MASSESSEHBEH, Sierra Leone—It had been five months since an Ebola death when Musa Kamara traveled to his hometown for festivities to mark the end of Ramadan. Not long after his sudden death in this roadside village, authorities came with a grim message: The killer virus was back.
Soon officials barricaded this community of nearly 600 people, putting up orange plastic fencing to quarantine half the town for the 21-day Ebola incubation period after potential exposure.
