What is Nipah Virus?

Nipah virus (NiV) infection is a newly emerging zoonosis that causes severe disease in both animals and humans. The natural host of the virus are fruit bats of the Pteropodidae Family, Pteropus genus. Here are a few facts about the virus

  • The natural host of this virus is believed to be fruit bats of the Pteropus species, four of which have been demonstrated to have serologic evidence of infection with this virus. The virus has also been isolated from fetal tissue and uterine fluids of these bats.
  • Nipah and Hendra viruses are two related zoonotic pathogens that have emerged in the Asia-Pacific region. Both are RNA viruses that belong to the Paramyxoviridae family.
  • The viruses jump the species barrier and infect a secondary animal host (eg, pigs or horses), and transmit infections to humans. In addition, the Nipah virus may be able to spread from human to human.
  • Nipah virus primarily causes an encephalitic syndrome with a high mortality rate. The characteristic MRI abnormalities are multiple, small (less than 5 mm), asymmetric focal lesions in the subcortical and deep white matter without surrounding edema.
  • The incubation period ranges from 7 to 40 days. The initial presentation is non-specific, characterized by the sudden onset of fever, headache, myalgia, nausea and vomiting.Meningismus is seen in approximately one-third of patients although marked nuchal rigidity and photophobia are uncommon. Patients infected with Hendra virus have presented with fever and influenza-like illnesses, or with meningoencephalitis.
  • The diagnosis of Nipah virus can be established using an Enzyme-Linked Immunoassay (ELISA).  Supportive care is the mainstay of treatment and infected patients may requireintensive care monitoring.
