The emergence of Nipah virus, a highly pathogenic paramyxovirus

Nipah virus first emerged in Malaysia and Singapore between 1998 and 1999, causing severe febrile encephalitis in humans with a mortality rate of close to 40%. In addition, a significant portion of those recovering from acute infection had relapse encephalitis and long-term neurological defects. Since its initial outbreak, there have been numerous Outbreaks in Bangladesh and India, in which the mortality rate rose to approximately 70%. These Subsequent outbreaks were distinct From the initial outbreak, both in their epidemiology and in their clinical presentations. Recent developments in diagnostics may expedite disease diagnosis and outbreak containment, while progress ill Understanding the molecular biology of Nipah virus could lead to novel therapeutics and vaccines for this deadly pathogen.
