The spread of COVID-19

I read an online paper today which explained that the rate of spread of this Coronavirus depends of two factors:

1) The density of the population.

2) The density of the population.

I heard it was three factors, the density of the population being the third.

Like compressed ham or half chewed fish. I'll stay condensed in my flat & look out the window. Very funny - 'thumbs' for that...
