Study Notes
Disease Classification
- A disease occurring at a stable rate in a specific area is known as endemic.
- Expected prevalence is determined by the anticipated occurrence of a disease based on historical data.
Modes of Disease Transmission
- Indirect infectious disease transmission can happen through vehicles.
- Noncommunicable diseases do not spread between individuals; an example is Giardiasis.
- Endogenous transmission sources include pathogenic organisms like Candida albicans.
Epidemiology Responsibilities
- Epidemiologists focus on controlling disease vectors, quarantining infectious patients, and providing public education.
- The development of antibiotics is not a direct responsibility of epidemiologists.
Disease Phases
- The common cold is classified as an endemic disease.
- Symptoms first appear during the prodromal phase.
- The period when an infectious agent's replication is controlled and symptoms begin to resolve is called the period of decline.
Outbreak Terminology
- A widespread disease within a region during a specific time frame is termed an epidemic.
- If an epidemic extends globally, it is labeled a pandemic.
- The reservoir is where a pathogen naturally resides, either in animate or inanimate forms.
Transmission Types
- Vertical transmission occurs when pathogens transfer from mother to offspring, classified as direct contact transmission.
- Transmitting illness through contaminated food is categorized as vehicle transmission.
Public Health Facts
- True: Bacteria are the most common causes of healthcare-associated infections (HAIs).
- Common HAIs include pathogens like Staphylococcus aureus and Clostridium difficile.
- Prevalence refers to the total number of individuals afflicted with an infectious disease within a population.
Epidemiological Strategies
- Common strategies to break the epidemiological triangle include public education, quarantine, and vector control.
- Alternative prevention methods are not considered a standard strategy in epidemiology.
