Intervention mapping [1] is a protocol for developing theory-based and evidence-based health promotion programs. Intervention Mapping describes the process of health promotion program planning in six steps: the needs assessment based on the PRECEDE-PROCEED model
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 ...
Graph of herd immunity threshold vs basic reproduction number with selected diseases. S will be (1 − q), since q is the proportion of the population that is immune and q + S must equal one (since in this simplified model, everyone is either susceptible or immune). Then:
The intervention mapping approach of Bartholomew et al. [11] makes an extensive use of the logic model through the whole life-cycle of a health promotion program. Since this method can start from as far as a vague desired outcome (author's example is a city whose actors decide to address "health issues" of the city), planners go through various ...
Clinical health promotion emanates from the health care system where the patient is the active/activated part and hence the efforts also include elements of health promotion and rehabilitation.Emphasis is placed on keeping choice and accountability with the patient, as well as empathy, feedback and positive expectations for the patient.
For the full specification of the model, the arrows should be labeled with the transition rates between compartments. Between S and I, the transition rate is assumed to be (/) / = /, where is the total population, is the average number of contacts per person per time, multiplied by the probability of disease transmission in a contact between a susceptible and an infectious subject, and / is ...
Common issues that are the subject of public health interventions include obesity, [3] drug, tobacco, and alcohol use, [4] and the spread of infectious disease, e.g. HIV. [5] A policy may meet the criteria of a public health intervention if it prevents disease on both the individual and community level and has a positive impact on public health ...
