Infectious diseases may be spreading more quickly, thanks to global warming. Viruses that were kept in check by the polar ice box are being released. And as some animals move north to keep cool, they're bringing all sorts of parasites with them, from microbes to ticks. Christopher Solomon has written about this in the August issue of "Scientific American." And he joins me now from Montana Public Radio in Missoula. Welcome.
This is WEEKEND EDITION from NPR News. I'm Arun Rath. The worst Ebola outbreak ever recorded continues to spread in West Africa. And medical workers in Sierra Leone have responded by expanding an extraordinary field hospital. It opened less than a month ago, but it now has the largest Ebola isolation unit ever built, with 64 beds. NPR's Jason Beaubien visited and describes for us the infection control measures that go into treating this highly contagious disease.
Hamas militants fired rockets into Israel today, more rockets, after the Israeli government announced it was expanding ground operations in the Gaza Strip. Thousands of Palestinians continue to flee their homes. Early this morning, some, still wearing their pajamas, left in haste to take shelter in local schools. Those schools are already packed beyond capacity. NPR's Emily Harris reports on the increasingly dire situation.
And for some insight into how the world community might respond, we turn now to retired Admiral James Stavridis. He was NATO Supreme Allied Commander and now serves as Dean of the Fletcher School of Law and Diplomacy at Tufts University. Welcome to the program.
JAMES STAVRIDIS: Thanks, Arun. Great to be with you.
RATH: So Ukraine is not a NATO member but the Netherlands, which lost nearly 200 citizens in this crash, is a member of NATO. If President Putin doesn't change course, what are NATO's options?
This is WEEKEND EDITION from NPR News. I'm Arun Rath, sitting in for Rachel Martin. Pressure is mounting on Russia as international inspectors wait to gain full access to the site of last week's Malaysia Airlines crash in eastern Ukraine. World leaders are demanding that President Vladimir Putin use his influence with pro-Russia rebels so they'll allow inspectors in and allow the bodies to be recovered. Wall Street Journal reporter James Marson is following the story in Moscow and joins me on the line. Thanks for speaking with us.
