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.

Even though I wasn't able to join the frontliner force in fighting this virus during this pandemic, I was able to navigate and understand the context of how difficult it is to contact trace those who were affected by the virus. Thank you so much to Johns Hopkins Bloomberg School of Public Health for this great online course. God bless.

This course is very comprehensive and perfectly balanced between theory and practice. It will be very useful as a innovated tool for the monitoring and implementing of actions aimed to control SARS-CoV-2 pandemic in my country. Thanks for the opportunity.

This is a very interesting course for learning how to measure the COVID-19 infection rate and make use of the ConTESSA: Interactive Tool to Estimate Impact of Contact Tracing. This course also teaches how to read and create graphs with the COVID-19 data.

This training was accelerated and challenging but extremely informative. The hands on training for using the ConTESSA App, metrics worksheets and comparison scenarios was very impressive and has definitely increased my knowledge base.

Solid information. My contessa app bugged out because I had it open for multiple days but it worked well to compute the averages and impact information. Great course for anyone really! I am a computer guy and got into the info.

this course is great just don't have outside distraction when trying to complete it you have to have focus to get it right. Because of the nature of the tool you don't want to make any or should I say to many errors .

This course gave me a deeper understanding on Contact Tracing and its impact. The use of Contessa application, has given me wider view of how to make analysis and could help in recommending strategies.

Dear whom this concerns:

Thank you for allowing me to join in once again for the managerial contact tracing course. However, as I reviewed the curriculm, I found that the course wasn't right for me.

It looked tough. I would suggest that you assign more exercises that are easy before getting to the more complexed ones.

The second module was reviewed too fast by the instructor and therefore made the second quiz needlessly difficult ...
