Most viral diseases cause nonsuppurative inflammation with lymphocytes, plasma cells, and monocytes, especially accumulating as perivascular cuffs. A few fulminant viral infections, particularly those that result in considerable necrosis of CNS tissue, are characterized by neutrophil invasion. Neurotropic viruses such as rabies and the arboviral encephalitides destroy neurons so there is neuronal degeneration, satellitosis, and neuronophagia. The rarer “slow‐viral” infections such as Maedi/Visna virus infection may not induce much of an inflammatory response and are slowly progressive.
