluid compartments and perhaps even separate organisms. This broader view may help to clarify disease mechanisms, drug–metabolite interactions ...
