This week, the world’s attention has turned to the spread of the novel coronavirus, SARS-CoV-2, that was first detected in Wuhan, China, late in 2019. More countries are finding cases, and in the United States, a California patient has become the first known case of possible “community spread”—where the patient had not traveled to affected areas or had known exposure to someone who had been infected. On Tuesday, the Centers for Disease Control said Americans should prepare for “significant disruption” and “inevitable” spread of the virus in the U.S. And on Wednesday, President Trump announced that Vice President Mike Pence would head the country’s coronavirus response. But what does preparation actually look like for healthcare systems that will be on the frontlines of detecting and responding to any new cases? Ira talks to infection prevention epidemiologist Saskia Popescu and public health expert Jennifer Nuzzo about the practical steps of preparing for a new pathogen, including expanding testing and making sure healthcare workers have necessary protective equipment. Plus, they address why childcare, telecommuting, and community planning may be more important than face masks for individuals who are worried about what they can do. Facebook is a household name globally with nearly 2 billion users. Mark Zuckerberg’s goal was to connect the entire world online when he founded the company in 2006. But 14 years later, Facebook has evolved into more than a social media platform. The company has been involved in debates and scandals around user privacy, outside interference in elections, and the spread of fake news. Last summer, the Federal Trade Commission fined Facebook $5 billion for “repeatedly used deceptive disclosures and settings to undermine users’ privacy preferences in violation of its 2012 FTC order.” Journalist Steven Levy has been following Zuckerberg and the company since the beginning. In his new book Facebook: The Inside Story he chronicles Zuckerberg’s growth and data-driven approach and how that influenced the tactics the company applied to the problems that resulted from the platform.
