- What is major difference between an endemic disease and an epidemic?arrow_forwardIf a disease X has a duration of 15 years and a low incidence (5 per 100,000 person-years). If another disease Y has a duration of 5 years and a low and low incidence (5 per 100,000 person years). If we compare disease X and Disease Y in the same population, we would expect: a) Better cure b) lower prevalence c) higher prevalence d) Higher incidence e) shorter durationarrow_forwardDifferentiate among the patterns of disease outbreaks accordingto frequency, number, and location.arrow_forward

Researchers are studying HIV prevalence using a cross-sectional study design. Which of the following factors may affect the researchers' assessment of HIV prevalence in their study population? Choose all that apply and explain your answer. a) Changes in HIV treatment b) Changes in HIV virulence (HIV virulence refers to the ability of the virus to cause disease) c) Population changes (e.g. migration) due to HIV infection, for example people who leave their community to live closer to physicians specialized in treating HIV d) Other factors which may affect survival of HIV-infected persons (e.g. changes in healthcare practices) e) Changes in HIV diagnostics f) Changes in HIV awareness and educationarrow_forward
- Explain the differences between incidence rates and prevalence rates.arrow_forward1. The leading cause of death worldwide is 2000 is due to 1) none 2) congenital disease 3) lifestyle risk factors 4) communicable disease 2. To differentiate incidence from prevalence: 1) whether the event is a new case ; time of onset of the disease 2) presence or absence of a disease ; time period is arbitrary ; rather a snapshot in time 3) number of new cases of disease during a specified period od time/population at risk 4) useful in the study of burden of chronic diseases and implications for health servicesarrow_forwardIdentify the following scenarios as either endemic, epidemic, or pandemic disease or classify descriptions as either primary, secondary, or tertiary prevention.
