Time Lapse Map of Covid-19’s Spread Across the US, 2/2020 to 9/2021

Using data from Johns Hopkins, this time lapse video shows the spread of Covid-19 across the US from Feb 2020 to Sept 2021. This looks so much like small fires exploding into raging infernos and then dying down before flaring up all over again. Indeed, forest fire metaphors seem to be particularly useful in describing pandemics like this.

Think of COVID-19 as a fire burning in a forest. All of us are trees. The R0 is the wind speed. The higher it is, the faster the fire tears through the forest. But just like a forest fire, COVID-19 needs fuel to keep going. We’re the fuel.

In other forest fire metaphorical scenarios, people are ‘kindling’, ‘sparks being thrown off’ (when infecting others) and ‘fuel’ (when becoming infected). In these cases, fire metaphors convey the dangers posed by people being in close proximity to one another, but without directly attributing blame: people are described as inanimate entities (trees, kindling, fuel) that are consumed by the fire they contribute to spread.
