Here are some significant developments:
- Federal Reserve Chair Jerome H. Powell said the U.S. economy could be in store for a long and painful recession if Congress and the White House do not push more aid through soon.
- The Abbott coronavirus rapid-result test hailed by President Trump and used by the White House failed to detect infected samples in a large number of cases that were caught by a rival firm, a preliminary study says.
- Ordinary speech can emit small respiratory droplets that linger in the air for at least eight minutes and potentially much longer, according to a new study, which could help explain why infections so often cluster in confined spaces with limited air circulation.
- Some countries that had already reopened are closing down again after sudden spikes in infections. Among the latest: Saudi Arabia, which announced a total lockdown for the end of Ramadan after new cases soared during the holy month.
- The mayor of Washington, D.C., extended a stay-at-home order through June 8, and the entire capital region appeared likely to remain shut down.
