With all this holiday travel, why don’t airports have COVID-sniffing dogs?
Data and Metrics Testing and Contact Tracing
Lauren Hale, PhD MA
A: As noted in prior posts, highly trained dogs have the incredible capacity to successfully detect the odor of people with COVID-19 by sniffing human sweat. Pilot programs using COVID-sniffing dogs to detect infection among potential passengers have already launched in airports in Finland, the United Arab Emirates, and most recently Chile. These pilot projects Read more…
Why are COVID-19 numbers lower on the weekends?
Data and Metrics Data Literacy Testing and Contact Tracing
Lauren Hale, PhD MA
A: TL, DR: The weekly pattern of fewer COVID-19 cases and deaths on the weekends is primarily due to differences in testing timing and reporting delays, but some of the pattern may be due to increased weekend socializing. Based on publicly available data, there is a widely observed ‘weekend effect’ with fewer COVID-19 cases and Read more…
What’s up with the new CDC guidelines for shorter quarantine periods?
Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: The guidelines represent a “most bang for your buck” approach to preventing transmission of COVID-19 at the population level–but quarantining for 14 days is still the recommended and safest approach. While our scientific understanding of how long it takes to develop COVID-19 symptoms after being exposed (science term: incubation period) still says up to Read more…

I heard there was a large COVID-19 outbreak at an overnight summer school retreat in WI. What happened?!
Infection and Spread Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: Retreat organizers relied primarily on a test-based strategy for preventing individuals with COVID-19 from attending the retreat and didn’t employ other measures to prevent transmission of COVID-19 among attendees. This did not work. Consequently, a single attendee who became ill the day after arriving led to 116 other attendees (76% of attendees) becoming a Read more…
Does the new CDC guidance about avoiding 15 minutes cumulative contact mean with masks or without masks?
Infection and Spread Masks Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: In the community setting, someone who meets the criteria for being a close contact to a case of COVID-19, meets the criteria REGARDLESS of whether or not they or the case had on a mask. Why is someone considered a close contact regardless of whether they had on a mask? While cloth masks are Read more…

Why wasn’t a test-only strategy sufficient for preventing transmission of COVID-19 in the White House?
Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: Testing individuals for COVID-19, while a necessary component of our public health strategy, doesn’t 100% prevent those who are infected with SARS-CoV-2 from transmitting the infection to others BEFORE they test positive. The type of testing strategy used by the White House was to screen individuals for COVID-19 using a rapid antigen-based test (i.e., Read more…
What do epidemiologists think about Joe Biden and Mike Pence (and other national leaders) testing negative for COVID on Friday?
Testing and Contact Tracing
Malia Jones, PhD MPH
A: A negative test result does NOT mean that Mr. Pence and Mr. Biden are COVID-free… even if that happens to be really inconvenient for them. Everyone who has been near the President of the United States in the last week (or who has been around anyone else with COVID-19 for that matter) should self-quarantine Read more…

New Rapid Home Test for COVID-19
Infection and Spread Testing and Contact Tracing
Aparna Kumar, PhD CRNP MPH
Q: I heard that the FDA approved several new rapid home test for diagnosis of COVID-19. Are the rapid tests just as good as the others? Can I take this one before I visit family? A: TL; DR: No, rapid tests are not quite as good at picking up positives (someone who really has COVID-19) Read more…
What lessons can we learn from the contact tracers?
Testing and Contact Tracing
Malia Jones, PhD MPH
We talked to someone who has been working as a state contact tracer since May. She gave us a list of practical things you can do today to make contact tracers’ jobs easier: 1️⃣ Clear out your voicemail so they can leave a message! 📪 2️⃣ Make sure you have a thermometer at home. 🌡️ Read more…
With all this holiday travel, why don’t airports have COVID-sniffing dogs?
Data and Metrics Testing and Contact Tracing
Lauren Hale, PhD MA
A: As noted in prior posts, highly trained dogs have the incredible capacity to successfully detect the odor of people with COVID-19 by sniffing human sweat. Pilot programs using COVID-sniffing dogs to detect infection among potential passengers have already launched in airports in Finland, the United Arab Emirates, and most recently Chile. These pilot projects Read more…
Why are COVID-19 numbers lower on the weekends?
Data and Metrics Data Literacy Testing and Contact Tracing
Lauren Hale, PhD MA
A: TL, DR: The weekly pattern of fewer COVID-19 cases and deaths on the weekends is primarily due to differences in testing timing and reporting delays, but some of the pattern may be due to increased weekend socializing. Based on publicly available data, there is a widely observed ‘weekend effect’ with fewer COVID-19 cases and Read more…
What’s up with the new CDC guidelines for shorter quarantine periods?
Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: The guidelines represent a “most bang for your buck” approach to preventing transmission of COVID-19 at the population level–but quarantining for 14 days is still the recommended and safest approach. While our scientific understanding of how long it takes to develop COVID-19 symptoms after being exposed (science term: incubation period) still says up to Read more…
Has my COVID bubble gotten out of control? How can I tell?
Families/Kids Infection and Spread School Socializing Staying Safe Testing and Contact Tracing
Malia Jones, PhD MPH
A: Your “bubble” might be far bigger than you think. To figure out exactly how big and who you might be sharing germs with, think like a contact tracer and sketch out your contact network. 🖧 If you need to pull out a piece of paper to figure this out, that’s a whole lot of Read more…
Why are universities doing things like testing wastewater and pooling spit?
Testing and Contact Tracing
Lauren Hale, PhD MA
A: Testing samples of wastewater and pooled spit in places with communal living, such as colleges and universities, provide several valuable benefits in detecting COVID-19. TESTING OF ASYMPTOMATIC PEOPLE. When people are living and socializing together in the same building, there is a risk of asymptomatic spread. If you wait until people are symptomatic to Read more…
I heard there was a large COVID-19 outbreak at an overnight summer school retreat in WI. What happened?!
Infection and Spread Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: Retreat organizers relied primarily on a test-based strategy for preventing individuals with COVID-19 from attending the retreat and didn’t employ other measures to prevent transmission of COVID-19 among attendees. This did not work. Consequently, a single attendee who became ill the day after arriving led to 116 other attendees (76% of attendees) becoming a Read more…
Does the new CDC guidance about avoiding 15 minutes cumulative contact mean with masks or without masks?
Infection and Spread Masks Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: In the community setting, someone who meets the criteria for being a close contact to a case of COVID-19, meets the criteria REGARDLESS of whether or not they or the case had on a mask. Why is someone considered a close contact regardless of whether they had on a mask? While cloth masks are Read more…
I can’t help but notice how well Maine is controlling COVID-19. What’s their secret? Rural state? Rich state? Not many older people?
Data and Metrics Infection and Spread Testing and Contact Tracing
Alison Buttenheim, PhD MBA, Co-founder & Advisor
A: Nope to those three, but yes to leadership, preparation, testing & tracing, and calm, science-based communication. It’s true: Maine is doing very well by almost all metrics used to track the epidemic. While 21 states had their highest daily case counts in the last 3 weeks, Maine’s single day record cases happened way back Read more…

Testing and Contact Tracing
Malia Jones, PhD MPH
Q: Jennifer from Texas asks: Are there really false-positives from COVID tests? If so, how is it possible for a test to pick up something that is not there? A: Yep, they exist. High-profile false-positive COVID tests are making the news again after Michael Burton of the New Orleans Saints erroneously tested positive the day Read more…
Why wasn’t a test-only strategy sufficient for preventing transmission of COVID-19 in the White House?
Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: Testing individuals for COVID-19, while a necessary component of our public health strategy, doesn’t 100% prevent those who are infected with SARS-CoV-2 from transmitting the infection to others BEFORE they test positive. The type of testing strategy used by the White House was to screen individuals for COVID-19 using a rapid antigen-based test (i.e., Read more…
What do epidemiologists think about Joe Biden and Mike Pence (and other national leaders) testing negative for COVID on Friday?

Malia Jones, PhD MPH
A: Your “bubble” might be far bigger than you think. To figure out exactly how big and who you might be sharing germs with, think like a contact tracer and sketch out your contact network. 🖧 If you need to pull out a piece of paper to figure this out, that’s a whole lot of Read more…
Why are universities doing things like testing wastewater and pooling spit?
Testing and Contact Tracing
Lauren Hale, PhD MA
A: Testing samples of wastewater and pooled spit in places with communal living, such as colleges and universities, provide several valuable benefits in detecting COVID-19. TESTING OF ASYMPTOMATIC PEOPLE. When people are living and socializing together in the same building, there is a risk of asymptomatic spread. If you wait until people are symptomatic to Read more…
I heard there was a large COVID-19 outbreak at an overnight summer school retreat in WI. What happened?!
Infection and Spread Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: Retreat organizers relied primarily on a test-based strategy for preventing individuals with COVID-19 from attending the retreat and didn’t employ other measures to prevent transmission of COVID-19 among attendees. This did not work. Consequently, a single attendee who became ill the day after arriving led to 116 other attendees (76% of attendees) becoming a Read more…
Does the new CDC guidance about avoiding 15 minutes cumulative contact mean with masks or without masks?
Infection and Spread Masks Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: In the community setting, someone who meets the criteria for being a close contact to a case of COVID-19, meets the criteria REGARDLESS of whether or not they or the case had on a mask. Why is someone considered a close contact regardless of whether they had on a mask? While cloth masks are Read more…
I can’t help but notice how well Maine is controlling COVID-19. What’s their secret? Rural state? Rich state? Not many older people?
Data and Metrics Infection and Spread Testing and Contact Tracing
Alison Buttenheim, PhD MBA, Co-founder & Advisor
A: Nope to those three, but yes to leadership, preparation, testing & tracing, and calm, science-based communication. It’s true: Maine is doing very well by almost all metrics used to track the epidemic. While 21 states had their highest daily case counts in the last 3 weeks, Maine’s single day record cases happened way back Read more…
Are there really false positives from COVID tests?
Testing and Contact Tracing
Malia Jones, PhD MPH
Q: Jennifer from Texas asks: Are there really false-positives from COVID tests? If so, how is it possible for a test to pick up something that is not there? A: Yep, they exist. High-profile false-positive COVID tests are making the news again after Michael Burton of the New Orleans Saints erroneously tested positive the day Read more…
Why wasn’t a test-only strategy sufficient for preventing transmission of COVID-19 in the White House?
Testing and Contact Tracing
Amanda Simanek, PhD MPH
A: Testing individuals for COVID-19, while a necessary component of our public health strategy, doesn’t 100% prevent those who are infected with SARS-CoV-2 from transmitting the infection to others BEFORE they test positive. The type of testing strategy used by the White House was to screen individuals for COVID-19 using a rapid antigen-based test (i.e., Read more…
What do epidemiologists think about Joe Biden and Mike Pence (and other national leaders) testing negative for COVID on Friday?
Testing and Contact Tracing
Malia Jones, PhD MPH
A: A negative test result does NOT mean that Mr. Pence and Mr. Biden are COVID-free… even if that happens to be really inconvenient for them. Everyone who has been near the President of the United States in the last week (or who has been around anyone else with COVID-19 for that matter) should self-quarantine Read more…
What’s the update with COVID-19-sniffing dogs?
Reopening Testing and Contact Tracing Travel
Lauren Hale, PhD MA
A. The Helsinki-Vantaa airport welcomed COVID-19-sniffing dogs to their staff last week, hoping to use their keen sense of smell to detect COVID-19 positive patients up to 5 days before symptoms appear. Dubai International Airport also has a team of dogs sniffing for COVID-19. Here’s how the airport testing works: Prospective passengers rub a wipe Read more…
A: The guidelines represent a “most bang for your buck” approach to preventing transmission of COVID-19 at the population level–but quarantining for 14 days is still the recommended and safest approach. While our scientific understanding of how long it takes to develop COVID-19 symptoms after being exposed (science term: incubation period) still says up to Read more…
