More specifically, infectivity is the extent to which the pathogen can enter, survive, and multiply in a host. It is measured by the ratio of the number of people who become infected to the total number exposed to the pathogen. [1] Infectivity has been shown to positively correlate with virulence, in plants. This means that as a pathogen's ...
Pathogenicity is the potential disease-causing capacity of pathogens, involving a combination of infectivity (pathogen's ability to infect hosts) and virulence (severity of host disease). Koch's postulates are used to establish causal relationships between microbial pathogens and diseases.
An infection is the invasion of tissues by pathogens, their multiplication, and the reaction of host tissues to the infectious agent and the toxins they produce. [1] An infectious disease, also known as a transmissible disease or communicable disease, is an illness resulting from an infection.
The terms "intrinsic incubation period" and "extrinsic incubation period" are used in vector-borne diseases.The intrinsic incubation period is the time taken by an organism to complete its development in the definitive host.

In microbiology, the multiplicity of infection or MOI is the ratio of agents (e.g. phage or more generally virus, bacteria) to infection targets (e.g. cell).For example, when referring to a group of cells inoculated with virus particles, the MOI is the ratio of the number of virus particles to the number of target cells present in a defined space.

Rotaviruses elicit both B and T cell immune responses. Antibodies to the rotavirus VP4 and VP7 proteins neutralise viral infectivity in vitro and in vivo. [87] Specific antibodies of the classes IgM, IgA and IgG are produced, which have been shown to protect against rotavirus infection by the passive transfer of the antibodies in other animals ...
