WHAT IS NIPAH VIRUS?
Nipah Virus Infection is a new type of infection that is transmitted from animals to humans. This type of infection is called as Zoonosis. Fruit bats of the Pteropodidae family are the natural host of Nipah virus.
a) First identified in the year 1999 in a small Malaysian Village called as Nipah
b) Several Outbreaks in West Bengal from 2001 to 2018

A COMMUNICABLE DISEASE?
Yes, Nipah virus infection is communicable. The virus spreads from animals to humans, especially bats and pigs. Bats easily infect the fruits on trees and the raw date palm sap usually tapped from trees. The virus spreads through the saliva, urine and excreta of the infected bats to the fruits and the raw date palm sap. If humans eat the infected fruit or the infected raw date palm sap, they naturally get infected. Consequently, the infected humans might easily spread the Niah virus to other humans.
According to World Health Organization (WHO), “there is no treatment or vaccine available for either people or animals. The primary treatment for humans is supportive care.”
Nipah Virus infection easily may kill people because of its fatality risk of 10-75%. Nipah Virus undergoes through an incubation period of 4 to 18 days. And the symptoms may show up any time between 3 and 14 days.
Nipah virus infection in humans causes a range of clinical presentations, from asymptomatic infection (subclinical) to acute respiratory infection and fatal encephalitis.
Human respiratory and central nervous system are easily affected by Nipah virus infection. The virus has the potential to pass through the blood-brain barrier ad can be found in the brain and spinal fluids, resulting in encephalitis and brainstem dysfunction. Persistent convulsions and personality changes are also observed.
