Biology/Immunity Data and Metrics Infection and Spread Socializing Staying Safe Videos

Drs. Lindsey Leininger & Malia Jones tackle your COVID questions, including what’s up with curfews, immunity passes, and declining death rates. ➡️ Intro and website info (:00 – 3:59) ➡️ Lightning round (4:00 – 9:39) ➡️ Immunity: personal + herd (9:40 – 17:55) ➡️ Curfews to curb spread? (18:30 – 25:15) ➡️ Cases up, death Read more…

What do we currently know about SARS-CoV-2 re-infection?

Biology/Immunity Infection and Spread

A: So far it seems that short-term re-infection with SARS-CoV-2 is possible, but (hopefully) rare. A key question from the beginning of the pandemic has been what is the duration of immunity for SARS-CoV-2. Viruses like measles can provide lifelong immunity, but immunity to seasonal coronaviruses has generally been short-lived (around 12 months). One challenge Read more…

What does the new study from last week add to our knowledge about surface transmission of SARS-CoV-2?

Biology/Immunity Infection and Spread Staying Safe

Q: Do we need to wipe the groceries again? Thanks for this great question from Kat in LA and Katey in the UK. A: No need to return to grocery wiping, but wipe down your phone regularly and keep those hands clean. A new study released last week from the Commonwealth Scientific and Industrial Research Read more…

How can I boost my immune system?

Biology/Immunity Staying Safe

A: Today we focus on the importance of sleep health as an evidence-based strategy for improving your immune system during the COVID-19 pandemic. ** Long-term sleep deficiency is associated with a range of co-morbidities (type 2 diabetes, cardiovascular disease, dementia) that put you at higher susceptibility and more severe outcomes of COVID-19. You can reduce Read more…

What’s going on with the rise in SARS-CoV-2 cases in Spain? It sounds really bad.

Biology/Immunity Data and Metrics Infection and Spread

Q: Since they were already hit hard once, shouldn’t they have some herd immunity? A: Spain has seen an alarming increase in confirmed cases since mid-July, even surpassing the U.S. in daily cases per capita. But so far, deaths have only ticked up slightly compared to the height of their epidemic in March and April Read more…

Why do men suffer more severe COVID-19 and a higher risk of death? Do we know anything new?

Biology/Immunity Clinical Symptoms

A: Women may mount a stronger T cell response to SARS-CoV-2 infection, according to a recent paper in Nature from the lab of immunologist Dr. Akiko Iwasaki. In the study, researchers collected blood, saliva and other samples from 17 men and 22 women aged 60+ admitted to the hospital after a positive COVID-19 test and Read more…

I hear there has been a confirmed case of SARS-CoV-2 re-infection in Hong Kong?! How worried should I be?

Biology/Immunity Infection and Spread

A: Not very. In the words of immunologist Dr. Akiko Iwasaki, “This is no cause for alarm – this is a textbook example of how immunity should work.” What do we know? In a press release yesterday, researchers described the first confirmed case of re-infection in a 33-year old Hong Kong man returning from Spain. Read more…

Will staying isolated weaken our immune systems since we are not being exposed to other viruses like the common cold?

Biology/Immunity Families/Kids Staying Safe

A: Thank you for this great question from a follower. The immune system gets stronger by learning to differentiate between friendly microbes and unfriendly microbes. Friendly microbes are present in our daily environment in the dirt and in our homes. Bad microbes include viruses such as the common cold that can make us very sick. Read more…

What’s the deal with the news that COVID-19 immunity only lasts up to 3 months?

Biology/Immunity Infection and Spread Uncertainty and Misinformation

A: NOPE In a news story picked up by many media outlets yesterday, headlines regarding the duration of immunity were inferred from recent CDC guidance on quarantine. The relevant sentence from the CDC was: “People who have tested positive for COVID-19 do not need to quarantine or get tested again for up to 3 months Read more…

What is the real risk of death from COVID-19? Is it actually worse than the flu?

Biology/Immunity Infection and Spread Uncertainty and Misinformation

A: It’s complicated…. but YES! As a demographer and epidemiologist, mortality rates are in my wheelhouse so to speak, but getting a handle on COVID-19 has challenged us all. First some definitions: Case Fatality Rate (CFR): % of confirmed cases who die. In the U.S., the estimated CFR is currently 4.33% In the U.K., the Read more…
