What is public health?
What is public health and why should you apply for a public health program?
Public health—it maybe a topic that you’ve heard a lot about lately. But what exactly is it?
Public health is the science of protecting the safety and improving the health of communities by
- promoting healthy lifestyles;
- researching and understanding disease and injury prevention;
- implementing educational programs;
- recommending policies;
- administering services;
- promote health equity, quality, and accessibility; and
- detecting, preventing, and responding to infectious diseases.
While doctors and nurses are primarily focused on treating individuals after they become ill, public health practitioners are concerned with protecting the health of entire populations. These populations could be as small as one neighborhood or city, or as substantial as an entire country.
What Do Public Health Practitioners Do?
Public health practitioners identify the health problems and needs of a community, and then implement programs and services to address those needs.
Master of Public Health (MPH) graduates are often employed within the government’s public health system, but may also find success in the non-government sector. Like many other health professions, the exact position in which a public health practitioner finds employment is dependent on the skills and experience acquired prior to the degree, the area of specialized focus of the program, and the needs of the employing organization.

They’re all united by one common goal though: improving their communities by promoting and protecting the population’s health.
