R0: The maths behind the Basic Reproduction Number

Показать описание
Explains the important concept of Basic Reproduction Number (R0, R-nought), provides mathematical justification for the definition of R0 as the Dominant Eigenvalue of the Next Generation Matrix, and shows how it generalises across a range of different disease transmission structures. Also provides examples of the Next Generation Matrix, and the associated R0 (dominant eigenvalue) for Vector-Host disease (malaria), SIR model, and multi-group SEIR model.

Appreciate the lengthier video on this one.

Loving the jokes thrown here and there. 24:40 Using linear algebra is so simple as to 'kill' the fun. No pun intended..

Very nice video, thank you! My solution for the exercise at the end is K = beta * S0 / gamma + beta * epsilon * S0 / nu

can you make a video about calculating R0 of SEIQRS model ? I'm stuck :(

Hi! Thanks for this nice video. You mentioned in the intro that you will cover network type models. Do you have any plans for it (soon)? Could you share links to some material which calculates R_0 for network based models? Thank you very much in advance.
