Liberia's chief medical officer is placing herself under quarantine for 21 days after her office assistant died of Ebola.
Bernice Dahn, a deputy health minister who has represented Liberia at regional conferences intended to combat the ongoing epidemic, said on Saturday that she did not have any Ebola symptoms but wanted to ensure she was not infected.
The World Health Organization says 21 days is the maximum incubation period for Ebola, which has killed more than 3000 people across West Africa and is hitting Liberia especially hard.
WHO figures released on Friday said 150 people died in the country in just two days.
Liberia's government has asked people to keep themselves isolated for 21 days if they think they have been exposed. The unprecedented scale of the outbreak, however, has made it difficult to trace the contacts of victims and quarantine those who might be at risk.

"Of course we made the rule, so I am home for 21 days," Dahn said on Saturday.
"I did it on my own. I told my office staff to stay at home for the 21 days. That's what we need to do."
Health officials, especially front-line doctors and nurses, are particularly vulnerable to Ebola, which is spread via the bodily fluids of infected patients.
Earlier this month, WHO said more than 300 health workers had contracted Ebola in Guinea, Liberia and Sierra Leone, the three most-affected countries. Nearly half of them had died.
