Doctor for tropical medicine Florian Steiner (R) and ward physician Thomas Klotzkowski step out of a disinfection chamber after cleaning their protective suits, at the quarantine station for patients with infectious diseases at the Charite hospital in Berlin August 11, 2014. The isolation ward at the Charite is one of several centres in Germany equipped to treat patients suffering from ebola and other highly infectious diseases, the clinic's doctor for tropical medicine Florian Steiner said. Ebola is one of the deadliest diseases known to humanity. It has no proven cure and there is no vaccine to prevent infection. The most effective treatment involves alleviating symptoms that include fever, vomiting and diarrhoea. The rigorous use of quarantine is needed to prevent its spread, as well as high standards of hygiene for anyone who might come into contact with the disease. (Photo by Thomas Peter/Reuters)

Two migrants from Guatemala sleep on the train tracks in Arriaga August 8, 2014. While the White House says the number of Central American child migrants crossing the U.S. border has fallen sharply, the big unanswered question remains why. The U.S. government has pointed to the seasonal weather. However, Reuters reporting in southern Mexico and Central America shows it is due to a combination of factors, including tighter border policing, raids on “La Bestia”, or “The Beast” network of cargo trains bound north, horror tales told by deportees who grappled with drug gangs, an advertising blitz touting the dangers of making the journey and the high-profile arrests of several human smugglers, or coyotes.
