What exactly is public health? While doctors diagnose and treat patients individually, public health professionals do so on a grander scale. For example, a doctor may work with a patient to minimize the physical effects of a sexually transmitted disease (STD). A public health professional specializing in epidemiology might coordinate with community leaders to stop the spread of that very same STD. According to the Center for Disease Control (CDC), the nation’s premier public health agency, the philosophy is simple: find out what’s making people sick and killing them, and then do the things that work to protect them and make them healthier.

During the 20th century, the average lifespan worldwide increased by 30 years. Twenty-five of the years can be attributed directly to advances in public health. These advances fall into three main categories: health, disease and safety.

Safer and Healthier Foods: Contaminated food, milk and water cause many infections, including typhoid fever, tuberculosis, botulism and scarlet fever. Initiatives to ensure safer and healthier foods have resulted in significant decreases in microbial contamination. The discovery of essential nutrients and their roles in disease prevention has been instrumental in reducing nutritional deficiency diseases such as goiter, rickets and pellagra in the United States.

Family Planning: Family planning health includes smaller family size and longer interval between the birth of children; increased opportunities for pre-pregnancy counseling and screening; fewer infant, child and maternal deaths; and the use of barrier contraceptives to prevent pregnancy and transmission of human immunodeficiency virus and other STDs.

Healthier Mothers and Babies: From 1915 through1997, the maternal mortality rate declined to less than 0.1 reported deaths per 1,000 live births, and the infant mortality rate fell to 7.2 per 1,000 live births. Environmental interventions, improvements in nutrition, advances in clinical medicine, increased access to health care, better disease surveillance and monitoring, and higher standards of living contributed to these remarkable declines.

Tobacco as a Health Hazard: Smoking is the leading cause of preventable disease in the U.S. Recognition of tobacco use as a health hazard has resulted in restrictions on cigarette advertising, consumer education campaigns and initiatives aimed at reducing the population’s exposure to environmental tobacco smoke.


The overall impact of public health professionals on global health and wellness is clear. Yet those in the field who make the difference do so in many different ways. Public health careers come in myriad shapes in sizes, from policy and legislation to research and community outreach. Some of public health’s most notable careers include the following:

  • Legislative Policy Advisor +

    Those interested in improving public health may desire to get more involved on the legislative front by becoming a legislative policy advisor. These individuals conduct extensive research in key areas in an effort to either support or combat legislation that pertains to health and wellness.

    In most instances, a bachelor’s degree is required to obtain a position as a legislative policy advisor. Public health advisors strongly influence politicians and members of Congress, helping to determine whether a bill passes or fails. Policy advisors earned an estimated $40,000 mean salary in 2012.

Public health professionals protect the health of local, national and international communities. From promoting seatbelt use to monitoring pandemics, they impact our daily lives in both large and small ways. The federal government’s Healthy People 2020 initiative calls for an increased number of trained public health professionals to meet current and future demand. Opportunities in the field continue to expand, as do options for earning credentials online.

Students can earn an online public health degree from either a traditional college or one that is fully online. There are also options to enroll in blended programs where some of the coursework is completed online and some in a classroom. Certain programs allow students to combine the coursework of a bachelor’s and a master’s, enabling them to earn both degrees in less time.

Advantages of earning a public health degree online include:


Online learning can be done whenever it fits the student’s schedule. This is particularly beneficial for those who wish to work while in school.


Students have options for earning their degree on a full- or part-time basis. Programs can be tailored to best fit the student’s timetable.


Many online students report forging strong connections with their professors and peers.

Cost Savings

While tuition is usually the same for online programs as for classroom-based ones, students can save money on expenses related to commuting, childcare and even room and board.

Online Public Health Degree Success

Students who are successful in the pursuit of an online public health degree often share certain characteristics. Like classroom learners, online students need to have self-discipline, good time management skills and stay on top of their schoolwork. Being comfortable with technology is also a requirement. Students need to be at ease communicating and interacting with other people without face-to-face contact.

Online Public Health Degree Accreditation

Whether online or classroom-based, the public health degree program you choose must be accredited. An accredited college or degree program has been assessed by an independent agency and found to meet certain quality standards. The college accreditation process ensures your education investment is protected. It weeds out fly-by-night schools and diploma mills focused on making a profit rather than on education. Accredited colleges will not accept credits from non-accredited institutions, an important consideration for those considering a master’s or who want to transfer to another school. And, very importantly, only accredited colleges and universities qualify for federal financial aid funds.

Traditional colleges that offer online degree programs usually receive accreditation from one of six regional accrediting agencies. Online schools may earn further accreditation via the Distance Education and Training Council (DETC). In addition, schools have the option of seeking accreditation for their public health programs from The Council on Education for Public Health (CEPH). Before enrolling at a college or majoring in public health, make sure each educational option you vet carries the proper credentials.


Are online public health degree programs accepted by employers?

Most definitely. Even top universities today offer online degree programs where students earn the exact same diploma as those learning on campus. It’s often impossible for employers to tell how a degree was earned. As long as the online degree program has the proper accreditation, employers will accept the degree.

What types of public health degrees are available online?

Online public health degrees are available at every level – associate, bachelor’s, master’s and doctoral. Online certificates in specific public health areas are also offered.

Is an online public health degree easier to complete than a classroom-based program?

No. Online degree programs carry the same accreditation as in-person programs. Some online courses can even more rigorous than their classroom-based counterparts due to the time management and self-discipline involved.

Are there opportunities to earn practical experience or study abroad through an online public health degree program?

Whether online or classroom-based, most public health degree programs require some sort of practical experience. Because the field has such global implications, study abroad experiences are also encouraged. Online public health degree programs work with students on an individual basis to ensure they gain field experience through internships, study abroad opportunities, or service learning projects.

Are scholarships available to students pursuing online public health degrees?

Students pursuing online public health degrees are eligible for the same local and national scholarships as those students pursuing classroom-based degrees. In addition, most schools offer their online students scholarships based on merit or financial need.
