I misread the title. I was really hoping this was a link to house-rules on playing the Pandemic cooperative boardgame with the COVID-19 coronavirus as the disease.
Using a mix of Legacy and Expansion Pack rules: Sharpie the name COVID-19 onto the game board for your least favorite color. Every outbreak of that color is now doubled (as if it had been drawn twice from your deck). It's up to your group if you want that to also effect overall difficulty (if those double outbreaks count as double towards the game's lose condition counter).
