Nipah Virus Infection: Findings

Nipah virus Infection: Findings

Scientists detected the presence of IgG antibodies against Nipah virus infection (NiV) in 51 bats that were captured from Karnataka, Kerala, Tamil Nadu and Puducherry.

  • It is a zoonotic virus (it is transmitted from animals to humans).
  • 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.
  • Hendra virus (HeV) infection is a rare emerging zoonosis that causes severe and often fatal disease in both infected horses and humans.
  • It first broke out in Malaysia and Singapore in 1998 and 1999.
  • It first appeared in domestic pigs and has been found among several species of domestic animals including dogs, cats, goats, horses and sheep.
  • 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.
  • The human infection presents as an encephalitic syndrome marked by fever, headache, drowsiness, disorientation, mental confusion, coma, and potentially death.
  • Currently, there are no vaccines for both humans and animals. Intensive supportive care is given to humans infected by Nipah virus.
