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.
Immunizations: Since 1900, smallpox was eradicated through vaccinations. Vaccines have been developed or licensed against 21 other diseases, including polio and measles, dramatically reducing the incidence of infections and deaths.
Declines in Death from Heart Disease and Stroke: Heart disease and strokes together account for approximately 40 percent of all deaths in the United States. Since 1950, age-adjusted death rates from cardiovascular disease (CVD) have declined 60 percent, representing one of the most important public health achievements of the 20th century.
Control of Infectious Diseases: Public health action to control infectious diseases in the 20th century were based on the 19th century discovery of microorganisms as the cause of many serious diseases, such as cholera and tuberculosis. Improvements in sanitation and hygiene, the discovery of antibiotics, and the implementation of universal childhood vaccination programs, all contributed to infectious disease control.
Fluoridation of Drinking Water: Fluoridation of community drinking water is a major factor responsible for the decline in tooth decay during the second half of the 20th century. The history of water fluoridation is a classic example of clinical observation leading to epidemiologic investigation and community-based public health intervention.
Motor Vehicle Safety: Motor vehicle safety initiatives focus on protecting occupants and educating drivers and pedestrians. Seat belts, child safety seats, public awareness about the dangers of drinking and driving and stricter laws and law enforcement are all results of public health efforts.
While many of these important initiatives are ongoing, the 21st century brings with it new public health challenges. Predominant among these are “diseases of comfort,” such as those caused by obesity and physical inactivity, a major focus of public health today. Many experts agree that major advances in public health improvement over the next decades will come not from new medical findings or cures, but from the development and application of population-based prevention programs.
Workplace Safety: Public health efforts have led to physical changes in the workplace, such as improved ventilation and dust suppression in mines; safer equipment; development and introduction of safer work practices; and improved training of health and safety professionals and of workers.
Earn a Degree
The need for public health professionals at the national, state and local levels continues to rise. For
example, U.S. Bureau of Labor Statistics predicts a 21% increase in community health workers between 2012 and
2022. Also, in its Healthy 2020 initiative, the federal government called for an increase in public health
experts across the country to prevent and treat diseases, identify potential threats, and facilitate
collaboration both within and across communities. This demand, however, requires a larger and more flexible
supply of higher educational opportunities in the field, both on campus and online. Access to quality degree
programs in public health and related majors remains a critical step toward healthier communities and a
Online Public Health Degrees
Many students may ask how an online degree in public health works. How can something that requires hands-on
training and patient interaction work via online learning? Colleges and universities across the U.S. address
these challenges in two specific ways. (1) Hybrid learning.
Part of the degree program takes place online, including written coursework such as exams and exercises, as
well as routine collaboration with professors and peers. In contrast, students must visit either a campus or
another medical center or laboratory with which the school has a partnership. (2) Targeted programs.
It’s true that many public health programs call for in-person work, yet some don’t. For example, an
established professional looking to add management experience can take online MPH courses from home.
CEPH Accredited - MPH curriculum covers Epidemiology, Biostatistics, Health system administration and management, Environmental health sciences & Behavioral and social sciences. Request Information Here!
CACREP - CSWE Accredited Learn more about online Bachelor and Master's degrees in Public Health, Human Services, Social Work, Counseling, Addiction and more. Request Information Here!
When considering an online degree in public health, it’s important to assess why the online learning mode
could be the better option. Key benefits of online learning in public health 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 to earn a degree on a full or part-time basis. Programs can be tailored to best fit the student’s timetable.
Social Distance Learning
If a student feels comfort in a learning environment without being surrounded by classmates; online learning options are a great solution.
Many online students report forging strong connections with their professors and peers.
Online programs are accessible to anyone, anywhere. Students have all kinds of different professional backgrounds. This diversity can expose online students to unique and eyeopening perspectives, creating a richer educational experience.
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.
Accredited Public Health Schools: With distance separating U.S. residents students are either close or far to campus learning. In the last twenty years the growth of online degree programs have fixed this issue. With advanced technology virtual classrooms have become more of the new norm than the distant past. Furthermore, with technology at our fingertips online college degrees in public health are available with CPHE accreditation. You can live in one region of the country and attend a school in a different region, from the comfort of home, a coffee shop, local library, or any location that may suffice. It is recommended to always the opportunity to know your online degree options.
Traditional colleges that offer online degree programs usually receive accreditation from one of six regional accrediting agencies listed by (CHEA). Online schools may earn further accreditation via the Distance Education Accrediting Commission (DEAC). 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 and accreditation.
