From 1976 to 2017, the Democratic Republic of the Congo experienced eight outbreaks of the deadly Ebola virus. Then, for 10 weeks earlier this year, the virus reemerged in the country, killing 33 people. Ministry of Health officials finally declared the crisis over on July 24. But just one week later, on August 1, the DRC reported a new outbreak of the Ebola virus in North Kivu province. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases at the The National Institutes of Health, joins Ira for an update on the latest outbreak of the Ebola virus in the Democratic Republic of the Congo. Plus, public health officials may not be able to control when and where a viral outbreak will occur. But, with the right strategy, they can keep it from becoming an epidemic. One of these strategies was used on yellow fever, a virus that emerged in Brazil last year and threatened major population centers like Sao Paulo and Rio de Janeiro. Nuno Faria of the University of Oxford describes how his team used real time genome sequencing of the Yellow Fever virus to track where it came from and which groups might be at risk. In the Southwest, water is at a premium, with every drop in demand from agriculture, industry, and growing populations. The Mexico-Texas border is no exception. Strict rules govern who can take water from the Rio Grande, with each country owing a certain amount of water to the other as the river winds back and forth. But the surface water isn’t the only liquid in play. Far below the surface, hidden aquifers straddle the border—and the water within them is largely unregulated. Rosario Sanchez of the Texas Water Resources Institute and Zoe Schlanger, environment reporter for Quartz discuss the water regulations and border disputes. Plus, are probiotics good for you?
