A virus is a tiny, irresistible microorganism that replicates life within living cells. a toxin is an atom or molecule created by microbes that is poisonous to target cells or living things. It is usually a big protein.
Because viruses don't appear to be designed to produce toxin-like chemicals, any toxin-like activity must be traced back to the virus's molecule or a piece of it. The similarities are primarily with bacterial endotoxins, which are produced by the wM1 bacterial cell, rather than exotoxins, which are produced by microscopic organisms, critters, or plants.
According to current studies, only the rotavirus is capable of releasing poisons. It creates NSP4, an exotoxin that is only found in the intestines.
