  • Course Learning Objectives

    Upon successfully completing this course, students will be able to:

    • Describe and discuss the main epidemiological characteristics of the major infectious diseases of humans
    • Describe how these epidemiological characteristics can be utilized to develop and evaluate strategies to prevent epidemic or endemic transmission of the major infections of humans
    • Identify and examine epidemiological characteristics such as incubation period, infectious period, means of transmission
  • Course topics

    Concepts and methods in infectious disease epidemiology:  Overview of microbiology, molecular epidemiology, models of infectious disease dynamics, study design 

    Prevention/Control of infectious diseases: Nutrition and infectious disease, vaccines,control of hospital acquired infections, disease eradication strategies

    Respiratory infections: Tuberculosis, influenza, pneumococcus, measles 

    Vector borne infections: Viral infections of the central nervous system, malaria, lyme disease 

    Sexually transmitted infections: HIV, gonorreah, syphillis, HPV

    Diarrhoeal disease

    Hepatitis viruses (A, B, C, E)

  • Course Description

    Introduces the basic methods for infectious disease epidemiology and case studies of important disease syndromes and entities. Methods include definitions and nomenclature, outbreak investigations, disease surveillance, case-control studies, cohort studies, laboratory diagnosis, molecular epidemiology, dynamics of transmission, and assessment of vaccine field effectiveness. Case-studies focus on acute respiratory infections, diarrheal diseases, hepatitis, HIV, tuberculosis, sexually transmitted diseases, malaria, and other vector-borne diseases.

  • Course Schedule

    Please see the course Session for a full list of dates and items for this course.

  • Intended Audience

    Masters and doctoral students in Epidemiology, MMI, and International Health

  • Methods of Assessment

    Student grades in the course will be based upon:


    1. 10% Student presentations

    During the last half of each class, a small group of students will present and lead a discussion on one article from the literature list posted on CoursePlus. The presentation should be no more than 10 slides, approximately 20 minutes in duration, and address the following points:

    1.   What was the motivation for performing this study/context?

     2.    What was the study hypothesis?

     3.    BRIEFLY describe the epidemiology of the pathogen under study such as transmission mechanisms, the population-at-risk, or risk factors for infection. How can the epidemiological characteristics can be used to prevent transmission of the pathogen.

     4.    Describe the main method used to complete the study objective such as study design, study population, methods of case/disease detection, or laboratory methods.

     5.   What were the main results of the study?

     6.   What were the primary conclusions of the study authors? Were they justified?

     7.   What are the implications for public health practice? How can you apply the results and/or findings from this article for public health perspective?

    2. 10% Quizzes

    Every weeks, 3-6 multiple choice questions related to recent lectures will be posted on CoursePlus. The quizzes will be open-book and should be completed by each student individually.

    Quizzes are pass/fail, where a score of 50% or more is required for passing. 


    3. 30% Midterm exam

    The midterm exam will consist of 10-15 short answer questions on CoursePlus. The exam will be open-book and should be completed by each student individually.


    4. 50% Final exam

    The final exam will consist of 25-30 multiple choice questions. The exam will be an in-class, closed-book, cumulative assessment of the material presented throughout the course. 


    Exam Make-up Policy: Students are informed of exam dates on the first day of class. Students with a legitimate conflict (e.g., clinical responsibilities, research presentations, jury duty, or personal travel with scheduled itineraries that pre-date the start of the class) must inform the course instructors. The course instructors will inform students with such conflicts of their options for making up the exam. Unexpected personal or family emergencies during the course will be handled on a case-by-case basis. Students who experience such unforeseen events should contact the course instructors as soon as possible to arrange for completing missed work or exams.

  • Required Text(s)

    Reading assignments will be posted in the online library at the beginning of second term.  Course readings are required.  

    Text Book (Required)

    Infectious Disease Epidemiology: Theory & Practice (3rd Edition), edited by Kenrad E. Nelson, Carolyn Masters Williams, and Neal M.H. Graham. Copies are on reserve at Lillienfield Library (Hampton House). .

    Research Articles (Required)

    Topic--specific research articles are assigned for each lecture. Research articles will be posted on the course website (online library).
