The coronavirus pandemic has struck the globe during an era of massive refugee crises, confrontation among the world's great powers and armed conflicts in many countries. Under these circumstances, how do we coordinate an effective global response to an enemy we can't see? To answer that question and more, Judy Woodruff turns to Antonio Guterres, secretary-general of the United Nations.

Louisiana is one of the country's emerging coronavirus hot spots. New Orleans alone has over 1,100 cases and 119 deaths, and the city's convention center is being converted into a makeshift hospital to provide care amid the outbreak. William Brangham talks to Dr. Julio Figueroa of Louisiana State University Health about why residents of the state may be at greater risk of becoming seriously ill.

The State Department says it has brought back 15,000 Americans who were stranded in more than 30 countries across the globe. But some 30,000 are still stuck abroad, growing increasingly worried about border closures, food shortages and health care systems that are becoming overwhelmed. Nick Schifrin reports on the immense challenge of trying to return home amid a global pandemic.

Confirmed coronavirus infections have passed the half-million mark worldwide, with 23,000 deaths. In the U.S., a huge economic relief bill is nearing final approval amid an unprecedented wave of unemployment claims from people who have lost their jobs due to the pandemic. And hospitals are strained to the point of collapse. Amna Nawaz reports and Lisa Desjardins joins Judy Woodruff to discuss.

Wednesday's huge rise in unemployment claims dwarfs all historical records in the U.S. Although nearly 3.3 million filed, many economists say the number still doesn't reflect the full scope of people who have been laid off or furloughed or are losing their businesses. We asked Americans to share their stories of the struggles they are facing right now. Here is a sampling of what we heard.

Former Treasury Secretary Lawrence Summers has deep experience in economic policy. On Wednesday, he was among a bipartisan group of economic experts urging U.S. officials to prioritize resolving the pandemic's medical emergency before trying to rectify its economic fallout. Summers joins Judy Woodruff to discuss direct payments to Americans, funding hospitals and the need for consistent strategy.

More U.S. hospitals are feeling the pressure and gravity of the spread of COVID-19. In New York state, hospitalizations rose 40 percent and 100 patients died in a single day. As the influx grows, some hospitals and medical practitioners are taking extraordinary steps to cope and prepare for the worsening crisis. William Brangham talks to Stony Brook University Hospital's Carol Gomes.

President Trump recently announced strict new border controls, citing concerns over the coronavirus pandemic. Officials will now turn away most migrants entering the country from the U.S.-Mexico border -- including people coming legally and fleeing violence. Jean Guerrero of KPBS spoke to families stuck in limbo at the country's busiest land border crossing, just south of San Diego in Tijuana.

Many Americans are staying home amid the coronavirus pandemic. But what does that mean for those who aren't safe where they live? John Yang talks to Katie Ray-Jones, CEO of the National Domestic Violence Hotline, about how abusers may leverage a broader societal crisis to exact further control and why physical distancing puts victims of abuse at even greater risk.

President Trump's Coronavirus Task Force held another news briefing on Thursday evening, at which Trump reiterated his desire to sign the Senate's new pandemic economic aid package into law. But Trump continues to differ from state governments and health officials regarding a timeline for relaxing physical distancing. Yamiche Alcindor was there, and she joins Judy Woodruff to discuss.
