Just a week after the World Health Organization declared that known transmissions of Ebola “have been stopped in West Africa,” at least 100 people were quarantined in Sierra Leone following the death of a woman infected with the virus. The 22-year-old’s death is particularly concerning to officials, because it appears that locals did not observe protocols put in place to stop the disease from spreading. In addition to living in close quarters to 22 other people, several individuals washed her corpse, putting themselves in danger of contracting Ebola. The outbreak of the virus last year killed more than 11,000 people in West Africa.
