Ebola has arrived in the US, though in a carefully controlled manner. A plane carrying one of two Americans who contracted the disease in Africa arrived at a military air base near Atlanta this morning, reports the Journal-Constitution. The AP says the patient is 33-year-old doctor Kent Brantly, though hygienist Nancy Writebol is expected to arrive at some point as well. Both will be treated in isolation units at Atlanta's Emory University Hospital. It's the first time any US medical facility has had an Ebola patient, notes CNN. The disease is usually fatal, with the death toll in West Africa now above 700. (While being treated in Africa, Brantly turned down an experimental serum so Writebol could get it.)
