Answers

A1. Preventing exposure to the pathogen

The use of vaccines, along with public health measures like quarantine and hygiene, has been pivotal in controlling outbreaks, such as the global eradication of smallpox by 1980 through extensive vaccination campaigns.

A2. No

Case reports are detailed descriptions of individual cases and are primarily used to identify new or rare conditions, rather than to establish causal relationships or generalize findings across populations.

A3. Stratified sampling ensures that subgroups are represented proportionally in the sample

Stratified sampling was first formalized in statistical theory in the early 20th century to improve the accuracy of surveys by accounting for population diversity. It is especially useful in political polling or market research where certain subgroups, such as age or income levels, must be adequately represented.
