Covid-19: A wartime measure and who gets sick

The pandemic picture is becoming clearer, along with responses to it. As understanding who gets sick comes into sharper focus, experts emphasize one message: Millennials are not invincible. New CDC data show up to one-fifth of infected people ages 20 to 44 have been hospitalized, including 2% to 4% who required ICU treatment. And in Washington, the Trump administration invoked a wartime law to avert medical supply shortages.

More of the latest developments:

• The WHO announced it would launch a multiarm, multicountry trial for potential coronavirus therapies.
• Drug industry trade groups are pushing to ensure "shelter-in-place" orders make exceptions for biotech and pharma workers.
• Health workers across the country are increasingly afraid of protective gear shortages. Some are starting to scour for it on their own.
