Hello! How are you? Today we are going to talk about a disease that we have not heard of, but it is good to know about. We all know that ticks, although they are small animals, can transmit various diseases. Maybe you have heard of diseases like `(Lyme disease)`. But this Powassan virus disease that we are talking about today is much rarer. But even though it is rare, it is worth being a little aware of it, right?
What is this Powassan Virus disease?
Simply put, this is a disease caused by a virus . This virus enters our body when an infected tick bites us. Remember, not all ticks carry this virus. But some ticks may be infected with this virus. Such a tick is the one that spreads this disease.
You may have heard of another tick-borne disease called `(Lyme disease)`. It is a little more famous than this one, because it is a little more common. But this Powassan virus disease is a very rare disease. There are no such large reports in Sri Lanka at the moment. However, it has been reported in some countries of the world, for example, Canada, the northern provinces of America, and Russia. Therefore, if you are a person who travels to such countries and spends a lot of time outdoors, it is good to know a little about this.
What symptoms might occur if this disease develops?
Okay, now let's see what symptoms this Powassan virus can cause. The important thing is, not everyone gets symptoms . Some people can get this virus and not show any symptoms.
However, if symptoms do appear, they usually start within a week to a month after the tick bite. They may include:
- I'm getting a high fever .
- My head hurts badly.
- Vomiting .
- The body may feel very lifeless , and sometimes the mind may feel confused , meaning that the mind cannot focus.
- Some people are prone to having fit-like conditions (seizures) .
- Forgetfulness , which means memory loss, can also occur.
- In more serious cases, brain-related problems can occur. This includes:
- Meningitis : This is an inflammation of the protective membranes that surround our brain and spinal cord. It's like a brain flu.
- Encephalitis : This is a direct swelling of the brain. This is also a very dangerous condition.
Just because you have one or two of these symptoms, don't be afraid to assume that it's Powassan virus disease. After all, how many other illnesses can cause fever and headache? However, if you've been in an environment where ticks can live, and you have more than one of these symptoms, it's best to see a doctor.
As I said before, this disease has been reported most often in countries like Canada, the northeastern regions of the United States (Great Lakes region), and Russia. So, people who spend a lot of time outdoors, in forested areas, and on farms in such areas are more likely to develop this infection.
How does a doctor diagnose a Powassan virus infection?
Now you might be thinking, 'Okay, I have these symptoms, I've been in an area where there are ticks, now how do I find this exact one?'
Here's what usually happens: When you go to a doctor, they 'll ask you about your symptoms . They'll also ask you if you've been in an environment with ticks recently, or if you've been bitten by a tick.
Based on this information, if the doctor suspects that this could be a Powassan virus infection, he will order several special tests .
The main thing is to take a blood sample and send it to a lab to see if this virus is present in the body.
Sometimes, especially if there are symptoms related to the brain (such as meningitis or encephalitis), doctors may do another test. This is called a 'cerebrospinal fluid' (CSF) test . This 'CSF' is the fluid that surrounds our brain and spinal cord inside the spine. To get a sample of this fluid, a small sample is taken from the spine using a procedure called 'lumbar puncture' . Some people also call this 'spinal tap'. This test can clearly detect whether there is an infection in the brain.
So, it is through tests like this that we can accurately confirm whether this is a Powassan virus infection or not.
Is there a treatment for this Powassan Virus disease?
This is a question that many people ask. 'Is there a cure for this? Can I get better quickly?'
To be honest, there is no specific medicine for this Powassan virus infection, that is, there is no medicine designed to destroy this virus . That is, like dengue, there is no special medicine to kill this virus.
What do you do then?
If the illness is not that severe and you only have mild symptoms, you can recover by resting at home and taking the medicine prescribed by your doctor to reduce fever and relieve aches.
However, if the infection is serious , such as the one I mentioned earlier, if the brain swells (encephalitis) or the membranes around the brain swells (meningitis), you will definitely need to be hospitalized and treated .
What are you doing at the hospital?
- They give medicine for headaches and vomiting.
- If the body is dehydrated, intravenous fluids (IV fluids), such as saline, are given .
- If the condition is very serious, meaning if there is difficulty breathing or if consciousness is impaired, then treatment is provided in the Intensive Care Unit (ICU) .
- If there is swelling in the brain, special medications will be given to reduce it. Also, machines may need to be used to help with breathing.
The important thing is that all of these treatments are designed to control symptoms and help the body heal . It is our own immune system that is supposed to fight and defeat the virus. What doctors do is help the body in that fight.
Can we survive this Powassan Virus disease?
Well, after talking about treatment, what's even more important is to stay safe from this disease. Because, as with any disease, 'Prevention is better than cure', that is, it is better to take care of the disease before it develops than to treat it after it has developed.
The best and only way to prevent Powassan virus disease is to avoid ticks . This disease is transmitted through the bite of an infected tick. So if you reduce the chances of a tick coming into contact with you, you can also stop the disease from developing.
Be especially careful if you're going to forested areas, farms, grassy areas, or anywhere you think ticks might be present:
- Dress as much as possible to cover your body . This means wearing long pants, long-sleeved shirts, and closed shoes or boots.
- Keep the legs of your pants tucked into your shoes or boots . This will reduce the chance of ticks crawling up your pants.
- Try to wear light-colored clothes . Do you know why? If a small animal like a tick is on light-colored clothes, it will easily catch your eye. They are harder to find on dark-colored clothes.
- If your hair is long, tie it up tightly or wear a hat . This can also help prevent ticks from getting on your head.
- When outdoors, especially on grass, don't sit on the ground . It's better to use something like a chair.
- Use an insect repellent . These are available at the store. When buying, look for a chemical called DEET (N,N-diethyl-meta-toluamide) that contains 10% to 30% of the chemical. DEET is a substance that repels ticks and mosquitoes. However, when using these, you should follow the instructions on the bottle exactly, especially if you are using them on young children.
- Always check yourself and your family for ticks when you are outdoors and after you return home. Pay special attention to areas where there are skin folds, such as the armpits, groin, scalp, behind the ears, and behind the knees.
- Don't forget to check your pets too . Ticks on them can spread to other people in your home.
One more thing, it's also very important to know how to properly remove a tick . If you suddenly find a tick attached to your body, don't just pull it out with your hands. There is a proper method for that. Be aware of that too.
Things we need to remember
Okay, so I hope you now have a good understanding of the Powassan Virus we talked about today. Finally, let's remind ourselves of these important points:
- First of all, this is a very rare disease . So there's no need to panic. But it's worth being aware, especially if you're traveling to areas where ticks are common.
- Secondly, the best way to protect yourself from this disease is to avoid ticks . It is very important to follow the safety measures I mentioned earlier.
- Third, if you suspect you have been bitten by a tick, and if you develop symptoms such as fever, headache, vomiting, or weakness, be sure to see a doctor immediately . Explain the situation to the doctor and get the necessary tests done.
- Although there is no specific treatment for this, supportive care is provided by hospitalization depending on the symptoms . So do not panic and follow the doctor's instructions.
Remember, being aware of these diseases isn't just about scaring us. It's about understanding how to protect ourselves, what to do if a problem arises, and helping us live healthier lives.
Wishing you all good health!
