You may have heard this new word in the news these days called 'Nipah Virus'. Some may have been scared. What exactly is Nipah? How does it affect us? Will it affect Sri Lanka too? Let's talk about all this in detail, very simply. There is no reason to be afraid, the most important thing is to be aware.
What is Nipah Virus? Simply put...
Nipah Virus is a virus that can be transmitted from animals to humans . In medical terms, we call it a ``Zoonotic Virus''. It is mainly spread by fruit bats (some people also call them 'flying foxes'). However, it can also be spread by other animals such as pigs, goats, horses, dogs, and cats.
Think of it this way, this virus is like a sneaky person. It has different ways of getting from one place to another.
How does this Nipah virus spread?
There are three main ways this spreads. Let's talk about them clearly.
1. By contact with the body fluids of an infected animal:
This means that if the blood, feces, or saliva of an animal that has the virus enters the body of a healthy person, the virus can enter the body. For example, if someone who works closely with an infected pig touches the urine or saliva of that animal and does not wash their hands properly, they can get the virus.
2. If you eat food contaminated by an infected animal:
Imagine, if a bat with the virus eats a fruit and drops it on the ground, or if something like its urine falls on a fruit, and the fruit is eaten without being washed properly, the virus can be transmitted. In particular, it is said that one should be careful with raw date palm sap and fruits from trees where bats live.
3. By close contact with someone who has the Nipah virus:
This is how it spreads from person to person . This usually happens to those who are caring for the sick person. Because the virus can be spread to others through things like the patient's saliva and droplets from sneezing. That's why special protective clothing is used in hospitals.
The most important thing is that it can also be spread through the air through droplets released when someone with the Nipah virus coughs or sneezes . This means that if we are close to them at such times, those droplets can enter our respiratory system and cause the disease.
Where is the Nipah virus most common?
Nipah virus is mainly found in Asian countries, with cases of the virus reported almost annually, especially in Bangladesh and India .
The virus was first discovered in 1999 in a major outbreak in Malaysia and Singapore . At that time, more than 100 people died and hundreds of thousands of pigs had to be culled. Since then, about 20 other outbreaks have been reported.
Therefore, if you are traveling to countries like Bangladesh, Malaysia, Singapore, and India, you should be especially careful about this. In addition to these countries, there are also bat species that spread this virus in countries like Cambodia, Indonesia, Madagascar, the Philippines, and Thailand, so there may be a risk in those countries as well. Although there has not been a confirmed case of Nipah virus in Sri Lanka, it is very important for all of us to be aware of this.
What are the symptoms of Nipah virus?
After being infected with the Nipah virus, it can take between 4 and 14 days for symptoms to appear. Sometimes this time can be longer or shorter.
The first symptoms that may appear are:
- Fever
- Severe headache
- Difficulty breathing
- Cough and sore throat
- Diarrhea
- Vomiting
- Body aches and extreme fatigue
Often, fever and headache come first. Then, respiratory symptoms such as cough and difficulty breathing appear.
The most dangerous symptoms are those that can occur if the disease becomes severe . This can lead to an infection of the brain (encephalitis) . This is life-threatening.
Other severe symptoms:
- Confusion and memory loss
- Slurred speech (like stuttering)
- Seizures
- Coma
- Severe respiratory distress
Researchers still don't know exactly why some people develop these symptoms so mildly and get better, while others get them so severe. Surprisingly, some people can have the virus but not show any symptoms at all .
How dangerous is the Nipah virus to humans?
In fact, Nipah virus is a virus that can be fatal to humans. According to the US Centers for Disease Control and Prevention (US CDC), between 40% and 75% of people who contract the disease can die . This percentage varies from country to country, and also depends on how prepared health authorities are to control the outbreak.
What causes the Nipah virus?
As we've said before, this is a virus that comes from animals. The first reported cases were people who came into contact with infected pigs. It was later discovered that the original source of the disease was bats, and that the bats were the ones that transmitted the disease to pigs.
Simply put, if an infected bat or pig lets its bodily fluids (saliva, urine, feces, blood) come into contact with another animal, that animal will also get the virus. The same goes for humans. Once a person has the virus, they can pass it on to another person through their bodily fluids.
It is also said to be transmitted through food and drink. That is, it can be transmitted by consuming fruits eaten by animals like bats, or by consuming fruits that have fallen on them, such as their urine and saliva, and date juice. People who frequently climb trees where bats roost have also been infected with this virus.
How quickly does the Nipah virus spread?
Yes, Nipah virus is a contagious disease . It spreads through bodily fluids like saliva, feces, and blood. This means that if you are caring for someone with Nipah virus, you can catch it when that person coughs or sneezes.
What are the risk factors?
The main risk of contracting this virus is contact with infected bats, pigs, and humans in areas where the Nipah virus is prevalent. Therefore, it is very important to stay away from sick animals as much as possible. Drinking raw date juice and eating fruits that have been contaminated by bats are also risk factors.
What are the possible complications of Nipah virus?
Some people may develop long-term complications after recovery. For example , seizures may persist and personality changes may develop. For a very small number of people, symptoms may not appear for months or even years after infection. This is because the virus remains dormant in the body. People who have recovered from encephalitis can have a relapse.
How is Nipah virus diagnosed? `(Diagnosis)`
A doctor may suspect Nipah virus by looking at your symptoms and asking if you have recently traveled to areas where the virus is present. Early in the illness, a `RT-PCR` (Real-Time Polymerase Chain Reaction) test can be used to confirm the presence of Nipah virus. This test usually uses the following:
- Nasal or throat swabs
- Cerebrospinal fluid (CSF)
- Urine samples
- Blood samples
The disease can be diagnosed either in the later stages of the disease or after recovery by testing for specific antibodies in your blood. This is called an ELISA (Enzyme-Linked Immunosorbent Assay) test .
How is Nipah virus treated?
Unfortunately, no specific antiviral medications have yet been found for Nipah virus. This means that treatment is limited to controlling symptoms . This can include:
- Drinking plenty of water.
- To rest well.
- Taking painkillers like Paracetamol or Ibuprofen to reduce fever.
- Using medication for nausea and vomiting.
- Using inhalers or nebulizers for breathing difficulties.
- If you have a seizure, take antiseizure medications.
Researchers are currently studying whether a treatment called `Monoclonal Antibody Treatment` can be used against the Nipah virus, but it is still in the research stage.
Is there a cure for the Nipah virus?
No, there is no vaccine or specific medicine yet that can completely cure the Nipah virus.
Can you survive if you get the Nipah virus?
Yes, there are people who recover from Nipah virus. But, as we said earlier, between 40% and 75% of those who get the disease die . This is a really dangerous situation. The symptoms can range from a very mild fever and headache, to brain infection and even death.
How are we protected from the Nipah virus? (Prevention)
This is the most important part. If you live in an area with Nipah virus, or are traveling to one, it is essential to follow these precautions:
- Wash your hands thoroughly: Apply soap and rub your hands together for at least 20 seconds.
- Stay away from sick pigs and bats.
- Keep pig farms clean and disinfected. Immediately isolate and quarantine animals suspected of having the virus.
- Avoid hanging around trees and bushes where bats roost.
- Avoid eating foods that may be contaminated, especially raw date juice, fruits that have been eaten by bats, or fruits that have been contaminated with bat droppings.
- If you are adding date juice, make sure to heat it well before using it.
- Wash all fruits thoroughly before eating, remove the skin, and eat.
- Remove fruit eaten by bats and fruit that has fallen to the ground.
- Avoid contact with saliva, blood, and other bodily fluids of someone who has the virus.
Infection control measures are another way to help prevent the spread of Nipah virus. For example, if you are caring for someone suspected of having Nipah virus, you should always use Personal Protective Equipment (PPE) .
`PPE` includes:
- Special gowns that can protect against body fluids (Isolation or full coverage gowns).
- Medical gloves.
- Eye protection (like safety glasses or goggles)
- Medical or surgical masks. The type of mask used may vary depending on the severity of the pandemic.
Healthcare workers in hospitals and health centers should follow standard infection control procedures. They should use appropriate disinfectants to clean and disinfect all surfaces.
When should I see a doctor?
If you have symptoms of Nipah virus (such as fever, headache, difficulty breathing), especially if you have recently traveled to a country with Nipah virus, or if you have cared for someone/animal with the virus, see a doctor immediately. Although there is no specific treatment for this, it is important to know if you have the virus to prevent it from spreading to others.
Finally, things to remember (Take-Home Message)
Nipah virus is a virus that can be really dangerous, spread mainly from bats and pigs.
The most important thing is to be aware and safe, rather than afraid.
- The best way to avoid this is to stay away from sick animals , especially in areas where outbreaks are reported.
- Also, avoid foods and drinks that may be contaminated (especially fruits and raw date juice from areas where bats live).
- Since it can be transmitted from person to person, be very careful when approaching someone with the virus and follow the necessary safety precautions.
- If you have recently traveled to an area with Nipah virus and develop symptoms such as fever, headache, and difficulty breathing, seek medical advice without delay .
If we all become aware of these things and take the necessary precautions, we can protect ourselves from these types of viruses. If you have any further questions, don't hesitate to talk to a doctor.
