Nipah Virus is an emerging infectious disease that broke out in Malaysia and Singapore in 1998 and 1999. It has been found among several species of domestic animals. The infection is also known to affect human beings. The organism which causes Nipah Virus encephalitis is an RNA or Ribonucleic acid virus of the family Paramyxoviridae, genus Henipavirus, and is closely related to Hendra virus. Nipah virus infection gets its name from the village in Malaysia where the person from whom the virus was first isolated succumbed to the disease. The disease spreads through fruit bats or ‘flying foxes,’ of the genus Pteropus, who are natural reservoir hosts of the Nipah and Hendra viruses. The virus is present in bat urine and potentially, bat faeces, saliva, and birthing fluids. Typically, the human infection is marked by fever, headache, drowsiness, disorientation, mental confusion, coma, and potentially death.
