Exponential Growth

What makes COVID-19 different from other coronaviruses is how contagious it is; it spreads exponentially, which means that as the number of people infected increases, so does the rate at which the infection spreads to more people.

R0 (pronounced R-nought) is a term used to quantify how contagious a disease is. The R0 of COVID-19 is presently 2-2.5 %, which means each infected person is expected to spread the virus to two others on average, thus putting into motion the chain of progression.

However, on a slightly brighter side, this also means that the inevitable decline of COVID-19 will be exponential as well.
