Epidemics begin in one of three model independent ways.
- Exponential
- Power
- Linear
COVID-19 grew exponentially in New York City and Mississippi until Stay-in-Place orders were declared - despite the vast differences in population density.
NYC has tamed an exponential epidemic, first by slowing the new infections to a merely linear daily increase then ultimately lowering the new cases to ever smaller numbers.
Mississippi also entered a prolonged linear phase - averaging 266 new cases a day - but after three months the numbers of new cases (and with a delay, deaths) are again accelerating.
Explore the striking similarities and important differences between NYC and Mississippi data in the COVID-19 menu to the right.
