The biggest threats right now seem to be invisible, from the coronavirus itself to our inability to see loved ones in person, and our unspoken fears about the future. However, what is out of sight is not necessarily out of mind -- especially for psychologists like Laurie Santos. She joined Christiane via Skype with more on how to stay connected in a time of social distancing.

The UK Chancellor has just announced a package of economic support, increasing the government's pledges to ailing businesses to combat the COVID-19 crisis. Neel Kashkari, president of the Federal Reserve Bank of Minneapolis, oversaw the bailout program for the 2008 financial crisis. He now says his bank is acting "aggressively" to combat the COVID-19 crisis. He joins Christiane from Minneapolis.

Social restrictions are tightening around the U.S. to combat the spread of COVID-19, with millions on lockdown in California and the New York tri-state area under strict social distancing, and in some cases curfews. New Jersey Governor Phil Murphy joins Christiane to talk about how he's working to flatten the curve as the numbers keep rising.

Coronavirus was the main event in last night's Democratic debate: an eerily quiet one-on-one between Bernie Sanders and Joe Biden, that took place without an audience and started with an elbow bump. COVID-19 has truly reshaped the political race of 2020.

There are an estimated 170,000 confirmed cases of COVID-19 across the world, and the death toll has jumped to more than 6,400.

Christiane is joined by New York City Health Commissioner Dr. Oxiris Barbot for an update on the crisis.

The financial fallout of the epidemic is dramatic, with grim headlines predicting a deep global recession. Harvard Kennedy school professor Jason Furman was a top economic advisor to President Barack Obama during the last meltdown -- the financial crisis of 2008.

While other countries struggle to contain the virus, the UK has been an outlier, remaining open -- but now it's doing an about-face. Prime Minister Boris Johnson is turning against mass gatherings, urging people to "stop all unnecessary social contact." Will this be enough to counter the disease? Christiane speaks to a doctor on the front lines, Dr. Sonia Adesara.

MIT professor David Autor is a leading economist studying disruptions to labor markets. His work covers everything from globalization to trade, and, as it turns out, viruses. Autor talks with Walter Isaacson about U.S.-China trade relations and the long-term impact of the coronavirus.

Top federal health official Dr. Anthony Fauci says this is just the beginning of the coronavirus.

David Urban is an advisor to President Trump's 2020 campaign. He joins Christiane to discuss.

Over ten thousand cases of coronavirus are confirmed in Italy and the death toll is increasing at an alarming rate. Offering a stark warning for the United States and the rest of the world is former Italian Prime Minister Matteo Renzi, who joins Christiane from Rome.

Ted Olson is the former U.S. Solicitor General who fought high-profile cases like Bush v.

He joins Walter Isaacson to explain why he supports this cause.

President Trump and Congress are trying to hammer out a financial package to stave off the worst of the coronavirus economic impact and its effect on vulnerable workers. As Democrats prepared to try to reach a compromise with Republicans and the White House, Christiane spoke with Chair of the House Intelligence committee Adam Schiff about what the nation can expect.

According to government data, 10 women are killed every day in Mexico. On Sunday, to mark International Women's Day, tens of thousands marched to protest the Mexican government's inaction. On Monday, they took a giant leap forward, leaving offices and work spaces in a mass strike. Journalist Lydia Cacho joins Christiane to discuss this crucial moment in history.

Christiana Figueres, the architect of the 2015 Paris Agreement, has dedicated her life to climate policy.

On one of the most stunning days since the global financial crisis of 2008, markets plunged so deeply that trading on the NYSE had to be briefly suspended.

He joins Christiane to discuss the situation.

We've all seen the guidance about frequently washing our hands for 20 seconds, and have heard about panic-buying at supermarkets. But what's really going to keep us safe in the coronavirus outbreak? If anyone knows, it's Dr. Bruce Aylward. He is Senior Advisor to the Director-General of the World Health Organization and led the WHO’s team in China.

Yale law professor Daniel Markovits says the system that values hard work and promotes the American dream is in itself a sham. He is taking aim at the very structure that made him a success in his latest book, "The Meritocracy Trap." He joins Hari Sreenivasan to discuss.

Despite progress in key areas like the #MeToo movement, women's rights appear to be backsliding in much of the world. In her new book, Helen Lewis takes a look at the complicated, often deeply flawed heroes who broke through the barriers to give women the right to vote, divorce, work, and participate in team sports, among other advances. She discusses with Christiane.

Tyll Ulenspiegel is a German mythological figure who crosses political and social boundaries, exposing their hypocrisy. In his new novel, author and playwright Daniel Kehlmann brings this fictitious character to life against the backdrop of the Thirty Years' War, one of the darkest periods in Central European history. He tells Christiane how he immersed himself in this unusual world.

State Senator Peter Harckham is a freshman Democratic lawmaker who, during a news conference in January, unexpectedly admitted that he had battled with addiction.
