The son of a North Carolina-based missionary says his mother is fighting the Ebola virus while in isolation in Liberia.
Jeremy Writebol in Wichita, Kansas, told NBC's "Today" show Wednesday that he's been able to talk with Nancy Writebol as she fights the illness.
He says his mother is able to move around the home where she's in isolation and has been able to get plenty of fluids.
A statement from Samaritan's Purse on Wednesday said Writebol and Dr. Kent Brantly both remain in serious condition. Writebol is a missionary with SIM. Brantly is a doctor from Texas working for Samaritan's Purse.
The Writebols' church in Charlotte, North Carolina, planned a prayer service Wednesday night for the two.
Meanwhile, Samaritan's Purse is making arrangements for nonessential personnel to leave Liberia.
