Currently, five confirmed infections have been detected in the West Bengal region, located in the east of the country near Kolkata, the administrative center of the state.
Among the infected are a doctor, a nurse, and a medical facility worker.
The Nipah virus can transmit from animals to humans, particularly through infected bats or pigs. Direct transmission between humans is also possible.
In humans, the virus causes an acute infectious disease. Symptoms include fever, headache, and muscle pain. In the most severe cases, brain inflammation may occur, potentially leading to a coma within two days.
Nipah is classified by the scientific community as a "priority pathogen," indicating its significant pandemic potential.
Lethality from infection ranges from 40 to 75 percent. No specific treatments or vaccines against the virus currently exist.
