The vice-president of Sierra Leone has put himself into quarantine after one of his bodyguards died from Ebola. Samuel Sam-Sumana said he would stay out of contact with others for 21 days as a precaution.
There was optimism the virus was on the decline in Sierra Leone at the end of last year but there has been a recent increase in confirmed cases.
Nearly 10,000 people have died in the outbreak, the vast majority in Guinea, Liberia and Sierra Leone. So the vice-president is taking no chances.
