VIRUS
Vi"rus, n. Etym: [L., a slimy liquid, a poisonous liquid, poison,
stench; akin to Gr. visha. Cf. Wizen, v. i.]
1. (Med.)
(a) Contagious or poisonous matter, as of specific ulcers, the bite
of snakes, etc.; -- applied to organic poisons.
(b) The special contagion, inappreciable to the senses and acting in
exceedingly minute quantities, by which a disease is introduced into
the organism and maintained there.
Note: The specific virus of diseases is now regarded as a microscopic
living vegetable organism which multiplies within the body, and,
either by its own action or by the associated development of a
chemical poison, causes the phenomena of the special disease.
2. Fig.: Any morbid corrupting quality in intellectual or moral
conditions; something that poisons the mind or the soul; as, the
virus of obscene books.
