From Gostic et al. (2020):

The effective reproductive number, denoted as or \(R_e\) or \(R_t\), is the expected number of new infections caused by an infectious individual in a population where some individuals may no longer be susceptible

Also called the instantaneous reproductive number.

Generation interval

The time between the infection date of an individual and the infection date of the person who infected them. This is typically described by a statistical distribution, such as a gamma, lognormal or weibull.

Serial interval

The time between the symptom onset date of an individual and the symptom onset date of the person who infected them. This is typically described by a statistical distribution, such as a gamma, lognormal or weibull.
