Simulating an epidemic

Never took VARIANTS (of viral expression) into consideration in relation to 'travelling', especially if he means 'overseas'.

Different things happen geographically in relation to evolution of virus generation (which seems to have a connection to solar cycles , in particular 'solar maximum and minimum'.) Pubmed has some material of this nature.

Oh，it's such a useful video

Never thought this video would be extremely useful in uni
Thank you 3b1b
Amazing video

Where can we find instructions on how to do each experiment?The link doesn't work.

Is there a worksheet that goes along with this that I can use in the classroom

What about 99% or 95% of the population doing the social distencing, would it eradicate the disease or keep spreading ?

can you do a 3d model of the simulation ? amazing work !

Interesting

Hi. Did you use agent based models to simulate this?

This gave me so much needed mathematical perspective for foreign and domestic policy. Very interesting

Theres no such thing as a Virus!

This reminds me of the simulations that Primer would run.

But the ones that have recovered can get infected again after a while. Why dont consider this?

After watching this video again, I am curious how the regulations of the government (in the Netherlands, for example) would look like in these models. as an example: that you start with the standard situation and then implement hygiene and social distancing. then the quarantine, vaccine and reopening of social destinations. all in the order of the regulation that took place and then put that model next to the observed data.

would it be possible to show me how you coded these?

this has aged really, really poorly lmao

Thank you very much. 😊

China took some inspiration

This video inspired me to make my own infection code on Khan Academy.

I guess removed can mean two things, you got immune or you are dead. And that is solely up to the type of virus and how it works. Great explanation!

Could you do a follow-up that includes animal reservoirs as a method of incubation and its possible effect on proliferation? Or the odds that a portion of the population would not be immune after contracting the virus, therefore not placed into the "recovered/removed" category? Mutations that make immune people susceptible again? My gut feeling is that those factors would effectively result in an inability to ever fully eradicate it.

A virus is God's way of telling you idiots that you're going about your business wrong. You reap what you sow including the irony of not being able to recognize the solution.

Nice model. It is overly simplistic and incomplete. It applies to every virus regardless of severity. It doesn't take into account the way our immune systems actually work or the way viral load factors into something being an outbreak vs an endemic spread of a mild contagion, and it doesn't model how a relatively mild virus spreads in population of people with robust immune systems who aren't afraid of germs. Using models like this to justify infringing on people's rights is a dangerous game and I hate everything about it.

Gotta ask, what say you now? Bahahaha

Solution: Replace your assumed value (= guess) for P (probability of infection by being in a certain radius of a so-called 'infectious' person ), by my assumed value, 0 (zero)

It's too bad people aren't exactly the same and have different immune systems to handle the problem

Gotta love the people in the comment section that now think that mathematics itself is a Jewish conspiracy just so they can hold onto their crazy beliefs. Either these people don't remember what they say in-between clauses, or they don't care about truth in the slightest.

Anyway, really interesting vid.

i love how the 50 percent social distancing is literally just america

looking through this video and i see all the things we did wrong. but couldn't prevent. 1. not every social distanced. 2. people need food and water thus stores had to stay open. (yes we had rules in effect to try and slow/prevent infection but that doesn't mean much when an infected person walks in coughing up a storm without any prevenitive measure in place) 3. Testing was to broad you could have been infected and already passed the effects but still test positive from it. (i heard it was 9 months) and alot of other things as the news got old and people just stopped caring.

There needs to be a component where during social distancing the rate of other diseases increases and so does suicide so that is relevant to the removed or dead component .

Australia saw the isolation box, and was like, hold my beer.

Uh

Thanks for this video!

I hate how generalized this algorithm is. Each action is infinitely complex, having variable we do not know. I wish you would have done a better job of demonstrating the actions one takes to infect, remove, or move around.

I remember watching this two years ago and getting to the part about how letting up quarantine too early just causes a second, possibly larger, wave and thinking "Oh. That sounds horrible." As it turns out (two years later) I was right. That is completely horrible.

2022 and MANY people cheated on lockdowns. Very similar to your simulation. :(

covid won.
