One Health


Berry College is the first college in the country to develop a One Health program specifically for undergraduate students. The centerpiece of the program is the One Health minor.

One Health, sometimes called One Medicine, is the concept that the health of any population, human or otherwise, is dependent upon other animal species with which it interacts as well as the environment in which these interactions occur. For example, understanding the factors contributing to the seasonal transmission of influenza from migrating waterfowl to humans would be a One Health approach to a worldwide problem.

One Health encourages transdisciplinary collaborations between physicians, veterinarians, epidemiologists, public health administrators, ecologists, climatologists, economists, medical researchers, as well as numerous other specialties, as dictated by the specific problem. By understanding the contributions of each discipline and the techniques they bring to bear on such problems, the student of One Health gains a unique understanding of population health and its relationship to the environment, as well as how to assemble an effective One Health team.

Students graduating with a One Health minor will enjoy a significant advantage when applying to medical, veterinary and graduate school programs. Anyone interested in pursuing a career in a health care or environmental-related field will benefit by understanding the concepts embedded within the One Health approach.

Berry College is especially well suited to be the first undergraduate institution in the country to offer a minor in One Health. The Berry College science faculty is well versed in One Health, with strong backgrounds in ecology, infectious disease and population health. The Berry College campus, the largest in the world, offers a truly unique outdoor laboratory, providing innumerable opportunities for relevant research projects. Berry College faculty and students routinely collaborate with the Centers for Disease Control (CDC) and regional major research universities, which brings a depth of expertise and opportunity unique to a school this size.

Why should a student consider a One Health minor?
One reason is that someone graduating with this minor will have a firm foundation in cutting edge public health theory. In addition, the student gains practical “real world” experience through faculty-mentored research projects. The One Health approach is now part of many veterinary, medical and graduate-level public health programs. Those undergraduate students with the foundation this minor provides will be well ahead of their peers upon applying and entering these programs.

The One Health curriculum: The One Health minor curriculum was developed with a focus on providing a well-rounded foundation to the One Health concept.
The minor has three principal functions.

  •  To instill in students the interdisciplinary approach inherent to the One Health concept.
  •   To provide students a broad foundation upon which they can make informed decisions about career choices, as well as potential avenues to achieve their personal goals.
  •  To provide students with practical and meaningful research experiences.

The One Health minor curriculum core requires 9 credit hours unique to the minor (OHS designated courses). The student must complete three specifically tailored One Health Sciences (OHS) courses, as well as additional elective courses from a select list. The OHS courses are intended to provide the student with a conceptual framework for what One Health is, details into the techniques and methods used in investigations and research, and finally development and execution of their own research project. An additional one credit hour seminar course will serve both as a capstone course and as venue for students to present the results of their research project.
The remaining balance of the 18+ credit hours must be chosen by the student from a designated list of elective courses. This allows the student to focus upon a particular area of interest while still establishing a firm foundation in One Health. Similarly, by working with specific faculty, the research element of the program can be tailored to suit the student’s needs and interests. 

Required Courses

Course                                          (Credit hours)

OHS 200   Concepts in One Health          (3)
OHS 300   Case Studies in One Health    (3)
OHS 490   OHS Seminar                          (1)

One of Three OHS Focused Topic Courses Below:

OHS 480    Advanced Topics in One Health    (2 - 6 hours)
OHS 496    Academic Internship       (2 - 6 hours)
OHS 498    Directed Studies             (2 - 6 hours)

A student cannot use both OHS496 and OHS498 to satisfy the 18+ hours required for the One Health minor. 

Pending approval by the One Health committee, hours from OHS480 can be applied to the elective requirement once either OHS 496 or 498 has been completed.

Elective Courses

Sufficient credit hours must be chosen from biology, animal science, chemistry, environmental science, math and geology courses to complete the 18+ hour requirement. Elective credit must include at least one course from a discipline outside the student’s major. The student is reminded that prerequisites or consent of instructor may be required for these courses. Any course, whether in residence or as transient, deemed to be of appropriate scope and content by the One Health committee, may be substituted as a One Health elective requirement if approval is obtained prior to taking the course.
