When reporting prevalence in a formal paper, researchers typically either use a percentage or a number divided by 10,000 or 100,000. For example, suppose the prevalence of disease X is calculated as .024. When reporting this value, researchers will write something like: 1. The prevalence of disease X is 2.4%. 2. Disease X is prevalent in 240 out of...

For example, suppose researchers take a random sample of 5,000 individuals in a certain city and find that 90 people have developed disease X in the past year while an additional 30 h...

In science, prevalence describes a proportion (typically expressed as a percentage). For example, the prevalence of obesity among American adults in 2001 was estimated by the U. S. Centers for Disease Control (CDC) at approximately 20.9%.
May 22, 2023 · Prevalence is a measure of how common a disease process is found in a specified at-risk population at a specific time point or during a specified time period. Prevalence is thus a measure of disease burden for the specified population, or how commonly someone with the disease will be encountered in the specified population.
