Viral infections of the central nervous system or neurotropic viruses are often lethal. Understanding of these diseases involves understanding the interaction between the nervous system and the immune system. This book provides in-depth information about each individual virus, the diseases they cause, and the mechanisms of spread of those diseases. Addressing both clinical and basic science aspects, the text covers such diseases as polio, measles, rabies, herpes, West Nile, Japanese encephalitis, and varicella-zoster. The authors also include detailed discussions of molecular pathogenesis and host pathogen immune interaction as well as disease detection, treatment, and prevention.
