Recently several friends on social media posted about settings on their phones for COVID-19 exposure notification. I checked and found it on my phone also. Early in the pandemic I read that this software was being developed for possible use in contact tracing but did not know it was now a reality.
I mentioned it to my computer guru husband Raymond who writes a tech blog Tech Savy Life and he researched and wrote an in-depth post about it. So I’m tapping into his knowledge to share with you.
What is contact tracing?
According to the CDC, contact tracing “helps protect you, your family, and your community” by
- Letting people know they may have been exposed to COVID-19 and should monitor their health for signs and symptoms of COVID-19.
- Helping people who may have been exposed to COVID-19 get tested.
- Asking people to self-isolate if they have COVID-19 or self-quarantine if they are a close contact.
Manual contact tracing done by humans is labor intensive and sometimes inefficient, requiring time on the phone trying to reach people, physically tracking them down, and then depending on their memory of where and with whom they have been. Using technology to do this speeds the process and improves accuracy, making it far more valuable and helpful.
Using case management tools
Local health departments may use digital case management tools to help make the contact tracing process more efficient. If you choose to provide information through one of these tools, your information is secure and stored with the health department. These tools help health departments quickly receive and analyze information about COVID-19.
Case management tools are under the same laws and regulations for all sensitive health information use (e.g. HIPPA). You must provide consent for the health department to collect information using a case management tool. Just like traditional contact tracing, digital tools will not collect information regarding money, Social Security numbers, bank account information, salary information, or credit card numbers.
Using exposure notification tools
Exposure notification tools may be an app that you can download on your personal cell phone. If you choose to download an exposure notification app for COVID-19, your information is secure.
Exposure notification apps are developed in collaboration with or endorsed by health departments. These apps undergo rigorous testing to determine their trustworthiness, security, and ability to protect people’s privacy. Until you give consent to share information with your local health department, any information you have entered into the app is stored only on your personal phone and is not sent to the health department or any other third party. The app and your information can be deleted any time.

Privacy and civil liberty issues
Again, according to the CDC,
There will not be a national app for contact tracing. There are many options available now, and it is up to each state and individual to decide which tools best fit their needs. It is up to you to decide if you download an exposure notification app for COVID-19.

Raymond’s article was written before the iOS update, but I recommend you read it for a more detailed explanation of how contact tracing works. And check out some of his other posts while you’re there.

exploring the HEART of health with technology
Even though computers and smart phones aren’t so “smart” sometimes (or maybe it’s just me) I’m glad we can harness the power of technology to help us explore and share the HEART of health. You may enjoy this post about how technology has changed the way we document healthcare for better and for worse.
The electronic medical record-asset or annoyance?
The increase in physician burnout has been directly linked to the introduction of electronic medical records.
Several states have now adopted use of contact tracing apps, but usefulness has been hampered by reluctance to use them.This article from Kaiser Health News explains why
