Most relevant text on the current situation of Covid-19 pandemic, is a chapter on Spreading Phenomena from Alberto Barabasi’s book - Network Science. This chapter discusses epidemic modeling, contact networks, social distancing, flattening the curve, prediction models, etc.
We had read this book long back, but who would have thought this would make sense in the current outbreak!
Here is the link of the chapter: http://networksciencebook.com/chapter/10
Highly recommended to read!
