28 Jun, 2023
If you're considering a career that makes a meaningful impact on communities, understanding the various public health areas is one of the smartest first steps you can take. I've spent years helping healthcare professionals find their ideal roles through healthcareers.app, and I can tell you that the breadth of opportunity in public health is staggering — from epidemiology and environmental health to the hands-on diagnostic roles that keep our healthcare system running smoothly. Whether you're drawn to population-level health initiatives or prefer the precision of clinical diagnostics, there's a public health career path that fits your skills, interests, and ambitions.
In this comprehensive guide, I'll walk you through the major public health areas, spotlight high-demand roles like cardiovascular technicians and ultrasound techs, and give you actionable advice on how to launch or advance your career in this essential sector.
Public health is an expansive field dedicated to protecting and improving the health of entire populations. Unlike clinical medicine, which focuses on treating individuals, public health takes a broader view — examining patterns, preventing disease, and promoting wellness across communities. According to the Centers for Disease Control and Prevention (CDC), public health efforts have added 25 years to the average American lifespan over the past century. That's the power of this work.
Here are the core public health areas that drive this impact:
Epidemiologists are the detectives of public health. They investigate disease outbreaks, study patterns of illness and injury, and develop strategies to prevent future health crises. The COVID-19 pandemic put this discipline in the spotlight, but epidemiologists have been quietly saving lives for decades. If you love data, research, and problem-solving, this is a deeply rewarding field.
Closely related to epidemiology, biostatistics applies statistical methods to biological and health-related problems. Biostatisticians design studies, analyze clinical trial data, and help public health agencies make evidence-based decisions. It's a field where your math skills directly translate into better health outcomes for millions of people.
Environmental health professionals study how our surroundings affect our well-being. This includes everything from air and water quality to chemical exposure and climate change. According to the National Institutes of Health (NIH), environmental factors contribute to an estimated 70% of all cancers, making this one of the most critical public health areas for long-term population health.
This area focuses on designing, implementing, and evaluating health policies and programs. Professionals in this space work in government agencies, nonprofit organizations, hospitals, and consulting firms. If you're interested in the intersection of healthcare and leadership, health policy and management offers a clear path to executive-level roles.
Understanding why people make the health decisions they do — and how to encourage healthier behaviors — is at the heart of community and behavioral health. Professionals in this area design public health campaigns, run community outreach programs, and work to reduce health disparities among underserved populations.
Global health professionals tackle health challenges that cross national borders. From infectious disease prevention to maternal and child health initiatives in developing countries, this area attracts individuals who want to make a worldwide difference. Organizations like the World Health Organization and Doctors Without Borders are major employers in this space.
While not always categorized under traditional public health, diagnostic healthcare roles are essential to the public health infrastructure. Cardiovascular technicians, ultrasound techs, laboratory scientists, and radiologic technologists provide the diagnostic data that informs public health decisions, clinical treatments, and disease surveillance. I consider these roles the backbone of effective healthcare delivery, and they deserve a closer look.
One of the most rewarding careers at the intersection of clinical care and public health is the cardiovascular technician. I frequently see job seekers on healthcareers.app searching for this role, and for good reason — it combines hands-on patient care with cutting-edge technology.
The cardiovascular technician job description encompasses a range of responsibilities centered on diagnosing and treating heart and blood vessel conditions. Here's what a typical day might look like:
Most cardiovascular technician positions require at least an associate degree in cardiovascular technology or a related field. Many employers prefer candidates who hold certification from Cardiovascular Credentialing International (CCI) or the American Registry of Diagnostic Medical Sonographers (ARDMS). I always recommend pursuing certification early in your career — it significantly increases your competitiveness and earning potential.
According to the Bureau of Labor Statistics (BLS), cardiovascular technologists and technicians earn a median annual salary of approximately $62,740. The BLS also projects employment in this field to grow by about 5% through 2032, which is on pace with the average for all occupations. However, I've observed that demand can be significantly higher in metropolitan areas and regions with aging populations, where cardiovascular disease prevalence is greatest.
Another diagnostic role that consistently ranks among the most popular searches on our platform is the ultrasound tech — formally known as a diagnostic medical sonographer. This career offers excellent job security, competitive pay, and the satisfaction of playing a critical role in patient care.
An ultrasound tech uses specialized equipment to create images of the body's internal structures using high-frequency sound waves. These images help physicians diagnose conditions ranging from pregnancy complications to tumors, blood clots, and organ dysfunction. Key responsibilities include:
Most ultrasound tech positions require an associate or bachelor's degree in diagnostic medical sonography. Certification through ARDMS is widely considered the gold standard in the field. Many ultrasound techs pursue additional specialty certifications to increase their versatility and earning power — for instance, adding vascular sonography credentials alongside abdominal sonography.
The Bureau of Labor Statistics reports that diagnostic medical sonographers earn a median annual salary of approximately $84,990, making this one of the higher-paying allied health professions. Even more impressive, the BLS projects a 7% growth rate for this occupation through 2032, driven by an aging population and the increasing use of ultrasound as a preferred imaging modality due to its non-invasive nature and lack of radiation exposure.
I think it's important to highlight the connection between broad public health areas and specific diagnostic roles like cardiovascular technicians and ultrasound techs. Here's why these connections matter for your career planning:
Disease surveillance and prevention: Cardiovascular disease remains the leading cause of death in the United States, according to the CDC. Cardiovascular technicians and ultrasound techs are on the front lines of early detection, which is a core public health objective.
Health equity: Expanding access to diagnostic imaging in underserved communities is a major public health priority. Professionals willing to work in rural or community health settings are in especially high demand.
Data-driven decision making: The diagnostic data produced by cardiovascular technicians and ultrasound techs feeds directly into public health databases and research, informing everything from treatment guidelines to health policy.
Preventive care models: As healthcare shifts toward prevention-focused models, the demand for skilled diagnostic professionals continues to rise. Understanding where your role fits within the broader public health landscape can help you position yourself for long-term career success.
With so many public health areas to choose from, narrowing down your options can feel overwhelming. Here's the framework I recommend to job seekers on healthcareers.app:
Among traditional public health disciplines, health policy and management, biostatistics, and epidemiology tend to offer the highest salaries, particularly at the master's and doctoral levels. In diagnostic healthcare, ultrasound techs earn a median salary of approximately $84,990 per year, making it one of the most lucrative allied health careers available with an associate or bachelor's degree, according to the Bureau of Labor Statistics.
The cardiovascular technician job description involves performing diagnostic tests such as EKGs, echocardiograms, and stress tests; assisting with invasive cardiac procedures like catheterizations; monitoring patient vital signs; maintaining equipment; educating patients about their procedures; and documenting results accurately. It's a dynamic role that blends technical skill with patient care.
Becoming an ultrasound tech typically requires completing an accredited associate degree program (about two years) or a bachelor's degree program (four years) in diagnostic medical sonography. After completing your education, you'll want to earn certification through ARDMS, which most employers require or strongly prefer. Some programs also offer one-year certificate options for individuals who already hold a degree in a related health science field.
Absolutely. Many cardiovascular technicians and ultrasound techs leverage their clinical experience to move into public health education, health policy, research coordination, or healthcare administration. Pursuing a master's in public health (MPH) while working is a common and highly effective strategy. Your clinical background gives you a practical perspective that's incredibly valuable in public health leadership roles.
Yes. The COVID-19 pandemic dramatically increased awareness of and investment in public health infrastructure worldwide. According to the Bureau of Labor Statistics, employment in community and social service occupations — which includes many public health roles — is projected to grow faster than the average for all occupations through 2032. Diagnostic roles like cardiovascular technician and ultrasound tech also continue to see strong, steady demand.
The diversity of public health areas means there's truly something for everyone in this field — whether you're passionate about community health education, excited by the analytical rigor of epidemiology, or drawn to the hands-on precision of roles like cardiovascular technician or ultrasound tech. What unites all these paths is a shared mission: improving health outcomes for individuals and communities alike.
