程度副詞

as the Corona virus from Wuhan, China continues to spread across the globe, many more are becoming infected and some even dying.

As of making this video, 132 people have died worldwide, with over 6000 infected in China alone.

情態副詞

But what actually happens to your body if you contract the Corona virus now, before we get into it, we want to make clear that this video is in no way intended to spread fear or over sensationalize the severity of the Corona virus.

We won't be commenting on its global threat level because that information is constantly changing while experts monitor its spread.

But what we will be looking at is how the Corona virus actually infects the body, what it does inside of you and then how it causes symptoms spreads how your body actually then fights it off or it causes death in some corona verity are actually an entire family of viruses that cause disease in mammals and birds.

Stars, for example, was also a corona virus.

Now viruses are interesting and that they are sometimes considered both living and non living things.

They aren't made of cells, but they do have the ability to replicate just in a different way than other organisms.

Oh, and they're actually much, much smaller than cells now.

To contract the Corona virus, you first have to come in contact with it, either through an infected person's respiratory secretion.

So a cough or a sneeze through physical contact with them, or by physically touching a surface that the virus is on and then touching somewhere like your nose or melt before washing her hands.

Once the virus is able to enter your body, it's work can begin.

One thing that all viruses have in common is that they carry some kind of genetic material, either DNA or RNA.

In the case of Corona virus it carries are in a, which has all the information the virus needs to replicate.

The genetic information in a virus is typically surrounded by a protective capsule.

You may picture this when you think of a virus, and it is a virus.

But this is a virus that attacks bacteria, also known as a bacterial bash.

In the case of the Corona virus, the RNA is encased in a hell ical captain, and that he local cops.

It looks more like this kind of like the emoji of a virus.

And these projections coming out of the surface or the club like structures are very important for what happens next.

Once the virus comes in contact with your cells, it binds to receptors on that so you can think of the outer layer of the virus like a key.

And if the virus has found the right cells in the right species, its keys are ableto open the lock on these cells.

As a result, the virus is able to enter where now has access to all the cells machinery.

Now, normally, this machinery is reserved for your own DNA, which uses something called the Riva Soames to make proteins that have all sorts of functions and travel all over your body.

But the Corona virus ends up hijacking this system.

It uses its own or, in a to go to those rivals, OEMs and starts making proteins that it wants.

So basically yourself starts producing viruses by making the genetic material by making the caps it an envelope, and ultimately your cell becomes a virus making machine, and this is my viruses are often considered non living because they don't actually have the machinery to do this work.

I actually need your body's cells to do it.

So the Corona virus has its own instructions, read over and over and over and makes protein after protein after protein and ultimately can make millions of viruses.

These viruses eventually fill the cell and make their way back to the cell membrane where they break out, often destroying the cell in the process once it's on to the next cell to repeat the cycle all over again.

Now, as your cells begin to get damaged and die, your body will sense this and start to trigger an immune response.

And both of these things are what will create these symptoms that you begin to feel in the case of the Corona virus.

These symptoms include headaches, running, nose coughing, sore throat and fever, which is part of the reason why it's been so hard to track and understand, because those are common symptoms.

We feel those all the time, especially during flu season.

We're just from getting the common cold medical professionals we need to do laboratory tests on respiratory specimens as well as blood work and blood tests to understand of your symptoms are coming from the Rue Han Corona.

In a healthy individual, the immune system will eventually realize that there's a foreign agent inside your body and mount an attack.

The immune system is incredibly complex, with a plethora of different mechanisms to take down your invaders.

Your temperature increases, which helps your immune system function better and actually makes it a more hostile environment for the virus.

You might create more snot and flem, which make it harder for the virus to attach to your cells and also help to get rid of dead viruses and immune cells.

You may feel weak and tired as your body starts to prioritize fighting off this virus instead of doing a regular day to day activities, and your bones may actually feel sore and a HQ.

And that's because they're actually making more white blood cells for its main line defense.

When the Corona virus is detected, the body triggers signals to start producing antibodies.

These antibodies are created by your own DNA.

There are essentially sections of code in each cell's DNA that contained the instructions of how to build different defense systems enzymes in the nucleus.

Make a copy called messenger or in a, which gets sent to the rhizome in your cells, which will read these instructions and start making the relevant proteins.

With up to 10 million rhizomes in each cell, they become an antibody making factory, which are sent outside of the cell to fight the virus.

The trickiest part for your body is that the immune response doesn't catch the virus right away, so essentially the virus starts with an upper hand.

This is why it can take so long for your body to fight off the virus.

But four Corona virus those with healthy immune system should be able to fight off and rid the body of the virus within weeks.

The problem is primarily for those who have compromised immune systems, which is often people who are elderly or people who are very young.

This particular Corona virus has mostly affected the elderly, and that's because, as we age, our immune systems become less effective and they actually slow down as the virus continues to proliferate and cells continue to die in a desperate attempt to save your body, your immune system can go into overdrive.

In severe cases, white blood cells are responsible for activating a variety of chemicals, which can cause the leaking of fluid into your lungs.

And this combination of cellular destruction from the virus and fluid filled lungs interrupts the transportation of oxygen into the bloodstream, which can lead to suffocation and organ failure.

But the virus isn't always the cause of death, often with a weakened and distracted immune system.

Other organisms, like bacteria, are able to take advantage of the body, causing further complications as organs begin to shut down.

To reiterate it's the immuno compromised that are most at risk and even with that is worth saying that the numbers are relatively low if you think about it.

40,000 people died of the flu in the US alone last year, and over a 1,000,000 people died of heart disease.

On top of that, the death rate right now is being estimated between two and 3% which is continually evolving.

But a disease like SARS was a death rate of 10% and Ebola in some regions has been up to 50%.

All this to say, Don't allow the news to make you panic.

We live in Toronto, where the SARS virus got world scale attention.

That's because the only people who died outside of Asia from that virus were in Canada, and most of them were in Toronto, with only 44 people dying in total.

In Canada, it had a huge impact on our city.

But most importantly, we saw a lot of stigma and racism towards Chinese people.

It's important that we do not repeat those racist notions that happened here in Toronto, when we all need to be aware of this when we talk about the current Corona virus on our social media channels, we have seen lots of people saying things like this always happens in China on relating it a lot to the types of foods that Chinese people eat.

But it's important to remember that Western food practices are what created mad cow disease and also Western meat consumption has created a big issue with antibiotic resistance.

We need to listen to and trust public health professionals, and we need to not overreact and we need to not use this as an excuse to be racist.
