Question

Major public health achievements of the twentieth century include:

A) Discovery of antibiotics
B) Introduction of electronic cigarettes
C) Development of nuclear weapons
D) Implementation of childhood vaccination programs

Answer 1

The major public health achievements of the twentieth century are the discovery of antibiotics like penicillin and the implementation of childhood vaccination programs, which have significantly reduced infectious diseases and improved life expectancy.

Step-by-step explanation:

Among the major public health achievements of the twentieth century, two stand out based on their significant impact:

The discovery of antibiotics, such as penicillin in 1941, which led to the development of a series of other antibiotic drugs that have controlled infectious diseases effectively.

The implementation of childhood vaccination programs, with scientists developing immunizations for diphtheria, cholera, pertussis, tuberculosis, tetanus, and yellow fever between 1890 and 1930, dramatically reducing childhood mortality and morbidity.

On the other hand, the introduction of electronic cigarettes and the development of nuclear weapons are not considered public health achievements, as they do not contribute to the improvement of public health. In fact, nuclear weapons pose significant risks, and the health impacts of electronic cigarettes are still being assessed.
