The following outline is provided as an overview of and topical guide to concepts related to infectious diseases in humans.. Infection – transmission, entry/invasion after evading/overcoming defense, establishment, and replication of disease-causing microscopic organisms (pathogens) inside a host organism, and the reaction of host tissues to them and to the toxins they produce.
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 ...
Nursing theory is defined as "a creative and conscientious structuring of ideas that project a tentative, purposeful, and systematic view of phenomena". [1] Through systematic inquiry, whether in nursing research or practice, nurses are able to develop knowledge relevant to improving the care of patients.
The following areas are assessed through questions asked by the nurse and medical examinations to provide an overview of the individual's health status and health practices that are used to reach the current level of health or wellness. [1] [2] Health Perception and Management; Nutritional metabolic
Modern population-based health management is complex, requiring a multiple set of skills (medical, political, technological, mathematical, etc.) of which epidemiological practice and analysis is a core component, that is unified with management science to provide efficient and effective health care and health guidance to a population.
An infectious disease agent can be transmitted in two ways: as horizontal disease agent transmission from one individual to another in the same generation (peers in the same age group) [3] by either direct contact (licking, touching, biting), or indirect contact through air – cough or sneeze (vectors or fomites that allow the transmission of the agent causing the disease without physical ...
The relationship between the 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.
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.
