2-15. PATHOGENIC VIRUSES
Table 2-4 presents a list of the principal viral diseases of public health importance, grouped according to the physiological manifestations, the type of tissue attacked, or the similarity in the infective virus. These groupings are quite arbitrary, in that not all authorities classify these diseases in the same way.
