About the Course

The COVID-19 crisis has created an unprecedented need for contact tracing across the country, requiring thousands of people to learn key skills quickly. The job qualifications for contact tracing positions differ throughout the country and the world, with some new positions open to individuals with a high school diploma or equivalent. In this introductory course, students will learn about the science of SARS-CoV-2 , including the infectious period, the clinical presentation of COVID-19, and the evidence for how SARS-CoV-2 is transmitted from person-to-person and why contact tracing can be such an effective public health intervention. Students will learn about how contact tracing is done, including how to build rapport with cases, identify their contacts, and support both cases and their contacts to stop transmission in their communities. The course will also cover several important ethical considerations around contact tracing, isolation, and quarantine. Finally, the course will identify some of the most common barriers to contact tracing efforts -- along with strategies to overcome them....

I don't have access to the final Assessment any longer but I do have have an issue with one of the questions you may want to review. The question is about how the virus is transmitted with select all the answers that apply. I believe it is the 2nd or 3rd option about transmission via droplets on the bottom of a shoe. I was not sure about selecting it or not but we did learn that transmission can occur when someone touches a surface then touches their mouth, nose or eyes which is possible if one touches the bottom of their shoe. Also, in the news media it has been suggested people should take their shoes off when they enter their homes as one way of bringing the virus into their homes. Also, I recall there is an extra word in the sentence which can be misleading. In the end I decided it was a possible source of transmission, although low risk, even though the question didn't indicate that the person touched their mouth, nose or eyes so selected the answer but turned out it was not correct. Not a big issue for me but thought you might want to reconsider that answer as an option for future test takers. Hope this is helpful!

An excellent course, which should be taken by *every* person in the United States, regardless of your interest in contact tracing; this is the information the general public needs to know and understand the reasons for isolation and quarantine of those testing positive for COVID-19, those who have extended contact, and the rationale for postponing large public gatherings.

I learned so much about COVID 19 and what everyone's concerns are in keeping safe. This course will give me the ability to help many people understand how they protect those they come in contact with.

the narrator was very articulate and covered a great deal of information and variables. Helped me to greatly understand importance of contacting and tracing in order to minimize the impact on others

Quick and easy to understand, but the section of the course that showed the young minority man conducting a case interview incorrectly every time and the young white female conducting the case interview correctly every time definitely seemed to imply some bias. It's best to either switch up actors or at least switch up results so that each actor is not predominantly right or wrong. It distracted from the course and after 2-3 examples started to make me not want to listen or pay attention.

This course provided very clear, important information that, while I may not choose to become a contact tracer, I will be able to use to help me and my family during this pandemic.

A good introduction to the phone skills needed. Some more emphasis on why verifying the case/contact's dob and address is so important and how to handle if the person says they can't talk right now could be good. Knowledge of basic psychology of grief: denial, anger, bargaining, depression and acceptance, and how it relates to a + diagnosis/isolation may be helpful too.

I enjoyed the course for the most part. HOWEVER I admit I was highly distracted by the "narrator" (instructor?). She sounded like a 90's "Valley Girl"....I kept waiting for her to add comments such as "Oh My God, Like Totally!".... She did NOT sound professional. (just my 2 cents)

Very accommodating course, as someone who has worked in public health, this course pretty much sums up all the need-to-know information about COVID-19 and covers a lot of useful tips and tricks for doing contact tracing.

Excellent, as well as timely. Information presented could not be complete, of course, given how many unknowns there are about the virus and our governments' responses and the myriad variables with likely cases and their contacts. But the information was clearly presented and user friendly. Since it comes from Johns Hopkins, there's a sense of authority and expertise behind it – helpful in these times of spurious theories coming from all quarters.

Now. Sign me up, and let's kick this virus to the curb!

Excellent course. The instructor Dr. Gurley spoke so clearly and the concepts were explained in such an easy way to understand. The slides were very good and easy to follow as well.

Thank you!

The course is excellent BUT the task at hand really needs to be done by a social worker, physician's assistant, or someone with a medical background. This is no time for amateurs like me to walk the fine line between collecting data and giving advice that may or may not be applicable in the situation at hand. There needs to be a standardized script all Tracers use to be consistent and objective without attempting to be intrusive. Also, with the political divide in this country, Tracers are subject to abuse, violating constitutional rights and putting themselves positions of being sued. This job is for professionals and not rank-and-file.

This Contract Tracing Course offered Free by the John Hopkins Bloomberg School of Pub Health clarified many pertinent questions regarding the important facts that must be considered while we in the World are facing a Pandemic. It was free of political bias, opinion, and assured the just and nonjudgmental care to all beings.
