Epidemology

• incidence: occurrence of new cases of disease, injury, or other medical conditions over a specified time period
• prevalence: the proportion of a population with a disease or a particular condition at a specific point in time
• mortality rate: number of deaths per unit of population during a given time interval
• mortality: occurrence of death
• morbidity: the state of having a disease or a medical condition
• •epidemiology uses a systematic approach to:

  •1 count the number of cases of disease

  •2 calculate the rate of disease

  •3 compare rates, either over time or between different groups.
• How does epidemiology try and prevent disease? And what is the acronoym?

  •Identify cause

  •Determine extent in population

  •Identify trends

  •Study progression and rates

  •Plan and evaluate preventative and therapeutic measures

  •Develop public policy

  CATS PLAY TOGETHER, RABBITS PAINT PICTURES
• In an epidemiological study, once you have collected data about the incidence and prevalence of a disease, what would be the next steps?

  •Identify trends and patterns and how the disease spreads. This can help with identifying the cause of the disease and how it can be prevented.
• Why is public health policy so important?

  Because it can help prevent the incidence of disease which will decrease the overall prevalence, rather than just treating it when it occurs
• What are the 3 classification systems in epidemology?

  •Communication

  •Policy

  •Education programs
• Communication helps prevent spread of diseases by raising awareness
• Policies help prevent the spread of diseases by allowing for a systemic change for peoples behaviours
• Education programmes help prevemt the spread of diseases by improving knowledge
