Epidemiology and Disease Causation Quiz

Primary prevention aims to prevent disease occurrence, whereas antibiotics are typically used for treatment.

Direct contact involves physical touch or proximity between infected and susceptible individuals.

Vector-borne diseases are transmitted to humans via arthropods like mosquitoes.

Experimental studies involve intervention, while epidemiological studies observe disease patterns.

Genetics can influence health outcomes, but it's not modifiable like other determinants.

R₀ indicates the potential of disease spread within a population.

Cohort studies track the development of a disease in a specific group to identify risk factors.

Case-fatality rate measures the severity of a disease by indicating the likelihood of death.

Randomization helps in distributing confounding variables evenly among treatment groups.

Incubation period signifies the time taken for symptoms to appear after exposure to a pathogen.

Herd immunity reduces disease transmission by protecting susceptible individuals.

Zoonotic diseases are transmitted from animals to humans, like rabies from infected animals.

Prevalence indicates existing cases, while incidence tracks new cases over a set time frame.

Confounding variables can distort the association between exposure and outcome in epidemiological studies.

Sensitivity analysis assesses the robustness of study findings by testing variations in key parameters.
