Aggressiveness can be quantified by several parameters, including the basic reproduction number (R0), the incubation period, and the case fatality rate (CFR).
- R0: This is the average number of secondary infections produced by a single infected individual in a fully susceptible population. A higher R0 indicates more aggressive spread. - Incubation Period: Shorter incubation periods mean faster symptom onset and quicker spread. - Case Fatality Rate: The proportion of deaths among diagnosed cases; a higher CFR can signal more severe disease.
