By Rich McKay ATLANTA (Reuters) - An American doctor stricken with the deadly Ebola virus while in Liberia and brought to the United States for treatment in a special isolation ward is improving, the top U.S. health official said on Sunday. Dr Kent Brantly was able to walk, with help, from an ambulance after he was flown on Saturday to Atlanta, where he is being treated by infectious disease specialists at Emory University Hospital. "It's encouraging that he seems to be improving - that's really important - and we're hoping he'll continue to improve," said Dr. Tom Frieden, director of the U.S. Centers for Disease Control and Prevention (CDC) in Atlanta. Frieden told CBS's "Face the Nation" it was too soon to predict whether Brantly would survive, and a hospital spokesman said Emory did not expect to provide any updates on the doctor's condition on Sunday.
By George Tanber TOLEDO Ohio (Reuters) - Health authorities tested water for toxins in Toledo, Ohio, on Sunday as some 400,000 people remained without safe drinking water for a second day following the discovery of high toxin levels from algae on Lake Erie. Toledo Mayor D. Michael Collins said some sampling showed decreased toxin levels but results from further tests would not be known until later in the day. The city is waiting on water samples being analyzed at Environmental Protection Agency labs in Cincinnati. About 500,000 people get water from the contaminated source but about 100,000 residents of some communities have backup water supply systems, said city of Toledo spokeswoman Lisa Ward.
