The coronavirus outbreak is impacting global business

The coronavirus, first detected in central China more than a month ago, has now reached more than 20 other countries. The outbreak is disrupting business from global supply chains to the film industry to tourism. And, US President Donald Trump has added six more countries to his travel restrictions list — four out of the six are African countries. Some activists are calling this an "Africa ban." Also, attention turns to Iowa on Monday with the first contest of the 2020 election season. The World's Rupa Shenoy reports on immigrant teens who are trying to make sure that climate change is top of mind as Iowans come out to caucus.
