GALVESTON, Texas, Dhu-AlHijjah 25, 1435, Oct 19, 2014, SPA -- Some of the dozens of people who are being watched for possible exposure to Ebola in the United States are expected to be cleared on Sunday and Monday, potentially easing concerns about the spread of the disease after two nurses were infected, Reuters reported. A Dallas lab worker who spent much of a Caribbean holiday cruise in isolation tested negative for the deadly virus and left the Carnival Magic liner with other passengers after it docked at Galveston, Texas, early on Sunday morning. The precautions taken for the cruise passenger reflected widespread anxiety over Ebola in the United States, including calls from some lawmakers for a travel ban on West Africa. -- SPA 21:07 LOCAL TIME 18:07 GMT www.spa.gov.sa/w
