Good morning and welcome to what's another work-at-home week for many of us. I'm Elizabeth Cooney and I'll be bringing you this newsletter for a few more days.

Covid-19: Gilead pauses access to experimental drug and a president odds with medical experts

Gilead Sciences has temporarily stopped granting patients access (with some exceptions) to remdesivir, its experimental drug against the novel coronavirus that causes Covid-19, citing “overwhelming demand.” And while hope has emerged around two anti-malaria drugs, chloroquine and hydroxychloroquine, President Trump is at odds with his medical experts over using the drugs against Covid-19.

More developments:

• A dozen physicians at the epicenter of Italy’s Covid-19 outbreak issued a plea to the rest of the world: Because hospitals “are themselves becoming sources of [coronavirus] infection,” they urge other countries to deliver care to many patients in their homes. 
• Sen. Rand Paul (R-Ky.) said he has tested positive for the disease caused by the new coronavirus, becoming the first member of the Senate to report a case of Covid-19. Two House members, Reps. Mario Diaz Balart (R-Fla.) and Ben McAdams (D-Utah),  have tested positive.
• The FDA warns that new at-home coronavirus tests are “unauthorized” while some of the startups selling them insist they are permitted under government rules loosened to expand desperately needed testing for Covid-19.
• A coronavirus test from Cepheid will make only a small dent in the number of diagnostic tests available. It's not meant for the worried well.
• Courage alone isn't enough for health care workers to get through the Covid-19 pandemic, Adam Levine writes in a First Opinion. He speaks from experience: He fought Ebola in 2014. 
• Across the country, health care workers aren't being given the proper equipment to stay safe while treating patients. Give them what they need to fight Covid-19, Jennifer Hushion says in a First Opinion.
