NEW DELHI: Nipah, a rare and often deadly disease which is back in the news with a student in Kerala diagnosed with the infection, is a zoonotic virus which means it is transmitted from animals such as bats or pigs to humans, and can also spread through contaminated food and people-to-people contact.

SIGNS AND SYMPTOMS:
Human infections range from asymptomatic (no symptoms) to acute respiratory infection and fatal encephalitis, involving inflammation of the brain, according to the World Health Organization (WHO).

Infected people initially develop symptoms, including fever, headaches, myalgia (muscle pain), vomiting and sore throat.

This can be followed by dizziness, drowsiness, altered consciousness, and neurological signs that indicate acute encephalitis.

The incubation period - interval from infection to the onset of symptoms - mostly ranges from four to 14 days.

Most people who survive acute encephalitis make a full recovery, but long term neurological conditions have been reported in survivors.

The WHO estimates the case fatality rate at 40 per cent to 75 per cent.

Nipah Virus Signs

24 May, 2018
People are in a state of chaos as the 'deadly' Nipah virus (NiV) is slowly gripping the nation. On Tuesday, minutes before succumbing to the infection, a 28-year-old nurse Lini had shared an emotional letter with her husband, expressing the pain of not being able to see him one last time. She was exposed to the virus while treating affected patients in the Perambra Taluk Hospital, Kozhikode. While the moving note broke our hearts, it's time we take this condition seriously and be extremely cautious about it. Here are the symptoms to watch out for.

PAST OUTBREAKS:

The Nipah virus was first recognised in 1999 during an outbreak among pig farmers in Malaysia.

It was also recognised in Bangladesh in 2001, and nearly annual outbreaks have occurred in that country since. The disease has also been identified periodically in India. Last year, the virus killed 17 people in Kerala.

TRANSMISSION:
During the first recognised outbreak in Malaysia, which also affected Singapore, most human infections resulted from direct contact with sick pigs or their contaminated tissues, according to WHO.

Transmission is thought to have occurred via unprotected exposure to secretions from the pigs, or unprotected contact with the tissue of a sick animal.
