A World Health Organization worker infected with Ebola has arrived in Germany for treatment.
The Senegalese epidemiologist was flown to Hamburg on Wednesday after contracting the virus from an Ebola testing lab in Sierra Leone.
After the infection, the WHO said Tuesday it had shut the lab in Kailahun and withdrawn its staff.
Ebola has killed more than 1,400 people and sickened at least 2,600 in West Africa since the outbreak began in March.
Among the worst affected countries are Sierra Leone, Guinea and Liberia, where the government has sealed off an entire slum in the capital Monrovia.
In Liberia, where the highest number of deaths has been reported, some government officials are fleeing the country or just not reporting for work. The situation drove President Ellen Johnson Sirleaf on Tuesday to order all ministers to return to work. Liberian officials said several ministers who defied the order had been fired.
The head of the U.S. Centers for Disease Control and Prevention, Tom Frieden, offered a cautionary assessment of the outbreak while meeting with officials in Liberia. Frieden will also stop in Sierra Leone and Guinea.
