What is the difference between incubation period and communicable period?
The period between exposure and infection is called ‘latent period’, since the pathogen is present in a ‘latent’ stage, without clinical symptoms or signes of infection in the host.
The period between exposure and onset of clinical symptoms is called ‘incubation period’..
What is infectious 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. capable of directly or indirectly transmitting pathogenic infectious agents or pathogens to …
What is considered communicable disease?
What is a communicable disease? A communicable disease is one that is spread from one person to another through a variety of ways that include: contact with blood and bodily fluids; breathing in an airborne virus; or by being bitten by an insect.
What are the 4 stages of communicable illness?
The natural history of an untreated communicable disease has four stages: stage of exposure, stage of infection, stage of infectious disease, and stage of outcome.
What are the 5 stages of disease?
The five periods of disease (sometimes referred to as stages or phases) include the incubation, prodromal, illness, decline, and convalescence periods (Figure 2). The incubation period occurs in an acute disease after the initial entry of the pathogen into the host (patient).
What stage of infection is most communicable?
In some cases, a person is contagious during the incubation period, while in others the person is not contagious until the illness begins. The amount of time a child remains contagious depends on the infection and the child. Young children are often contagious for longer than older children.
