Abstract

Viral infections of the CNS in the tropics and Indian subcontinent are not only different from that encountered in the western world, but many types are constantly emerging. While age-old scourges like polio have recently been contained in these geographical areas to a great extent, thanks to effective vaccination programs, others like Japanese encephalitis, rabies, and measles in the form of subacute sclerosing panencephalitis have been inadequately controlled. In recent times some viruses causing predominant CNS symptoms such as West Nile, Chandipura, and Nipah have emerged. Emerging viruses also include others that may occasionally cause CNS symptoms such as enterovirus, dengue, and chikungunya. The CNS manifestations of most of these viruses may be in the form of aseptic meningitis, encephalitis, or myelitis either in isolated form or in combination. Many of these viruses such as Japanese encephalitis cause large-scale epidemics with high mortality and morbidity. This chapter discusses the current status of many of these viral infections of the CNS predominant in these geographical areas.
