What accounts for the recent drop in COVID-19 cases in the US?
Data and Metrics Infection and Spread
Alison Buttenheim, PhD MBA, Co-founder & Advisor
Q: It looks like Covid-19 infection rates have dropped significantly in the US since the vaccine became available. Is the vaccine already having an impact? What else would account for the drop?” A: Of all the possible explanations — vaccination, immunity from prior infection, behavior change, seasonality, and less testing — the best answer seems to Read more…
Why don’t we know whether vaccinated people can still spread the virus?
Infection and Spread Vaccines
Amanda Simanek, PhD MPH
Q: What is holding us back from knowing whether those who have been vaccinated can still be carriers of the virus and spread it to others? A: COVID-19 vaccine trials were designed to measure how well they protect people from developing moderate to severe disease, not how well they prevent spread of the virus to Read more…

Does in-person schooling contribute to COVID-19 spread?
Infection and Spread School
Jennifer Beam Dowd, PhD
A: It’s complicated. TL;DR: Two new well-designed studies find evidence that in-person schooling *does not* contribute to COVID spread when baseline community spread is LOW, but that in-person schooling *does* contribute to worsening COVID metrics when baseline COVID transmission is high. Thus far the research on schools and COVID-19 has been quite muddy, but two Read more…

What new information do we have about the B.1.1.7 variant?
Biology/Immunity Infection and Spread Vaccines
Ashley Ritter, APRN, PhD
A: This is an evolving situation. Actions today could result in great success or tragic loss. Key take aways— B.1.1.7 is in the US. Growing evidence suggests the B.1.1.7 variant spreads more easily than previous variants. New evidence supports the hypothesis that current vaccines are effective against B.1.1.7. Early efforts to contain B.1.1.7 buys time Read more…
Are usual precautions effective against new strain of COVID-19?
Infection and Spread Staying Safe
Jennifer Beam Dowd, PhD
Q: The new coronavirus strain is more transmissible than the older strain. Does this mean our usual precautions (masks, 6 foot distance, being outside) are less effective? A: Luckily, no. Virus mutations still don’t defy the laws of physics. But we need to be more vigilant about existing precautions. The new variant is transmitted the 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…
I’m reading that the new strain of COVID-19 is 70% more transmissible. What does this mean? How transmissible was the first strain?
Infection and Spread
Malia Jones, PhD MPH
A: “Transmissibility” in infectious disease means how readily it is passed from one person to another, given the peculiarities of a specific time and place (in this case, in the UK this Fall). Transmissibility is measured in numbers with something called R-value. The R-value for the old SARS-CoV-2 variant was hovering right around 1 (in Read more…

Does someone who has been vaccinated still need to wear a mask and take other precautions?
Infection and Spread Vaccines
Jennifer Beam Dowd, PhD
A: Yes. We don’t yet know whether the vaccines prevent someone from being infectious. The existing COVID-19 vaccine trials focused on a specific endpoint – symptomatic COVID-19 disease. We know that both the Pfizer and Moderna vaccines were close to 95% efficacious in preventing disease (YAY!!). But wouldn’t we expect the vaccine to also stop Read more…
What did we learn from the recent study of COVID-19 transmission in a Korean restaurant?
Infection and Spread
Jennifer Beam Dowd, PhD
A: Indoor dining can be risky, even for a short duration & distance beyond 6 feet/2 meters. #StopSwappingAir In a recent study from South Korea, a high school student was infected in a 5-minute window of time and sitting 20 feet away from the “index” case. How do they know this with such precision? While Read more…
How can I minimize COVID-19 transmission when riding a car?
Infection and Spread
Jennifer Beam Dowd, PhD
A: Open up those windows, mask up, and keep the duration short. Physicists from UMass Amherst recently used simulations of airflow patterns within car interiors to study the best way to minimize transmission risk during ride-share style car rides. The car geometry was based on a Toyota Prius traveling 50 mph. Key results: ➡️ Opening Read more…
Why can’t I ditch the masks and distancing if I already recovered from Covid-19?
Infection and Spread Vaccines
Ashley Ritter, APRN, PhD
A: Recovering from Covid-19 provides some immunity, but the strength and length of time you keep that immunity are not consistent from person to person. Think of your Covid-19 immunity as an unlabeled bottle of sunscreen. The level of protection provided is hard to predict. Sunscreen is designed to reduce the amount of UVA and Read more…
Is there really a risk of COVID-19 transmission at the gym?
Infection and Spread Staying Safe
A: Unfortunately, yes. While we appreciate the importance of exercise for our physical and mental health, there HAVE been documented instances of COVID-19 spread in gyms and fitness studios, and they are home to one of the conditions that makes transmission easier: a lot of shared indoor air. In the infographic below from Fraser Health Read more…

A: “Transmissibility” in infectious disease means how readily it is passed from one person to another, given the peculiarities of a specific time and place (in this case, in the UK this Fall). Transmissibility is measured in numbers with something called R-value. The R-value for the old SARS-CoV-2 variant was hovering right around 1 (in Read more…
Dear Pandemic COVID Q&A
Biology/Immunity Infection and Spread Vaccines Videos
Malia Jones, PhD MPH
In this live Q&A, Drs. Malia Jones & Amanda Simanek will be tackling pandemic questions from our readers. We’ll take questions about the “mutant strain”, which vaccine is best, that rumor about asymptomatic transmission being a phantom, and what we know (and don’t) about whether someone can still spread COVID after being vaccinated. ➡️ Welcome Read more…
Does someone who has been vaccinated still need to wear a mask and take other precautions?
Infection and Spread Vaccines
Jennifer Beam Dowd, PhD
A: Yes. We don’t yet know whether the vaccines prevent someone from being infectious. The existing COVID-19 vaccine trials focused on a specific endpoint – symptomatic COVID-19 disease. We know that both the Pfizer and Moderna vaccines were close to 95% efficacious in preventing disease (YAY!!). But wouldn’t we expect the vaccine to also stop Read more…
What did we learn from the recent study of COVID-19 transmission in a Korean restaurant?
Infection and Spread
Jennifer Beam Dowd, PhD
A: Indoor dining can be risky, even for a short duration & distance beyond 6 feet/2 meters. #StopSwappingAir In a recent study from South Korea, a high school student was infected in a 5-minute window of time and sitting 20 feet away from the “index” case. How do they know this with such precision? While Read more…
How can I minimize COVID-19 transmission when riding a car?
Infection and Spread
Jennifer Beam Dowd, PhD
A: Open up those windows, mask up, and keep the duration short. Physicists from UMass Amherst recently used simulations of airflow patterns within car interiors to study the best way to minimize transmission risk during ride-share style car rides. The car geometry was based on a Toyota Prius traveling 50 mph. Key results: ➡️ Opening Read more…
Why can’t I ditch the masks and distancing if I already recovered from Covid-19?
Infection and Spread Vaccines
Ashley Ritter, APRN, PhD
A: Recovering from Covid-19 provides some immunity, but the strength and length of time you keep that immunity are not consistent from person to person. Think of your Covid-19 immunity as an unlabeled bottle of sunscreen. The level of protection provided is hard to predict. Sunscreen is designed to reduce the amount of UVA and Read more…
Is there really a risk of COVID-19 transmission at the gym?
Infection and Spread Staying Safe
A: Unfortunately, yes. While we appreciate the importance of exercise for our physical and mental health, there HAVE been documented instances of COVID-19 spread in gyms and fitness studios, and they are home to one of the conditions that makes transmission easier: a lot of shared indoor air. In the infographic below from Fraser Health Read more…
A: This is an evolving situation. Actions today could result in great success or tragic loss. Key take aways— B.1.1.7 is in the US. Growing evidence suggests the B.1.1.7 variant spreads more easily than previous variants. New evidence supports the hypothesis that current vaccines are effective against B.1.1.7. Early efforts to contain B.1.1.7 buys time Read more…
Are usual precautions effective against new strain of COVID-19?
Infection and Spread Staying SafeJennifer Beam Dowd, PhD
Q: The new coronavirus strain is more transmissible than the older strain. Does this mean our usual precautions (masks, 6 foot distance, being outside) are less effective? A: Luckily, no. Virus mutations still don’t defy the laws of physics. But we need to be more vigilant about existing precautions. The new variant is transmitted the 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…
