Nipah virus infection, an emerging paramyxoviral zoonosis.
The Nipah virus outbreak represented one of several bat-derived paramyxoviruses that has emerged during the last decade to cause severe human and animal disease. The pathogenesis of Nipah infection is associated with its ability to infect blood vessels and extravascular parenchyma in many organs, particularly in the central nervous system. The clinical manifestations of acute Nipah infection range from fever and mild headache to a severe acute encephalitic syndrome in which there is a high mortality. Much remains to be understood about this new disease, including its intriguing ability to cause relapsing encephalitis in some survivors. This review provides an overview of the Nipah outbreak, focussing on what is presently known about it as an infectious disease, including the clinical aspects, pathology and pathogenesis.
