What is Nipah Virus?

Nipah virus is a dangerous zoonotic virus that spreads from animals to humans. Fruit bats are considered the main carriers of the virus. Infection may occur through contaminated food, infected animals, or close contact with infected individuals.

The virus can cause:

• Fever

• Headache

• Breathing problems

• Drowsiness

• Brain inflammation (encephalitis)

Health experts say the fatality rate can range from 40% to 75%, depending on the outbreak and healthcare response.

Current Situation in India

First West Bengal Outbreak in 19 Years

This is the first Nipah virus outbreak reported in West Bengal after nearly 19 years. Earlier outbreaks in the state were recorded in 2001 and 2007.

International Monitoring Increased

Following the reports, some Asian countries temporarily increased airport screening for travelers arriving from India as a precautionary measure.

WHO Assessment

The World Health Organization (WHO) has assessed the global public health risk as low. Officials also confirmed there is no evidence of sustained human-to-human transmission at this time.

Precautions and Safety Tips

Health authorities have advised citizens to follow these preventive measures:

• Avoid drinking raw date palm sap or toddy.

• Do not eat fruits partially eaten by bats.

• Maintain proper hand hygiene.

• Avoid close contact with people showing symptoms like fever or breathing difficulty.

• Follow official health advisories in affected areas.

Early medical attention is important if symptoms appear after exposure.

Japanese Encephalitis (JE) Update

Separately, Japanese Encephalitis (JE) cases continue to appear seasonally in states like Assam, Uttar Pradesh, and nearby regions, especially during the monsoon season.

Health experts recommend:

• Vaccination

• Mosquito control

• Clean surroundings

• Use of mosquito nets and repellents

These measures can help reduce the spread of JE infections.

Government Response

The Union Health Ministry is continuously monitoring emerging health threats across the country. State health departments, surveillance teams, and hospitals remain alert to prevent any further spread of infectious diseases.

Citizens are advised to rely only on official government and WHO updates instead of rumors or unverified social media posts.
