The Nipah virus is a silent threat from animals to humans that can be fatal.

In an era where emerging infectious diseases occur worldwide, Nipah virus is one of the viruses that the World Health Organization classifies as a high-priority disease for surveillance. Although outbreaks are rare, it is a disease with a high mortality rate and currently has no specific treatment or direct vaccine available.

 

This article will introduce the Nipah virus, including its origin, transmission methods, symptoms, and prevention strategies to increase awareness and reduce daily life risks.

 

What is Nipah virus?

Nipah virus is a virus in the Henipavirus group, first identified in 1998 during an outbreak in Malaysia. Fruit bats are the natural reservoir of the virus. This virus can be transmitted from animals to humans and from human to human. Nipah virus can cause acute encephalitis and respiratory failure. Without proper care, it may lead to death.

 

How is Nipah virus transmitted?

Nipah virus infection can occur through several routes, including:

     ๐  Contact with secretions from fruit bats such as saliva, urine, or feces

     ๐  Consumption of contaminated food, such as raw date palm sap or fruits bitten by bats

     ๐  Contact with infected animals, especially pigs and horses

     ๐  Human-to-human transmission through secretions such as saliva, sputum, or blood

 

Symptoms of Nipah virus infection

Symptoms appear within 4–14 days after exposure, ranging from mild to severe.

 

Early symptoms

          ๐  High fever

          ๐  Headache

           ๐  Muscle aches

           ๐  Fatigue

          ๐  Sore throat

Severe symptoms

          ๐  Difficulty breathing, severe cough

         ๐  Lethargy, confusion

          ๐  Seizures

          ๐  Encephalitis, unconsciousness, or coma

          ๐  The reported mortality rate from Nipah virus ranges from 40–75%, depending on the strain and healthcare system readiness

 

Diagnosis and treatment

Diagnosis requires specialized laboratory tests such as viral genetic material detection (RT-PCR) or antibody detection against Nipah virus in blood or cerebrospinal fluid. Currently, there is no specific treatment or vaccine for Nipah virus. Treatment is supportive care, including:

    ๐  Controlling fever and seizures

     ๐  Managing respiratory function

     ๐  Close monitoring for neurological complications

 

How to prevent Nipah virus in daily life

Although it is a rare disease, due to its high mortality rate and lack of specific treatment or vaccine, prevention is crucial. The following recommendations are advised:

     ๐  Avoid eating fruits with bite marks from animals

     ๐  Wash fruits thoroughly and peel before eating

     ๐  Avoid contact with bats or sick animals

     ๐  Avoid traveling to outbreak areas

     ๐  Healthcare workers should use appropriate personal protective equipment as recommended

     ๐  If experiencing abnormal symptoms after traveling to risk areas, seek medical attention immediately

 

Nipah virus is a severe zoonotic infectious disease. Although outbreaks are rare, when they occur, they can cause acute neurological and respiratory system damage with a high mortality rate. Currently, there is no vaccine or specific treatment, so care relies on supportive treatment and close monitoring.

 

Prevention is therefore essential, starting from safe food consumption, avoiding fruits or drinks potentially contaminated by bats or sick animals, to observing any abnormal symptoms in oneself. If fever, headache, lethargy, or difficulty breathing occurs after being in a risk area, seek medical attention immediately.
