At a Glance
Online epidemiology degrees range from associate-level stepping stones to doctoral programs. Most epidemiologist positions require at least a master’s degree. Most professionals enter the field through a Master of Public Health (MPH) or a Master of Science (MS) in epidemiology from a CEPH-accredited program.
Epidemiologists track disease outbreaks, identify risk factors, and design interventions that protect population health. According to the Bureau of Labor Statistics, employment in the field is projected to grow 16 percent from 2024 to 2034, much faster than average, with a median annual wage of $83,980. If you’re considering this path, the degree decisions you make early on shape everything that follows. This guide covers what each level of online study looks like, what to expect from the curriculum, and how to choose the right program for where you want to go.
Online Epidemiology Degrees by Level
Online epidemiology programs aren’t built the same way across degree levels. At the undergraduate level, you won’t find a standalone epidemiology major at most schools, because the field requires graduate training before most employers will hire into it. What you will find are related degree options that serve as strong preparation for a master’s program. If you’re also exploring campus and hybrid formats, our overview of epidemiology degree programs covers the full range of delivery options. At the graduate level, the distinction between degree types matters more than most guides explain.
Starting with an Associate Degree
An associate degree won’t lead directly to epidemiology work, but it can be a practical first step toward a bachelor’s program in a relevant field. The most useful associate-level programs give students grounding in health sciences, data, or the biological sciences, all subjects that carry forward into undergraduate and eventually graduate study.
A few online associate degrees that align well with this path:
- Health science: Covers public health foundations, health economics, and social determinants of disease, all concepts that show up in graduate epidemiology programs.
- Medical billing and coding: Builds fluency with health records, data systems, and the informatics infrastructure that epidemiologists depend on for surveillance work.
- Statistics: Data analysis is central to epidemiology. An associate-level statistics program builds the quantitative foundation that graduate programs expect.
- Nursing: Clinical exposure, patient interaction, and a working knowledge of anatomy and physiology give nursing students a practical backdrop for population health study.
- Respiratory therapy: Useful for students drawn to infectious disease or environmental epidemiology, as conditions affecting breathing are a recurring focus of outbreak investigation.
Online Bachelor’s Degrees in Epidemiology-Related Fields
A bachelor’s degree is required for admission to most epidemiology master’s programs. Standalone undergraduate epidemiology majors are less common than public health or biological science degrees, so most students pursue a related degree that demonstrates the quantitative and scientific preparation graduate programs look for. Public health programs with a quantitative focus tend to be the most direct route.
- Public health: An undergraduate degree in public health, especially one that includes coursework in biostatistics and epidemiology methods, is the most common path into a graduate epidemiology program. Look for programs that offer courses in statistics, research methods, and health policy alongside the core public health curriculum.
- Biostatistics: Data analysis, statistical methods, and computing are skills epidemiologists use daily. A biostatistics degree is strong preparation, and some graduate programs combine the two fields into a joint track.
- Environmental science: Students interested in environmental epidemiology, studying how pollution, water quality, and climate affect health outcomes, will find this degree directly relevant. Coursework in ecology, atmospheric science, and human health provides a useful context.
- Sociology: Social epidemiology, which examines how factors like income, race, and housing shape disease patterns, draws heavily on sociological theory and research methods. A sociology background pairs well with this concentration.
- Nutrition: Students interested in nutritional epidemiology or food safety research will find that undergraduate training in dietetics, chemistry, and public health aligns closely with graduate program expectations.
The Online Master’s Degree in Epidemiology
The master’s degree is where most epidemiology careers begin. Most entry-level positions at state health departments, the CDC, hospitals, and research institutions require at least a master’s degree. Two degree types dominate the field, and understanding the difference helps you choose the right program for your goals.
MPH vs. MS: Which Degree Is Right for You?
The Master of Public Health (MPH) with an epidemiology concentration is practice-oriented. It’s designed for professionals who want to work in public health agencies, community health organizations, or government settings. The curriculum covers epidemiologic methods alongside broader public health competencies in health policy, program planning, and social determinants of health.
The Master of Science (MS) in epidemiology is research-intensive. It’s the better fit for students heading toward doctoral study, academic research, or analytical roles in pharmaceutical or biostatistics-heavy environments. Coursework focuses more narrowly on study design, statistical modeling, and epidemiologic theory, with a greater emphasis on producing independent research.
Neither is objectively better. The right choice depends on whether you want to apply epidemiology in practice or advance it through research.
Accreditation: Why CEPH Matters
For MPH programs specifically, CEPH accreditation is widely recognized and valued by public health employers. Federal agencies, state health departments, and major health systems are familiar with the credential when reviewing applicants. An MS degree doesn’t follow the same accreditation framework, but the institution’s regional accreditation and the program’s research reputation carry equivalent weight for research and doctoral-track positions.
Before enrolling in any program, verify its accreditation status directly on the CEPH website.
Admissions Requirements
Most master’s programs in epidemiology expect a bachelor’s degree in a relevant field, a minimum GPA (often 3.0 or above), letters of recommendation, and a personal statement. Some programs require GRE scores, though many have dropped this requirement in recent years. Programs with a biostatistics component may evaluate your quantitative coursework specifically, so undergraduate statistics or calculus can strengthen an application.
Many online master’s programs also require or recommend some professional experience in public health or a related field, particularly for MPH programs designed for working professionals.

Online Doctorate Degrees in Epidemiology
A doctorate is the appropriate path for those pursuing academic research, senior positions at federal agencies, or leadership in epidemiologic science. Online doctoral programs in epidemiology typically require three to five years of study and often expect applicants to hold a master’s degree, though some programs admit exceptional candidates directly from a bachelor’s program. Doctoral work culminates in a dissertation based on original research, and students can specialize in areas such as cancer epidemiology, infectious disease, environmental health, or genetic epidemiology.
Doctoral programs expect applicants to arrive with strong methodological and statistical foundations, usually from a completed master’s degree, and often require students to identify a faculty advisor whose research interests align with their own before admission is granted.
Example Doctoral Curriculum
Core courses at the doctoral level build on master’s-level methods with greater depth and a stronger emphasis on independent research production.
| Core Course |
Description |
| Analysis of Health-Related Data |
Advanced data collection methods, analysis strategies, reporting frameworks, data cleanup, file management, and manuscript preparation. |
| Advanced Methodology |
In-depth coverage of advanced data analysis methods, including design and conduct of population-based research. |
| Application of Biostatistics |
Statistical concepts and lesser-known methodologies: descriptive biostatistics, probability distributions, interval estimation, and hypothesis testing. |
| Advanced Epidemiologic Study Designs |
Detailed application of case-control studies, cohort studies, and clinical trials, the three major frameworks of epidemiologic research. |
| Ethics and Conduct of Research |
Ethical frameworks for public health research, conflict of interest, animal research protocols, reporting misconduct, and applicable law. |
Some programs require or recommend internships and fellowship placements alongside doctoral coursework. These experiences accelerate professional network development and give students exposure to real-world research environments before graduation.
