Now we know a bit more about how viruses interact with cells, whether those are bacterial cells, or animal cells, such as ours. But how do they gain access to our cells in the first place? How do viruses get inside the human body? Let's take a look at some common routes of viral transmission now.

Alright! Thank you for this. There are so many misconceptions about viral transmission, glad you're educating everyone about it

This is some really good stuff. I find the more I learn from your lectures, the better I am able to critically analyze the constant barrage of information, and I use that term loosely, being put out.

I really liked the video. You have a tendency to clear up foggy subjects so I was hoping you explain for me the differences between day and daytime. Are they interchangeable terms? Nonetheless, keep up the great work.

Thank you! I look forward to your videos and I finally know why naked viruses are hardier than enveloped

@13lacle 4 жыл бұрын

I was also curious about this, but it didn't really give the reason why just that the envelope was required. So I looked it up and it turns out that the functional markers and receptors that recognize the host cell are located on the envelope. Also the envelope is made of glycoprotein and lipoproteins which explains why they break down easier.

Can a virus spread simply through normal breathing like it can from sneezing and/or coughing? The amount of people out there that are completely clueless about how a virus works is too damn high!!!

@apolloandwarrior_3229 4 жыл бұрын

Yea, viruses spread through water droplets in your breath. Ever breathe into a scarf and notice how it gets uncomfortably wet? That's why there's the 6 feet apart as normal breath doesn't spread very far.

No, they probably are flat-earthers or some kind of believers with the similar nonsensical beliefs.

Some people believe that viruses don't exist

@joebedogne3956 4 жыл бұрын

Anti vaxers and such don't believe that viruses are even a thing. Probably one of those idiots.

I don't understand how a virus that does not have any ability to control it's movements ends up connecting to the exact right spot on the exact right cell that it needs to connect to. If a virus is inhaled and then goes to the lungs, how does it find the right spot to attach to on cells in there? Also, after a virus takes over cells and then comes out and spreads to other cells through the blood, I assume, how does the blood carry it to the right place? Do viruses float or sink in blood? Do they get carried by anything in the blood or even blocked by other objects in the blood? How does the corona virus find the ace 2 receptor to attach to on a surface of a cell? Are there many receptors on each cell and does it just accidentally get carried to the ace 2 receptor?

Well it doesn't "find" anything, it just drifts and collides with things, just the way that molecules collide with one another to react.

@Tornadopelt 4 жыл бұрын

There are many, MANY receptors on all cells. How do you think they communicate with each other> And it's not just a single virion of a specific species - in cases with a novel virus (COVID-19, anyone?), or even in known viruses, there can be hundreds or even thousands of virions taken in by the body - the viral dose. These then drift into their target zone, where they bind to the cells' MANY receptors and initiate the infection.

Since almost 4 years I'm looking for a successful experiment where a virus was passed on from one person to another. The latest one the SARS-CoV-2 human challenge from the Imperial College did not even had a control group. Do you know one?

@vegatronld 4 жыл бұрын

Dave is there an oxidizing molecule that or a protein that quickly brakes down the virus? I know that more of a biological processes but just asking .
