St. Charles County Public Health: What is contact tracing and why is it important?

File photo

Contact tracing is the process of identifying people who may have been exposed to a contagious disease like COVID-19 and investigating those people, and those who they may have contacted, to stop the spread of that illness.

Contact tracers work with individuals to make a list of people with whom they may have interacted while they were potentially contagious.

Contact tracers then contact the people on the list, provide them guidance on next steps and begin asking questions. They may ask where a person works, where they have visited, where they obtained food or other supplies, and with whom they may have met. If that person has interacted with others, the process starts again.

Those being investigated play a key role in the effort to prevent further spread of illness. Those that are exposed will be asked to self-quarantine themselves and to monitor the progression of symptoms. Because the ultimate goal is to stop the spread of illness, the more detail and honesty provided, the better the investigation.

To protect privacy, confidentiality is always maintained throughout the contact tracing process. Contact tracers will never ask for Social Security Numbers, financial information or other unnecessary personal details.


  1. Hi,

    This is Melika and I am a certified illustrator.

    I was confused, to put it nicely, when I came across my images at your web-site. If you use a copyrighted image without my approval, you need to be aware that you could be sued by the owner.

    It’s not legal to use stolen images and it’s so disgusting!

    Take a look at this document with the links to my images you used at and my earlier publications to get evidence of my copyrights.

    Download it now and check this out for yourself:

    If you don’t delete the images mentioned in the document above within the next several days, I’ll write a complaint on you to your hosting provider stating that my copyrights have been infringed and I am trying to protect my intellectual property.

    And if it doesn’t work, you may be pretty damn sure I am going to report and sue you! And I will not bother myself to let you know of it in advance.

    • Melika,
      The photo on the story you cited comes from the free photo-sharing website Pixabay. On Pixabay, you are not listed as the owner of the image. I have a screen shot of the image on Pixabay, and I tried to email it to you, but the email you provided is not a working email. I’d be happy to talk to you more if you’ll email me at – Editor
