aR0: The average number of secondary cases caused by an infected individual during the outbreak; here, R0 is reported either for a specific outbreak, when available, or as a measure calculated based on multiple past outbreaks. bSSE: Superspreading events—number of infections caused by a single individual during an outbreak; number of infections caused by multiple superspreading events during the same outbreak are separated by commas.
