The latest Nearly 1 in 3 Americans traveled to work in recent weeks, a Washington Post-Ipsos poll found — and most of them are worried about the virus following them home. More than one-third of those going to work said they or someone in their household had a serious chronic illness, and roughly the same amount said they had probably been exposed to covid-19 on the job. And as with so many other effects of the pandemic, the stress is falling unequally on nonwhites. “Like gambling with dice,” a 58-year-old prison worker in Virginia said in our story on the poll. And yet, more and more Americans are going back to work — often under widely disparate rules as governors unilaterally roll back quarantine measures. States don't even agree on what temperature constitutes a fever. A worker sent home with a 99.5-degree temperature in Delaware would be allowed to work in Texas, Georgia, Ohio or Pennsylvania, The Post reported. The federal government has offered little guidance. After weeks of delay, the Centers for Disease Control and Prevention on Thursday issued a scant six pages of recommendations to guide schools and businesses on when and whether to reopen after the White House declined to publish much more detailed CDC recommendations prepared last month. It is the latest sign of the increasing tension between the White House and the world-renowned public health agency. A new study suggests that lifting quarantines quickly could lead to a huge viral surge. Researchers from several American universities looked at about 1 million confirmed coronavirus cases in March and April, and estimated that areas without shelter-in-place orders had potentially 10 times more virus spread — or 35 times more in areas with no social distancing guidelines at all. Ever wondered how researchers predict how the virus will spread over time? We have a new tool that lets you play epidemiologist and make your own models to understand how the pros do it. So far, covid-19 appears to be a disease of the relatively rich, spreading predominantly in developed countries such as the United States. But experts think the pandemic's chaos will devastate the world's poor, even if the virus spares them. The World Food program estimates the number of people facing acute hunger will double this year to 265 million. A U.N. study says more than a half billion people could become impoverished. And already, nearly half the global workforce has lost their jobs.

The pandemic could permanently change urban life, as small businesses in high-rent cities such as Washington are wiped out. House Democrats moved toward passage of a $3 trillion tax cut and spending bill Friday, but the White House and Republicans promised to block it. The chamber is also poised to adopt historic changes that would allow remote voting during the pandemic. President Trump announced Friday that an Army general and the former head of vaccines at GlaxoSmithKline will lead his Operation Warp Speed program to manufacture a vaccine for the virus by January — a timeline many experts doubt is possible.
