Что (кто) такое INFECTIOUSNESS - определение

PATHOGEN'S ABILITY TO INFECT HOSTS
Infectiousness

Infectiousness         
·noun The quality of being infectious.
Infectivity         
In epidemiology, infectivity is the ability of a pathogen to establish an infection. More specifically, infectivity is a pathogen's capacity for horizontal transmission — that is, how frequently it spreads among hosts that are not in a parent–child relationship.
Infectious period         
  • latent period]], the infectious period (the period of communicability) and the [[incubation period]]. In some diseases, as depicted in this diagram, the latent period is shorter than the incubation period. A person can transmit an infection without showing any signs of the disease. Such an infection is called a [[subclinical infection]].
TIME INTERVAL DURING WHICH A HOST (INDIVIDUAL OR PATIENT) IS INFECTIOUS, I.E. CAPABLE OF DIRECTLY OR INDIRECTLY TRANSMITTING PATHOGENS TO ANOTHER SUSCEPTIBLE HOST
Infective period; Period of communicability; Period of infectiousness; Communicability period; Contagious period; Period of contagiousness; Transmission period; Transmissibility period
In epidemiology, particularly in the discussion of infectious disease dynamics (mathematical modeling of disease spread), the infectious period is the time interval during which a host (individual or patient) is infectious, i.e.

Infectivity

In epidemiology, infectivity is the ability of a pathogen to establish an infection. More specifically, infectivity is a pathogen's capacity for horizontal transmission — that is, how frequently it spreads among hosts that are not in a parent–child relationship. The measure of infectivity in a population is called incidence.

Infectivity has been shown to positively correlate with virulence, in plants. This means that as a pathogen's ability to infect a greater number of hosts increases, so does the level of harm it brings to the host.

A pathogen's infectivity is subtly but importantly different from its transmissibility, which refers to a pathogen's capacity to pass from one organism to another.
