prevalencerefers to the number of cases of disease thatexistsin a population and the incidence refers to the number of new cases of diseaseoccurringin a population.
The noun 'incidence' has many synonyms. A few of them are: frequency, percentage, prevalence, proportion, tendency, commonness, trend and extent. The meaning of incidence is the rate or frequency of which something occurs.
Relative risk (RR) can be calculated by comparing the incidence rates of an event occurring in two groups. First, determine the incidence rate in the exposed group (e.g., those with a risk factor) and the incidence rate in the unexposed group (e.g., those without the risk factor). Then, divide the incidence rate of the exposed group by the incidence rate of the unexposed group (RR = Incidence Rate in Exposed / Incidence Rate in Unexposed). A RR greater than 1 indicates increased risk, while a RR less than 1 indicates decreased risk.
Incidence rates vary between 25 and 50 per 100,000 persons.
Incidence refers to the number of new cases of a disease in a specific population over a defined period, while prevalence indicates the total number of existing cases at a particular time. Public health officials use these metrics to assess the severity and spread of a disease; a rising incidence may signal an outbreak or increased transmission risk, while high prevalence can indicate a chronic health issue. Together, they help prioritize resources and interventions, guiding responses based on the urgency and impact of the disease within the community.

The incidence will equal the prevalence when the duration of the disease is equal to the time period over which the incidence is measured.
P/1-P where 1-P is the prevalence odds. This is true for prevalence values that are bigger. Prevalence=Incidence rate x Duration (true for small prevalences)

The noun 'incidence' has many synonyms. A few of them are: frequency, percentage, prevalence, proportion, tendency, commonness, trend and extent. The meaning of incidence is the rate or frequency of which something occurs.
Incidence rate measures the number of new cases of a disease that occur in a specific population during a defined time period, reflecting the risk of developing the disease. In contrast, prevalence rate indicates the total number of existing cases (both new and pre-existing) of a disease in a population at a particular point in time, providing insight into the overall burden of the disease. While incidence focuses on new occurrences, prevalence encompasses all cases, highlighting the disease's impact on a population.
The incidence rate for cerebral palsy in the UK is rare. According to the statistics there is a mean annual prevalence of 2 per every 1000 live births.
Incidence rate and prevalence are crucial for understanding morbidity because they provide insights into the frequency and distribution of diseases within a population. Incidence rate indicates how many new cases occur in a specific timeframe, helping to assess the risk of developing a condition. Prevalence reflects the total number of existing cases at a given time, which aids in understanding the overall burden of disease on healthcare systems. Together, these measures inform public health strategies, resource allocation, and interventions aimed at reducing morbidity.
Incidence is number of new cases diagnosed prevalence is the the burden of disease that is new cases plus old cases

I really don't know...I can't find anything in the net regarding this and I really need the prevalence now for my case presentation.....hmpfff....
