Study Notes
Introduction to Epidemiology
- Host individual susceptibility influenced by age, gender, marital status, and nutritional status, but not family size.
- A disease is classified as endemic when it has a constant presence within a specific population.
- Constant presence of a disease within a geographic area is termed "endemic."
- Hygiene conditions are not classified as host factors; they include age, gender, family background, and nutrition.
- Reporting 100 cases of cholera in Jeddah would be recognized as an outbreak.
- Necessary factors are crucial for disease occurrence; without them, consequences cannot arise.
- An epidemic that spreads globally is termed a pandemic.
- Diseases that occur irregularly, at unpredictable times, are classified as sporadic.
- Descriptive epidemiology encompasses place, person, and time but does not include association.
- British epidemiologist John Snow is noted for his investigation into cholera’s distribution.
- An outbreak is defined as two or more linked cases in the same time and place.
- Age, sex, and marital status are host factors; hygiene conditions are excluded.
- A scenario involving a 68-year-old falling in a bathroom is inconclusive regarding cause.
- Cholera is identified as a water-hygienic disease, while hepatitis could fall under this category.
- Shallow wells are more prone to transmitting water-borne diseases.
- The increase in respiratory infections during winter represents a seasonal trend.
- Clinicians are encouraged to consult patients early in outbreak investigations to formulate hypotheses about causes.
- Cholera is a notable example of a water-borne disease.
- Epidemiology focuses on studying the distribution and determinants of health-related states.
Morbidity
- A report on cardiovascular diseases in a 40 million population in 2012 noted 30,000 confirmed cases of CHF at the year's start.
- There were an additional 12,000 new CHF diagnoses throughout 2012.
- By year-end 2012, there were 23,000 total deaths registered, with congestive heart failure as the underlying cause for 4,000 of those deaths.
- The incidence rate of CHF during 2012 was calculated at 30 per 100,000 persons.
