What term describes the ability of an organism to enter, survive, and multiply within a host, with or without clinical signs?

Explanation:
Infectivity is the capacity of a pathogen to enter, survive, and multiply within a host and establish infection, regardless of whether it causes any symptoms. This means exposure can lead to infection even if the individual remains asymptomatic. This concept is distinct from pathogenicity, which is about whether an infection leads to disease; virulence refers to the severity of disease once it occurs; and immunogenicity concerns the ability of the pathogen to provoke an immune response. For example, a microbe with high infectivity might commonly establish infections, yet many of those infections could be asymptomatic, illustrating the separation between infection and disease.
