Thoroughly enjoyed the content I was learning, excited to use my beginner level skills with GIS where I can, and continue my education in the healthcare field. Thank you for providing this opportunity to spark an interest in a field I had no knowledge of before. While this course barley scratched the surface of Epidemiology, I feel miles ahead in terms of my intellect than before starting this course.

Great introduction to the study of epidemiology. Very helpful understanding the origins of epidemiology how it has evolved into public health practice today. The course provided good information of the various tools that cabe be used to convey public health data to decision makers as well as the public. Looking forward to taking the next course in the specialization!

This course Is a great Introduction Into using the tools for Epidemiology In Public Health Practice. I strongly recommend It for those who need to update their skills or who are getting started In the field. Only one suggestion: update the GIS section as so many of the data sources have changed. Other than that, great class.

The course has inspired me to search out other opportunities to learn how to map more data. I audited the course and think I'll come back to submit the quizzes and assignments. The directions to the GIS exercise have been updated and, though I struggled through, I felt accomplished with my map at the end of the course!

I really learn and enjoy the course, I will take the next 4 courses. I would like you to answer our doubts, in this course, to me, it was so difficult to use the software QGIS, because when I applied the symbology the map "relatively disappeared" (!!), I did it around 8 times.

Thank you very much :-)

This course had a easy to compreend language, dinamic and interactive. I loved to see simulations of real situations on the tests questions because it seems the knowlegde I had adquire can be easly used in real life. Also, it was important have a shown exemple while I was trying to do my own graphs.

This was a great course, comprehensive at an introductory level, and extremely well-taught. The only improvement I can suggest is that the visual material, graphs, charts, etc., be in a form that can be copied or downloaded. I found that the screen shots I took were generally too small to read.

This was a great refresher course for Epidemiology. I appreciate the timing as it relates to the COVID-19 outbreak. This course allowed me to pull together public health ideas and facts that will give me the opportunity to help find trends of the spread of COVID-19 in my community.

Thank You.

Great content and great instructor - I found it very appropriate for my level (beginner) but it still allowed me to challenge myself during the exercises. Would recommend to anyone considering public health in their future career plans as a way to get started in learning about the field.

This course was incredibly informative and interesting, and it made me appreciate the work that public health researchers and professionals do. While I had only a vague idea of what public health was before, I can now confidently explain the type of role it plays in our day-to-day lives.

I gained so much knowledge about epidemiology. Especially with the coronavirus making its way around the world, it is good to know how data is captured as far as statistics and knowing the numbers, we can see how fast viruses spread. This was a great course!

I believe this course's strongest attribute of this course is the lessons from week 4 that focus on QGIS mapping tools. I learned quite a bit about the tool and feel much more comfortable using the tool. I would recommend this as an introductory course.
