Have you heard of West Nile Virus? Let's talk about it in detail!

You've probably heard of diseases that are spread by mosquitoes. Like dengue. Today we're going to talk about a virus that's also spread by mosquitoes, but it's a little different. It's called West Nile Virus. Some people don't get serious symptoms from it, but some people can get a little sick. So, let's take a look at what this West Nile virus is, how it spreads, what the symptoms are, and how to protect yourself.

What is this West Nile Virus?

Simply put, West Nile is a virus that enters our bodies when a mosquito bites us. Most of the time, most people don't show any symptoms . However, not everyone does. Roughly speaking, about one in five people will experience symptoms similar to a common flu (sometimes called West Nile fever) such as fever, headache, and body aches . Very rarely, this West Nile virus can affect our nervous system, infecting the brain or spinal cord and causing serious conditions (`(Encephalitis)` or `(Meningitis)`).

It is called 'West Nile' because this virus was first discovered in the 'West Nile' district of Uganda.

How common is West Nile virus?

West Nile virus is a virus that is found in many countries around the world. It has been reported in many regions such as North America, Europe, Africa, the Middle East, Australia, and Asia. In fact, it is the most common mosquito-borne virus in the United States . Cases have been reported in all 49 states there. Since the first cases were reported there in 1999, more than 51,000 people have shown symptoms.

What are the symptoms of West Nile virus?

Okay, now let's see what kind of symptoms this virus shows when it occurs. As I said before, not everyone gets symptoms. But let's see what happens to those who do.

Common flu-like symptoms (West Nile fever)

The symptoms that most people experience are similar to a common cold. This is called West Nile fever .

• You may get a fever .
• The headache may be severe.
• The muscles in my body feel like they're hurting .
• Nausea and vomiting may occur.
• Some people may experience loose stools (diarrhea) .
• A skin rash may occur. This is most common on the chest and back.
• Swollen lymph nodes may become swollen.
• You may also feel a sore throat .
• There may be pain behind the eyes .

Serious conditions affecting the brain (West Nile encephalitis and meningitis)

This is the most dangerous and concerning condition . But remember, this only happens to a very small number of people . But it is very important to be aware of these symptoms.

• You may get a very severe, unbearable headache .
• Have a high fever (over 39.5 degrees Celsius, or 103 degrees Fahrenheit) .
• Stiff neck . To the point where you can't bring your chin to your chest.
• Confusion may occur. It may seem like your consciousness is decreasing.
• Muscles become weak .
• Uncontrollable muscle movements (tremors or convulsions) . Like shaking or having a seizure .
• Seizures may occur.
• Paralysis means the loss of a part of the body.
• You can also go into a coma , which means you lose consciousness.

If you or someone you know has any of these serious symptoms, it is essential to seek medical advice immediately .

What causes West Nile virus?

West Nile is a virus that belongs to the group of ``Arboviruses.`` Simply put, ``Arboviruses`` are viruses that infect arthropods - animals with jointed legs, including insects. It is an ``RNA virus`` and belongs to the ``Flavivirus`` family. You may have heard of Dengue fever, Yellow fever, and Zika virus. Those viruses also belong to the ``Flavivirus`` family.

How does West Nile virus infect us?

It is mainly spread through the bite of an infected mosquito . Mosquitoes usually get the virus from an infected bird. (There is no evidence yet that humans can be infected directly from birds.) The virus then multiplies, or grows, inside the mosquito. The virus then enters your body when that mosquito bites you or another animal.

The time it takes for this virus to enter the body and show symptoms, known as the incubation period , is usually two to six days, but can sometimes be up to 14 days.

Very rarely, that is, very rarely, West Nile virus has been reported to be transmitted in other ways. These include:

• From a pregnant mother to the child in the womb.
• Through breast milk.
• Blood transfusion.
• An organ transplant.

Is West Nile virus transmitted from person to person?

This is important. West Nile virus is not spread from person to person . That means you cannot get it from touching, talking to, or touching something that someone who has the disease has used. It is only spread by mosquitoes (except in very rare cases, as mentioned above).

Who is at higher risk of developing West Nile fever?

Although mosquitoes can bite anyone, some people are at higher risk of becoming seriously ill if they get West Nile virus. You may be at higher risk for the following reasons:

• If you are over 60 years old .
• If you are an organ transplant recipient .
• If someone is suffering from cancer .
• If you have diabetes .
• If you have high blood pressure (Hypertension) .
• If you have kidney disease .

What are the possible complications of West Nile virus?

Less than 1% of people infected with West Nile virus (about 1 in 150 people) develop serious symptoms . The most common complication is swelling of parts of our nervous system (the brain and spinal cord). This is called ``encephalitis`` (swelling of the brain) and ``meningitis`` (swelling of the membranes covering the brain and spinal cord).

After a serious West Nile infection, some long-term effects may occur. For example:

• Memory loss .
• Hearing loss .
• Difficulty walking or changes in walking pattern (gait disorders) .
• Muscle weakness .
• Abnormal reflexes .
• Depression .

How is West Nile virus diagnosed?

If you have serious symptoms, your doctor may test your blood or cerebrospinal fluid (CSF) to see if you have West Nile virus infection. These tests are usually only done if you are very ill. If you have symptoms such as swelling in the brain, your doctor may do a CT scan (Computed Tomography scan) or MRI (Magnetic Resonance Imaging) to take pictures of your brain.

How is West Nile virus treated?

Unfortunately, there are no specific antiviral medications to treat West Nile virus. If you have mild symptoms, such as a common cold, you can treat them at home. You can use over-the-counter (OTC) medications, such as pain relievers, just as you would for a common cold or flu.

However, if you have serious neurological symptoms , you will be hospitalized and monitored by doctors. They will treat your symptoms, or they may do things like:

• If you have seizures , you will be given antiseizure medicines .
• If there is difficulty breathing , supplemental oxygen is given, or mechanical ventilation is connected .
• If the body is dehydrated, intravenous (IV) fluids are given.
• Corticosteroids can be given to reduce swelling.
• If you are unable to eat on your own, you may be given food through a tube (tube feeding) .

Can you protect yourself from West Nile virus?

This is the most important part. There is no vaccine yet to prevent West Nile virus . So, the best thing we can do is protect ourselves from mosquito bites . There are a few things we can do to do that:

• Avoid high-risk times : Stay indoors as much as possible during the times when mosquitoes are most active, especially in the early morning and evening, when the sun is setting.
• Use insect repellent : When going outside, spray insect repellent on exposed areas of your body or on your clothes. It is best to choose those that are certified for effectiveness by organizations such as the Environmental Protection Agency (EPA).
• Cover your skin : When going outside, wear light clothing, such as long pants and long-sleeved shirts, to cover as much of your body as possible.
• Remove standing water : Regularly empty and clean any areas where water can collect, such as birdbaths, blocked gutters, and areas where water has accumulated.
• Prevent mosquitoes from entering your home : Keep doors and windows screened, or keep them closed as much as possible.
• Be careful when traveling or sleeping outdoors : if possible, sleep with the windows closed, or use a mosquito net at night to protect yourself from mosquitoes.

Will West Nile virus be cured forever?

Yes, most people's immune systems can fight off West Nile virus and clear it . Mild symptoms, such as a fever, usually resolve on their own. However, if you have a weakened immune system, it may be more difficult to clear the infection. Also, the damage to the nervous system from a severe West Nile infection can be permanent, even if the virus is gone.

How long does West Nile virus last?

Mild symptoms of West Nile virus usually resolve completely within a few weeks . However, in some cases, fatigue and muscle weakness may persist for months. After infection of the nervous system, symptoms such as memory loss, hearing loss, and difficulty walking may be long-lasting or permanent .

Is West Nile virus fatal?

This is a bit scary. About one in 10 people who get the virus will die from the infection. Overall, about one in every 1,500 people who get West Nile virus will die. That means it's only more likely to be fatal if it gets severe .

When should you see a doctor?

If you think you may have West Nile virus, see a doctor right away . He or she can tell you about the following:

• Do you want to take the test or not?
• What are the serious symptoms and how to pay attention to them?
• How to take care of yourself from home.
• When should I see him again?

When should you go to the emergency room?

If you have these serious symptoms, go to the nearest hospital emergency room immediately :

• If you have a very severe headache .
• If you have a high fever (over 39.5 Celsius).
• If the neck is stiff , it is so stiff that the chin cannot be brought to the chest.
• If there is confusion or loss of consciousness.
• If your muscles are weak or you have tremors .
• If you have seizures .

What questions should I ask my doctor?

When you see a doctor, it's helpful to ask these questions:

• How long will it take for me to get better?
• How can I manage my symptoms at home?
• What serious symptoms should I look out for?
• When should I see you again?

Brief points to remember

While mosquitoes are often just annoying, they can sometimes carry viruses that can make us sick. Fortunately, 80% of people who get West Nile virus don't have any symptoms . And for most people, the risk of getting seriously ill from it is very low.

If you are going to an area where mosquitoes are present, it is very important to take steps to protect yourself from them. If you develop symptoms of West Nile virus after being bitten by a mosquito, be sure to see a doctor . He or she can teach you how to watch out for serious symptoms and answer any questions you may have.

Remember, protecting yourself from mosquitoes is the best way to protect yourself from West Nile virus!
