Preventing The Next Pandemic
Scientists saw the pandemic coming, but world leaders failed to listen. How can we prevent and minimize the next one?
COVID-19 and Excess Deaths
Excess deaths during the pandemic help tell a more complete picture of the impact of COVID-19.
COVID-19 “super-spreaders” and “super-spreading events”: The controversy
Evidence is emerging suggesting that COVID-19 does not spread equally. A minority of infected individuals seem to spread the virus easily to many people, while most infected individuals spread it to few others or no one at all, likely through a combination of circumstance, environment, and possibly biology. Why is this, and what does it mean for coronavirus containment strategies?
COVID-19 parties: Urban legend or real thing?
You've probably seen breathlessly scolding stories in the media about young people holding "COVID parties", in which attendees intentionally try to become infected with COVID-19.

Is COVID-19 transmitted by airborne aerosols?

What is this debate about, and, if coronavirus is airborne, should we be more scared?
Can Air Purifiers Stop Spread of COVID-19 Virus?
Air purifiers can remove droplets and viruses from the air, but they cannot prevent the spread of COVID-19 in a mass gathering.
Antivaccine leader Del Bigtree on COVID-19: “Let’s catch this cold!” Why antivaxxers and coronavirus conspiracy theorists are often one in the same.
Last week, antivaccine activist Del Bigtree posted a rant denying the severity of COVID-19, blaming the chronically ill for having made themselves vulnerable to severe disease through their lifestyle choices, and urging the young and healthy to "catch this cold". His rant shows exactly why COVID-19 conspiracy theorists and antivaxxers have such an affinity for each other and have teamed up to...
COVID-19 – The Second Wave
A second wave seems likely, but the evidence suggests our measures are working, and may even prevent a second wave.
