Although many of the Cubans on the Ebola mission speak limited English, their sense of commitment appears to have impressed other aid agencies. One Cuban doctor, Felix Baez, who became infected Ebola while working at Kerry Town, returned to Sierra Leone earlier this month after being treated in Geneva. "He was also treated at British Army clinic in Kerry Town, where they took very good care of him," said Mr Bustillo. "He wants to finish the job he started."
