The Democratic Republic of the Congo has confirmed an outbreak of Ebola, which has killed at least 13 people. The country’s health minister said the outbreak was not linked to the one impacting four countries in West Africa. That outbreak has killed more than 1,400 people, which the World Health Organization acknowledges is an underestimate. An epidemiology expert sent by the WHO to Sierra Leone has contracted Ebola there, as has a British nurse who has been transported back to London. Sierra Leone has made harboring Ebola victims a crime punishable by up to two years in prison.
