American woman with Ebola is smiling
Washington - The American woman who was sickened with the dangerous Ebola virus while working with a Christian aid group in Liberia is getting better and is even smiling, her son said on Tuesday.
Nancy Writebol, aged 60, was evacuated from Monrovia last week and was wheeled on a stretcher into a special isolation unit at Emory University Hospital in Atlanta, Georgia.
"When she came in on Tuesday last week, we were really concerned that she wasn't going to make it," Jeremy Writebol said on NBC's Today Show.
"To see her wheeled out of the ambulance and in, I was on the floor sobbing."
Writebol and American doctor Kent Brantly are among the more than 1 700 people who have been sickened by the latest Ebola virus outbreak, which has killed more than 100 people in West Africa since March.
Brighter eyes, joking
They both received doses of an experimental drug for Ebola. Brantly, aged 33, was seen stepping out of the ambulance and walking on his own.
Writebol was in poorer condition than Brantly on arrival, but has since improved. Her son said he is able to visit her twice a day.
Due to concerns about contagion, he can only look at her through a hospital window, as doctors and nurses treating her don protective gear from head to toe.
"We've seen her get physically better, her eyes brighten up, smiling, even joking a little bit," he said, adding that doctors have told him they are cautiously optimistic about her recovery.
Writebol's husband, David, returned to the US from Liberia on Monday. He remains in isolation, checking his own temperature multiple times a day for signs of fever.
Ebola symptoms can emerge two to 21 days after exposure to the virus, causing fever, muscle aches, vomiting, diarrhea, and sometimes internal and external bleeding.
A total of 1 013 people have died and 1 848 people have been infected since March, according to the World Health Organization's latest tally on 11 August.
Nearly 55% of victims have died in the outbreak, which has spread to Guinea, Liberia, Sierra Leone and Nigeria.
