Two health professionals sitting side-by-side.

Antibiotic resistance on a global scale is no longer a possibility—it is a startling reality, reports the World Health Organization (WHO). In 2014, the United Nations agency published findings from its comprehensive study of microbial resistance data from 114 countries.* The Centers for Disease Control reports that at least 2 million people become infected with antibiotic-resistant bacteria annually. Of those infected, at least 23,000 people die from infections that no longer respond to antibiotics.

Antibiotics Overprescribed for People and Food Animals

Antibiotic resistance comes from the overuse and misuse of antibiotics in healthcare settings and in factory farms that raise animals for human consumption. Doctors routinely prescribe antibiotics for viral infections, even though viruses don’t respond to antibiotics. Food animals are routinely given antibiotics to promote faster growth and prevent them from getting sick. Every time we eat or touch meats, we risk being contaminated with antibiotic-resistant bacteria. And so it goes. These persistent practices are creating serious public health and food safety problems internationally.

Increased Demand for Public Health Professionals

In our complex, interconnected world, the public health profession is booming. According to the Bureau of Labor Statistics, as of 2012, 23% of America’s workforce became eligible for retirement. Job shortages are happening now or are projected to happen in vital public health positions—from public health doctors and nurses to healthcare educators, administrators, and epidemiologists.

Due to the wide range of job positions in the public health profession, job market growth varies widely. The biggest changes in projected job growth for public health professionals (2012–2022) is 23% for medical and health services managers and 21% for health educators and community health workers. At the lower end of the spectrum, projected job growth for epidemiologists is 10% which is 1% lower than the average 11% job growth for all occupations projected for 2012–2022 by the Bureau of Labor Statistics.

Public health professionals are in the trenches locally, nationally, and internationally as educators, managers, researchers, analysts, advocates, policymakers, and caregivers. Their relentless frontline efforts help inform and protect communities, minimizing the repercussions of public health concerns.
