So far, more than 300,000 people globally are known to have died because of the coronavirus. The U.S. is fast approaching the grim milestone of 100,000 fatalities. And as shocking as those numbers are, experts believe there are actually many more deaths we’re not counting. We need to understand how fast, and in what groups, mortality is rising, in order to fine-tune the policies that govern our response to the virus. Jason Gale reports that experts are looking past the official count to find other ways to investigate just how many people are dying.

Knowing how many people are being tested for coronavirus is essential for getting an accurate picture of the spread of the virus. But the government hasn’t readily provided this data. Instead, experts, media outlets and even the Trump administration have turned to a surprising source for these numbers: A volunteer effort by a team of journalists, called the Covid Tracking Project. Emma Court reports on what we're learning from the project.

There's an innovative, but risky way we could speed up development of a COVID-19 vaccine. Some scientists argue we should intentionally infect volunteers with the coronavirus to get a vaccine sooner. How would it work? Today's special episode is a collaboration with Tradeoffs, a podcast about our costly, complicated and counter-intuitive health care system. Tradeoffs' Dan Gorenstein explores how scientists could ethically and safely infect people to speed up the fight against COVID-19.

There’s a growing public health argument about how people should calculate risk when it comes to social distancing. Many states are now lifting stay-at-home restrictions, summer is around the corner, and people in the third month of what many hoped would be a weeks-long disruption are desperate to visit friends and get outside. That means we will be socializing a lot more--in many cases, without clear guidelines as to what’s really risky. Kristen V. Brown reports that as we learn more about how the virus spreads, and what constitutes risky behavior, messaging from experts will have to become a little more nuanced than just “stay home, stay safe.”

Covid-19 has sparked an unprecedented mobilization of researchers looking to create a drug that can stem the spread of the virus. Globally, drug developers are working on as many as 100 experimental vaccines. But as nations rush to ease lockdowns and restart economies, some countries seem to want to secure early supplies of a vaccine for themselves. James Paton reported on efforts to democratize international access to vaccines, and the dangers of creating immunization gaps.

The Internet has been teeming with theories about the origin of the coronavirus. Scientists have been saying for more than three months that it most likely originated in a species of bat found in the south of China, and then managed to somehow jump into people. But alternative explanations have been floated. United States Secretary of State Mike Pompeo has repeatedly blamed China, and specifically a laboratory in Wuhan that was researching dangerous viruses. Jason Gale talked to a World Health Organization scientist to tease out the most plausible explanation for where the virus came from.
