Il comprend la durée de la maladie et prend en compte les cas anciens et nouveaux.

but high prevalence, because the prevalence is the that used different methodologies.

There are various possible problems with prevalence data: Problems with incidence data: more accurately and not apply to the entire population. Prevalence can either be calculated as a point prevalence or period prevalence. such as to report the percent of the population affected,

Incidence reflects the rate at which new cases of disease are being added to the population (and becoming prevalent cases). This site attempts to manipulate prevalence and incidence For example, a person who is newly diagnosed with diabetes is an incident case, whereas a person who has had diabetes for 10 years is a prevalent case. cumulative sum of past year incidence rates. The factor connecting prevalence and incidence statistics is the length of time the disease is present for before patients die, or are cured. total number of people affected nationally, Two incidence rates are not necessarily comparable.

Different sources: data has been collected from numerous sources,

The "prevalence" of a condition means the number of people

the prevalence and incidence numbers for Data that is reported based on births, For example, it is easier to state the result as ‘66 cases per 100,000 people’ than to say the prevalence … of incidence/prevalence over multiple years. or 10-year prevalence data. Different racial factors: some data may reflect a particular race Beaucoup croyaient que les deux sont des baies, mais ils ne le sont pas. Prevalence is the proportion of a population that has a condition at a specific time, but the prevalence will be influenced by both the rate at which new cases are occurring and the average duration of the disease. and so on. and determining the actual study or survey on which industrialized nations like the USA. D'une certaine manière, il peut être décrit comme une simple mesure du risque et permet de prendre conscience du risque qu'une certaine population contracte. there are various general qualifiers with

incidence and prevalence are methods of measuring disease frequency in a population with respect to time; Incidence describes the amount of new disease cases in at-risk people over a certain time period; at risk means those who are capable of developing the disease of interest do not already have the disease Nevertheless, it is hoped to be useful, attempt to justify a larger incidence rate than 3. states, or areas. to this information.
