About the Course

This course aims to provide managers and developers of contact tracing programs guidance on the most important indicators of performance of a contact tracing program, and a tool that can be used to project the likely impact of improvements in specific indicators. Students who complete the course will be proficient in using the Contact Tracing Evaluation and Strategic Support Application (ConTESSA) to estimate the impact of their contact tracing program on transmission and strategizing about how to increase their program’s impact. A secondary audience for the course will be decision makers interested in knowing more about the characteristics of effective contact tracing programs, and strategies to improve. The course is designed for individuals who are already leading contact tracing programs who have significant experience with epidemiology and public health. We strongly recommend completing this course on a laptop or a desktop rather than a phone as you’ll need to complete worksheets and open the course and the application simultaneously....

This course is an advanced level course on COVID-19. I love this course so much. From this course we know about the use of programmed apps for contact tracing. It is very helpful for job aspirants.

Excellent albeit difficult ( at least for me). The instructors and material provided is just great. Everybody who wants to support their community should do the course and get the qualification.

I don’t understand why my score was NOT recorded. This class did nit seem as seamless as the Cintract Tracer Course.

This class not not offer a quiz before the 9-question ending.

The information was totally helpful, but for me, the testing process was not good. — especially based on the intensity of the material.

it was a cofusing for me and should not have required the amount of math it did (for those of us who are not math fans).

i was appreciative of the interactive app and its calculator.

i was confused with the worksheet insturctions to perform the calculations for the purposes for this speciific 3rd quiz as opposed to future calculations.

i do appreciate the opporunity to retake the quiz.

This course was the second Covid 19 related course I took through Coursera, and provided by JHU. It was one with some challenging and analytic exercises but you will be happy once you go through them. It would be helpful If you study what the meaning of the medical terms first tomake it easier for you to do the exercises on Contact Tracing.

This course increased my understanding of statistics and analysis in public health. This topic was touched on briefly in my Public Health Curriculum. I am glad I did this course. I feel a little more prepared but still need a lot more practice with this theory in order to make an impact in the real world. Thank you. I learned a lot.

This course is a nice complement to the preceding COVID-19 Contact Tracing course also offered by the same institution. While that course is aimed to on-the-ground contact tracers, I think this course will be interesting to central community/agency planners and epidemiologists to make sense of the data from the contact tracing efforts.

The course was useful in exploring the ways that various factors can have an impact on the transmission of the COVID-19 virus. The lectures were presented very well, with appropriate amounts of knowledge that is easily understood without being boring or overwhelming the less studious. Thank you very much for this course.

This was a very tough course but so worth it. As a nurse working with COVID-19 patients, this was great information for me to learn how to trace contacts, collect data, and how to input the data into a computer program. This will assist me on the job with providing care to my patients.

I learned a lot from this course. Very difficult quiz and tricky questions. But if you read, focus on the questions, and put the right data, you will be able to get the right answers. To all the professors and facilitators, very well done.
