Public Health Career Paths


Description: Epidemiologists study the causes of diseases in populations, how diseases spread, and what risk factors are associated with those diseases. Most of their work involves numbers and statistics and have the responsibility of overseeing what information should be gathered and how that data should be analyzed. Sometimes they help explain study results to stakeholders, policymakers, and the public. Epidemiologists can also work towards preventing diseases from occurring. They can study multiple types of diseases (STDs, chronic diseases, infectious diseases, etc.) or they can specialize in a field or in a specific topic (Tuberculosis, MERS, Norovirus, etc.). This work if often solitary and involves a lot of computer time, such as monitoring surveillance systems for outbreaks.

Qualifications: Most Epidemiologists have at least a master’s degree, typically in Public Health with a specific focus in Epidemiology. For upper-level positions, a doctorate degree is required. Some Epidemiologists also have a background in medicine or nursing. Those pursuing this career need to be able to work both individually and collaboratively and have a strong background in math and statistics. Prior working with statistical programs is a plus since learning how to use them is hallmark to this career.

Salary: Nationwide, the average pay for epidemiologists is $61,000 per year, and ranged between $40,000 and $113,000 per year. Those in senior level positions can make up to $122,000 per year, depending on location and industry. Epidemiologists who hold doctorate degrees usually start with higher salaries than those with a master’s degree.

Infection Preventionist

Practices for Infection Preventionists can include surveillance of infectious diseases, investigation of cases and outbreaks, training of staff members, development and enforcement of infection control policies, and evaluation of the effectiveness of infection control efforts. Infection preventionists help track down the source of outbreaks when they occur and help control the issue. They spend some of their time collecting and analyzing data, but also supervising other staff members practices, participating in patient rounds, attending meetings, and designing and leading interventions to improve infection control. Some Infection Preventionists work with larger communities to provide guidance on controlling epidemics, protecting against emerging diseases, or planning in case of a bioterrorism attack.

Qualifications: Requirements for this career path depend on what industry the career is in. It is recommended that individuals who pursue this career have an understanding of Epidemiology and data analysis techniques, in addition to having a strong background in science to understand how diseases are transmitted.

There are also infectious disease physicians and PhDs whose work focuses on infection control.

Salary: Salaries vary depending on specific qualifications, responsibilities, and employment location. The average salary is roughly $80,000 per year, especially for those with a doctorate degree. Those who have a nursing degree typically have a salary between $50,000 and $75,000 per year.
