# Modelling COVID-19 issues

### Project One

![](https://i.imgur.com/OugMCNV.png)



### <span style="color:red">What is the best size $N$ for a lecture? </span>.


<span style="color:blue"> **HINT** </span> Think carefully about how an infection might spread in a well mixed room. Then think about what happens if the room is not well mixed. 


**Thoughts?**

* Age 
* Sex
* Room size
* Ventillation & Airflow/draft
* Distancing of desks
* Location in the Country
* Arrangement of desks
* 
* PPE
* Anything else?


How does infection rate depend on class size?

 * exponentially

* size of the room
* number of students infected



How does it depend on $N$?


Proportional to $N$, or $e^N$ or somethng else?


Well mixed crowd it is more like to be $N^2$

Class of 40 or two classes of 20?
