Which of the following is a main goal of public health?

The main goal of public health is to prevent epidemics and the spread of disease. Public health focuses on the health of populations through monitoring health trends, implementing health promotion strategies, and ensuring that communities are protected from health threats. This includes surveillance of diseases, vaccination campaigns, and the establishment of health policies that mitigate risks and reduce the incidence of infectious diseases.

Preventing epidemics is critical not just for individual health, but for the health of entire communities and populations. Effective public health strategies aim to identify potential outbreaks early, contain them, and educate the public on practices that minimize transmission. Through these efforts, public health initiatives work to improve health outcomes and enhance the quality of life for all individuals.

The other options do not align with the core objectives of public health. Encouraging individual wealth may contribute to overall well-being, but it is not a primary goal of public health initiatives. Reducing competition among healthcare providers is more related to economic and business strategies rather than public health goals. Promoting international tourism, while beneficial for economies, does not directly address health outcomes or prevent disease.
